So, I have a 2 year old site that just disappered from PG1 on google's results list. What gives? My site is stll indexed, and the adsense is still working, but I can't find the site now when I query on my keywords.
Adsense has nothing to do with how well your site ranks in the search engine result pages. It may just be that your competitors have more back links and better SEO than your site does.
