We launched a HTML 5 Website last year in an attempt to judge, if there was any SEO benefits from using the cleaner, robot friendly HTML5 Code.
Unfortunately, it seems not, our platform? Website Design Chesterfield
Website design chesterfield has had some great results, but still only as good as, if not a little worse than our Web Design Mansfield site.
So, whilst HTML5 may provide cleaner code – it does not seem to increase search engine rankings.
