How to Fix Structured Data Errors in Blogger (Step-by-Step)
Structured data is a powerful SEO tool that helps search engines understand your blog content and display rich snippets in search results. But if your Blogger blog has structured data errors, you could be missing out on valuable visibility and ranking advantages.
This complete 2025 guide will show you exactly how to identify, diagnose, and fix structured data errors in Blogger, even if you’re not a developer. With clear steps, practical tips, and real examples, you’ll ensure your blog is optimized to earn rich results that drive more clicks and traffic.
What Is Structured Data and Why Does It Matter?
Structured data is a standardized format, usually using Schema.org vocabulary, to mark up website content. It enhances your Google search listings with features like star ratings, FAQs, breadcrumbs, event details, and more. Here’s why it matters:
- Improved search visibility: Rich snippets stand out and boost click-through rates.
- Better indexing: Search engines understand your content better.
- Competitive edge: Structured data can drive more organic traffic than plain links.
Common Structured Data Errors in Blogger Sites
Though Blogger supports schema markup to some extent, many blogs experience errors due to incorrect implementation or template issues. Typical errors include:
- Missing required fields: Essential properties not included (e.g., “author”, “datePublished”).
- Invalid values: Wrong data type or format used (e.g., date format wrong).
- Duplicate fields: Schema properties repeated or conflicting.
- Incorrect nesting: Properties placed outside of the correct schema type.
- Deprecated schema types: Using old or unsupported schema vocabularies.
How to Identify Structured Data Errors on Your Blogger Site
Step 1: Use Google Search Console
Google Search Console is the primary tool to monitor structured data health.
- Log into your Google Search Console.
- Select your Blogger website property.
- Go to Enhancements > Rich Results or Enhancements > Structured Data.
- Review error reports, warnings, and valid items.
- Click on specific error types for detailed information about the affected URLs.
Step 2: Test Pages With Rich Results Test Tool
Use Google’s Rich Results Test tool to analyze individual pages for structured data errors:
- Enter the Blogger post URL.
- Run the test and see detected schema types and errors.
- Use this to confirm fixes before re-submitting to Google.
Step 3: Validate Schema with Schema Markup Validator
The Schema Markup Validator helps verify your JSON-LD or Microdata schema’s syntax and semantic correctness.
- Paste your structured data code manually or enter the page URL.
- Review warnings and errors to understand technical problems.
Step-by-Step Fixes for Common Structured Data Errors
Fix 1: Add Missing Required Properties in Blogger Template
Many errors happen because required fields like author or datePublished are missing in Blogger’s default schema markup.
- Go to your Blogger dashboard and navigate to Theme > Edit HTML.
- Locate the section where JSON-LD or Microdata schema is injected. It usually appears in <head> or near the post content.
- Add or edit JSON-LD to include missing properties. Here’s an example snippet to add under <script type="application/ld+json">:
{
"@context": "https://schema.org",
"@type": "BlogPosting",
"headline": "Your Post Title",
"author": {
"@type": "Person",
"name": "Your Name"
},
"datePublished": "2025-10-03",
"image": "https://yourblog.com/image.jpg",
"publisher": {
"@type": "Organization",
"name": "Your Blog Name",
"logo": {
"@type": "ImageObject",
"url": "https://yourblog.com/logo.png"
}
}
}Replace placeholders with your actual blog and author information.
Fix 2: Correct Date Format Errors
Structured data requires ISO 8601 date format YYYY-MM-DD or YYYY-MM-DDThh:mm:ssZ. If your template uses another format, convert it.
Example correct format:
"datePublished": "2025-10-03T07:30:00Z"Fix 3: Remove Duplicate or Conflicting Properties
Scan your template for repeated schema properties that might confuse Google’s parser. Remove one set, so each property appears only once per item.
Fix 4: Update Deprecated Schema Types
Check you’re using current schema vocabularies. For example, prefer BlogPosting over deprecated types. Use the latest Schema.org documentation.
Fix 5: Validate Structured Data After Changes
After editing your Blogger template, always re-test URLs with Rich Results Test and Google Search Console to confirm fixes.
