Key takeaways

Schema markup is a type of structured data that uses Schema.org vocabulary.
JSON-LD is the recommended format for implementation.
Schema enables rich results (e.g., star ratings, FAQs) that can improve click-through rates.
It does not directly influence rankings but supports better search interpretation.
Always test your schema with Google's Rich Results Test before going live.

Schema markup is also called structured data and is based on Schema.org vocabulary.

Example

A recipe page includes a Recipe schema with properties: name, image, cookTime, nutrition.calories, recipeIngredient, recipeInstructions.
Google can display the recipe as a rich result with a photo, star rating, and cooking time directly in search results.
Example JSON-LD snippet:

{
    "@context": "https://schema.org",
    "@type": "Recipe",
    "name": "Chocolate Chip Cookies",
    "recipeIngredient": ["1 cup flour", "1/2 cup sugar"],
    "cookTime": "PT10M"
  }

When Should I Use Schema Markup?

Your page contains content that maps directly to a schema type (e.g., product, review, event, FAQ, local business, article).
You want to increase click-through rates by appearing with rich snippets.
You need to clarify ambiguous content (e.g., a business name vs. an event name).
You are publishing content that Google explicitly supports for rich results (see Google Search Gallery).

What Schema Markup Is Not

A ranking guarantee: Schema does not directly boost search position, but it can improve visibility.
A quick fix: It requires careful implementation and testing.
Hidden content: Schema must reflect visible page content—no misrepresentation.
A substitute for quality: It does not fix thin content, poor crawlability, or weak internal linking.

Quick Start: Add Schema Markup in 4 Steps

Identify the schema type that matches your content (e.g., Product, FAQ, Event).
Write JSON-LD code manually or use a generator (e.g., Google's Structured Data Markup Helper).
Embed the code into your page’s <head> or within the <body>.
Test using Google Rich Results Test to ensure validity and eligibility.

Common Mistakes

Using schema that does not match visible content: This can lead to manual penalties.
Expecting automatic ranking improvement: Schema enables rich results, not direct ranking gains.
Skipping testing: Invalid or incomplete markup will not work.
Treating schema as an SEO shortcut: Without strong content, schema has limited impact.
