How to Showcase Company Credentials Online So Machines Can Read Them
2026-04-28 · 13 min read
You have the credentials. The ISO certificate is framed on the wall. Your engineers hold BNSP certifications. Your director sits on an industry committee. The question is not whether these credentials exist. The question is whether machines can find them, parse them, and verify them without a human having to scan a PDF and interpret what it means.
Most company credentials are invisible to machines. They live in proposal documents, certificate binders, and LinkedIn sections that are not structured for knowledge graph ingestion. The gap between "having credentials" and "having machine-readable credentials" is the gap between being qualified and being discoverable.
This essay is a practical guide. Where to publish credentials. How to structure them. Which platforms matter for machine-readability. And the specific JSON-LD patterns that make credentials parseable by Google, AI systems, and due diligence tools.
The Credential-to-Platform Mapping
Different credential types belong on different platforms. The goal is coverage: ensuring that each credential appears on at least two platforms (your own domain plus one independent source) in machine-readable format. This creates the corroboration that knowledge graphs require to treat a credential as verified rather than claimed.

The green-highlighted platforms (Company Website and ORCID) are the two you have most control over and should build first. The certification body registry is highlighted separately because it is the highest-authority independent source but you have limited control over how it presents your data.
Your Website: The Credential Hub
Your company website is the only platform where you control both the human-readable and machine-readable presentation of your credentials. This makes it the foundation of credential visibility.
Create a dedicated credentials page. Not a paragraph buried in your about page. A standalone page that lists every credential your company and key personnel hold. For each credential, include: credential name (in both original language and English if non-English), issuing body with full official name, certificate or license number, issue date, expiration date (if applicable), scope or description of what the credential certifies, and verification URL if the issuing body has an online registry.
Implement JSON-LD Certification schema. This is the machine-readable layer. As I covered in strategic schema markup, structured data is what transforms a webpage from a document that humans read into data that machines can process.
The Certification schema implementation connects three entities: the credential holder (your company or person), the credential itself, and the issuing body. Each of these should be represented with their own entity properties. The issuing body should include its @type as Organization, its name, and its URL. This creates a chain of entity connections that knowledge graphs can trace and verify.
As explored in Person schema implementation, the key is consistency. The company name in your Organization schema must exactly match the company name in your Certification schema. The issuing body name must exactly match how the issuing body identifies itself. Mismatches create ambiguity that weakens rather than strengthens the signal.
LinkedIn: The Professional Verification Layer
LinkedIn is not just a networking platform. It is a structured data source that Google and AI systems index heavily. Your LinkedIn company page and personal profiles are entity surfaces.
For company credentials, use the LinkedIn company page's "About" section to list key certifications. This is limited in structure, but the text content gets indexed. More importantly, individual employee profiles on LinkedIn have a dedicated "Licenses & Certifications" section that generates structured data. When your engineers list their certifications on their LinkedIn profiles with the company listed as their current employer, this creates a Person-Credential-Organization chain that knowledge graphs can process.
As I detailed in linking employee credentials to company entity, this compound effect works best when multiple employees' credentials all point back to the same company entity. Five engineers at your company, each listing their professional certifications on LinkedIn, creates five independent verification pathways for the company's talent claims.
ORCID: The Persistent Identifier
ORCID profiles are underused outside academia, but they are powerful credential platforms for any professional. An ORCID profile can list employment (connecting Person to Organization), qualifications (connecting Person to Credential), and works (connecting Person to publications and projects).
The key advantage of ORCID is that it provides a persistent, globally unique identifier. When your ORCID ID appears in a Zenodo publication, on your company website's Person schema, and on your LinkedIn profile, knowledge graphs can unambiguously connect all of these to the same Person entity. This eliminates the name-collision problem that plagues common names.
As discussed in board positions as entity signals, institutional affiliations documented in ORCID create structured links between your Person entity and the institutions you belong to. Each link is an independently verifiable connection.
Google Business Profile
Google Business Profile is a direct input to Google's Knowledge Graph. For companies with physical locations, it is one of the strongest entity signals available.
The profile supports a description field where you should mention key certifications. It supports categories that indicate your business type. And most importantly, it creates a verified Organization entity in Google's system that other structured data can reference.
The credential documentation on your website should reference the same company name, address, and category as your Google Business Profile. This consistency tells Google that the company entity on your website and the company entity in Google Business Profile are the same entity. That unification strengthens both.
Industry Directories and Certification Body Registries
These are the independent corroboration sources. You have less control here, but they carry more weight precisely because you do not control them.
If your certification body publishes an online registry (as most ISO certification bodies do through their accreditation body's database), ensure your listing is accurate. Check that the company name, certificate number, and scope match what you have on your website. Discrepancies between your self-published data and the certification body's data create red flags rather than verification signals.
Industry directories (industry associations, trade groups, chamber of commerce member directories) are another independent corroboration layer. As I covered in why certification matters, the key is that these sources are independent. A knowledge graph weighs information from a source you do not control more heavily than information from a source you do control.
