SEO Tip #102: Is HTML Validation Necessary For Ranking?

  • SumoMe

Matt Cutts: Today we have a guest to answer today’s question. Danny how would you answer that question?

Danny: Well a lot of websites can have invalid code but render just fine because modern browsers do a good job dealing with bad code. And so it’s not that the code has to be absolutely perfect but whether or not the page is going to render well for the user in general.

It makes sense to still list these websites. It makes sense not to be that specific and plus people make a lot of mistakes because they are using different HTML editors or maybe they are doing some hand coding and they are little tiny things that aren’t going to have that big of an impact.

If you were trying to be very, very specific I suspect and Google would certainly know but you’d have a lot of websites that would be left out for no good reason because they would still be validating just perfectly fine.

Matt: And you were even joking a little bit about

Danny: I did and for example in this question there is a grammatical error in it. I can understand what the question is about perfectly well but if I were going to invalidate even taking questions based on them being perfectly grammatically correct then it would be lost.

And so in that case if you will Google can understand and deal with pages that are perfectly grammatically correct and perfectly HTML correct and it can also understand when you are being a little more casual because basically it understands what the page is about.

Matt:So Danny nailed that. I don’t really have much to add other than usually if a page doesn’t validate it still can look perfectly fine in a browser, which is exactly what you said at the very beginning. So great question and thanks for sending it in.
