How to Fix Schema Markup Errors in Google Search Console

Schema markup helps search engines understand the structure and meaning of website content. When implemented correctly, structured data can make pages eligible for enhanced search results such as review stars, FAQs, product information and other rich results.

However, schema markup errors are common, particularly when structured data is generated automatically by plugins or implemented incorrectly.

If Google Search Console reports schema markup errors, it usually means that the structured data on your website is incomplete, invalid or conflicting with other markup on the page.

This guide explains the most common schema markup errors and how they can be resolved.

What Schema Markup Errors Mean

Google Search Console reports structured data issues when it detects problems with the schema markup on your website.

These problems typically fall into three categories:

• invalid schema markup
• missing required fields
• conflicting structured data

When these errors occur, the page may still be indexed, but it may not qualify for rich results in search.

Where to Find Schema Markup Errors

The easiest way to identify schema markup problems is through Google Search Console.

You can find structured data issues by navigating to:

Search Console → Enhancements

This section lists all detected schema types and highlights any errors or warnings affecting them.

Each issue typically includes a description of the problem and the pages affected.

Common Schema Markup Errors

There are several types of errors that commonly appear in Search Console.

Missing Required Fields

Many schema types require specific properties to qualify for rich results.

For example:

• product schema may require price and availability
• review schema may require ratingValue
• article schema may require headline

If required fields are missing, Google will flag the structured data as incomplete.

Invalid Structured Data Format

Schema markup must follow the correct syntax and structure.

Errors may occur when:

• properties are incorrectly formatted
• schema types are used incorrectly
• required nesting is missing

Even small syntax errors can prevent Google from recognising the markup.

Conflicting Schema Markup

Sometimes multiple plugins generate schema markup on the same page.

This can lead to conflicts such as:

• duplicate schema types
• inconsistent structured data
• overlapping markup

When this occurs, search engines may ignore the markup entirely.

Incorrect Schema Type

Using the wrong schema type for the page content can also cause issues.

For example:

• using Product schema on a service page
• applying Review schema incorrectly
• marking generic pages as articles

Choosing the correct schema type is essential for structured data to work properly.

How to Test Schema Markup

After fixing schema issues, it is important to test the markup to confirm that it is valid.

Google provides two tools that are commonly used:

This tool checks whether the page is eligible for rich results.

This tool validates structured data against schema.org standards.

Testing helps ensure that the markup is recognised correctly by search engines.

Why Schema Markup Errors Happen

Many websites rely on plugins to generate schema markup automatically.

While these tools are convenient, they often produce incomplete or conflicting structured data, particularly when multiple SEO or schema plugins are installed.

Other common causes include:

• outdated schema implementations
• theme-generated structured data
• incorrect manual schema code
• JavaScript-based markup not being rendered correctly

Diagnosing these issues often requires a detailed review of the structured data being generated across the site.
