Today I was listening to some teleseminars delivered by my friends Patsi Krakoff & Denise Wakeman of The Blog Squad . They were talking about optimization of blogs. I have to admit that I didn’t understand the whole concept behind key word density and how it related to optimization. I just didn’t get how important it is for both a blog and a website. That is, until I was listening to them.
"Keyword density is the percentage of words on a web page that match a specified set of keywords. In the context of search engine optimization 
keyword density can be used as a factor in determining whether a web
page is relevant to a specified keyword or keyword phrase. Due to the
ease of managing keyword density, search engines  usually implement other measures of relevancy to prevent unscrupulous webmasters  from creating search spam  through practices such as keyword stuffing ."
Okay, so density is just part of the whole equation. Then, somehow I stumbled across a FREE tool to see how "dense" keywords are on a blog or website. http://www.keyworddensity.com 
Test your own blog or website. Are your keywords dense enough to attract search engine spiders?
What other tools do you know about to increase your visibility?
