How to place PopUp ads to maintain revenue level and reduce the "annoyances"

PART I

[PART I] [PART II]

Most affiliate programs that offer popup or popunder ad formats will only count the very first popup ad to the same visitor as valid.  If you have a popup or a popunder in EVERY single one of your pages, then if this visitor surfs through five pages, then he or she will get FIVE popups.  As we all know, it's annoying enough to get one popup and if you get a bunch more popping out continuously, chances are you will never return to that website again.  

Other than hurting your loyal, returning visitors, these continuous popups and popunders also kill the professional look of your site.  If you offer trustworthy news content, tons of popups will make your readers lose their confidence in your news.   Not to say, any additional multiple popups other than the very first one do not make you ANY revenues at all. 

BUT, you may ask, "There's no way to predict which page of my site the visitor will enter from, so there's no way to predict which page is the right page to place the popup ad code on?"

You're right, there's no way to track which page the visitor will enter in from, but what you can track is how many pages your visitor have surfed!  You can track this using a session variable that works as a counter and increases every time your visitor surfs a page.   Unfortunately, you have to use either php, asp or coldfusion (cfm) scripts for your site in order to implement this method.

For php and asp, you want to include the session variable code in the so called "header.php" or "header.asp" page of your site.  This code should appear in all sites.
