Keyword Density

We can't emphasize enough the importance of including keyword-rich content on your site to increase your ranking potential. Simply put, keywords are the words and/or word phrases people use when searching. As we've mentioned throughout the site, search engine spiders love content. Therefore, the more keyword-rich content you have, the better. When a search engine spider crawls your site, it won't recognize pictures or images.
So, if you have limited amounts of text (or none at all) and you've got a lot of beautiful pictures or Flash animation, the spider may deem your site unworthy of listing.
