make sure that all of your indexed pages are of the highest quality possible and that they are fantastic representatives of your website
JohnMu then gave some examples of very thin pages. It is about a site with 99% of such pages and problems with spammy UGC. Not about maximizing search advertising revenue. It is about quality like described in: http://googlewebmastercentral.blogspot.com/2011/05/more-guid...
I'd like if there was a traffic graph (is an algorithmic penalty visible, trends, or are they just down to 10% of 1.5 years ago?). We have to go by word and own research now. Googling "Google Maps Mania" shows a botched domain transfer as a likely culprit for the low rankings/visitors. The redirect is not 301. Old pages do not redirect to content on the new domain ( http://www.mapsmaniac.com/2013/02/beneath-thunderdome.html ). So any links to mapsmaniac before the domain transfer do not contribute to the new blog at googlemapsmania.blogspot.com . Domain authority is zero'd out. Many well-ranking pages now show a "Page not Found" to Google. Then another site pops up on another domain with the same name. How can Google know for sure the two are from the same owner if the redirects are not set up right?
Fix the redirect. Restore the old links and redirect them to the new site. But maybe much of that is already too late for them. For anyone else in the process of moving a site, see: http://www.mattcutts.com/blog/moving-to-a-new-web-host/
