I have an advertiser who's getting 400 to 600 clicks a day from his ad on my site, but says he isn't getting any sales. I'd like to be able to know if any of the people who click on his ad go through his checkout.
I'm thinking that the best and simplest way would be to set a cookie on my site, and then have his thank-you page either open a 5x5 pixel browser window on my domain or send an email to me if the cookie is present.
Right now I have his ad opening a 5x5 pixel browser window that stays open for 12 seconds after the person clicks. I use this to track clicks. I'm thinking that this little page would be the place to set the cookie.
Is there a script that would do something like this that you're aware of, or do you know of somewhere I can find similar script?
Thanks for any replies.
