My rankings and traffic suddenly went down about 50% around the end of Feb 2013.
I never received any warnings in webmaster tools (and as far as I know never did anything even vaguely black hat) but thought it might be a penalty since the drop was so steep and as far as I know there were no major algo updates at the time.
I sent a reconsideration request expecting to receive an answer that I have no manual penalty. Instead, I received the following email:
We received a request from a site owner to reconsider how we index the following site: http://www.sitename.com/.
We've now reviewed your site. When we review a site, we check to see if it's in violation of our Webmaster Guidelines. If we don't find any problems, we'll reconsider our indexing of your site. If your site still doesn't appear in our search results, check our Help
There have been no changes in my rankings.
Does this reply mean that I have/had a manual penalty?
