What is schema markup?
Schema markup is structured data added to HTML pages in JSON-LD (or Microdata/RDFa) format that helps search engines understand the content and context of a page. It comes from Schema.org, a vocabulary developed collaboratively by Google, Bing, Yahoo, and Yandex.
Types of schema markup that matter
Schema markup does not directly improve rankings, but it can significantly impact how your pages appear in search results. Properly implemented schema enables rich results: star ratings, FAQs, How-To steps, event dates, recipe details, and more.
The most impactful schema types for most sites are Organization (for the homepage), Service or Product (for service/product pages), FAQPage (for Q&A sections), BreadcrumbList (for navigation structure), and Article (for blog content).
Example
Example
A software product page with Product schema and AggregateRating can appear with star ratings in the SERP, significantly increasing CTR compared to a plain listing.
Frequently asked questions
Does schema markup improve rankings?
Not directly. It improves how results display (stars, FAQs, breadcrumbs), which lifts click-through rate, and it sharpens how search engines and AI systems understand the entities on the page.
Which schema types should most sites implement first?
Organization on the homepage, Service or Product on commercial pages, BreadcrumbList sitewide, FAQPage on question-rich pages, and Article on editorial content. Validate everything with Google’s Rich Results Test before shipping.
