I have "the honor" to be guinea pig for Google updates.
I'm almost untouched by the big algo changes! In the last year I had problems ONLY on "strange google updates"...
No manual penalty, no reconsideration req.
So what I did is to get all the links reported in WebmasterTools and Majestic SEO by hand and check them until I've reached 100 links to my site, this was very time consuming.
A lot of sites with RSS from me, a lot of spam, a lot of parked domains, a lot of sites with search results (+links to my site), a lot of clones and stupid redirects (I have the classic iframe protection js).
It's a "mature" site (2002) and the links where majority OLD links. I belive I've blocked 75% of the sites :(
I've trashed (disavow file):
- NO PR sites
- clone sites
- sites with no results in google for command mysitename site:xxxx
- spam search sites (with results from google inside)
- parked domains
- not working domains
- sites with site-wide links to my url
- a lot of boards that where using my RSS in order to create threads...
- a lot of wiki type sites
- a lot of .gov hacked sites
- a lot of Chinese boards
- a lot of directories
- "shady" social networks
I found 200+ .info domains with the same favicon and same content: link directory.
What I ca see is that I could find very few 2011+ links!
I think that google has just created a new problem... with this link paranoia!
