thanks for the info
however on one of my customers sites he runs php nuke and it doesn't show up at all..
Also I cannot use prepend on some sites that run blogs, Any ideas?
once again thanks for the info...
I have the same problem. For some reason, some php scripts do not accept headers and footer ads. I think it has something to do with cookies. However, a pop-under, pop-up or floating ad will work fine.
You might want to go with a floating ad because...
1. You can have them "Fly in" on page load which catches the surfers attention.
2. You can use "Rich Media" like Flash which makes it more effective.
3. It's not apop-up. It's DHTML so they cannot be blocked by pop-up blockers.
4. You can have it set to automatically disappear after a certain amount of time. For example; If your ad is a 20 second flash movie, have it set to disappear after 25 seconds. Your clients will appreciate it because it does not interfere with their design and it's not permenant.
5. You can set it to only appear once per browser session. This will make your clients very happy and make your unique visitor stats very accurate.
6. You can place a small "x" which will close the floating ad down when clicked on.
ESPN and Yahoo use Floating Ads if you'd like to see an example.
