For a long time, 2-3 years, I had the term mind power somewhere between number 1 and number 5 in the serps.
Now I'm not even in the top 50 and it's a result of google changing. Go do a search on mind power and see what google likes now for that term. I checked it a few days ago thru the top 15 and didn't like what I found. Only 2 of the top 15 had adsense ads and most are affiliate sites selling their own stuff. Even one around number 9 that's really spammy with the keywords.
I still have some top 10s but about half of the pages that used to be in the top 30 are now not in the top 100. Adding links didn't help and neither did changing the pages and adding more text.
Lol, I'm thinking of removing adsense from the site and adding affiliate links and banners to see what happens.
The original site is at http://www.mentalpowerandthemind.com/
Any ideas of what's happening there, Mike?
