HTML Validation

WorldWideWeb Consortium -
Queensland SEO proudly supports the WorldWideWeb Consortium


Why validate your website’s HTML coding?

There are many reasons and benefits to having an optimised website with 100% valid HTML coding such as compatibility across multiple browsers to displaying correctly for mobile devices but did you know having valid HTML coding for your website can provide subtle benefits to your website's SEO rankings?

Valid HTML coding increases your site's credibility with the search engines and enables search engine spiders to more efficiently 'crawl' your website for indexing in search results. Valid HTML coding also ensures your website will be displayed correctly for any future changes to browsers or mobile devices that may potentially impact a site that has an invalid HTML coding structure.

There are currently no known penalties in place for invalid HTML coding so at this stage, your website will not be penalised for having invalid HTML code however this may change in the not too distant future as search engines place more emphasis upon valid coding structures and compatibility issues.
