Credit: Patrick Milan, et al. ©2013 American Physical Society “Looking at an operating wind turbine, one may get the impression that the turbine turns smoothly, but looking at the power output, which is the consequence of the forces and torques inside the machinery, we see that the fluctuations are very turbulent,” Peinke told Phys.org. “Changes of MW (more than one thousand horsepower) in seconds become obvious. Thus one may compare a wind turbine with an airplane in the landing phase during a very windy situation. From outside, the airplane may look it’s going quite smoothly, but inside there is another impression caused by turbulent dynamics. One should also note that a wind turbine has to operate permanently in this ‘turbulent landing’ condition.” Citation: Wind turbines operate under great turbulence, with consequences for grid stability (2013, April 19) retrieved 18 August 2019 from https://phys.org/news/2013-04-turbines-great-turbulence-consequences-grid.html Journal information: Physical Review Letters Copyright 2013 Phys.org All rights reserved. This material may not be published, broadcast, rewritten or redistributed in whole or part without the express written permission of Phys.org. The model also reveals that moderately intermittent wind power is converted to highly intermittent power output. In other words, wind turbines do not only transfer wind intermittency to the grid, but they also amplify it. For instance, the researchers observed that changes in wind speed of about 11 m/s within 8 seconds may cause nearby wind turbines to change their power output by about 80%. The researchers attribute this amplification to the nonlinear conversion process and fast reaction time of the output to changes in wind speed.”The features of small-scale turbulence are mapped by the wind turbines directly into the electric grid,” Peinke said. “As turbulence and in particular the statistics of small-scale wind fluctuations are still considered to be an unresolved problem, this lack of knowledge may become important in the power grids, especially if such power grid are dominated by wind power. As these phenomena take place in the range of seconds, the dynamics of the power grid in these time scales have to be investigated in detail. One has clearly to state that the first step to solve a problem is to be aware of it and to understand it.”The data also shows that wind power intermittency does not only affect the output of individual turbines, as previous research has shown, but it also extends to entire wind farms, which has not been observed before. The researchers explain that wind farm intermittency is somewhat counterintuitive, since it might be expected that summing the output of wind turbines will average out their turbulent fluctuations. However, wind farm intermittency may be explained by long-range correlations observed in winds. While the wind farm the scientists observed covered an area of about 4 km2, wind correlations have previously been observed to extend to lengths of hundreds of kilometers. Based on these observations, the researchers expect that wind farm intermittency effects may persist up to these large scales.Overall, the physicists conclude that their results stress the importance of accounting for the intermittent and multifractal nature of wind power when designing components for wind power, including energy storage technologies. They note that the situation is similar to the findings from many years ago of the intermittent and multifractal nature of the stock market. In both areas, frequent occurrences of fluctuations must be understood and accounted for in order to maintain stability and avoid widespread disruption.In the future, the researchers plan to further investigate the consequence of wind turbulence on grid stability and develop methods to minimize the negative effects. New turbulence models may help lead to new concepts that reduce the power and load fluctuations on the grid.”For all of these topics, a deep and comprehensive understanding of the complexity of turbulence is indispensable,” Peinke said. Explore further Using fluctuating wind power (Phys.org) —While previous research has shown that wind turbulence causes the power output of wind turbines to be intermittent, a new study has found that wind turbulence may have an even greater impact on power output than previously thought. The researchers modeled the conversion of wind speed to power output using data from a rural wind farm. The results showed that the intermittent properties of wind persist on the scale of an entire wind farm, and that wind turbines do not only transfer wind intermittency to the grid, but also increase it. The findings highlight the importance of fully understanding the physics of wind turbulence in order to ensure future grid stability. The researchers, Patrick Milan, Matthias Wachter, and Joachim Peinke, at the ForWind—Center for Wind Energy Research at the University of Oldenburg in Germany, have published their study “Turbulent Character of Wind Energy” in a recent issue of Physical Review Letters.In their paper, the researchers address the challenges that large-scale wind energy production may bring to future power grids. They explain that today’s grids are powered mainly by a few large generators with controllable input (mostly gas, coal, hydraulic, and nuclear power plants). Power generation from these sources can be modified automatically in order to balance power generation and consumption, and thus ensure grid stability. But while today’s power sources are largely controllable, wind power is uncontrollable and highly intermittent. For time scales larger than several minutes, the conversion of wind speed into electrical power can be modeled by a standard average power curve. But at smaller time scales, the researchers found that the conversion process diverges from this curve. Instead, short-scale conversion follows a more complex pattern involving multifractal scaling that is reminiscent of a 1962 theory of turbulence developed by mathematician Andrey Kolmogorov.

