Hi!

I used PopUnder windows to promote websites.

The problem is that popunder windows become inefficient because 80% of the internet users use pop-up and popunder killers like GoobleBar and many-many others.

I am searching for new and efficient ways of promoting websites.

Thanks for your answer!

Nowaday, there are lots of pop under/up blocker software like yahoo toolbar, google toolbar. In addition, the browser like netscape, IE also have this function. Advertisers is hard to promote their sites through pop under/up program.

I suggest you can join banner advertising program. In our company, we have one program called Popinads.com. This kind of ads will not be blocked by pop under/up blocker software. This is the demo http://popinads.com/preview.php?type=publisher.
