Can anyone find evidence from any case studies,from any source on recoveries using the disavow tool, not involving a manual penalty. ie purely algorithmic ?
Nearly three months, isn't it?
If I understand the way it works correctly, there will be no recovery stories yet, as far as Penguin 2 goes at least as the algo hasn't been re-run.
1. Remove as many links as possible, disavow remaining links. 2. Wait for those pages to be re-crawled. 3. Possibly see a further drop in rankings as links are taken out of the 'link graph'. 4. Wait for the Penguin algo to be re-run. 5. Penalty lifted/not lifted if site is deemed to have a clean enough profile. 6. Even if lifted, site probably won't recover to previous rankings as no longer benefitting from removed/disavowed links.
I'm guessing the algo will update every six months or so to serve as punishment to webmasters (and anyone searching for relevant but Penguinized pages/sites using Google).