Hope in colours and canvas

first_imgSome extra faith can never be a bad thing. The core theme of Ekta Jain’s paintings is  ‘Hope and never to despair’. The illuminated niches , rays of sun lighting up the dark crevices, beams of radiance dispelling the gloom are subtle statements occupying the focal point in her creations.Jain’s artwork is autobiographical and bears a close resemblance to her ‘never say die’ spirit and cheerful demeanor, finding vivid translation in her  formations and fabrications on the canvas. Her abstracts are reflective of hope and faith; of assurance and conviction of trust and optimism. Also Read – ‘Playing Jojo was emotionally exhausting’There is a symmetrical oneness in her apparently diversified expressions like her name ‘Ekta’ which implies unity, uniformity, solidarity and homogeneity. Her play with colours started at a tender age till it metamorphosed into emphatic narrations. Her journey to urban spaces is punctuated by her desire to discover layers upon layers of soul’s responses to civility or lack of it. The innate desire led her to formulate and execute her concept without any formal exercise in art.Her paintings are like palimpsest. Elusive at times and evasive but at the end of it the works come across as strokes of hope and happiness.last_img read more

Junk food causing brain health to decline faster

first_imgThe average person eats many more calories than they did 50 years ago — equivalent to an extra fast-food burger meal every day – which is causing brain health to decline much faster, a study has found. A study reports about 30 per cent of the world’s adult population is either overweight or obese, and more than 10 per cent of all adults will suffer from type 2 diabetes by 2030. “People are eating away at their brain with a really bad fast-food diet and little-to-no exercise,” said researchers. Also Read – Add new books to your shelf”We’ve found strong evidence that people’s unhealthy eating habits and lack of exercise for sustained periods of time puts them at serious risk of developing type 2 diabetes and significant declines in brain function, such as dementia and brain shrinkage,” researchers added. “The link between type 2 diabetes and the rapid deterioration of brain function is already well established,” they said. “But our work shows that neurodegeneration, or the loss and function of neurons, sets in much, much earlier – we’ve found a clear association between this brain deterioration and unhealthy lifestyle choices,” researchers added. “The damage done is pretty much irreversible once a person reaches midlife, so we urge everyone to eat healthy and get in shape as early as possible — preferably in childhood but certainly by early adulthood.” A standard fast-food meal of a burger, fries and soft drink is about 650 kilocalories — roughly the extra amount that people worldwide, on average, are consuming everyday compared to what they were eating in the 1970s.last_img read more

