Schema markup is structured data code added to a website that helps search engines better understand the content on a page.

It uses a standardized vocabulary from Schema.org to explain:

what the page is about
what entities are mentioned
how information should be interpreted

Schema helps Google display rich search results such as:

star ratings
FAQs
recipes
product prices
business details
event information

Simple Example

Without schema, Google reads:

“Pizza Palace is open from 10 AM to 11 PM.”

With schema, Google clearly understands:

business name
opening hours
address
phone number
reviews

Why Schema Markup Matters for SEO

Schema markup helps with:

1. Better Search Understanding

Google understands entities and page meaning more accurately.

2. Rich Results (Rich Snippets)

Schema can improve how listings appear in search results.

Examples:

breadcrumbs
recipes
event dates

These improve visibility and CTR.

3. Voice Search & AI Search

Types of Schema Formats

Google supports multiple formats, but prefers:

This is the modern standard.

Example:

<script type="application/ld+json">
{
 "@context": "https://schema.org",
 "@type": "LocalBusiness",
 "name": "ABC Dental Clinic",
 "telephone": "+1-555-555-5555",
 "address": {
   "@type": "PostalAddress",
   "streetAddress": "123 Main Street",
   "addressLocality": "Dallas",
   "addressRegion": "TX"
 }
}
</script>

Other Formats

Less commonly used:

Microdata
RDFa

JSON-LD is easiest and most SEO-friendly.

How Schema Helps Google

Schema provides explicit context.

Instead of guessing:

Apple

Google can understand whether it means:

the fruit
the company
a product
a location

This improves entity SEO.

Schema and Rich Results

Not all schema guarantees rich snippets.

Google decides whether to display them based on:

trust
relevance
content quality
search intent

But schema increases eligibility.
