1. Do not use splash pages
A landing page is the first page you see when you open a website. They usually have a nice picture with words like "welcome" or "click here to enter." But it's just a text without a destination. Don't let your visitors have a reason to click the "back" button!
2. Do not use excessive banner advertisements
Even the least internet-savvy people have trained themselves to ignore banner ads so that you will be wasting valuable website real estate.
3. Avoid using audio on your site
If your visitors stay on your site for a long time, reading your content, you will want to ensure that they are not disturbed by audio loops on your website.
4. Have a clear indication of where the user is
When visitors are engrossed in browsing your site, you want to ensure they know what part of the site they are at. Easily. Don't confuse your visitors because confusion means "abandoning ship"!
5. Have a simple navigation
You must provide a simple navigation menu so that even a young child will know how to use it. Stay away from complicated Flash-based menus or multi-tiered dropdown menus.
