Our website has been hit hard with penalties since last year. Traffic dips were at the same times as Panda and Penguin updates and only 30% left :( I never thought they would affect us, as we don’t do over optimize and create quality content. We receive lots of links from manufacturers of the widgets we cover, and we’re linked in signatures in forums of large companies, like the software giant from Redmond. We have not bought links, participated in link exchanges etc.
But users have added links to guides from us in signatures, some people link to use from all their pages. We also do support forums for some companies and they link from all their pages to a subforum we've created for them.
The site started in 1997, name was changed in 2010 with 301 redirects correctly setup. We have been an authority site, we have 500k forum members.
When I look at Webmastertools our incoming link profile looks like this:
Domain Links | Pages with Links
oursite 1.273.403 | 91.864
largecompany 4.221 | 19
whatarewidgetssite 14.143 | 3.903
famoussoftwarecompany 9.868 | 169
whatarewidgetssite 9.260 | 4.062
rssaggregator 8.596 | 7
knowncommunitysite 7.945 | 174
crapsite 7.229 | 1
gallerysite 6.735 | 1.025
softwarecompany 6.652 | 1
redmond 4.612 | 44
productpagessite 3.221 | 164
personalrssaggretorsite 2.980 | 1
largeforum 2.470 | 19
largeforum 2.228 | 270
largeforum 2.100 | 51
largeforum 1.989 | 221
domaininfo 1.636 | 593
etc.
etc.
whatarewidgets sites -> I mean sites that explain terms and link to e.g. our guides.
domaininfo -> a site that gives domain stats and that kind of stuff
What I've done so far I've asked the software companies to add rel=nofollow to the links to us on all their pages
Disavowed the crapsite mentioned
I guess I should also try to get the RSS aggregators removed (at least the personal one?) , the gallerysite, the productpages site (really bad site) and maybe the domaininfo site?
I would love to hear what your advice would be...
