This is a service that's supposed to get your backlinks indexed. I was with the $30 plan for 2 months, ran 3000 unindexed links with them TWICE. At the end of the second month i got 10% indexation rate. So low, that they very well might be indexed on their own as well. The owner denies refund, they even tried to bulls*it me that the actual indexed links are more, but Scrapebox index checker doesn't lie. So, you just know in case you are wondering if it's worth it.
