My little corner on free seo help
It is a known fact that some keywords are more popular than others but are also being sought more competitively in web page rankings. So it may well be a better strategy to choose lesser popular keywords which may help your website rank higher on a search list. There is a very close similarity between keywords and movie stars. They have a shelf life, their five minutes of stardom. So what was a 'buzzword yesterday may be out of fashion today and thus may not figure in the ranking list of search engines.
