sameAs schema for a small business: which profiles to link and how to check them

Short answer: sameAs is a list of web addresses inside your business's structured data that says "these other pages are also us". Google's documentation lists it as a recommended property for an Organization, not a required one, and describes it as the URL of a page on another website with more information about your organization, for example your profile on a social media or review site. Put it on your home page or About page, link only pages you control or that clearly describe you, and open every link yourself before you publish.

Why a small business should care

A search engine or an AI assistant reading your site sees a name. It has to decide whether that name is the same as the company on LinkedIn, the listing on a directory and the developer page in an app store. A sameAs list answers that question in writing, so nobody has to guess. It will not move you up a results page by itself, and neither Google nor the AI companies promise anything for it. What it does is remove one reason for getting you mixed up with someone else.

That matters most when your name is common or close to someone else's. I found this out on my own handle: instagram.com/devmarde is a stranger's account with about a thousand followers, and ours is @hey.devmarde. On 8 October our YouTube channel was linking to the stranger's profile. A short, checked list of your own profiles is the cure for that kind of mistake.

What Google says

• It is recommended, not required. The Organization documentation says there are no required properties, and sameAs sits under the recommended ones.
• It takes URLs of other pages about you. You can give several. Google's example is a profile page on a social media or review site.
• It belongs on one page. Google suggests your home page or a single page that describes your organization, such as About. It does not need to be on every page.
• schema.org's own definition is a URL of a reference web page that unambiguously indicates the item's identity, which is why vague pages make poor entries.

Which profiles to put in it

1. Your official social profiles. LinkedIn company page, X, Instagram, YouTube, Facebook page, Pinterest, TikTok. Only the ones you actually run.
2. Review and directory listings that carry your name. A Clutch or Google Business Profile page, once it exists and is yours.
3. Your company register entry. In the UK that is the Companies House page for your company number. It is a page on another website that names your business, which is what the property asks for.
4. An app store developer page, if you publish apps.
5. A Wikidata item, only if one exists for your business and says what you are. Do not create one to fill the list.

Leave out the personal profiles of the people who work for you. Those belong in the markup for each person, on their own team page, so an assistant does not read "the founder" and "the company" as one entity. That one is our own practice, not a Google rule. Also leave out link-in-bio pages, pages written about you by people you do not control, and anything you have not opened this week.

A copyable example

<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "Organization",
  "name": "Your Business",
  "url": "https://www.yourbusiness.com/",
  "logo": "https://www.yourbusiness.com/logo.png",
  "sameAs": [
    "https://www.linkedin.com/company/your-business",
    "https://www.instagram.com/your.handle/",
    "https://www.youtube.com/@your.handle",
    "https://www.facebook.com/your.page",
    "https://find-and-update.company-information.service.gov.uk/company/00000000"
  ]
}
</script>

Replace each line with your own address, and delete the ones you do not have. Put the block on your home page or About page. If you use a plugin, see whether it already writes an Organization block, because two blocks that disagree are worse than none. Our schema generator writes the block for you.

Check every link before you ship it

1. Open it in a private window. It should load without a login and show your business name.
2. Read the name and the logo. A handle that looks like yours is not yours until the page says so.
3. Check who it belongs to. If it follows a stranger, remove it. This is how the YouTube mistake above happened.
4. Check that it links back. Your LinkedIn and Instagram bios should point at your site, so the connection goes both ways.
5. Use one spelling of your name across the markup, the profiles and the site footer.

How to test the markup

Paste your page address into the Schema Markup Validator, which lists every node it finds whether or not Google turns it into a rich result. Or view the page source and search for application/ld+json. Our free Crawl Audit also looks for it, and the sameAs check explainer shows what a pass looks like.

What it will not do

It does not create a knowledge panel, raise your ranking or make an assistant mention you. We have no result of ours to show for it yet: devmarde.com has had impressions in Google since 16 September, and we have not run an AI-answer baseline, so we do not claim a change from it. The reason to do it is that it is cheap and it states plainly who you are. For how it fits with the rest of the markup, see the complete guide to AI search optimization and the guide on review schema for service businesses.

What we do on devmarde.com

Our Organization markup lists 12 addresses: LinkedIn, X, Instagram (@hey.devmarde), TikTok, Pinterest, YouTube, our Companies House entry, our Wikidata item, our Clutch and The Manifest listings, our Google Play developer page and our Facebook page. Each one was opened and checked to name DevMarDe before it went in.

Questions people ask

Is sameAs required for local business or organization schema?

No. Google's documentation lists no required properties for Organization, and sameAs is one of the recommended ones.

How many sameAs links should I add?

As many as are true and checkable. Google says you can provide multiple URLs. Five good ones are better than fifteen where some are dead or belong to someone else.

Should I put my personal LinkedIn in my company's sameAs?

We would not. A personal profile describes a person. Put it in the markup for that person on their own page, and keep the company's list to pages about the company.

Does sameAs help me show up in ChatGPT or Perplexity?

Nobody publishes a promise that it does. It states your identity clearly, which cannot hurt, but we have not measured any effect on AI answers.

What if a profile link goes to the wrong account?

Remove it from the markup and from every page that links to it, then fix the profile itself. Check again after a few days, because search engines keep old data for a while.
