How does keyword density in the title tag affect search engine placement? On Facts about Title Keyword Density, it says that Live.com rewards high keyword density in a title tag, whereas Google.com punishes high keyword density in a title tag.

I don’t really care about search engines other than Google. I’ve heard SEO experts claim that Yahoo! and MSN/Live still contribute a fair number of clicks, but that’s not true according to my server stats. I’d like to find out if Google really does punish keyword density in a title tag.

I created 3 similar pages for a fictional person, whose name currently return zero results in Google. Using the name as the search term, there are 3 different keyword weights.

1. Test A (100%)
2. Test B (50%)
3. Test C (9%)

This may not be the best test methodology, but at least it’s a start. In a few days, I’ll see how Google ranks them. Any opinions on how the pages will rank?
