Quick Definition #
Structured data is a standardised way to describe information on a webpage. Schema.org provides shared vocabulary for entities and properties. Search engines may use eligible markup to understand content and display certain enhanced results.
Common Schema Types #
- Organization: Describes an organisation.
- LocalBusiness: Describes an eligible local business.
- Article: Describes an article and details such as headline and dates.
- BreadcrumbList: Describes a breadcrumb trail.
- Product: Describes eligible product pages.
- Event: Describes a real event when requirements are met.
Choose a type that accurately represents the visible page content. Eligibility rules and supported features can change.
JSON-LD and Implementation #
JSON-LD is a common format for embedding structured data. The markup must be accurate and should not include fabricated, misleading or hidden information. CMS plugins may generate schema, but their output still needs review.
Implementation Workflow #
- Identify the page purpose and suitable schema type.
- Review current search engine documentation and eligibility requirements.
- Add accurate properties based on visible content.
- Validate the markup with an appropriate testing tool.
- Monitor Search Console reports where available.
- Recheck after content or template changes.
Example #
An educational article may use Article markup with its real headline, author and publication date. Product markup would be inappropriate for a page that does not represent a product, even if the code validates.
Structured Data and Rankings #
Structured data can clarify what a page represents and may make it eligible for certain rich results. It does not guarantee an enhanced result or provide a ranking shortcut.
Common Mistakes #
- Marking up content users cannot see.
- Using a schema type that does not fit the page.
- Adding fabricated reviews, ratings or event details.
- Assuming valid syntax guarantees rich results.
- Leaving stale markup after content changes.
Key Takeaway #
Use structured data to describe real content accurately. Validate it, maintain it and treat rich results as eligibility—not a promise.
FAQs #
Is Schema.org the same as JSON-LD? #
No. Schema.org supplies the vocabulary; JSON-LD is a format for expressing structured data.
Does schema guarantee higher rankings? #
No. It may help search engines interpret content and determine eligibility for certain features, but it does not guarantee rankings.
