Structured data is a label system. It tells machines "this is a business, this is its address, this is a service it offers, and this is a question with its answer." Search engines and AI assistants use it to understand entities and relationships faster than they can infer them from prose.
The short list worth adding
| Type | Where | What it communicates |
|---|---|---|
| Organization or LocalBusiness | Home page and contact page | Name, logo, contact details, social profiles |
| Service | Each service page | What you offer, where, for whom |
| FAQPage | Pages with visible questions and answers | Question and answer pairs |
| Article or BlogPosting | Each article | Author, dates, headline, publisher |
| BreadcrumbList | Every inner page | Where the page sits on the site |
| WebSite | Home page | Site name and search action if you have one |
Rules that keep you out of trouble
- Mark up only what is visible. Schema that describes content users cannot see violates guidelines.
- Keep details consistent. Name, address and phone should match your site, directory listings and profiles.
- Use valid values. For service areas, name real countries, regions or cities rather than invented codes.
- Do not fabricate reviews or ratings. Self-served review markup is a quick route to a manual action.
- Keep it updated. Old prices and dates erode trust.
Common mistakes on small business sites
- A LocalBusiness block with a virtual or mailbox address presented as a storefront.
- FAQPage markup for questions that appear nowhere on the page.
- Duplicate Organization blocks with conflicting details across templates.
- Missing author and date on articles, which weakens trust signals.
- Non-standard values in service area fields.
Example structure
Keep one canonical Organization entity with a stable identifier on the home page, then reference it from other pages instead of redefining it. Link your social profiles using the sameAs property. On an article, reference the author entity and the publisher. This builds a coherent graph rather than a pile of unrelated blocks.
How to test
Run each template through Google's Rich Results Test and the Schema.org validator before release. Check Search Console's enhancement reports after launch. Re-test whenever a template changes.
Next.js implementation notes
Generate JSON-LD on the server in a reusable component, serialize it safely and render it in the page output so crawlers that do not run JavaScript still see it. Build schema from the same data that renders the page to prevent drift.
Frequently asked questions
Does schema markup improve rankings?
Not directly. It helps search engines and AI assistants understand your content and can enable rich results, which may improve click-through. Content quality and authority still drive rankings.
Which schema types does a service business need?
Organization or LocalBusiness, Service, FAQPage where questions are visible, Article for blog posts and BreadcrumbList for inner pages.
Can schema markup hurt my site?
Yes, if it misrepresents the page, invents reviews or conflicts with visible content. Invalid or misleading markup can lead to lost rich results or manual actions.
