Although there has been a great deal of controversy over the use of pop-up windows, the fact remains; pop-up windows are highly effective. The latest pop-window trend to hit the Internet is the pop-under window. Pop-under windows are less intrusive than the pop-up windows and are believed to be even more effective. If you spend any time surfing the Internet, then you've probably encountered several examples of pop-under windows. A prime example is X10.com's pop-under ads for their wireless video cameras. X10's pop-under ads were popping up on prime media sites like MSN, the N.Y. Times and Alta Vista. Their main advertising objective was to increase their website traffic. And, they have done so with a high rate of success. Unlike pop-up windows that load over your web page, pop-under windows quietly load under your web page. Your visitors probably won't even see the pop-under window until they're finished at your site and close the window. The effectiveness of pop-under windows most likely stems from the timing. When your visitor first enters your site, their mind is on what lead them to your site to begin with. Pop-up windows will most likely cause a higher percentage of your visitors to instantly close your window before viewing its content. That's what makes pop-under windows more effective -- your visitor is through visiting your site and their mind is clearer. They will be much more likely to take the time to look at your offer when they don't have another objective on their mind. Pop-windows provide Internet marketers with an effective alternative to the declining effectiveness of banner ads. However, studies have shown that most Internet users find these windows very intrusive. Issah L http://medicaltestingsupplies.com
