Through our handy Ask The Doctor service, we get a lot of e-mails asking us about HTML5′s effect on Search Engine Optimisation (SEO). While we can’t answer in great detail (Messrs Google, Yahoo, Bing, and their friends haven’t sent us in-depth details of their algorithms), we’ve rounded up some useful facts from Google, the world’s most dominant search engine.
The clinic is getting busy with more HTML5 ailments. This week, we’ll cover server-side validation, immutable images with
<canvas>, retrieving drawn objects from a
<canvas>, creating custom tags, the
role attribute, and the effects of
<hgroup> on SEO.
Last month we decided to pull together a post that covered some of the emails that were sent in through the contact page. Since the publication of the last post we have received a lot more questions regarding the HTML 5 spec and have decided that some of these warranted another post.
