What Is Schema Markup? Helping Search Engines Read a Website

Schema markup is a bit of structured code that gets added to a website to help search engines understand the content more precisely. When a dental practice’s website says “Dr. Sarah Chen, Cosmetic Dentistry, 123 Main Street, Portland,” a human reader understands that’s a dentist’s name, specialty, and address. Search engines can usually figure it out too, but schema markup removes the guesswork entirely by explicitly labeling each piece of information in a standardized format.

The most visible benefit is rich results in Google. A business with proper schema might show star ratings, business hours, price ranges, or FAQ dropdowns directly in the search results page. These enhanced listings take up more space and tend to attract more clicks than plain results. FAQ schema is particularly useful because it can make a page’s questions and answers appear as expandable sections right in Google’s results.

For AI visibility, schema markup makes a business’s information easier for AI platforms to extract and use accurately. When an AI model encounters a page with LocalBusiness schema that cleanly labels the business name, address, services, and hours, it can pull those facts with higher confidence than when parsing unstructured text.

The most important schema type for local businesses is LocalBusiness, which covers the core business details: name, address, phone number, opening hours, service area, and accepted payment methods. Adding this to the website essentially gives search engines and AI platforms a structured summary of the business that’s easy to read and impossible to misinterpret.

Implementation is the main barrier. Schema markup is a block of JSON-LD code added to the page’s HTML header, and while the format is standardized, getting all the details right requires some technical comfort. Many website platforms offer plugins that generate schema automatically, and for businesses working with a web developer, it’s usually a straightforward one-time setup.
