Re: What is your opinion about pop-under exchanges?

Pop-under exchanges give you a small fragment of code to insert into your web pages. When a visitor enters your site, a window pops up underneath the browser with a member's website loaded in it.

The better pop-under exchanges use a cookie to make sure that only one pop-under is displayed for each unique visitor to your site.

In exchange for allowing your site to spawn the pop-under, your site will be displayed in a similar pop-under on another member's site.

An exchange ratio of 3:2 is common, which means that for every 3 times that your site spawns a pop-under displaying another site, your site will be displayed twice. The other "lost" pop-up is sold as advertising by the pop-under exchange.
