If you’ve ever looked into how to optimise your content for voice search, or for discovery on voice devices, you’ve probably come across recommendations to mark up your content with schema.

Schema.org is a type of structured data markup – essentially, a kind of code – that you include in your webpages to make them easier for search engines to understand. It’s designed to be a universal “search engine language”, and was jointly developed by Google, Microsoft, Yahoo!, and Yandex.

It has numerous benefits for SEO, not least of which is the fact that if search engines can better understand what your content is about, it’s more likely to be surfaced as a relevant result for a user’s search.
