Structured Data Updates & Their SERP Impact

By TrackSite Admin • Jul 23, 2025 • 3 min read

In the evolving landscape of search engine optimization, structured data is one of the most underrated yet powerful tools at your disposal. It tells Google exactly what your page is about, improves search result formatting, and increases your chances of earning rich results like review stars, product pricing, FAQs, and more.

But structured data isn’t a set-it-and-forget-it feature. When competitors modify or misconfigure their schema, it can dramatically affect how they appear in search results, and offer a major opportunity for your content to shine.

What Is Structured Data?

Structured data is a standardized format used to provide explicit clues about the meaning of a webpage’s content. It’s implemented using schema.org vocabulary in JSON-LD, microdata, or RDFa, and helps search engines understand your site’s:

Products
Reviews
Recipes
FAQs
Articles
Events
Job postings

By embedding structured data, you increase your eligibility for enhanced search results—also known as “rich snippets.”

Why SERP Appearance Matters

Google’s search results are no longer just 10 blue links. They now include review ratings, product prices, image carousels, event times, FAQ dropdowns, and other elements—all powered by structured data.

When you earn these features, your listings:

Take up more visual space
Attract higher click-through rates
Build trust and authority
Increase engagement and session duration

If a competitor loses these features after changing their schema, their listings can become less competitive overnight.

How Structured Data Updates Can Help or Hurt Rankings

Structured data doesn’t directly boost rankings, but it heavily influences how your listing is presented. The impact of changes includes:

✅ Positive Effects:

Adding missing schema types (e.g. Product, Article, FAQ)
Updating outdated properties with relevant values
Fixing errors that prevent rich snippet eligibility
Enhancing content with new structured fields

❌ Negative Effects:

Removing critical schema types
Using incorrect or deprecated properties
Triggering manual penalties for spammy markup
Introducing JSON-LD errors that prevent parsing

A competitor accidentally removing review schema from a product page could cause them to lose star ratings in search results—opening a clear opportunity for your page to stand out.

Common Schema Elements to Monitor

If you’re tracking competitors, pay close attention to updates in:

@type: Have they switched from Product to Article?
aggregateRating: Are review stars no longer showing?
offers: Are prices and availability still listed?
mainEntity: Are FAQs removed or reduced?
author and datePublished: Do they update blog meta?

Even slight structural changes can alter SERP eligibility.

How to Monitor Competitor Structured Data

1. TrackSiteChanges (Recommended)

TrackSiteChanges automatically monitors structured data on competitor URLs and alerts you when it changes. You’ll get a side-by-side breakdown of new vs. old schema with highlighted diffs.

This allows you to:

See when rich snippet eligibility drops
Detect experiments with new schema types
Catch errors in competitor implementations
Improve your own markup in response

2. Schema.org Validator + Manual Checks

If you're doing periodic checks, paste a competitor's page into Google’s Rich Results Test or schema.org validator to inspect their current schema manually. Save snapshots over time to track differences.

3. Screaming Frog + Custom Extractors

For larger sites, Screaming Frog’s custom schema extractors let you crawl and export structured data across hundreds of URLs. Combine with diffing scripts to find changes.

Real Examples of SERP Impact

A product page removing offers lost its price preview and dropped in CTR by 20%.
An article adding FAQPage schema saw a 12% increase in impressions.
A competitor misconfigured their aggregateRating, causing their review stars to vanish for over a month.

These aren’t hypothetical—they happen all the time.

Final Thoughts

Structured data is a quiet but influential force in SEO. It doesn’t change your rankings directly, but it absolutely changes how users interact with your listings—and how much real estate you own on the results page.

By monitoring competitor schema updates, you gain powerful insight into their strategy, identify mistakes before they fix them, and continually refine your own approach. In a game where visibility is everything, tracking the invisible markup gives you an undeniable edge.