Massive Oil Painting by Old Master Unexpectedly Found Behind a Wall in

first_imgParis is one of the most glamorous cities in Europe and Oscar de la Renta one of the most exclusive fashion chains in the world, but while preparing to open a new store they uncovered a level of class and sophistication that their rivals would have killed for. According to the New York Times, while the building was being renovated Oscar de la Renta chief executive Alex Bolen got an excited call from his architect, Nathalie Ryan.Oscar de la Renta. Photo by Matti Hillig CC BY-SA 3.0Ryan had come across something jaw-dropping hidden behind a wall on the second floor of the 19th century building they had acquired on Rue de Marignan, a side street off the luxury Avenue Montaigne which is home to stores from the likes of Louis Vuitton, Dior, Chanel, Valentino and Ralph Lauren.Bolen hopped on a flight from his New York office and was taken to see what Ryan had discovered: a 10 by 20 foot oil painting filled the entire length of the wall. It showed an elaborately dressed 17th century aristocrat and his courtiers entering the Holy City of Jerusalem — the golden domes of the mosques visible in the background.The Dome of the Rock (Qubbet el-Sakhra) is one of the greatest of Islamic monuments, it was built by Abd el-Malik, Jerusalem, Israel.The second floor had previously been home to an insurance brokerage, and Ryan’s team had been working flat out to strip out the soulless office interior for something worthy of a high end fashion boutique. Pretty much everything would have to go from the cubicle hell and they envisaged an elegant grand staircase that would link the two floors, creating one big open shop space.As soon as Ryan — who used to be Dior’s in-house architect — began work, they began to find evidence of the building’s former grandeur. Hidden above the sterile office ceiling, a workman had found a 19th century wood panelled ceiling of 29 recessed squares, eight of them painted with heraldic devices, and all perfectly preserved.It was beautiful, but not uncommon in buildings of that age in Paris — however the oil painting was something else entirely.The mysterious painting was an oil on canvas by Arnould de Vuez.“Oh my God, it was — wow,” Ryan told the New York Times. “Sometimes when you work on castles, you find something, but usually it’s a hidden fireplace, or in Italy, maybe a fresco,” Ms. Ryan said. “But in an apartment? In a store?”“Everyone freaked out,” said the boutique’s interior designer Jeang Kim. “It was like finding a mummy. I turned off my phone immediately and just looked at it. Nothing like this had ever happened in my work before.”Demolition was halted and Bolen set about investigating. Through the well-connected de la Renta family who own the company he was able to make contact with members of the distantly related de la Rochefoucauld family — one of whom lived in the building opposite the boutique and another who worked at the Louvre, the world’s largest art museum which is located in the heart of Paris.Musée du Louvre, Paris, France.Bolen was then introduced to art historian Stephane Pinta of the Cabinet Turquin, an expert in the old masters, which refers to art created by professional artists prior to 18th century, including the Renaissance and Baroque schools of art.Pinta revealed that the mysterious painting was an oil on canvas by Arnould de Vuez, who worked with the acclaimed Charles le Brun — painter to the French king Louis XIV and interior designer for the royal palace, Château de Versailles. De Vuez didn’t get a chance to mingle with the same high society — he made the wrong enemies and was forced to flee France for Constantinople, now Istanbul, then the capital of the Ottoman Empire.Pinta discovered a reproduction of the painting in the 1900 book Odyssey of an Ambassador: The Travels of the Marquis de Nointel, 1670-1680. It told the story of Charles Marie François Olier, Marquis de Nointel, who was French ambassador to the court of Ottoman emperor Mehmed VI.Mehmed VIWith Franco-Turkish relations at a low, the marquis went to impress and arrived in the company of four battleships and 27 French noblemen. His mission was a modest success — he secured lower customs charges for French merchants to the east and visited Greece, Palestine and Egypt. His obsession with acquiring precious antiquities was less well received, and having racked up enormous debts on behalf of the crown he was ordered home by Louis XIV.The mystery painting shows the marquis arriving in Jerusalem with great ceremony and pomp as part of this over-indulgent diplomatic tour-turned-shopping spree. In that respect, at least, the Marquis de Nointel is a worthy guardian angel for a fashion boutique where dresses start at around $1,600 and rocket to well over $4,000. Bolan agreed with the buildings owners to restore the painting — which was darkened by varnish and earlier attempts at restoration — in exchange for it remaining in the Oscar de la Renta boutique for its ten year lease.Read another story from us: The TIME Persons of the Year that Caused the Most ControversyUnderstandably the plan for the store has been modified too, with extra security in place, period furniture being ordered, and treated glass being installed on the windows to prevent sunlight from damaging the painting.“We’re not going to put a wall of dresses in front,” joked Ryan.last_img read more

