It’s obvious that HTML5 is being embraced to a certain extent, but how many Web sites have really converted? There’s no way to get an exact number, but we can get a good idea of the progress being made by taking a look at the most popular sites on the Web.

Number of Web sites using HTML5 as of September, 2011.

In order to get a picture of how many sites are making the moving, I decided to start a quarterly report called the HTML Census take a look at the 100 most trafficked sites for September, as ranked by Alexa. To get a broader view, I eliminated sites that were listed multiple times under various domain extensions and included the next domain on the list. For example, Google.com is included in this data, but Google.co.uk and Google.com.mx have been excluded since they all use the same code.

Analysis showed that 34% of the sites on Alexa’s Top-100 list for September 2011 were using HTML5 to structure their homepages. Let’s first take a moment to look at the makeup of the Web sites that are among the 100 most visited on the internet.

  • At 17%, Social Media sites held more spots than any other industry.
  • Not far behind were Technology mainstays, at 13% – these are mainly sites that offer software downloads and support, like Mozilla.org, Microsoft.com and QQ.com.
  • 13% of the listings were held by Search Engines.
  • Adult, Entertainment, and News Web sites each came in at 7% of the sites in the top 100.
  • The rest is comprised of sites from Online Storage, Shopping and other industries.

What I found, as you’ve probably already seen in the image above, is that approximately one-third of the Internet’s Top-100 Web sites are currently using HTML5; that portion comprised largely of Social Media and Search Engine sites.

The full 4-page report with data is now available below in PDF format for download. If you can think of any ways in which this report can be improved for next quarter, please contact us or leave a comment!

 

Does this number surprise you? If so, would you have expected it to be higher, or lower?

    This is some really interesting stuff, it’s good to see that so many sites are making the switch to HTML5. I hadn’t thought about it but it does seem to make sense that Social Networks and Search Engines are leading the way since they are more in touch with the development community.

    Awesome post, thanks for taking the time to put this together.

    Bookmarked!

    Interesting, thanks. A couple of ideas for future reports. It would be really great to see -

    1) Which HTML5 features are being used. You would have to dig a bit deeper than the doctype to find audio, video, appcache etc

    2) What proportion have mobile specific optimisations. Maybe not necessarily HTML5, but likely a strong correlation. You could search for a few common meta tags used for mobile webapps. eg
    and use an iphone user agent, to allow redirect if the site uses.

    Just some ideas.

    You can compare it also with past year charts. As, I am new to HTML, how can I get exact figure. It is just like comparison of web browsers, and person finally knowing that Internet Explorer is most popular browser. But if he is provided with previous year comparison also, he can easily derive conclusion.
