This shows in my google webmaster tools. Anyone else experienced anything like this? What are you doing to get back your rankings? In October my google rankings were similar but from then onwards my traffic multiplied 3 to 4 times and now after 15 Dec 2012 it seems google has put my site back on the place where it was in October. I just want to know what's going on.
I was hit a few days later. Search engine traffic is down to almost nothing. The only thing I could find was this: http://www.business2community.com/seo/matching-google-algorithm-to-your-traffic-loss-0363923 I haven't tried it yet, but I would have to think the steps they're pointing out couldn't hurt. I have to do to something, but unsure how to fix this.
If you have wordpress or others make sure there is not a plugin that is malfunctioning or needs updating. If you have a cache check that. If not that its more then likely due to a search engine algorithm change
Anchor text diversity could be one of many reasons for your drop in SE rankings. If you're main keywords make up over 30% of your overall anchors, then you can expect to have have been penalized by Google. WebDev
