Kgen for Firefox is a Firefox plugin that allows you to scan a page and then it tells you how many times a certain keyword is listed on that page. You can then copy those words to clipboard and decide what to do with them later. Its interesting to see what keywords and how many times a certain keyword is listed on a site that gets listed high on search engines for that keyword. I went over to wikipedia searched for the keyword blog since if you type in blog on google you get wikipedia listed first. The keyword "blog" is used 87 times in that one article. But you must remember that many sites link to this page as well which could be a factor for it rating so high. Anyway the plugin lets you check the following: Keywords in a cloud It's got some great options And then tags, attributes, uri, ignore list You can download the plugin here
