I can also report a semi-recovery.
Our site go hacked as it was on an insecure plesk (lots of those still about) at the same time as a gradual decline for our main keywords. We spent 5 years in top 3 but then declined with our main keyword from first to down in the hundreds, due to a penguin I believe.
I installed a new website with as many redirects in htaccess for our keywords that i could remember.
(As an aside I have many sites that seem to die after 5 years exactly, link juice lifetime probably)
Because of the keywords that were affected I first suspected keyword stuffing on pour main keyword, so I brought the ratio down. (I hadn't changed the ratio for about 7 years). This brought it back to about page 4 so maybe i was correct.
About 100 high quality posts for about 5 keywords resulted a jump of 2 to 4 places.
I have never used a disavow tool but i did remove/move a few PDF's that were being linked to from other sites i knew nothing about.
Also deleted a very similar structured sister site with no activity but a few links to our main site and removed it from WT.
The Penguin rollout on the 4th jumped them another 4-5 places or the keywords I have concentrated on.
I have noticed a drop in one of our competitors, who only use good quality links and practices, but a little too often in my opinion.
We are now at the bottom of page 1 from nowhere in 6 months and i am STILL getting reports in WT about pages that were on the old site but they are much less since Oct 4th suddenly.
Traffic has also jumped by about 15%. Now only Brands get the first few places on page 1 due to masses of sitewide links I assume, the bottom half is as good as can be expected these days.
