Schema markup is code that helps search engines and AI systems understand your website. It labels your business information in a format machines can parse.
You don't need to be technical to understand why this matters. You just need to know that AI systems work better with explicit information than scattered hints, and schema markup is how you provide it. JSON-LD is the most common way to add schema to a page. For the technical version, see What Is JSON-LD?.
The problem schema solves
Your website has information about your business: name, address, hours, services, reviews. To a human reading the page, this makes sense. To a machine, it's just text.
Consider your business address. On your site, it might appear as "123 Main Street, Austin, TX 78701" in your footer. A human knows that's where you're located. A machine sees a string of text that could mean anything.
Pro Tip
Schema markup wraps that text in code that says "this is a postal address, and here's the street, city, state, and zip broken out." Now the machine has a cleaner version of the fact.
Why AI cares about schema
AI systems making recommendations need to understand businesses clearly. They're pulling information from millions of websites and trying to organize it into coherent knowledge about local businesses.
Schema markup makes that job easier. When your site has proper schema, AI can extract your business information with more confidence. When it doesn't, the AI has to infer more from page copy and third-party sources.
Important
Schema can describe facts already visible on the page. It does not guarantee that a search or AI product will retrieve, cite, or recommend the business.
Schema types that matter for local businesses
LocalBusiness is the foundation. It defines your business name, address, phone, hours, and general category. Every local business website should have this.
More specific types are better when they exist. If you're a plumber, use the Plumber schema type. If you're a salon, use BeautySalon. These give AI more context about your business category.
Service describes a real offering and can connect it to the provider and area served. The Service schema guide for local businesses explains when this belongs on a location page and what it cannot promise.
OpeningHoursSpecification tells AI when you're open. This is important for time-sensitive recommendations.
FAQPage marks up useful questions and answers that are visible on the page.
sameAs links connect your website to verified profiles across Google, Yelp, Facebook, BBB, Apple Maps, Bing Places, and relevant industry directories.
Review and AggregateRating require care. Google's guidance is narrower than many local SEO plugins imply, especially for LocalBusiness pages that publish reviews about themselves. Validate the use case before adding it.

How schema appears on your site
Schema markup lives in your website's code, not in the visible content. It's typically added as a JSON-LD script in your page's head section.
You won't see it when you look at your website, but AI systems see it when they crawl your pages. It's metadata: information about your information.
How to implement it
If you're using WordPress, there are plugins like Yoast SEO and Schema Pro that add schema markup without requiring you to touch code. Most modern website builders have similar options.
If you have a custom website, your developer will need to add the JSON-LD manually. Basic LocalBusiness schema is a small technical task, but multi-location brands should be more careful: each location page needs its own clean entity data, and the corporate brand should connect to locations consistently. The LocalBusiness schema guide for multiple locations covers that portfolio pattern and the rollout checks it needs.
If the same brand, location, or service area appears differently across listings and pages, use the multi-location entity fragmentation guide before adding more markup.
Pro Tip
After implementation, test with Google's Rich Results Test. Run the page URL through the tool to see which schema it detects and whether it flags errors.
What happens without schema
Your website still works. Humans can still find and read it. But you're making AI systems do extra work to understand you, and some retrieval systems will lean more heavily on third-party sources.
Important
In a competitive market where AI recommendations matter, that extra friction can be the difference between getting recommended and being left out of the answer. Schema markup reduces that friction.
