Earlier this year James Weiner and Ben Welby wrote about the browsers and devices that we are supporting on GOV.UK. We made these decisions using browser/device data from various sources including Directgov, BusinessLink, central government departments and several other big sites.
Now that GOV.UK has been getting real traffic for a while, we are starting to gather our own usage data. I wanted to share quick snapshot of the data so far. The figures we've collected aren't much different from what we expected before launch.
All of this data is from 11th November to 11th December 2012.
As expected, Internet Explorer is the top browser with around 42% of the traffic. IE9 is the most used version (22.4%) followed by Chrome (20.1%), IE8 (15.7%), Safari on iOS devices (8.7%) and Firefox 16 (6.4%).
In January around 3% of visitors to Directgov used IE6, this has dropped to just over 1% on GOV.UK.
This data looks at all of GOV.UK. If we extract out just the Inside Gov part of the site, the figures change quite a bit, reflecting the change in audience.
Internet Explorer is still the top browser but gets a much higher percentage of visits - around 53%. IE8 (not IE9) is the most used version (24.9%) followed by IE9 (19.7%), Chrome (18.2%), IE7 (6.5%), Firefox 16 (6.2%) and Safari on iOS devices (5.8%).
IE6 use is around 1.6% for Inside Gov traffic.
As we know this data is valuable to many people, including those outside government, we are planning to share these figures regularly, as we do with the GOV.UK Performance Dashboard. More on that soon.
