Mike2010 claimed that meta keyword helped his page rank where the keyword was his domain name, therefore it was "mentioned" elsewhere on the site
#1 it wasn't a popular phrase at all , thus the reason for it to be pulled from nowhere to be found (in google).... to #1.
#2 Unless you have a really good 1 word domain name, I don't see a reason why people would place their domain name in other parts of their site when it's 2 or more words...and placing it without a space. That domain was 2 words. So I did not have it mentioned anywhere else on the site. Not in meta description, not in title, not in the text on the site or anywhere. Placing it in meta keyword was the only place it was placed. And like I said, within a week it boomed to #1.
Just that single instance did it. You'd figure since it was an unpopular phrase and part of the domain, google would automatically give it weight for rank. But it did not. Until placed in meta keyword.
I'd recommend others try the same if they have a domain hangin around for testing.
thinking about removing it and seeing if rank disappears again..
