Popunders are no longer technically possible for the vast majority of browsers used today. My advice is to forget about popunders and popups entirely.

There are lots of "web traffic" companies using popunders to generate traffic for online advertisers, and I must say that these traffic blasting companies are absolutely useless and a waste of business owners' money.

Generate traffic the right way. Build valuable content, join online communities, oneway link building, press releases, etc.
