This PHP script allows you to create and use an unlimited number of ad trackers (as well as website visitor counters and split-tests for sales letters and squeeze pages). Each ad tracker will direct traffic to a destination URL ("landing page") of your choice, and keep track of the time/date, IP address, and other details of users who clicked on your advert.
Using ad trackers allows you to measure which of your advertising and marketing campaigns are generating traffic and which are not. This allows you to focus your marketing efforts on campaigns that work - so you do not waste time or money placing ads on ineffective websites and ezines.
As well as recording the amount of traffic, the ad trackers also record the IP address and other details of each user who clicks on your ad. This makes it easy to detect "duplicate clicks", such as a competitor repeatedly click on your ad, or an affiliate trying click fraud - two things which you will surely want to know about if placing pay per click ads on search engines or elsewhere!
