Questions
What is schema markup?
Structured data, usually a JSON-LD script in the page, that tells search engines exactly what the page is: a product with a price, a recipe with a cooking time, an event with a date. Google uses it for rich results like stars, prices and breadcrumbs.
My markup is valid. Why don’t I see rich results?
Valid markup makes a page eligible, not guaranteed. Google decides page by page, based on quality and on what it thinks helps the searcher. It can also take a few weeks after Google crawls the page again.
Do FAQ and How-to markup still work?
Barely. Since 2023 Google shows FAQ results only for well-known government and health sites, and it no longer shows How-to results at all. The markup does no harm, but don’t expect it to change how you look in search.
JSON-LD, Microdata or RDFa: which should I use?
JSON-LD. Google recommends it, and it sits in one script instead of being spread through your HTML, so it’s easier to keep correct. Microdata and RDFa still work, and we check them too.
