Complying with web standards can give your web pages greater visibility in web searches. The structural information present in compliant documents makes it easy for search engines to access and evaluate the information in those documents, and they get indexed more accurately.
Because use of web standards makes it easier for server-side as well as client-side software to understand the structure of your document, adding a search engine to your own site becomes easier and gives better results.
Standards are written so that old browsers will still understand the basic structure of your documents. Even if they can’t understand the newest and coolest additions to the standards, they’ll be able to display the content of your site. The same, of course, applies to robots – systems that collect information from your site on behalf of search engines and other indexers.
