sameAs (schema property)

How sameAs works in JSON-LD

{
  "@context": "https://schema.org",
  "@type": "Organization",
  "@id": "https://yourdomain.com/#organization",
  "name": "Your Brand",
  "sameAs": [
    "https://www.wikidata.org/wiki/Q12345",
    "https://en.wikipedia.org/wiki/Your_Brand",
    "https://www.linkedin.com/company/your-brand/",
    "https://twitter.com/yourbrand",
    "https://github.com/yourbrand",
    "https://www.crunchbase.com/organization/your-brand"
  ]
}

sameAs takes an array of URLs. Each URL should resolve to an authoritative profile / page representing the same entity.

Why sameAs matters for AI search

When ChatGPT, Claude, Perplexity, or Gemini need to disambiguate which “X” the user is asking about, the entity graph (Organization + sameAs links) provides the answer:

• Without sameAs: the model guesses based on context, might conflate your brand with a similarly-named one
• With sameAs: the model has a graph of authoritative identifiers and can confidently attribute facts

The sameAs property is the cheapest, highest-impact AI-search infrastructure investment for most brands.

Required sameAs targets

For B2B brands, prioritize in this order:

1. Wikidata Q-entity (if you have one, see Wikidata)
2. Wikipedia (if eligible, long-term, but worth pursuing)
3. LinkedIn company page
4. Twitter / X profile (if active)
5. GitHub organization (for developer-focused brands)
6. Crunchbase profile
7. Bloomberg profile (for public or PR-active brands)

For local businesses, add:

• Google Business Profile URL
• Yelp profile
• Industry-specific directory profiles

Common mistakes

• Linking to your own site’s pages, sameAs is for EXTERNAL representations, not internal pages
• Linking to outdated profiles, if your Twitter handle changed, update the sameAs
• Inconsistent profile names, the LinkedIn profile should match the Organization name in your schema
• Linking to vanity / personal profiles instead of organization profiles, link to the brand’s, not the founder’s, unless the founder IS the brand

The reciprocity question

Some brands ask: do external profiles need to link BACK to my site (reciprocal sameAs)?

The answer: not technically required, but helpful. When Wikipedia/Wikidata reference your website as the official URL, you’ve created a verifiable round-trip that increases AI confidence in the entity. Most sameAs targets (LinkedIn, GitHub, Crunchbase) have a website field, make sure your website is listed there.

Resocial perspective

Most schema implementations we audit have weak or empty sameAs arrays. Building a complete sameAs graph is one of the first things our Schema Markup service does. The work is straightforward; the AI citation rate impact is measurable within 3-6 months.
