I am working on a project where I have to find out the keyword density of the page on the basis of URL of that page,But I am not aware actually how to begin? and also how can we create a PHP script which will fetch the keyword density of a web page.who can give me a train of thought.the more detail,the better.thanks in advance.

Hire a programmer!

Don't know if this works as I never use it, teakdoor.com/view.php?pg=keyword_density_checker
