Removing the external link icon from GOV.UK

We recently removed the external link icon from GOV.UK. That’s the icon that looks like this:

External link icon

Here it is on a page on GOV.UK:

We’d assumed that there was a clear need for the external link icon, but in 4 years we’ve seen no evidence that backs this up, so we're going to stop using it.

The pull request making the change contains a full discussion of why we’ve decided to do this, but I thought I’d summarise some of the reasons for our decision here.

You don’t always need to tell people about external links

There are some cases where you might want to warn users about external links in advance (for example if they’re in the middle of a task), but there’s no need to tell them every time.

The icon is obscure and ambiguous

The icon is not widely recognised and is often confused with the ‘opens in a new window’ icon:


Some websites actually use it to mean this, so it’s not an effective way of telling people that a link goes to another website.

Words are more effective

If your users do need to know in advance that a link goes to another website, it’s more effective to do this with words.

You can do this in the link text itself, or if you have a collection of links you might want to do this in the immediately preceding text to avoid duplication.

Next steps

We’ve removed the icon from the information pages on GOV.UK. As other teams in government update to the latest version of the GOV.UK Frontend Toolkit the icon will start to disappear from service pages too.

    You mention that you saw no evidence that people found it useful... can you elaborate on that? I would be really interested to know more about how a government team makes these kinds of decisions. Did you do user testing or some kind of data-driven approach? Did you consider a/b testing the removal and see if it affected how often links were clicked? Thanks!

      Hi Andy,

      We considered A/B testing, but it wasn’t clear how a change in the rate of clicks should be interpreted. If the rate went up, would that be a good or bad thing?

      With low level changes like this the evidence comes from multiple sources and there’s a certain amount of judgement involved.

      We drew on the experience of the design and research communities in government and asked them if they’d ever observed users making use of the icon, which they hadn’t.

      This gave us the confidence we needed to make the change, but we’ll continue to check in with GOV.UK teams to make sure it’s not causing problems for their users.

    Hi. As far as I know, the original intention of these icons was, in line with accessibility guidance at the time, to let users of screen magnifiers know that a link would open open in a new window (whether on the same site or not), because not knowing this was considered to be confusing to them. Not sure whether that is still true with screen magnifiers software these days, but obviously the same can be accomplished with copy, as long as you have space to do so.

      Hi David. Yes, you're right. I think somewhere along the way the concepts of 'opens in new window' and 'opens a new website' got conflated, leading to the ambiguity I described.

    You say words are more effective, but it sounds like you're adopting a 'don't mention external links' by default approach. So I assume your evidence is more about removing the reference as a whole, not just the icon?

      The main finding was that the icon wasn't understood by all users, so it's not an effective way of telling people that a link is to another website. There's no default approach. Content designers will continue to evaluate whether users need to know in advance that a link is external and the best way of doing this. Its just that from now the icon will not be one of the options.

    Hi Tim,
    There's some associated vulnerabilities with `target="_blank"` we should be including `rel="noopener noreferrer"` in any links, which I don't we do at the moment.

    When browsing, my way of opening links now is middle-click or cmd + click if I want a new tab or single click if I want it in the current tab.
    If single-click still opens a new tab, close the previous one.
