Structured data breaks silently

A deploy removes a field. A theme update rewrites the template. Google drops your rich results and you find out weeks later, when rankings have already fallen.

🔕

No native browser warning

Invalid JSON-LD silently fails. The page loads fine. You would never know without checking.

Google takes days to reflect changes

By the time you notice the rich snippets are gone, you have already lost impressions and clicks.

apild tells you immediately

Validate now for free. When monitoring launches, get alerted the moment something breaks.

Validation in three steps

1

Paste or fetch

Paste raw JSON-LD directly, or enter a URL and we'll fetch the page and extract all structured data blocks automatically.

2

Instant validation

We check every block against Google's rich result rules (required fields, recommended fields, and common mistakes per Schema.org type).

3

Fix before it hurts

Errors shown with the exact field path and a plain-English explanation. No jargon, no guessing what Google actually requires.

The types that drive Google rich results

Validation rules are sourced directly from Google's rich results documentation, not the raw Schema.org spec. We check what Google actually requires.

Structured data is the language AI speaks

Google AI Overviews, ChatGPT, and Perplexity rely on JSON-LD to understand and cite your content. Research shows that knowledge graph representations of content can more than triple the accuracy of LLM answers compared to unstructured data.1

Broken JSON-LD means you're invisible to both Google rich results and AI answers. The same validation, twice the reason to get it right.
