What is schema markup?

Schema markup is a standardized vocabulary of tags developed through Schema.org that tells search engines what a page is about. Adding it as JSON-LD in the head of an HTML page can unlock rich results such as FAQ dropdowns, star ratings, event dates, product prices, and recipe cards in Google search.

Which schema type should a page use?

Match the type to the content. Blog posts and news use Article, product pages use Product with Offer and AggregateRating, service business pages use LocalBusiness, instructional content uses HowTo, and question-and-answer sections use FAQPage. Pages can include multiple types when appropriate.

Does schema markup help SEO rankings?

Schema is not a direct ranking factor, but pages with structured data consistently earn higher click-through rates because rich results occupy more visual space in the SERP. Higher CTR correlates with improved rankings over time, and some rich result types (FAQs, HowTos) are only available to pages with valid markup.

What is the difference between JSON-LD, Microdata, and RDFa?

All three are supported schema formats. Google recommends JSON-LD because it is placed in a single script block in the head, kept separate from visible HTML, and easier to maintain. Microdata and RDFa are inline formats that attach attributes to HTML tags directly.

How is schema markup tested before going live?

Use Google Rich Results Test to validate eligibility for rich result features and Schema.org Validator for general validity. After deployment, monitor the Enhancements section in Google Search Console to track impressions and any errors that emerge as Google re-crawls the page.
