Why this signal matters for Google
A certification is the only proof of expertise that can expire. That is its strength and its weakness. A degree records training you completed once and for all. A certification says an outside body checked a skill on a given date, usually for a few years only. So you are publishing a dated claim your reader can check. While it holds, it is a strong signal. Expired two years ago and still sitting in your footer, it is a negative one.
Google has human evaluators grade pages, guided by a public manual: the Quality Rater Guidelines, or QRG. Section 2.5.2 asks them to work out who is responsible for the website and who created the content on the page. That is exactly what a certification does: it qualifies that person or that company. Section 3.4 judges expertise on real skill for the topic at hand. And section 3.3.4 counts peer validation and educational degrees among the evidence of a good reputation. A certification runs the same way: someone independent vouches for you. A badge whose issuer you cannot name ticks none of those boxes. The place to show it is your About page, next to the name of the person it belongs to.
On a YMYL topic, meaning a page that touches health, money or law, the certification stops being decorative. Section 3.4.1 says a high level of expertise may be required for such a page to be trustworthy, and section 5.1 rates as Low quality a page whose creator lacks the skill the topic demands. In trades governed by law, registration with a professional body or an official licence is often the only certification that really counts. A commercial label does not replace it, it sits on top of it.
For AI systems, a certification is a detail they can confirm elsewhere. When AI Overviews, ChatGPT or Perplexity decide who to cite, they look for things that check out on another site: a title tied to a known issuer, a public verification record, a professional profile that says the same thing. A certification written out in plain text and attached to a marked-up author entity helps them connect your content to a real, qualified person. A badge that exists only as an image, with no text and no link, stays invisible to them: they do not read logos.
The NeuroEEAT scoring grid (0-10)
Assess what your certifications actually prove, from decorative logo to proof anyone can check.
| Score | Description | Concrete indicators |
|---|---|---|
| 0-2 | Invisible | No certification mentioned even though your field has recognized ones. Nothing lets anyone place your competence or the company's, which is what section 2.5.2 looks for. |
| 3-4 | Decorative badge | A logo in the footer, with no full title, no legible issuer, no date. The visitor sees an image, not something they can check. |
| 5-6 | Stated in plain text | Title, issuer and year are written out in a bio or About page, but no link lets anyone verify them or find out whether the certification is still valid. |
| 7-8 | Verifiable and dated | Each certification links to the issuer's registry, shows its award date and its end date, and makes clear who holds it. |
| 9-10 | Maintained and structured | Certifications verifiable, current, tied to an author marked up in the code, identical on your professional profiles, with renewal tracking written down. |
How to audit it on your site
Five checks to find out whether your certifications prove anything or merely decorate your pages.
- 01
Inventory what is on display
List every badge, logo and certification mention on the site, with the page and the exact spot. A badge you can neither date nor trace back to an issuer is already a finding.
- 02
Check validity
For each one, find the award date and the end date, then check the status in the issuer's registry. An expired certification presented as active is not a rounding error, it is false information on your own page.
- 03
Test the one-click check
Ask whether a stranger could confirm the certification without emailing you. A badge image with no link to the holder's record at the issuer cannot be verified: it asks the reader to take your word for it.
- 04
Identify who holds what
Separate what certifies the company from what certifies the author of the page. Agency partner status does not qualify the writer of an article, and section 2.5.2 asks you to keep those two responsibilities apart.
- 05
Weigh the link to the topic
Match each certification against the subject and its level of risk. On a page about health or money, section 3.4.1 expects skill that matches the advice given, not an impressive but unrelated title.
How to activate or improve it
Three levels to move a certification from decorative logo to proof that really works for your credibility.
Make the certification legible
- Replace every standalone logo with a plain line: exact title, issuing body, year awarded.
- Spell out the issuer's full name before its acronym, for a reader who does not know the field.
- Put certifications in the author bio, as close as possible to the content they qualify.
- Remove without delay any certification that has expired or that you can no longer trace.
Make the certification verifiable
- Link each certification to its public record at the issuer: official registry, badge platform, professional body directory.
- Show the end date when the certification has one, instead of implying it lasts forever.
- Visually separate company certifications from those held by the people who sign the content.
- Align the wording with your LinkedIn profile and your other public profiles, word for word.
- On sensitive pages, put the certification right next to the advice it covers so the reader makes the link.
Structure and maintain
- Mark up the author in JSON-LD (a Person block in the code, invisible to readers) and connect the certifications through sameAs to their verification records.
- Fill hasCredential where the schema vocabulary supports it, without overloading the markup.
- Keep a sheet of end dates and start the renewal before the deadline, not after.
- Write into your editorial policy who checks the certifications on display, and how often.
- Get your certifications cited by third parties: the issuer's directory, partner pages, interviews.
5 common mistakes to avoid
Sector specifics
Practitioner and health advice site
The advice affects the reader's health. Section 3.4.1 expects real competence here: licence number, registration with the professional body or clinical certification, shown, dated and tied to the person who signs the article rather than to the brand alone. A generic wellness certificate does not stand in for that.
Advisory, brokerage and asset management
Here a mistake hits the reader's money. What weighs most is registration with the relevant regulator and the number that lets anyone check it in the public registry. Professional certifications complete that base, they do not replace it, and their validity dates must stay visible.
Certified agency or vendor
Vendor partner programs, Google, AWS, HubSpot and equivalents, issue badges you can verify in an official directory: link to that directory instead of showing the image alone. Say who on the team holds the certification too: a company badge says nothing about the consultant assigned to the project.
Regulated trade and quality label
For an electrician, a plumber or a contractor, the trade qualification and the insurance are the certifications clients actually look for. Show the title, the number and the link to the issuing body's directory, on the service page concerned rather than on an isolated About page.
Signals to activate in parallel
A certification pays off when it is connected to the signals that identify and qualify the person holding it:
FAQ
Where should you display certifications on website pages?
As close as possible to the content they qualify. A certification stranded on the About page does almost nothing: put it in the author bio at the foot of the article and on the relevant service page. The global footer suits company certifications, provided they stay clickable and dated.
Should you remove an expired certification?
Yes, straight away. An expired certification presented as active is false information on your own site, and it is the first detail a doubtful reader or an evaluator checks. Remove it, or state clearly the period it covered if it still has historical value.
Is a badge logo enough as proof?
No. An image cannot be verified and engines cannot read it. The useful minimum is the title in text, the issuer's full name, the year, and a link to the holder's record. The logo then becomes a visual cue, not the proof itself.
Do company certifications count for the author?
No, and blurring the two weakens both. Certified partner status qualifies the company; it says nothing about the skill of the person writing. Show them separately, stating clearly who holds what, as section 2.5.2 asks.
How many certifications should you show?
Two or three useful ones beat ten stacked up. An off-topic certification dilutes the others and reads as decoration. The filter is simple: does this certification qualify the person for the specific subject of this page?
