Test all of your links to be sure they are working properly, and check them periodically to make certain they are still active.

When you create a site and view it on your browser, be aware that it will probably look different on other browsers. In some cases, features might even be incompatible with some browsers. You want to make sure that your site looks good to everyone. Check all your pages on the AnyBrowser web site, which will display your pages as they will look on several common browsers.
