My main site was getting 7,000+ uniques a day... Netting x,xxx a month. After penguin it dropped to 500 UVs and xx per month. I tried many methods. I deleted tags, related searches and even the side bar. Did not want anything repeating on the same page. Well let me tell you, that did not work. I de-optimized my site to the point where it was just top menu and the article below (no side bar). I thought this would help, well it didn't. 4 days ago I went crazy. I changed ALL my permalinks (It's a wordpress blog). I changed from SITENAME.com/date/postname to SITENAME.com/postname So every article I backlinked to is now a 404. (Thousands of backlinks I had with specific anchor keywords for each article are now dead.) Second thing I did: Every high PR site I owned I linked to my money site (just for the PR authority). All those sites (all 6 of them) had nothing to do with my money site niche... I just wanted the PR. Well I deleted those backlinks. Third thing. I reloaded the sitemap and re-submitted to google. And BAM !! Yesterday I went from 500 to 1200 UV's. Today I am up to 1700 and it looks like it will keep growing. I am not sure if the permalink change did it or the removal of the links that had nothing to do with the site. I really doubt that the links were the culprit as I xrumered the shit out of that site so it has thousands of others worthless backlinks. Or maybe google updated again? Not sure. Just wanted to share with you guys out there who are in the same boat as I am.
