I'm scratching my head trying to fathom out why my site took a big hit after Penguin. I have cleaned up some duplicate title tags and taken about 10 links down that I had to my main site from other sites I own (just in case) and I submitted a reconsideration request to Google and I have had a reply saying no manual penalty. What I want to know is does Google send out the same response to a reconsideration request or is it possible that they look at your site and give you a vague clue on what might be the problem.
Here is the response I got from Google. Is this the standard response or might there be a clue on why my site suffered a 50% drop in traffic? Any commenst appreciated.
"If you've experienced a change in ranking which you suspect may be more than a simple algorithm change, there are other things that you may want to investigate as possible causes, such as a major change to your site's content, content management system or server architecture. For example, a site may not rank well if your server stops serving pages to Googlebot or if you've changed the URLs for a large portion of your site's pages".
