Pop-up windows are those little windows that automatically pop up at
same time when you are trying enter or exit a web site. Many webmasters use pop up windows to display ads or subscription instructions to their ezine. Many marketers do not employ this strategy because they feel that it will annoy their visitors. But fact remains, pop-up windows do work. The benefits of using pop-up windows far outweigh negatives associated with them, but only if you use them properly!
There are many sites that use multiple pop up windows when someone clicks on to their web site. This is very annoying when five or six pop up windows open and most web surfers consider this a form of "spam." This will be sure to turn off any potential customers and kill your chances of repeat visitors.
If you are going to display a pop-up window, you should only display one window, either executed when a visitor enters your web site or when visitor exits. There are scripts available that will let you send a cookie to visitor's computer so that no matter how many times they enter or exit page that calls pop up window, thy will only ever receive one pop up.
When I write about cookies, I am not referring to Mr. Christie or Oreo cookies that people eat. For those of you that are new to Internet, a cookie is a small file that is sent to your computer from web site to either gather information about your surfing habits or to let web site know not to run a certain script (i.e. pop-up window, survey, etc...).
I suggest executing pop up window when visitors exit your web site because you do not want to hit them with to much information when they enter your web site.
