Structured-data FAQ
The questions we field most often from first-timers. The articles above go deeper on each.
- 01Structured data, JSON-LD, schema — same thing?
- Used interchangeably in practice. Strictly: structured data is the umbrella concept, schema.org is the shared vocabulary, JSON-LD is the syntax for embedding it. Google officially prefers JSON-LD, so the three labels point to the same thing in most conversations.
- 02Will JSON-LD raise my Google ranking?
- Not as a direct ranking signal. What it does: lets you show up as a richer SERP card at the same rank, and dramatically improves the odds that AI search (ChatGPT, Perplexity, Google AI Overview) cites you accurately. CTR and visibility go up downstream.
- 03Can I put more than one type on a single page?
- Yes. A product page can carry Product + BreadcrumbList + Organization without conflict. Best practice is either a single @graph bundle, or two or three side-by-side <script type="application/ld+json"> tags.
- 04How do I confirm it was applied correctly?
- Drop your URL into Google's Rich Results Test — detected types, errors, and a live preview, all in one screen.
- 05I use a WordPress SEO plugin (Yoast / Rank Math). Do I still need this?
- Plugins cover different types than custom JSON-LD. Basics like Article and WebPage are usually handled; FAQPage, Event, Recipe, Course, HowTo — types that vary page-to-page — you add yourself. Run the diagnose tool, fill the gaps.
- 06Is there a penalty for getting it wrong?
- Plain errors (missing required fields, etc.) are silently ignored. The risk is misrepresentation — claiming a price your page doesn't show, for example. That gets you dropped from rich results and, if repeated, erodes site trust. Stay consistent with the visible content and you're safe.
- 07Does AI search (ChatGPT, Perplexity) actually read this?
- Yes. Recent published research and field experiments confirm SearchGPT, Perplexity, and Google AI Overview all weight JSON-LD heavily when grounding answers. LocalBusiness and Organization in particular sharply improve citation accuracy.
