If you want to make your website more accessible (and generaly more interoperable between browsers) then validating your website HTML and CSS at the W3C  is a good first step.

Edward Lewis AKA pageoneresults decided to test seo companies’ websites and call out those seo whose websites failed validation after reading Aaron Wall’s article about, essentially I thought, companies who touted validation as a necessary SEO service.

SEO Companies Validation Results

As you can see from Edward’s article, the Hobo SEO company site passed (although I stil think there’s big improvements that can be made to inner pages of our site to improve rendering and page load speed, interoperability and accessibility).

It is interesting just how few seo companies actually seem to consider basic validation important on their own sites considering it’s required by LAW in many countries for websites to meet basic accessibility requirements.

Never mind if it helps you move from rank no 143 to 142 in Google, in the UK, web managers have a legal responsibility to consider within the UK DDA where relevant to websites.

Note – It’s widely considered W3C technologies would be cited if a case ever got to court in the UK.

We've recently updated our comments policy and increased the number of comments a visitor has to make to get seo friendly links in comment signatures to reward long term readers and make it a bit harder for dofollow spammers ;) - I told you dofollow spamming wasn't a long term strategy....
