Top 50 Websites – Disappointing Validation Report

I found out today that my web site did not validate as valid (x)html markup (I had mistakently left out a closing “a” tag). I fixed the issue and am now validating properly. I then started to get curious about how many other bigger websites fail in validation. I went over to the Alexa Global Top Sites list and took notes on how many of the top 50 sites validate. Granted Google dominates a large portion of this list with their sites for specific countries, however I noticed that different errors were presenting themselves on different sites, so I just played along. So, how were the results? Extremely disappointing! Only five out of the top fifty site’s home pages were valid html or valid xhtml (that is just 10%). Sina, Imageshack, and were not even able to report how many errors there were to complete the test as some of the characters used were not even found in their specified text encoding. The sites that passed are MSN, Wikipedia, Skyrocket, Yandex, and Craigslist.

    @Yandex fans. A lot of Yandex fans here. I guess I am a fan of Wikipedia, but I will be looking into Skyrocket in the future.

    I think this helps show how meaningless validation is. It’s a programmer’s utopian ideal, but doesn’t really matter much in the real world. It certainly doesn’t affect site traffic.

    Try thinking about this from a bandwidth perspective. From Google’s position, saving a couple of bytes on each page view they serve far outweighs the benefits (if any) of XHTML validation. Millions of hits a day * a line or two of doctype will add up very quickly.

    Our site use to validate but we added a youtube video and now it has 5 erors. I can get rid of it using frames but won’t like the look. :(

    So how do I submit to Yandex? Someone told me once I could make a page in with the title in russian and them submit it and soon after it would get spider but I can’t read the language on the site. Any adeas?

    Well, we finally got the page to validate and a week later, the PR icon on IE jumped to PR2. We don’t really believe in that little gadget bu it was sure nice to see. :)

    Still would like to know how submit to Yandex.

    @Dom: I’m sorry but that is just dumb.

    I think it would be smart to make your huge website 100% compatible with screen readers and the like for disabled people, instead of trying to save a few bytes here and there. I highly doubt that’s the reason they haven’t bothered.

    Hey absolutely interesting, bonus for this information. Could I replicate this post on my site?

  17. Comment by 411 New York on August 18, 2009

    Can anyone teach us (free or paid) how to submit to Yandex?
