About 1 week ago, I noticed that my site description I had entered in the All-in-One SEO plugin for "OP" had a typo. I went back into Wordpress to correct the typo.
The next day, I went to check on my site ranking and noticed it was penalized. Both "MP" and "OP" are no longer in the top 1000 search results for either keywords (oddly enough, a third page on the site ranks on the 10th page or so for the secondary keyword).
It's been a week and I haven't seen any change. I've still been steadily building backlinks. I also submitted my site for reconsideration using webmaster tools. Do I just wait it out? Should I stop sending backlinks using my keywords as anchor text? Please help! If there's any other info you need, I'll be glad to help. Thanks!
