1) Do not use splash pages

Splash pages are the first pages you see when you arrive at a website. They normally have a very beautiful image with words like “welcome” or “click here to enter”. In fact, they are just that — pretty vases with no real purpose. Do not let your visitors have a reason to click on the “back” button! Give them the value of your site up front without the splash page.

2) Do not use excessive banner advertisements

Even the least net savvy people have trained themselves to ignore banner advertisements so you will be wasting valuable website real estate. Instead, provide more valueable content and weave relevant affiliate links into your content, and let your visitors feel that they want to buy instead of being pushed to buy.

3) Have a simple and clear navigation

You have to provide a simple and very straightforward 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. If your visitors don’t know how to navigate, they will leave your site.

4) Have a clear indication of where the user is

When visitors are deeply engrossed in browsing your site, you will want to make sure they know which part of the site they are in at that moment. That way, they will be able to browse relevant information or navigate to any section of the site easily. Don’t confuse your visitors because confusion means “abandon ship”!

5) Avoid using audio on your site

If your visitor is going to stay a long time at your site, reading your content, you will want to make sure they’re not annoyed by some audio looping on and on on your website. If you insist on adding audio, make sure they have some control over it — volume or muting controls would work fine.

Browser manufacturers have already started rolling out support for many of the new features even if they aren’t yet set in stone. Opera and Safari have been leading the way when it comes to CSS 3 features, but Firefox 3 packs in a few and 3.1 promises to bring Firefox alongside the others. Users of Internet Explorer are out of luck. Although, there’s no reason you can’t use some rounded corner properties solely for your Firefox/Opera/Safari visitors. IE will still render the backgrounds as usual, it just won’t understand the rounded corner bit.
