Schema markup: the SEO edge most sites ignore

Schema markup is code you add to your pages that helps search engines understand exactly what your content is — a business, a review, an FAQ, an article, a product. Done well, it can earn you rich results (stars, FAQs, prices) that make your listing stand out and win more clicks.

What is schema markup?

Schema markup (also called structured data) is a shared vocabulary from Schema.org, usually added in JSON-LD format. It does not change what visitors see directly — it tells search engines, in a language they trust, what each part of your page means.

Does schema markup help SEO?

Indirectly, yes. Schema is not a direct ranking factor, but it makes you eligible for rich results that increase visibility and click-through — and more clicks at the same position means more traffic. It also feeds the knowledge engines behind modern search and AI answers.

The schema types that matter most

  • LocalBusiness — essential for any business with a location; supports local SEO and Maps.
  • FAQPage — can surface your questions directly in search results.
  • Article / BlogPosting — for blog content like this.
  • Product & Review — star ratings and prices in results.
  • BreadcrumbList — cleaner, clickable result paths.
