As everybody knows, BlastBank offer the opportunity to extend demo if we do a review.
Ok, this is my review. But honestly, what I am going to say it's true.
I have benefit from one blast to one site. It was not appearing in results, and after one week, has jumped to page 2 regarding my target keyword (high competition). I can't believe it!!
The system is really simple. You only have to get your urls, and that's all. It's easy, not complicated, and fully automated.
I haven't test DFB, but is more expensive, and I'm not earning so much moeny with my sites (for the moment). BlastBank offers a nice service and cheaper.
Also thank you for solving the issue with the demos so fast, and let me know by email. Really appreciated. Seems you care about your customers.
