Kosta's service is my go to for outreach link building.

I have probably done close to 6 figures in orders with him personally and have recommended him to hundreds of my most important customers.

Because I have over 1,000 websites and constantly run tests, Kosta took my feedback and data and implemented it into his service to make it the most powerful of its kind out there, and only increasing in power as time goes on because of the things he is doing behind the scenes; which I can't talk about ?

This is one of my biggest secret weapons for SEO today.
