How to Fix Schema Errors in SEO: A Guide to Technical SEO Optimization

How to Fix Schema Errors in techincal SEO

Structured data, or schema markup, plays a vital role in technical SEO. It helps search engines understand your website’s content better, which can enhance your presence in search results through rich snippets. But schema errors are common—and if left unaddressed, they can harm your site’s SEO performance.

 

Whether you manage SEO in-house or rely on SEO outsourcing India, identifying and fixing schema markup errors is essential to maintain site health and improve rankings.

 

In this guide, we’ll break down what schema errors are, how to find them, and how to fix them effectively.

 

What Is Schema Markup?

 

Schema markup is a type of structured data added to a website’s HTML to improve how search engines read and display your content. Common types of schema include:

  • Product

  • Article

  • Review

  • FAQ

  • LocalBusiness

  • Event

Search engines like Google use schema to generate rich results—like star ratings, event details, and FAQs—right in the search listings.

 

Why Fixing Schema Errors Matters for SEO

 

Schema markup is part of technical SEO, and errors in implementation can lead to:

  • Loss of rich snippets

  • Poor crawlability

  • Decreased click-through rates

  • Lower search rankings

Schema errors can signal to search engines that your website is poorly coded or untrustworthy, especially if they persist over time.

 

Common Types of Schema Errors

 

Here are some frequent schema-related issues:

1. Missing Required Properties

Certain schema types require specific properties. For instance, a Product schema needs name, image, and offers. If any of these are missing, you’ll get an error.

2. Invalid Format

This occurs when a value doesn’t match the expected format (e.g., a date in the wrong format).

3. Deprecated Schema Types

Using outdated or unsupported schema types can trigger errors or warnings.

4. Mismatch Between Schema and Visible Content

If your structured data describes something that doesn’t appear on the page, it can lead to a penalty or removal of rich results.

 

How to Identify Schema Errors

 

To fix schema errors, you first need to identify them. Here’s how:

1. Use Google’s Rich Results Test

Enter your URL or code snippet here: https://search.google.com/test/rich-results.
This tool shows you whether your structured data is eligible for rich results and flags any errors or warnings.

2. Use Google Search Console

In Search Console, go to the Enhancements tab. You’ll see schema types like Product, FAQ, Review, etc., along with the number of valid items, errors, and warnings.

3. Third-Party Tools

If you're working with SEO outsourcing India professionals or agencies, they may use tools like:

  • Schema.org Validator

  • Screaming Frog SEO Spider

  • SEMrush or Ahrefs

 

How to Fix Schema Errors

 

1. Add Missing Required Fields

Make sure you’re including all required fields for your schema type. Refer to the Schema.org documentation to verify what’s needed for each type.

Example:

json

CopyEdit

{

  "@context": "https://schema.org/",

  "@type": "Product",

  "name": "Wireless Mouse",

  "image": "https://example.com/image.jpg",

  "offers": {

    "@type": "Offer",

    "priceCurrency": "USD",

    "price": "19.99"

  }

}

 

2. Correct the Format

If you're using dates, prices, or other data, make sure the values are in the correct format (e.g., ISO 8601 for dates: 2025-08-02).

3. Remove Deprecated Properties

Check if your schema types or properties are deprecated by referring to Schema.org. Replace or remove them as needed.

4. Align Schema with On-Page Content

Ensure the structured data accurately reflects the visible content. If your schema says a page is an FAQ, it should contain visible questions and answers.

 

How Technical SEO and Schema Work Together

 

Fixing schema errors is a core part of technical SEO. It ensures your website is properly indexed, rich results are displayed, and user experience is improved. Schema also helps with:

  • Voice search optimization

  • Featured snippets

  • Click-through rates

Ignoring schema errors can hurt all these areas, especially if you’re in a competitive niche.
