Schema Markup Checklist: Every Structured Data Type Your Site Needs in 2026

1. Organization Schema

Implement on your homepage. Include: name, url, logo, description, foundingDate, contactPoint, address, sameAs (links to all official social profiles). This establishes your brand entity in Google's Knowledge Graph and helps AI models identify your organization definitively.

2. WebSite Schema

Implement on your homepage alongside Organization. Include: name, url, potentialAction (SearchAction for site search). This tells search engines your site exists as a cohesive entity and enables sitelinks search boxes.

3. BreadcrumbList Schema

Implement on every page (except the homepage). Include the full breadcrumb path from homepage to current page. This helps search engines and AI models understand your site's hierarchy and improves navigation display in search results.

4. WebPage Schema

Implement on every page. Include: name, description, url, datePublished, dateModified, isPartOf (pointing to the WebSite). This provides page-level metadata that AI models use to assess relevance and freshness.

5. Article / BlogPosting Schema

Implement on every blog post and article. Include: headline, datePublished, dateModified, author (as Person with link to author page), publisher (as Organization), description, image, mainEntityOfPage. This is essential for AI citation attribution.

6. Person Schema (Author)

Create an author page for each content creator with Person schema. Include: name, jobTitle, worksFor, url, sameAs (LinkedIn, Twitter), description, image. Named, credentialed authors get cited more frequently by AI models.

7. FAQPage Schema

Implement on pages with FAQ sections. Include: mainEntity array with Question/Answer pairs. Each question needs name (the question text) and acceptedAnswer with text (the answer). This directly feeds both Google FAQ rich results and AI question-answer extraction.

8. HowTo Schema

Implement on tutorial and how-to content. Include: name, description, step array with HowToStep (name, text, optional image). This structures your instructional content for rich results and makes step-by-step processes easy for AI to cite.

9. LocalBusiness Schema

Implement on your contact or location page if you serve local customers. Include: name, address, telephone, openingHours, geo (latitude/longitude), priceRange, areaServed. This is critical for local AI search visibility.

10. Service Schema

Implement on each service page. Include: name, description, provider (your Organization), areaServed, serviceType, offers (if applicable). This helps AI models understand what you offer and recommend you for relevant queries.

11. ProfessionalService Schema

For professional service firms (agencies, law firms, consultancies), use ProfessionalService as a more specific type of LocalBusiness. Include all LocalBusiness fields plus specific professional credentials and areas of expertise.

12. Product Schema

Implement on every product page. Include: name, description, image, brand, sku, offers (price, availability, priceCurrency), aggregateRating, review. This is essential for Google Shopping results and AI shopping recommendations.

13. Review and AggregateRating Schema

Implement on pages with reviews or ratings. Include: reviewRating, author, datePublished, reviewBody for individual reviews. For aggregate, include ratingValue, reviewCount, bestRating. AI shopping assistants heavily weight review data.

14. Offer Schema

Implement within Product schema. Include: price, priceCurrency, availability (InStock, OutOfStock, PreOrder), priceValidUntil, seller. Accurate pricing data helps AI models provide correct recommendations and comparison information.

15. SpeakableSpecification Schema

Identify the 2-3 most important paragraphs on each page that best summarize the key information. Wrap them with Speakable schema to signal to AI and voice assistants that these sections are ideal for citation and readback.

16. VideoObject Schema

Implement on pages with embedded videos. Include: name, description, thumbnailUrl, uploadDate, duration, contentUrl or embedUrl. Video schema helps with Google Video results and gives AI models multimedia context about your content.

17. Event Schema

Implement on event pages, webinar pages, or conference listings. Include: name, startDate, endDate, location (virtual or physical), description, organizer, offers. AI models use event data to answer queries about upcoming industry events.

18. Course Schema

If you offer educational content, courses, or certifications, implement Course schema. Include: name, description, provider, coursePrerequisites, educationalLevel. This helps AI models recommend your educational offerings.

19. ItemList Schema

For listicle content, category pages, or "best of" articles, implement ItemList schema. Include: itemListElement array with ListItem (position, name, url). This structures your list content for carousel-style rich results and AI list extraction.

20. SameAs and Mentions Schema

Use sameAs properties to link your Organization to all official profiles (LinkedIn, Twitter, Facebook, Crunchbase, Wikipedia). Use mentions markup to link to entities referenced in your content. This builds the entity graph that AI models use to understand relationships.
