Schema Markup Explained: How Structured Data Helps Your Website in Google
What schema markup (structured data) is, how it helps Google understand your business, which types small businesses should use, and how to add and test it on WordPress.

On this page
- Schema markup tells search engines exactly what your content is: business, service, product, article or FAQ.
- It can make pages eligible for rich results but doesn't guarantee rankings.
- Only mark up visible content, never fake reviews, and test with Google's tools.
Schema markup is extra code that tells search engines exactly what your content is about: that a page is about a business with certain opening hours, a product with a price, an article with an author, or a list of FAQs. It doesn't change how your page looks to visitors, but it helps Google understand and present it.
Why schema markup matters
- Clarity: search engines understand your business name, services, location and contact details without guessing
- Rich results: some types can make your listing eligible for enhanced displays, such as product prices, ratings, breadcrumbs or event details
- AI and answer engines: clearly structured information is easier for search features and AI assistants to use accurately
Schema doesn't guarantee higher rankings or rich results, but it removes ambiguity, which is always a good foundation.
Structured data is also part of being understood by AI tools; see AI search and your website.
Schema types small businesses should know
| Type | Use it for |
|---|---|
| LocalBusiness / ProfessionalService | Your business name, address, phone, hours and area served |
| Organization / Person | Company or personal brand details, logo and social profiles |
| Service | Individual service pages |
| Product | Items in an online store (price, availability) |
| Article / BlogPosting | Blog posts, with author and dates |
| FAQPage | Frequently asked questions on a page |
| BreadcrumbList | Your site's page hierarchy |
| Event, Recipe, Course, Restaurant | Specialist content types |
How to add schema on WordPress
- SEO plugins like Rank Math or Yoast add Organization, Article, Breadcrumb and basic page schema automatically, and let you choose schema types per page.
- WooCommerce adds Product schema for store items.
- Custom JSON-LD can be added for anything specific, such as detailed service or FAQ schema.
Rules to follow
- Only mark up what's visible on the page. Schema must match real content.
- Never fake reviews or ratings in schema. It violates Google's guidelines.
- Keep details consistent with your Google Business Profile and contact page.
- Avoid duplicate, conflicting schema from multiple plugins.
How to test it
- Google's Rich Results Test: checks eligibility for rich results
- Schema Markup Validator (schema.org): checks the code is valid
- Search Console enhancements reports: show errors across your site

A practical example
This website uses structured data throughout: business and person details on the homepage, Service and FAQ schema on each service page, BlogPosting on articles, and breadcrumbs everywhere. It's part of a complete WordPress SEO setup. For more SEO terms, see the website glossary.
