I found this post this morning and thought I would give it a share. The information on it answers just about every SEO question there is, so prepare for a long read
It tells you about every aspect of your page, from page size to keyword density to the design of the site as well.
I know we all have our own ideas about SEO and optimization so, read through the post here: Optimization and let me know what you think. I've bookmarked it for future reference as wellThe same keyword repeated one after the other a few times, for example air tickets on-line, air tickets, air tickets, air tickets, air tickets in Hong Kong is a questionable trick. For this example, there will be three repetitions reported, because the keyword was placed three times in a row after it was used first. Such repetitions are considered as spam by most search engines.
