I haven't checked out the links you provided and have no experience with them, but I do have experience with other "Drive traffic to your site" services. I've paid some who promise thousands of visitors to your site, yet to find out later through our own tracking system that they weren't sending actual visitors to our sites.
In my experience, the most guaranteed results (yet can be pricey) is google adwords. Not saying the "best" results, but they have provided the most results.
I'd search forums and do alot of homework on a company before paying them for this. Get users' opinions. |
