Review So I ordered my test post from Blackshield and although there was a few problems on the bloggers end causing delays, Blackshield managed to deliver the post on the domain I wanted. It is a DA 52 domain that gets 6600 organic traffic from Google each month. My advice to any potential buyer would be to inbox Blackshield and ask for any domains in your niche that he already has a relationship with as he has some excellent domains with great stats and offers a solid discount for these domains. I was about to purchase another guest post from Blackshield on a niche related domain but one of his competitors on here delivered a post on that same domain but charges three times more for the post than Blackshield was going to! It just goes to show that you can save a fair bit of money if you inbox the service provider and ask for any domains they have an existing relationship with.
