I have been using QGP for more than a year. I can not be more pleased with the high quality of the posts and how these posts rank my niche clients. It is the best guest posting service in the industry. Kosta and his staff provide outstanding customer service and get back to you very quickly if you email them.

I only used Kosta services for guest posting for my clients, and I highly recommend QGP. I have not found better guest posting service and high-quality posts anywhere!
