sameAs Schema: Connecting Your Brand Across the Web
sameAs explicitly tells engines your scattered profiles belong to one organisation. Why that consolidation drives entity confidence, and which URLs to include.
The sameAs property in Organization schema does one simple, valuable job: it explicitly tells search engines and AI systems that the profiles scattered across the web — your LinkedIn page, your X account, your Crunchbase listing, your review platform profile — all belong to the same organisation as your website. Without it, engines have to infer those connections from names and context. With it, you’ve stated the relationship in machine-readable form, strengthening the entity understanding AI recommendations depend on.
Key takeaway
- sameAs explicitly links your official profiles to your organisation, so engines don’t have to infer the connection.
- It consolidates scattered signals into one entity, which is what lets engines recommend you confidently.
- List only official profiles you control or that authoritatively describe you — accuracy matters more than quantity.
What the property does
sameAs is a property within Organization schema that takes a list of URLs, each pointing to another authoritative page about the same entity. It’s a statement of identity: this website, that LinkedIn company page and that Wikidata item all refer to one organisation. Search engines and AI systems that read your structured data can then treat evidence from all those sources as evidence about a single entity, rather than as separate signals about possibly-different things with similar names.
Stated, not inferred
sameAs converts a guess into a declaration. Instead of engines inferring that scattered profiles belong to you, you tell them in machine-readable form — removing ambiguity from the entity picture.

Why consolidation matters
AI engines only recommend brands they can identify confidently. Every corroborating source that describes your business — a LinkedIn page, a review profile, a directory listing — adds to that confidence, but only if the engine connects it to you. Fragmented signals across sources it can’t confidently link produce a fuzzy picture; consolidated signals produce a defined entity. sameAs is one of the cheapest ways to help that consolidation, because it’s a single markup addition that ties everything together.
What to include
- Official social profiles. LinkedIn, X, YouTube, Instagram, Facebook — whichever you genuinely maintain.
- Business and industry listings. Crunchbase, relevant industry directories, and any authoritative registry you appear in.
- Review platform profiles. Your claimed profiles on the platforms that matter in your category.
- Wikidata or Wikipedia, if you have them. These are particularly strong identity anchors.
What to leave out: profiles you don’t control, abandoned accounts, pages about a different entity with a similar name, and anything you can’t stand behind. A wrong sameAs link actively confuses the entity picture rather than clarifying it.
Keep it accurate and current
sameAs only helps while the links are correct. Dead profiles, changed URLs and abandoned accounts turn a clarifying signal into a misleading one, so review the list whenever your profiles change — and remember that consistency of your business details across those profiles matters just as much as linking them. There’s little value in connecting five profiles that give three different addresses. Fix the underlying consistency first, then use sameAs to tie the consistent picture together.
Frequently asked questions
What is sameAs schema?
sameAs is a property in Organization schema listing URLs of other authoritative pages about the same entity — your LinkedIn page, review profiles, directory listings, Wikidata item. It explicitly states that these all refer to one organisation, so engines can treat evidence from each as evidence about a single, defined entity rather than as unconnected signals.
Does sameAs help AI visibility?
Yes, by supporting entity confidence. AI engines only recommend brands they can identify confidently, and consolidating scattered corroborating sources into one recognised entity strengthens that identification. sameAs is a cheap way to help — a single markup addition that ties your official profiles to your organisation explicitly rather than leaving engines to infer.
Which URLs should I include in sameAs?
Official social profiles you genuinely maintain, business and industry listings like Crunchbase or relevant directories, claimed review platform profiles, and Wikidata or Wikipedia entries if you have them. Exclude profiles you don’t control, abandoned accounts and anything referring to a different entity — a wrong link confuses the entity picture rather than clarifying it.
Do I need to maintain the sameAs list?
Yes — review it whenever your profiles change, since dead links and outdated URLs turn a clarifying signal into a misleading one. Equally important is consistency of your business details across those linked profiles; there’s little value in connecting five profiles showing three different addresses. Fix consistency first, then link the consistent picture together.
The bottom line
sameAs turns an inference into a declaration, telling engines directly that your scattered official profiles belong to one organisation. That consolidation is what lets AI engines identify — and therefore recommend — you confidently. List only accurate, official, maintained profiles, keep the list current, and make sure the details across those profiles actually agree.