Bringing the Ancient Athenian Trireme Back to Life – The Story of

first_imgThe Hellenic Navy has a full-scale working reconstruction an ancient Greek trireme which floats in the waters of the Saronic Gulf and is a must-see for anyone visiting Athens or the Port of Piraeus. Her most recent voyage was on September 28th and 29th, 2018, to commemorate The Battle of Salamis, a decisive victory of the ancient Greek fleet over the Persian navy — in which the trireme was key to the Greek victory. A trireme is a fast, maneuverable type of galley with three banks of oars and a formidable ram at its prow, which was used by several different cultures of the Mediterranean. The design of this type of warship was perfected by the Athenians, and with it, their fleet dominated the Aegean Sea.Trireme Olympias: conjectural reconstruction after the work of J.S. Morrison, J.S. Coates and F. Welsh. Now at the Paleon Faliron Museum of ancient marinery.In 1982, naval architect John F. Coates joined forces with historian J.S. Morrison and classics teacher Charles Willink to create the Trireme Trust, with the goal of constructing an accurate replica of an authentic trireme. By 1987, the HS Olympias, built over two years by a shipbuilder in Piraeus, was ready for her first sea trial.The ancient Greeks were a collective of city states, united by their language and culture, and most importantly by their navy. Despite the widespread use of the trireme, no surviving examples have been recovered. In 2018, the Black Sea Maritime Archaeology Project announced the discovery of an intact 75-foot vessel dated to 400 BC that could be a Greek trireme, however the wreck is too delicate to be brought to the surface.The stern of Trireme Olympias. Photo by Templar52Coates developed the drawings for their project based any resource he could find, including historical writings that describe the ships, archaeological evidence, and ancient art such as book illustrations and painted pottery.The project was very expensive and financed by the Hellenic Navy, as well as individual donors such as Frank Welsh, a banker and trireme enthusiast who was a major financial backer of the Trireme Trust.The museum of Ancient Greek Trireme Olympias (Replica). Photo by Templar52In part, the team were inspired to embark on the project simply to prove that it could be done. As the Trireme Trust website reports, “A series of six sea-trials between 1987 and 1994 demonstrated that the ship could be rowed efficiently and fast, despite almost universal academic opinion that a three-level arrangement of oars was wholly impracticable.”She was crewed during sea trials by volunteers who took up the 170 oars. The reconstructed trireme was able to reach a top speed of nine knots. They were unable to maintain the cruising velocity of seven knots that the ancient Greeks achieved, according to Owlcation.The bow of Trireme Olympias. Photo by Templar52Olympias can also perform some clever maneuvers such as turning itself around 180 degrees in just one minute, confirming the authenticity of historical accounts.Virginia oak, Oregon pine, and an Iroko hull were used for building the trireme. It was adorned with a bronze bow ram weighing 441 pounds. The ram was based on an original model, part of the collection at the Piraeus archaeological museum.Olympias was built as a test model, adapted for recreational sailing instead of attack. Originally, triremes were aggressive, fast ships, meaning that they were built as light as possible. Also, they were very long, in order to fit in so many oarsmen.Replica of Trireme Olympias of the Hellenic NavyThe only thing that made the triremes susceptible to stress damage was the waves. Therefore, a hypozomata (bracing rope) was firmly fixed beneath the deck, tying the two ends of the ship (bow and stern) together. On Olympia a steel rope was used as the hypozomata due to a lack of natural fibre ropes with the same elasticity as hemp, the material that was originally used for making the bracing rope.Rather than exerting constant tension like a natural fibre rope, the steel cables tension varied as the hull bent on the waves. Consequently, protective measures had to be taken, as there was an alarming possibility of the rope breaking and endangering the crew.Read another story from us: Research Team Close to Finding Antarctica’s Most Famous ShipwreckIn 1993, Olympias was proudly sent off to Britain where it took part in the celebration of 2,500 years since the beginning of democracy. In 2004, she carried the Olympic Flame from Keratsini to Piraeus for the Summer Olympic Games in Athens.The successful reconstruction of the trireme is considered to be of extreme archaeological importance.

