Schema Markup in 2026: The Practical JSON-LD Guide
Which schema types matter in 2026, how to validate them at scale and why structured data is critical for AI Overview citation.
Schema is no longer optional. It's how Google's AI layer understands what your pages are about well enough to surface or cite them in AI Overviews. Here's what to ship in 2026.
Article schema
Every editorial URL gets Article (or NewsArticle, BlogPosting) with headline, datePublished, author and image. Authorship signals fuel EEAT.
Product schema
Product + Offer + AggregateRating on every SKU. Without it, you forfeit rich snippets and shopping-graph eligibility.
FAQPage and HowTo
FAQ schema still wins SERP real estate where Google chooses to render it, and feeds AI Overview citation. HowTo similarly helps for procedural content.
Breadcrumb and Organization
Breadcrumb on every deep page; Organization once sitewide. Both clarify your information architecture to crawlers and AI summarisers.
Validate continuously
Broken schema is invisible to humans. Validate weekly against Google's rich results test and alert on regressions the day they ship.
