I signed up with $25.00 credit on the ZeroPaid site, and I selected Gadgets as my target category. ZeroPaid was the second most popular site available (after DP) so I thought I'd get quite a bit of traffic. However, although I have a 75% chance of my ad being displayed, I get fewer than 10 hits per day. The moment I change to a sitewide banner, I'm seeing my ad being displayed every few seconds. I think that I could have been better informed about where the traffic was going to within the site categories, because it's going to take years to use all my credit and get the impressions at this rate in my desired category.
Well the traffic stats aren't broken down by individual categories (imagine how confusing it would be if it was). It would be impossible to do something like list traffic for each individual area (for example this site the areas are broken down by forums and sub-domains). The traffic stats are 100% real though since the site owner can't enter traffic amounts. The traffic numbers shown are the *actual* traffic numbers our system sees and only includes pages that Digital Point Ads are served on.
also one more thing, when my advert is displayed, it's displayed like this.. is that allowed? I can only see less than half the ad, lol..
