Many of the major online advertising networks now also offer pop ups and pop unders. These alternatives pay more than traditional 468x60 banner ads - usually between US$2 - $4 CPM, but weigh your decision in using pop up ads carefully.   Pop ups are not the best way to make friends on the Internet. I know that I'm not the happiest camper when landing on a web site only to have my screen littered with a seemingly endless array of pop up windows!

Make Money with PopUp and PopUnder Ads

What are popups and popunders?

Popups and popunders are small windows that are generated by a web page when it is opened or closed. They come in many different shapes and sizes, typically in a scaled-down browser window with only the Close, Minimize and Maximize commands.

The basic differences between popups and popunders

Popups as the name implies, “pop up” on top of the web page you are viewing. Popunders are less obtrusive than popups as they open behind the web page you are viewing.

How effective are popups and popunders?

Making money through popups and popunders is easy. A lot of visitors on the Internet don’t like these types of ads though, so be prepared to take some flak if you do indeed decide to run them.

Generally when webmasters run popup ads or popunder ads, it is because they cannot be approved for Adsense. For example, a site selling guns, or a site that gives free MP3 ring tones. When a user goes to download a ring tone you want a popup ad so you might make more CPC that way, because users on these kind of sites tend to click ads little.

On sites where you have a low CPC, like webmaster resource sites, any type of download site, mp3 site, etc. Popups and popunders persist on sites like these.
