Please keep in mind:
When you set the minimum metrics like authority score (DR/Domain Rating) and ST (estimated monthly organic Search Traffic), these are just the minimum requirements.
Naturally, you will get a blend of many DR’s above the minimum limit, i.e. if you set the minimum authority score at ’30’ you still may get DR 40-70 links! But you still only pay the DR 30+ price if that is what we agree to in the beginning as your minimum metrics requirement (during the quoting process).
These are not cheap link farm sites that are going to get you penalized, but niche-related websites that get actual traffic from Google and you get to approve all of them before any links are built! So no surprises!
