What Is Schema Markup?

Search engines are excellent at reading text and mediocre at knowing what it is. Is “4.8” a rating, a version number or a price? Schema markup removes the guesswork: a machine-readable annotation that says “this page is a product; its price is $99.99; it's in stock.” Search engines repay the favor with richer listings.

What it looks like

The recommended format is JSON-LD — a script tag of structured JSON using the schema.org vocabulary, invisible to visitors:

<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "Product",
  "name": "Wireless Headphones X200",
  "offers": { "@type": "Offer", "price": "99.99",
              "priceCurrency": "USD" }
}
</script>

Older formats (microdata woven into HTML attributes) still work, but JSON-LD keeps data separate from presentation, which is why Google recommends it and why generators produce it.

What rich results actually get you

Structured data is not a ranking factor — Google says so plainly. Its value is real estate and click-through: FAQ markup can expand your listing with dropdowns, product markup shows price/availability/stars, article markup feeds Top Stories and Discover, local business markup powers the map panel, recipe markup earns image thumbnails. A rich listing occupies more of the results page and signals legitimacy — both of which lift CTR even at the same position.

The types worth implementing first

FAQPage — any page with question/answer content.
Article / BlogPosting — posts and news, with author and dates.
Product + Offer — anything with a price; the highest-impact type for e-commerce.
LocalBusiness — name, address, phone, hours for any physical business.
BreadcrumbList, Organization, WebSite — site-level plumbing that helps every page.

The rules Google enforces

One rule dominates: markup must describe content visible on the page. FAQ schema for questions that appear nowhere, review stars with no reviews, prices that don't match — these earn manual actions that remove rich results site-wide. Beyond that: put required properties in (a Product needs an Offer; an Article wants author, date and image), keep values accurate, and re-validate after site changes.

Validate or it didn't happen

Two free checks: Google's Rich Results Test(is this eligible for rich results?) and the schema.org validator (is the JSON structurally sound?). After deploying, Search Console's Enhancements reports show which pages earned rich results and which have errors — worth checking monthly.

Generate yours without hand-writing JSON

The schema markup generatorbuilds valid FAQ, Article, LocalBusiness and Product JSON-LD from a plain form — copy the script block, paste it into your page's head. Round out the search appearance with the meta tag generator and preview the result in the SERP snippet preview.
