Structured Data Basics
Describe eligible page entities with machine-readable JSON-LD.
What this solves
Mark a free browser tool as SoftwareApplication. This pattern is useful when the business question is clear but a generic tutorial is too abstract.
The rule
Use schema types that match visible page content and validate them.
<script type="application/ld+json">{"@context":"https://schema.org","@type":"SoftwareApplication"}</script>Real-work checklist
- Define the business key and expected grain before writing the formula, query or markup.
- Test the pattern on a small known sample where you can verify the answer manually.
- Check missing values, duplicates and data types before trusting a large result.
- Scale to the real file or database only after the logic is proven.
Common mistake
Do not add schema for content that is not actually present on the page.
