You’ve probably noticed that for some Google searches using your mobile – for example, about an actor or film – you get a section at the top of your results with a summary of information from sources like Wikipedia or IMDB.

This is what Google call a 'knowledge panel'. 

These panels have been used for a range of topics for a while now, but in the UK they had never been used for health information. 

From this week, thanks to the hard work of the team, anyone who searches Google on a mobile device can find knowledge panels with reliable and authoritative health information on more than 250 conditions from the NHS website. This can help more people learn about common conditions, symptoms and treatments more quickly and easily than ever before.

To allow NHS website content to appear in knowledge panels, we had to “modularise” our content by adding structured data mark-up based on open Schema.org standards.

We talked about the work to modularise NHS website content in a previous blog post. 

In a nutshell, this involves adding mark-up to our pages to identify the specific sections of content. For example, on our pages on medical conditions we can mark-up the sections about symptoms or treatments. 

The sections of marked-up content can then be used by anyone who wants them, either by using the JSON+LD script in our page code or the free NHS API or widgets. 

We’ve added structured data mark-up to more than 250 of the most popular topics on the NHS website. 

Sections we marked-up included:

We also created short content summaries (up to 150 characters) to accompany each section we’d marked up.

During this work, we’ve helped develop a new open Schema.org standard for marking-up health information (called HealthTopicContent), which will make it easier for others to correctly mark-up their health content.

This was our first attempt to modularise NHS website content at scale, so it was a good chance for us to re-think how we produce content.

Our existing processes were designed for creating content for one platform – the NHS website – not for the modularising our content with structured data mark-up.

Modularising our content for knowledge panels allowed us to solve issues such as:

This means we’re now in a much better position to roll out modularisation more widely and move towards it being a routine part of content production.
