How to Structure JSON-LD

JSON-LD describes a page to machines. Valid, honest structured data helps representation; invalid or fake markup can be ignored or counterproductive.

The issue

Markup has JSON syntax errors, missing @context/@type, or fabricated review/rating/price data.

Why it matters

Broken JSON-LD is dropped; fake ratings/pricing violate guidelines and erode trust.

Common mistakes

  • Invalid JSON (trailing commas, unescaped quotes).
  • Missing @context or @type.
  • Inventing aggregateRating/offers that don't exist.
  • Multiple unrelated objects without @graph.

Practical recommendations

  • Validate JSON first; one @context per document.
  • Pick a specific, accurate @type (Article, TechArticle, Organization, BreadcrumbList, FAQPage).
  • Use @graph for multiple related entities.
  • Never fabricate ratings, reviews, or pricing.

FAQ

Is this guaranteed to improve rankings?

No. This is technical hygiene that helps machines parse and trust pages; no ranking outcome is guaranteed.

Do I need a backend?

No. The linked tools run entirely in your browser; nothing is uploaded.

How often should I check?

After every significant deploy, and periodically as content changes.
