Welcome to the Q&A Forum

Hi Jason, Most of time these days (but not always) when you experience large differences in ranking between Google and Bing, it's often because of backlinks. Taking a quick look at your backlink profile in OSE, I'd venture to guess either a Penguin action or "unnatural links" penalty is a good candidate. Try the Panguin tool to see if your drop in traffic corresponds with a known Penguin update (requires a Google Analytics account) Hint: when you've got a link on a page like this, you might be in trouble: http://www.playcasinoguide.com/links/Sports.html Here's a conversation I had with another webmaster facing a similar problem: "You probably want to try to save the site. I'd start by doing a complete site audit for low quality links. Our friend Paddy Moogan wrote a great post about this: http://www.stateofsearch.com/step-by-step-guide-finding-low-quality-links/ The big question is if you need to file a reconsideration request. Did you receive any messages in Google Webmaster Tools? If not, you may want to file a request just to see Google's response. Often they will verify this way if a site has received a manual penalty or not. Also a good post by Ryan Kent on identifying penalties: http://www.seomoz.org/blog/identifying-link-penalties-in-2012 Understand that Google's reconsideration process can be a several month process. It's best to try to remove as many links as you can - (and show a serious effort to do so) and use the disavow tool as a measure of last resort. Finally, and I can't stress this enough, the number one thing that helps after you've cleaned up bad links, is building good links. Keep us up to date on your progress. With some work and due diligence, your site may come out of this fine." Best of luck!

Thanks for the response Cyrus.
