The New World of JSON
JSON tagging for various reasons has been on the increase for a couple of years as Google pushes us towards rich results and an information first SERPs.
As an SEO agency we see these trends as they emerge and how they evolve over time, in the case of JSON we've moved purely from an information-providing-code to a fully fledged fight for position 0 and potentially unlimited options for optimisation.
JSON for the future
The type of elements you should be tagging are the types of elements Google is talking about, it's that simple.
At the moment Google is leading web owners and SEO agencies through core updates that place focus on people associated to businesses or websites. This is particularly important for news outlets with specific journalists, but also for websites looking to capture target markets.
For example, web development agencies can tag specialist developers, who can tag associated service pages, social profiles, onsite articles and even secondary blogs.
The power of this type of tagging should not be understated - this is the long awaited coming together of tech and content marketing into the mainstream. The strength of a well rounded SEO team has never been more important.
Beyond people, JSON tagged to target areas and markets, product or service costs and core company information - including founders - will be expanded.
All of these will filter into SERPs, so technical SEO strategy should have JSON at its core.
