Why Validate Your Pages?

There are many reasons to write valid HTML, XHTML, and CSS and to check for valid links. Here are some of them:

If you want your site listed on search engines (who doesn't?) then make sure that you have correct HTML. Many engines cannot properly catalog or index a site that has serious HTML errors. This can greatly reduce the amount of traffic your web site receives from search engines.
Properly written HTML will render better, render on more browsers, and render faster than HTML with errors. It's also more easily adapted to print and alternative browsing devices like mobile phones and handheld computers.
Properly written HTML is more likely to be "future-proof" (backward compatible with future standards and future web browsers).
Broken links can quickly drive visitors away. How many times have you been annoyed when you found a broken link?
Problems such as "ugly" pages caused by poor HTML constantly drive visitors away from web sites. Do you want your web site to be one that customers will leave because of poor quality?
If you think that your HTML is good the way it is and that you don't need to check it (as many people think), then let CSE HTML Validator check your HTML to prove that you're right. Chances are that you will be surprised and that your HTML will need to be fixed.
Browsers are becoming more standards compliant, and it is becoming increasingly necessary and important to write valid and standards compliant HTML. CSE HTML Validator will help alert you to HTML that is not standards compliant and that may cause viewing problems for visitors.
A WYSIWYG editor is no excuse for not producing good HTML. If a WYSIWYG editor does not produce good HTML, then it should not be used or its output should be fixed manually. Newer WYSIWYG editors are better but many still have problems writing correct HTML.
Having a site that uses dynamic pages is also no excuse for bad HTML. CSE HTML Validator lets you easily check the HTML output of your dynamic pages. If your dynamic pages are outputting HTML that is full of errors, then you need to fix them.
Writing error-free HTML is the best way to help ensure that pages render optimally in as many browsers as possible. This includes older browsers and browsers that are yet to be developed.
Write it right the first time and write it once. Write it wrong, and you may be writing it again later.

Internet Explorer Security Issues

Because of the long history of security issues with Internet Explorer, many computer experts and companies (including AI Internet Solutions) are recommending that people stop using it. This means that other browsers, like Firefox, Mozilla, Opera, and Netscape will be used more often. Therefore, your web pages should be built properly so that they can be viewed without problems on various browsers, and not just on Internet Explorer.

Netscape 6 and Above

Netscape 6, although buggy in its first release, uses a completely rewritten rendering engine. Therefore, tricks used to make HTML render as desired in Netscape v4.x will probably not work anymore. Furthermore, Netscape 6 is driving toward standards compliance, and proprietary elements like "layer" and "ilayer" are being dropped. So what can be done to make sure that your pages render properly in Netscape 6 and its successors?

The best way to ensure that your pages render properly in Netscape 6+ as well as in other browsers is to write valid HTML in the first place. Problems that visitors have when they view pages with Netscape 6+ may not be due to bugs in Netscape, but instead are likely to be due to bad HTML. We also believe that Netscape 6+ is less forgiving of bad HTML than other browsers, such as Internet Explorer.
