You should know first that majority of web pages are done using HTML. Like every language, HTML utilizes its own set of syntax and grammar and every document written with the use of HTML should follow rules accordingly. However, since HTML constantly undergoes change, it has become sort of a complicated issue. People now easily commit HTML errors and when the HTML code produced doesn’t follow the set of official rules, it becomes an invalid HTML code.
Search engines need to parse your web site’s HTML code in order to find a relevant content. If for instance, your HTML code have errors, there is possibility that search engines will not be able to find content on your web page. And in the process, it short circuits your efforts in optimization. Those dynamically generated links or URL’s that finish in numbers or question mark are similarly overlooked by search engine robots. If this happens, there is a need to “re-write” rules on the usable .htaccess file so they could be listed in the SERPs.
The crawler programs of search engines normally obey HTML standards. This means that they can index your site only if it follows the sanctioned HTML standard. If there’s an error in the site’s web page code, search engine spiders might halt crawling your site, losing what they’ve accumulated so far. Even if majority of search engines can let go of small errors, a “tick” or even one missing bracket can be a major problem.
A valid markup makes sure that spiders notice the web site as you intended. Missing or open tags, broken markup can produce ambiguous intentions on the part of the spiders. If your page is valid, you can be certain that any good spider is able to point out your wants and translate the page accurately.
