It has been 9 months since I started a simple test to answer a question about what is more important - keywords in url or backlinks by trying to rank for an imaginary keyword "goodroipow" [webmasterworld.com
It was very interesting for the first few days to watch how Google crawled new pages and updated their results. Then it became interesting to watch how sites were scraping the content and how Google responded to that.
I have one question for you: What have you been testing? ps I am curious to see how this post ranks in Google for goodroipow or if they will just filter it out. Update July 22 - goodroipow.com is live, with almost no links to it. I did mention it in twitter. As for people curious about my findings, I strongly suggest you watch the serps and form your own opinion. Some things to pay attention to #1 how links impact ranking, #2 how keyword placement imacts ranking (in content, title, domain, url) #3 how users impacts rankings.
