The story of how this happened is very interesting. PSD2HTML was one of the first companies to market PSD to HTML conversions in 2005. At the peak of their success, they transitioned to an SEO company. In 2013, our relationship with a well-known agency resulted in a manual spam penalty.
Recovering from the penalty was a very painful process. There were two in-house marketing departments that hired several agencies to analyze over 2,500 linking domains. They spent a year and a half trying to remove the penalty, which included submitting numerous reconsideration requests that failed.
Since we finally had the penalty revoked, we wanted to share our experience with other companies, website owners, and SEOs that might be suffering from the same problem, and include some useful tactics for removing penalties.
It is also important to give credit to our outstanding consultant who helped us overcome the disaster.
