Hello,
I've succesfully completed multiple projects simmilar to this, (check feedback), and I'm sure that i can do it yet again.
I have a tehnique that has proven results, i'll look at multiple metrics such as:
- Page PR
- domain PR
- DA - PA
- geotarget
After this step i will go on all the links and determin if the content used is spammy (unreadable) if it is, then i'll disavow the link. Contextual links, these are the most powerfull,if sone right on website that are related to yours. Articles directories, most of them are deinxed by google and they bring a penalty with them when used, so Web directories.
The links from WMT can be of real help because they will show me how many google sees and what density the anchor texts are I'll will get ~98% of all the links using premium tools like moz, majestic, cognitiveSEO, ahrefs and others.
We can talk more here by ma-il or over sk-y-pe.
Best regards,
Cosmin.
