Schema markup is a type of structured data added to a webpage’s HTML that helps search engines better understand the content on the page. It provides clear context about what the content represents such as a product, article, review, event, video, or business.
Schema markup uses a standardized vocabulary from Schema.org, which is supported by major search engines like Google.
In simple terms:
👉 Schema markup helps search engines understand meaning, not just text.
How Schema Markup Works
Schema markup works by labeling specific pieces of information on a page so search engines can interpret them accurately.
The process looks like this:
- You add structured data (usually in JSON-LD format) to a page
- Search engines crawl and read the markup
- The content becomes eligible for enhanced search features
- Your page may appear as a rich result in SERPs
Schema does not guarantee rich results, but it makes your content eligible for them.
Why Schema Markup Is Important for SEO
Schema markup is important because it:
- Improves search result visibility
- Enables rich snippets and rich results
- Increases click-through rates (CTR)
- Helps search engines understand content context
- Supports semantic and entity-based SEO
Even if rankings stay the same, schema can significantly improve how your listing appears in search results.
Common Types of Schema Markup
There are many schema types, but these are the most commonly used in SEO:
1. Article Schema
Used for blog posts, news articles, and guides.
2. Product Schema
Displays price, availability, ratings, and reviews for products.
3. FAQ Schema
Shows expandable questions and answers directly in search results.
4. Review & Rating Schema
Displays star ratings and review counts.
5. Local Business Schema
Provides business name, address, phone number, hours, and location details.
6. Video Schema
Helps videos appear in video-rich results and carousels.
Schema Markup Example
Here’s a simple example of FAQ schema using JSON-LD:
<script type="application/ld+json">
{
"@context": "https://schema.org",
"@type": "FAQPage",
"mainEntity": [{
"@type": "Question",
"name": "What is schema markup?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Schema markup is structured data that helps search engines understand webpage content."
}
}]
}
</script>
JSON-LD is the recommended format because it’s clean and easy for search engines to read.
