Schema Audit Score

Gauge your structured data health at a glance—unlock richer search features, fewer markup errors, and stronger organic visibility.

Updated Aug 02, 2025

Quick Definition

Schema Audit Score is a rating that shows how complete and error-free a webpage’s structured data (schema markup) is, based on tests of format, accuracy, and adherence to search-engine guidelines.

Definition

Schema Audit Score is a numerical or graded rating (often 0-100 or A-F) that represents how complete, accurate, and guideline-compliant a page’s structured data is. The score is produced by a validation tool that checks the markup’s syntax (e.g., JSON-LD, Microdata), compares each property against schema.org definitions, and flags anything that blocks eligibility for rich results in Google, Bing, or other search engines.

Why It Matters in Search Engine Optimization

Search engines rely on structured data to understand page content and qualify it for rich snippets—stars, FAQs, event dates, and more. A high Schema Audit Score signals three things:

  • Crawl efficiency: Robots spend less time guessing what’s on the page.
  • Rich-result eligibility: Fewer warnings and errors mean a higher chance of eye-catching SERP features.
  • Trust: Clean markup reduces the risk of manual penalties for spammy or misleading schema.

How the Score Is Calculated (Beginner Level)

Most schema audit tools follow a similar checklist:

  • Syntactic validity: Does the JSON-LD parse without errors? Are curly braces and quotes in the right places?
  • Type accuracy: Are you using the correct @type (e.g., Product vs. Organization) for the page’s main entity?
  • Required properties: Google’s documentation lists mandatory fields for each rich result (e.g., name, image, and offers for products). Missing one drops the score.
  • Recommended properties: Optional fields add context and can boost the score.
  • Conflict checks: Does the structured data contradict visible content (price, availability, dates)? Mismatches trigger errors.
  • Guideline compliance: Tools reference search-engine policies to flag prohibited or deceptive markup.

The final score is a weighted sum of passed versus failed checks. An “A” or 90-100 typically means “rich-result ready.”

Best Practices to Improve Your Score

  • Select the most specific @type available (Recipe beats Article for cooking pages).
  • Add all required and as many recommended properties as you can supply.
  • Use JSON-LD—it’s Google’s preferred format and keeps markup separate from HTML.
  • Validate in multiple tools: Google Rich Results Test, Bing Markup Validator, and Schema.org’s validator.
  • Monitor Search Console → Enhancements for live error reports.
  • Re-audit after CMS updates or template changes; one misplaced variable can tank scores site-wide.

Real-World Examples

  • E-commerce product page: After adding missing sku and aggregateRating, the score rose from 72 to 98, unlocking review stars in Google results within a week.
  • News article: An editor removed the author field; the score dropped to 55, and the Top Stories carousel visibility disappeared until fixed.
  • Local business landing page: Adding geo coordinates and openingHours raised the score to 100 and populated the business panel with hours and map pins.

Common Use Cases

  • Site migrations: Confirm that new templates preserve structured data integrity.
  • Content audits: Prioritize pages with high traffic potential that currently score below 80.
  • Agency reporting: Provide clients with a tangible KPI alongside rankings and traffic.
  • Plugin QA: Evaluate the output of WordPress or Shopify schema plugins before pushing live.

Frequently Asked Questions

What is a Schema Audit Score?
A Schema Audit Score grades how complete and error-free your structured data markup is, usually on a 0–100 scale. The score looks at factors like missing required properties, syntax errors, and use of recommended enhancements.
How do I check my website's Schema Audit Score?
Run your URL through an SEO crawler or structured-data tool that includes a schema audit feature, such as Screaming Frog with the Schema plugin or Sitebulb. The report will list your score and pinpoint which pages or properties need attention.
Why is my Schema Audit Score lower than my competitor's?
Common reasons include missing required properties (e.g., price on Product schema), using outdated schema types, or having duplicate IDs. Compare your markup side-by-side with the competitor’s and update or expand properties to close the gaps.
Does a higher Schema Audit Score guarantee rich snippets in Google?
No. A solid score means your markup is eligible, but rich snippets still depend on Google’s algorithms and SERP testing. Think of the score as clearing the technical hurdle; content relevance and search intent still decide snippet appearance.
How can I fix errors that drag down my Schema Audit Score?
Start with the highest-priority warnings in the audit report—usually red or critical items. Add missing required fields, remove typos, and validate again with Google’s Rich Results Test to confirm the fixes before re-crawling your site.

Self-Check

In plain terms, what does a Schema Audit Score tell you about a webpage?

Show Answer

It indicates how completely and correctly the page’s structured data (Schema.org markup) is implemented. A high score means search engines can parse the markup without errors or gaps, boosting eligibility for rich results; a low score flags missing, invalid, or poorly nested schema that can limit visibility.

Your product page returns a Schema Audit Score of 45/100. Which immediate consequence is most likely in Google’s results?

Show Answer

The page can still rank, but it is unlikely to trigger rich result features such as price, rating stars, or availability. These enhanced snippets require clean, comprehensive schema, so a 45/100 score usually means those elements are either missing or invalid.

You fix JSON-LD errors on a blog post and add Author, PublishedDate, and ArticleSection properties. The Schema Audit Score jumps from 60 to 90. What practical benefit should you monitor over the next few weeks?

Show Answer

Watch for higher click-through rates from search results. The added properties make the post eligible for article rich snippets (e.g., byline, date). If Google surfaces those elements, the listing becomes more informative, which often translates into more clicks without changing the ranking position.

Name two quick, low-effort actions that typically raise a Schema Audit Score on an ecommerce site.

Show Answer

1) Add required properties to the Product schema—price, currency, availability, and SKU—so the markup meets Google’s guidelines. 2) Validate all structured data through Rich Results Test or Schema.org validator and remove any deprecated or misspelled attributes. Both steps close common gaps and bump the score with minimal development time.

Common Mistakes

❌ Treating the Schema Audit Score as a vanity metric—aiming for 100 without asking whether the markup actually reflects key business entities (products, services, FAQs, etc.)

✅ Better approach: Start with a content-to-schema map. List the revenue-critical page types, decide which schema classes and properties matter for each, then optimize those first. Accept that some low-value pages may never hit a perfect score—and that’s fine.

❌ Running the audit on the homepage only and assuming the rest of the site is covered

✅ Better approach: Crawl representative URLs for every template (product page, blog post, location page, etc.). Use a crawler that extracts JSON-LD/Microdata at scale, export the findings, and fix gaps template-by-template rather than page-by-page.

❌ Leaving fields blank or misaligned with on-page content (e.g., price in markup doesn’t match visible price), which triggers rich-result rejections

✅ Better approach: Set up a nightly test that compares key schema fields against DOM values. Fail the deploy if there’s a mismatch. For static sites, a GitHub Action with a structured-data linter works; for headless CMS, add the check to the build pipeline.

❌ Ignoring schema after site redesigns or CMS/plugin updates, letting outdated properties (e.g., old ImageObject URLs or deprecated ‘itemtype’ values) drag the score down over time

✅ Better approach: Add a recurring quarterly schema audit to the SEO calendar. Automate alerts for deprecated properties using Search Console’s rich-results report or a webhook from your auditing tool so fixes happen before traffic drops.
