Hi ... yes, many are scamming, as Shanez20, but high end categories deliver, well. You might be astounded at what "major" sites buy visitors, by the millions. Try this
vendor, if you like. The high end, effective categories are on the right side, especially the last 2-3. Better yet, try advertising via AdBrite. Use full page ads and bid the minimum, which I think is $ .001. If your page is effective, AdBrite should convert. You can specify site categories and specific sites. Yes, you'll get lots of sites running your ad at $.001 per view. Hope this helps. Good luck. Do let us know what you decide and how it goes.
