Price is $3 per one unlinked website, no matter how many unnatural backlinks to your website it had, payment is required upong getting the bad backlinks down.
After we email everyone you are provided a spreadsheet with all details to verify what and how has been done, then pay the above price, and receive a file for the disavow tool, then you upload it to the disavow tool in your WMT account and submit a reconsideration request, providing them a spreadsheet with details about who and how was contacted, and in three weeks, once you see the result - penalty lifted, I additionally receive a bonus of $50.
To get an idea of the final cost please be advised that normally 20-40% of all websites that need to be unlinked and that we contact actually unlink and you pay for them, the rest just ignore our requests and therefore get into the disavow file.
From you we will need the following: 1) link-removals[at]yourdomain or similar mailbox; 2) list of unnatural backlinks that need to be removed.
Risks. There is a possibility that first reconsideration request does not succeed. This may happen if one or more unnaturally linked sites are temporary down or inaccessible for crawlers in the moment your links report was generated. If that happens you can easily verify it as in case of reconsideration request rejection google provides samples of sites they still do not like, and every time that happened those links were not in the clients' first reports.