first_imgBrits are well known for their humor. But what happens when you find some of it in officially written legislation — ridiculous rules bound by law not to break them? Well, British journalist Oobah Butler took it upon himself to break some of those weird laws — and he got away penalty-free. Among other things, he beat a doormat after 8 am, an act not allowed on the streets since 1839, and he also walked around the city with a dead fish clutched in his hand, Vice Magazine reports.While some of this legislation may have made sense on the day it was passed in parliament, today these laws feel more like the subject of a good laugh. A few of those listed below sound like they could be true, considering some of the real laws, but are in fact widely-believed urban legends.Carrying a plank on the pavementA drawing depicting the old Palace of Westminster, which suffered in a fire in 1834. In the foreground, the Old Palace Yard.You are allowed to unpack a plank from your vehicle, but you better have a good explanation if you plan to carry one while walking down the pavement (sidewalk) anywhere in London. Section 54 of the Metropolitan Police Act not only bans you from carrying a plank on the pavement but also a bunch of other stuff such as hoops, ladders, and wheels. Originally introduced in the 19th century, this law was aimed to restrict annoyance in the public and allow the easier passage of pedestrians.Singing any profane, indecent, or obscene song or balladWestminster Bridge and Houses of Parliament, circa 1910There are a number of ways to disturb the public and end up in trouble with authorities, such as flying a kite or singing not the right song. The Metropolitan Police Act of 1839 also states that a person is not allowed to “sing any profane, indecent, or obscene song or ballad, or use any profane, indecent or obscene language to the annoyance of the inhabitants or passengers.” Perhaps this is one section that should be enforced more rigorously today.No obscene language when in the library and no gamblingThe UK Libraries Offences Act 1898 sets out the punishments for misbehaving in a public libraryAs the UK’s Libraries Offences Act 1898 dictates, there ought to be consequences for any person who “behaves in a disorderly manner” when in a library or reading-room. Usage of “violent, abusive, or obscene language” is one of the possible offenses under this act, and gambling falls under behaving in a “disorderly manner.” Punishment may also befall the library-goer who “after proper warning, persists in remaining therein beyond the hours fixed for the closing of such library or reading-room.”Handling a salmon in suspicious circumstancesAtlantic salmon, Salmo salar (handled in non-suspicious circumstances)While a law from 1986 to prevent the sale of illegally caught fish (Section 32 of the Salmon Act, titled “Handling Salmon in Suspicious Circumstances”) may have had good intentions, the wording tosses it deep into weird waters.“A five-hour House of Lords debate about the issue in February 1986 decided the wording would protect unwitting people from the then-in-place wider law of ‘possessing salmon which have been illegally taken, killed or landed,’” according to the BBC. However, written the way it is it indeed gives the impression that people walking around holding a suspicious-looking piece of salmon in their hand is a common sight.Related Video: Victorian Slang Everyone Should KnowWhales and sturgeons belong to the QueenQueen Elizabeth II attends the wedding of Prince Harry to Ms Meghan Markle at St George’s Chapel, Windsor Castle on May 19, 2018 in Windsor, England. Photo by Pool/Max Mumby/Getty ImagesThere is much legal enforcement associated with fish in the UK. For example, whales and sturgeons are considered to be royal fish, thus any caught in UK waters are immediately consigned on behalf of the current reigning monarch of the nation, in this case, Queen Elizabeth II.Ownership of all whales, sturgeons and dolphins has been part of the royal prerogative ever since the reign of King Edward II, who sat on the throne some seven centuries ago.Importing Polish potatoes might be a problemMap and flag of PolandNot only the fish could be suspicious in your typical British dish of fish and chips, but also the chips themselves. Especially if the potatoes come from Poland. Unless certain things are done ahead of the import.Fresh organic potatoesBefore importing Polish potatoes into the United Kingdom, you need to provide authorities with a number of details. These include the border entry point, date and time of proposed entry, details of the means of transport, how many and where they will be taken. Also, not to forget the variety of the potato, the ID number of the person who grew them, and a ring rot certificate proving the potatoes are not diseased. The Polish Potato Order 2004 came into force after Polish potato crops suffered from a series of outbreaks of ring rot disease.Don’t let down the Queen. Not even on postage stamps.Postage stamps from 1952 showing a young Queen Elizabeth IIAccording to Britannica.com, treason is defined as “the crime of betraying a nation or a sovereign by acts considered dangerous to security.”The case might be that treason is also putting a postage stamp with the face of the Queen upside down on the letter. Luckily, letters are going out of fashion these days. And luckily again, this aspect of the law is just one of the legal myths flying around.This postage stamp violation has been somehow associated with the Treason Felony Act 1848, which considers anything that could be interpreted as treason an offense, particularly acts to depose the monarch — although no mention of placing stamps upside down is mentioned within the Act.A common pet dog is not allowed to mate with royal breedsA Pembroke Welsh Corgi. Photo by Bensbro CC BY-SA 4.0Queen Elizabeth II is a world-famous devotee of dogs, in particular her very own royal lineage of Pembroke Welsh Corgi. However, if you happen to randomly stumble upon her while walking your own dog (which is kind of hard to imagine) watch out! Word has it a common pet dog is not allowed to get too friendly with a royal breed.While there are several weird laws associated with members of the royal family, this one is not true. Although a commoner could be prosecuted under the (now repealed) Criminal Law Act 1722 for killing a deer in the royal forests.Suits of armor not allowed in ParliamentA full suit of armor, Italian and with sallet, c. 1450Under the Statute forbidding Bearing of Armour 1313, no person is permitted to enter the House wearing a suit of armor. Not that today’s MPs are likely to keep such an outfit in their wardrobe and wonder in the morning if that should be their choice for the day.However, the statute was enacted during the reign of Edward II, in times of considerable political instability in England. In it, the King indeed insists “that in all Parliaments, Treaties and other Assemblies, which should be made in the Realm of England for ever, that every Man shall come without all Force and Armour.”It is supported by The Statute of Northampton 1328, which prevents any person “except the king’s servants in his presence, and his ministers in executing of the king’s precepts, or of their office” from carrying weapons in public.Carrying at least one bale of hay in your vehicle was mandatoryLast but not least, in the old days, city transport depended on horse-drawn carriages. A bale of hay always at the disposal of the driver could have indeed helped the horse. Some believe this was mandatory by law, although this one is also an urban myth.Read another story from us: 2,000-year-old Fast Food bar discovered in PompeiiAccording to the London Hackney Carriage Act 1831, it was an offense for drivers to feed their horses in the street — unless they did so from a special corn bag or offered the hay to the animal from their own hands. Both ways, it’s weird.last_img read more

