What Is Schema.org?
Schema.org is the shared vocabulary that powers structured data across the web. Learn how Schema.org helps search engines and AI systems understand businesses, websites, and other real-world entities.
Search engines need a common language.
Without one, every website could describe the same business in completely different ways.
Schema.org provides that shared vocabulary.
It gives websites a standardized way to describe businesses, people, organizations, products, events, and many other real-world entities so search engines and AI systems can interpret them consistently.
What is Schema.org?
Schema.org is an open vocabulary used to organize structured data.
Instead of inventing your own labels, you use standardized terms that search engines already understand.
For example, rather than simply displaying a phone number, Schema.org lets you identify it specifically as a business telephone number.
That removes ambiguity and improves machine understanding.
How it works
Schema.org defines thousands of standardized properties.
Businesses commonly use it to describe:
Business name
Address
Phone number
Website
Business category
Services
Hours
Geographic location
Social profiles
Those standardized labels become part of the structured data published on a website.
Why it matters
Search engines compare information from many trusted sources.
When your website uses Schema.org vocabulary and that information matches your listings across Maps, directories, and review sites, confidence increases that every source describes the same business.
That stronger confidence supports:
Better entity recognition
Stronger knowledge graph connections
More accurate AI-generated answers
Improved business understanding
Schema.org and JSON-LD
Schema.org defines the vocabulary.
JSON-LD is one of the formats used to publish it.
Think of Schema.org as the dictionary and JSON-LD as the language used to deliver those definitions to search engines.
They work together to help machines understand your website more accurately.
Keep your data consistent
Schema.org works best when it matches the visible information on your website and the information published elsewhere online.
Consistency—not quantity—is what builds trust.
Key takeaway
Schema.org gives websites a common vocabulary that search engines and AI systems understand.
Combined with accurate structured data and consistent business information, it strengthens your digital identity across the web.

What Is JSON-LD?
JSON-LD is the most common format for adding structured data to websites. Learn how JSON-LD helps search engines understand businesses without changing what visitors see.
Adding structured data to a website doesn't have to change what visitors see.
Instead, it can be added behind the scenes in a format that search engines can easily understand.
The most common format for doing this is JSON-LD.
What is JSON-LD?
JSON-LD stands for JavaScript Object Notation for Linked Data.
It is a structured way to describe information about a webpage or business using clearly labeled data.
Visitors never see it.
Search engines and AI systems read it while crawling your website.
Why search engines recommend it
JSON-LD separates structured data from the visible content on a webpage.
That makes it easier to maintain and reduces the chance of accidentally changing the page layout.
It also allows developers to update structured information without rewriting page content.
What can JSON-LD describe?
Businesses commonly use JSON-LD to identify:
Business name
Address
Phone number
Website
Business category
Services
Hours
Service areas
Social profiles
These attributes help search systems understand exactly what the business represents.
JSON-LD supports entity recognition
JSON-LD does not improve visibility by itself.
Instead, it gives search engines another trustworthy source of structured information.
When JSON-LD matches information found on your website, Maps, directories, and other trusted sources, confidence increases that all references describe the same business.
Keep it accurate
Like every other business signal, JSON-LD should always match your visible website information.
Outdated or incorrect structured data can create confusion just as inconsistent business listings can.
Maintaining accurate information everywhere is far more valuable than simply adding more markup.
Key takeaway
JSON-LD is the preferred format for publishing structured business data on modern websites.
Combined with accurate business information and consistent entity signals, it helps search engines and AI systems understand your business with greater confidence.
