Hello BHW, I have a good solid old domain with a good PA/DA and other metrics, on top of that I run a site on this domain for a year and never had any problems. I built max 30-50 links to my pages. I have 2 pages that are ranked top 3 for a good keywords that brings me like 70-80% of traffic for 6-7 months. But recently when I search for this keywords I see that my site has lost the previous position on google and I can only find my index site ranking for that keywords instead targeted inner page. http://domain.com/ - without inner page that it used to be on googles front page. I experienced the same problem before with over-optimization. But, this is something different. Any thoughts? Btw. I checked google WMT and I don't have any messages.