The Implementation Sequence
If you are starting from zero, here is the practical order.
Phase 1: Your domain (Week 1-2). Create the credentials page. Implement Certification schema for each credential. Ensure Organization schema is complete and consistent. This is the foundation everything else builds on.
Phase 2: Personal profiles (Week 2-3). Set up or update ORCID profiles for the director and key personnel. Update LinkedIn profiles with accurate certification listings. Ensure the company affiliation is consistent across all profiles.
Phase 3: External platforms (Week 3-4). Claim or update Google Business Profile. Check certification body registries for accuracy. Submit to relevant industry directories. Request listing updates from any institution where your company or personnel hold positions.
Phase 4: Cross-referencing (Month 2). Add sameAs properties to your Organization schema pointing to your Google Business Profile, LinkedIn company page, and any industry directory listings. This explicitly tells knowledge graphs that all of these profiles represent the same entity. As covered in Person schema, the same principle applies to personal profiles.
Phase 5: Ongoing maintenance. Credentials expire and renew. New certifications get added. Staff changes require profile updates. Build a quarterly review into your operations to ensure credential data stays current across all platforms.
Common Mistakes
Inconsistent company names. "PT Arsindo Integrasi Pompa" on the website, "Arsindo" on LinkedIn, "PT. Arsindo" on the Google Business Profile. Each variation creates ambiguity. Pick the exact legal name and use it everywhere.
Missing certificate numbers. Listing "ISO 9001:2015 Certified" without the certificate number is a claim. Listing "ISO 9001:2015, Certificate No. QSC-12345, issued by [Body Name], valid through 2027-12-31" is verifiable data. Include the details.
Expired credential data. Structured data with expired validity dates tells knowledge graphs that your certification has lapsed. If you have renewed, update the dates. If you have not renewed, remove the claim. Inaccurate structured data is worse than no structured data.
No independent sources. If your credentials appear only on surfaces you control (website, LinkedIn, ORCID), they are self-published claims. The knowledge graph treats them as such. You need at least one independent source (certification body registry, industry directory, institutional website) confirming each credential for it to count as verified.
The entity infrastructure work I do with companies focuses heavily on this credential-to-platform mapping. And the Entity Infrastructure course includes the specific JSON-LD templates, platform configuration guides, and audit checklists for the complete implementation.
The Machine-Readability Test
Here is a simple test for whether your credentials are machine-readable. Go to Google's Rich Results Test tool. Enter your company website URL. Look at the structured data Google detects. If your certifications do not appear in the parsed output, they are invisible to Google's knowledge graph processing.
Then ask ChatGPT or Perplexity: "What certifications does [your company name] hold?" If the AI cannot answer accurately, your credentials are invisible to AI systems.
Both tests should return your credentials accurately and completely. If either fails, you have a visibility gap that is costing you consideration in every AI-mediated procurement process and every digital due diligence check.
The credentials are real. Make them readable.
Frequently Asked Questions
Can I put all credentials in a single JSON-LD block or do I need separate blocks?
You can include multiple credentials in a single JSON-LD block by using an array within the Organization or Person entity. Each credential should be a separate Certification object within the hasCredential array. This keeps the data organized and allows knowledge graphs to process all credentials as properties of the same entity. A single well-structured block is cleaner than multiple separate blocks.
How do I handle credentials where the issuing body no longer exists?
Document the credential with the original issuing body name and add context about the succession. If the body was absorbed into another organization, reference the successor. If it simply ceased to exist, document the credential with the original name and note the dates. The historical credential still contributes to entity history, even if the issuing body is no longer active. Do not remove the credential. Historical credentials show track record depth.
Should subcontractor or partner certifications be listed on our company profile?
No. Only list credentials held by the company itself or by individuals employed by the company. Listing partner or subcontractor certifications as if they are your own is misrepresentation and can create entity confusion in knowledge graphs. If you work with certified partners, document the partnership separately. Reference the partner as an affiliated entity with their own credentials, keeping the entity boundaries clear.
What if Google's Rich Results Test does not show my Certification schema?
First, verify your JSON-LD syntax is valid using a JSON-LD validator. Common errors include missing commas, unclosed brackets, or invalid property names. Second, check that the schema is in the page source (not dynamically loaded by JavaScript after page load). Third, note that Certification is a relatively new Schema.org type and Google may not display it in Rich Results even if they process it for Knowledge Graph purposes. The absence from Rich Results does not necessarily mean the data is being ignored by the Knowledge Graph.
How many platforms should each credential appear on?
Minimum two: your own domain and one independent source. Ideal is three or more: your domain, a personal profile (ORCID or LinkedIn), and an independent source (certification body registry or industry directory). Each additional platform creates another verification node. But accuracy matters more than quantity. One credential accurately documented on three platforms is better than one credential inconsistently documented on seven platforms.