VIDEO Notre Dame coach gave an expletive filled antiTurnover Chain pregame speech

first_imgMiami crushed Notre Dame, 41-8, to remain undefeated, and the biggest star of the night for The U in The U’s biggest home game in forever wasn’t a player, it was the swagger dripping “Turnover Chain.”The Chain got more airtime than anyone on the Irish, and will be the first thing people identify the game with 10-years from now, but not everyone is a fan of the chain, including Notre Dame Defensive coordinator Mike Elko.While walking on the field with his players before the game, Elko called them in to give them an F-bomb laden pregame speech, letting them know in the most explicit of terms that he was sick of all the hype surrounding the Miami defense and The Chain. He finished by saying Miami can have their chain because the Irish were “getting the f—ing rings.”Yeah, this speech didn’t age well. Last night was all about The U and The Chain.

Fighting Fee Increases

first_img Free Workshop | August 28: Get Better Engagement and Build Trust With Customers Now This story appears in the November 2005 issue of Entrepreneur. Subscribe » 2 min read November 1, 2005 This hands-on workshop will give you the tools to authentically connect with an increasingly skeptical online audience. Tired of the increasing costs of credit card transactions? A group of merchants have banded together to fight back with class action lawsuits charging Visa, MasterCard and other leading banks with illegally fixing prices on interchange fees.”The banks have become increasingly greedy with their fees, which is making life difficult for retailers and driving up prices for their customers,” explains Mallory Duncan, senior vice president and general counsel of the National Retail Federation. “Visa and MasterCard are essentially monopolies, and they are using their status as monopolies to increase profits at the expense of consumers.”Interchange fees–fees banks collect from retailers every time a credit card or debit card is used to pay for a purchase–first came under fire in 2003 when retailers won the right not to accept certain high-fee debit cards. In July 2005, Kroger Co. followed suit by banding with several other large retailers to charge Visa USA Inc. and Visa International Service Association with colluding on fees. And now small businesses are joining in with a suit filed by Robins, Kaplan, Miller & Ciresi LLP on behalf of five businesses in California, Connecticut and Minnesota alleging that banks violate anti-trust laws by conspiring to fix interchange rates.Duncan attributes the rash of suits to a seemingly arbitrary bump in interchange fees, which have jumped from a weighted average of 1.58 percent in 1998 to 1.75 percent in 2004, the NRF reports–an increase of 10.8 percent. “[Retailers’] costs are in the hands of a third party who has no incentive to keep them in check,” says Duncan.While quick to note that legal processes take time, Duncan is optimistic about the suit against Visa. “We’re talking about a case with $20 billion a year in fees at stake,” he notes. “This is major litigation filed by reputable attorneys with the potential to bring about real change.” Enroll Now for Freelast_img read more

