Welcome to the Q&A Forum

In February I had an Seo audit done on my site. I got advice that my link profile at the time was very strong and natural. They gave me some advice that I could improve my anchor text of my links with a much more friendly keyword anchor text. Example I have game site and instead of using the name of my site I was told to change this to Strategy war games or Online war game etc.  I went through my google link profile and messaged several webmasters and had my anchors changed to this. I also changed a lot of my links to this more keyword rich anchors. May 22nd I had a drop in rankings of about 10 spots across the board and google traffic came to a trickle. I can only assume these two go hand in hand. Should I go back and change my links to my website name and stay away from that keyword rich anchor texts ? Can I fix this ? I am almost 100% positive this is  a Penguin penalty since I looked at my analytics and it is obvious after May 22nd something changed. Can I fix this ?
