1. Make your website as messy as possible
Nothing makes visitors leave faster than a cluttered site that is difficult to navigate around. So if you want people to flee their site like a ravenous wolf, then make sure you put all that trash can on the home page. Then click on the links with the rest of the site difficult to find. Make sure you have lots and lots of images, forms, banners and pop-ups as well. All relevant information should be well hidden, and the main focus must appear that many programs you want visitors to sign up. That should keep any pesky visitors always return.
2. Never update your website
If someone visits your web site today and then come back six months from now should see the same information. Nothing should be updated. This lets them know that you care nothing about the website and they have nothing new to offer. The next time you see an ad for your site that does not even bother to visit. Very good!