Finding the Keywords Your Competitors Use

first_img 5 min read Free Workshop | August 28: Get Better Engagement and Build Trust With Customers Now This hands-on workshop will give you the tools to authentically connect with an increasingly skeptical online audience. In his book Ultimate Guide to Optimizing Your Website, SEO and online marketing expert Jon Rognerud shows you how to build a high-performance website and get top ranking on all search engines. In this edited excerpt, the author explains how to find out what keywords your competitors are using and how you can use that data to improve your search engine rankings.It’s important when analyzing keywords that you know which keywords your competitors use and if you’re in the proper league to either continue to use them or try for keywords that are still popular yet not used as often.Some paid keyword analyzers can tell you which competitors use which keywords, but this is often limited to what’s used for Google AdSense campaigns. A good way to determine what keywords your competitors are using is to use keyword research tools to extract keywords from their pages, and then copy and paste your selected keyword into a search engine such as Yahoo! or Google to see where they show up.An easy way to find target keywords for your competitors is to see what Google thinks they are by using the new interface to Google Keyword External tool (updated to look and act like the version supplied within Google AdWords.) The new keyword tool allows you to select languages, local search targets and more.Use these steps to discover keywords from competitor domains:Access the keyword tool and log in.Input your competitor’s web address.Review the listings, and scroll down to view all and see the collection of keywords including ad group ideas.You would pick the keywords that have (exact) search counts and that closely match your site as a starting formula. A combination of head and long-tail keywords should be included in an Excel tracking sheet. As you enter some of these keywords into Google, you’ll see varying results for paid results. These will help you understand how “commerce viable” a keyword is. The more ads, the more you can consider it to be a moneymaker. You can further input top keywords into Spyfu.com and Keywordspy.com to discover more detail, including potential paid campaigns and their resulting landing pages. This will give you a broad view of your competitor’s use of keywords, pages and overall strategy.For each of the top five sites, select keywords that seem reasonable, match your market and have search volume, and then take a look at the results that come up. Don’t worry as much about the sponsored listings, as these spots are out of your league if you have limited funds. Expand the research, and focus on the first ten direct listings of the search engine results. Ask yourself: Do these listings relate to the keyword at hand?Having the exact keyword phrase in your title helps you rank better with search engines. Additionally, you can check on the number of inbound links of these sites. Use LinkVendor to do this. If you have a Google webmaster account (you should!), your incoming links will be revealed there. Rather than simply hunting down links, however, search for quality links back to you, which are of higher priority. The search engine will return how many inbound links the website has. Make sure to select the “Except from this domain”–we want to show only external links, not links within the site.Now, what do you do with all this information, particularly if the number is high? Even if the number of inbound links is in the thousands, you don’t necessarily have to discount a keyword. In order for inbound links to be useful for search engines, they must relate to the keywords used throughout your website. For example, if you’re looking to rank well for refinancing loans yet your inbound links are for subprime mortgage loans, you’ll get a good search engine ranking for subprime mortgage loans rather than what you originally wanted, which was refinancing loans. A solid information architecture with keyword research to build out your pages will help avoid this problem. You’ll make sure that you target pages across your site, not just your homepage.You’ll get some legitimate traffic, since some subprime loans are also refinancing loans, but the traffic wouldn’t be as relevant as if you had inbound links that related directly to refinancing loans. If this is what’s happening with your competitor’s keywords, you can take advantage of it by creating a site with the appropriate inbound links.How can you determine if a competitor’s inbound links relate to the keywords used on its site? OpensiteExplorer.org will show your competitors’ anchor text and a lot more around domain authority, diversity of linking domains, which is important, and total links.A powerful tool that you can try on a 30-day free trial is Market Samurai. It provides a complete, integrated system for all online marketing efforts, and it’s a killer tool. The link analysis can show you all incoming links sorted by page rank or by anchor text use, and can easily be exported. Find out who they are, and submit for a link. You may be surprised to find out that top, or first page, listings of Google have low page rank values but extremely targeted page and anchor text matches. This is a big secret to success.You can effectively compete even if a site has a smaller number of legitimate inbound links. The key is to ensure that your links directly relate to the keywords used on your site; if your competitors don’t, you may be rewarded with top placement.
