“In general, our crawlers are used to not being able to parse all HTML markup - be it from broken HTML, embedded XML content or from the new HTML5 tags. Our general strategy is to wait to see how content is marked up on the web in practice and to adapt to that. If we find that more and more content uses HTML5 markup, that this markup can give us additional information, and that it doesn't cause problems if webmasters incorrectly use it (which is always a problem in the beginning), then over time we'll attempt to work that into our algorithms. With that in mind, I definitely wouldn't want to stand in the way of your implementing parts of your site with HTML5, but I also wouldn't expect to see special treatment of your content due to the HTML5 markup at the moment. HTML5 is still very much a work in progress, so it's great to see bleeding-edge sites making use of the new possibilities”
“In general, we work hard to understand as much of the web as possible, but I have a feeling that HTML5 markup is not yet as widely in use (and in use correctly) that it would make sense for us to use it as a means of understanding content better. As HTML5 gains in popularity and as we recognize specific markup elements that provide value to our indexing system, this is likely to change, but at the moment I would not assume that you would have an advantage by using HTML5 instead of older variants…..”
“Personally, I would recommend using HTML5 where you think that it already makes sense, perhaps reverting to HTML4 if you can determine that the browser won’t support the elements of HTML5 that you use properly. While this will not result in an advantage for your content in our search results, it generally wouldn’t be disadvantageous either.” |
