Chances are, you’ve already heard of JSON-LD — you might even be using it already. Kudos to you if that’s the case. If you haven’t heard of it, I’d urgently recommend you to read up on what is becoming an ever-more important part of SEO. Its increasing importance is down to its selection as Google’s structured data approach of choice, as it’s more flexible than microdata and more easily maintainable in the long run.
What do I mean by more flexible? Put simply, JSON-LD lets you place all your structured data between a special pair of <script> tags in the <head> of the HTML, much as you would with Google Analytics tracking snippets or canonical tags. No more bugging your developers to make simple changes. Compared to the old ways of adding structured data, that’s a big improvement.
