Information with explicit labels and relationships
Structured data expresses information in a form that software can interpret consistently. On a website, JSON-LD can describe an article, its author and its relationship to the publishing organisation. The visible page still provides the information and experience for the person reading it.
Google supports several markup formats and recommends JSON-LD for its search features. The data must describe the relevant visible content and satisfy the applicable feature requirements. See Google’s structured data guidelines.
Example: publishing a knowledge article
An article page may contain a headline, explanatory text, an author attribution and a publication date. Its structured data should reflect those actual details. If an editor changes the headline or corrects the author, the machine-readable information needs to stay aligned.
Prefer a maintainable connection to the page’s real fields over a separate block that must be manually updated each time. In a WordPress workflow, review what the chosen SEO plugin already emits before adding custom data. Clear responsibility reduces the chance of two sources describing the same page differently.
Validate output and editorial accuracy separately
Use a suitable validator to identify syntax and property issues, then inspect the content it describes. A technically accepted date can still be wrong; a correctly formatted organisation name can still refer to a previous brand. Automated checks and editorial review solve different problems.
- Check the data on the final public URL.
- Review references to images, authors and canonical pages.
- Confirm that template changes have not duplicated entities.
- Recheck representative pages after plugin updates.
Keep a brief record of why each data type exists. That makes later maintenance easier than retaining markup because a previous developer added it without explanation.
Common questions about structured data
Will all structured data create a rich result?
No. A vocabulary can describe more things than a search engine supports as visual features. Valid output and eligible content do not guarantee enhanced display.
Can JSON-LD replace readable content?
No. It supplements the page with machine-readable descriptions. People still need the visible explanation, and search markup should accurately represent what the page contains.

- Schema markup — Structured data describing entities and relationships in a recognised vocabulary. Markup should match the visible page and does not guarantee enhanced search results.
- Canonical URL — The preferred URL for a page when identical or substantially similar content is accessible through multiple addresses. A canonical link communicates a preference rather than forcing a redirect.
- WordPress — A content management system that can be extended through themes and plugins. A reliable implementation needs supported components, controlled access, updates and backups.
- Technical SEO — Improving the technical foundations of search access and understanding, such as crawlability, indexing signals, URL handling, rendering and performance.
