Google Search works hard to understand the content of a page. You can help us by providing explicit clues about the meaning of a page to Google by including structured data on the page. Structured data is a standardized format for providing information about a page and classifying the page content; for example, on a recipe page, what are the ingredients, the cooking time and temperature, the calories, and so on.
Google uses structured data that it finds on the web to understand the content of the page, as well as to gather information about the web and the world in general.

Using Google Tag Manager to Dynamically Generate Schema/JSON-LD Tags (Learn more)
Use Google Tag Manager to insert the code with the "Custom HTML" tag. (See screenshot below.) Why Tag Manager? Because Tag Manager can dynamically change the Structured Data based on the content of the page! (eg: Blog posts) See this article and this older Moz article for more information on how to do that.
UPDATE: Google changed something. Now, in order to have the Structured Data Testing tool detect inserted Structured Data properly, it must be inserted programatically. Pasting your desired Structured Data within this snippet below will allow it to be detected properly by the testing tool.
