I manage several client projects with large budgets (B2B) and want to leave my review. As for the drawbacks: the service does not allow purchasing links in large quantities, regardless of the project settings, the purchasing process is slow; there is no option to set filters for selecting donors; I cannot place links on the sites I am interested in. Now for the positives: the support team is always available; they help with keyword selection; they provide good guarantees on links; the quality of donors is satisfactory in most cases. Overall, the service is more suitable for beginners. For those looking for more flexible project settings, this is not the place.
