These little "tools" have to be the most annoying addition to any website. They basic send the message that you do not understand the meaning of the word no. If you have a website dedicated to some affliate marketing program, odds are when someone clicks the "x" or tries to navigate away from your page, it is not an accident. Is there some reason not to gracefully allow them to leave?
Perhaps you think forcing them to hang around makes them more receptive to something they are not interested in in the first place? And there are varying levels of these annoying little detaining mechanisms. Luckily with the first level you just click OK and get released to go along on your way. The mega-annoying ones are the ones that try to engage you in conversation. they open up a chat box that takes you to a standard per-set automated response system. Of course they are pre-programmed with responses. You will notice no matter what you tell it, it always comes up with the same responses.
But either way I view them as an imposition. There are laws about unlawfully detaining people. Too bad they can't be applied to the internet to prevent these so called marketing techniques that have no value except to annoy your prospects. There are some cases in which these exit pop ups can be helpful. I personally don't think selling and recruiting qualify. In my opinion using these things to market your programs and opportunities is misuse of technology. But I'm sure if I were to take the time to look, I'd find it somewhere among the guru driven gibberish that this is effective in increasing your sales conversions.
I find myself wondering when people will realize that 90% of this guru drivel only accomplishes one thing.
Annoying your prosepects!
