Check your structured data markup
Structured data helps search engines show rich results for your pages. SiteCurl checks for valid JSON-LD and schema.org markup.
No signup required. Results in under 60 seconds.
What this check does
SiteCurl looks for JSON-LD structured data on your pages. It checks whether any schema.org markup is present and whether it is valid. Structured data tells search engines what your page is about in a format they can parse directly.
The check flags pages with no structured data, which means search engines have to guess at your content type. Pages with valid markup are eligible for rich results like star ratings, FAQ dropdowns, product prices, and recipe cards.
Why it matters
Rich results stand out in search. Pages with star ratings, FAQ sections, or product prices in the search listing get more clicks than plain blue links. Structured data is what makes those extra details possible.
AI search tools also rely on structured data. When ChatGPT, Perplexity, or Google AI Overviews build answers, they look at structured markup to understand your content. Pages with clear structured data are more likely to be cited as sources.
How to fix it
Add JSON-LD markup to your pages. The most common types are Organization, WebPage, Article, FAQ, Product, and BreadcrumbList. You can add JSON-LD in a script tag in the head or body of your page.
Start with Organization markup on your home page and Article markup on blog posts. If you have a FAQ section, add FAQPage schema. Each type has specific required fields listed on schema.org.
Test your markup with Google's Rich Results Test after adding it. Then run a SiteCurl scan to confirm it is detected across all your pages.

Frequently asked questions
What types of structured data should I add?
Start with Organization on your home page. Add Article to blog posts, FAQPage to FAQ sections, and Product to product pages. Each type unlocks different rich result formats.
Does structured data affect rankings?
Not directly. But rich results increase click-through rates, which means more traffic from the same ranking position. Pages with rich results also tend to look more trustworthy.
What is JSON-LD?
JSON-LD is the format Google recommends for structured data. It is a script tag you add to your HTML that contains machine-readable info about your page. It does not change how the page looks to visitors.
