Seven of the ten SEO certifications below are free, and the best place to start for most people is a pair of them: Google’s Analytics certification and either HubSpot’s or Semrush’s free SEO course. Add Ahrefs’ free certification once you use the tool regularly, and pay for a longer programme only when you want structured study over several months.
We checked every certification on this list in November 2026: the current name, the cost, how long it stays valid and where to take it. Several on the 2022 version of this post no longer exist in the form we described, and one major course has changed its focus to AI search. Prices and course names change often, so confirm on the provider’s page before you pay.
The 10 certifications at a glance
| Certification | Provider | Cost | Valid for | Best for |
|---|---|---|---|---|
| Google Analytics Certification | Google Skillshop | Free | 1 year | Everyone in SEO |
| Google Ads Search Certification | Google Skillshop | Free | 1 year | Understanding commercial intent |
| Search Advertising certification | Microsoft Advertising | Not listed on Microsoft’s page | Not stated | Bing and paid search basics |
| AEO Fundamentals | HubSpot Academy | Free | Not stated | SEO plus AI answer engines |
| Content Marketing Certification | HubSpot Academy | Free | Not stated | Content SEO roles |
| SEO Crash Course with Brian Dean | Semrush Academy | Free | 1 year | Beginners |
| Ahrefs Certification | Ahrefs | Free | 1 year | Anyone using Ahrefs |
| SEO for Beginners (and Yoast SEO Academy) | Yoast | Free, full academy with Premium | Not stated | WordPress users |
| SEO Specialization | UC Davis on Coursera | Paid subscription, financial aid available | Not stated | Structured university-style study |
| Google Digital Marketing & E-commerce Certificate | Google on Coursera | US$49 a month in the US, lower in some countries | Not stated | Career changers wanting a broad base |
The Google, Semrush and Ahrefs certificates expire after a year, which is a reasonable way to keep them current. Where a provider does not state a validity period, we say so rather than guess.
1. Google Analytics Certification
Every SEO role asks for analytics. Google’s certification tests your knowledge of Google Analytics 4, the version every client now uses. It is hosted on Skillshop alongside Google’s free Analytics Academy courses, which Google lists on its Analytics help page.
Google’s Skillshop help page says certifications are valid for one year, that you can recertify from 30 days before expiry, and that digital badges carry no fee.
2. Google Ads Search Certification
An SEO certificate from Google does not exist. Google Search Central publishes documentation, not exams. The closest Google credential that sharpens search skills is the Google Ads Search certification, because it teaches how Google values commercial intent and how paid and organic results compete for the same clicks.
Google lists Search, Display, Video, Shopping and Apps certifications, each valid for one year, taken through Skillshop (Google Ads Help).
3. Microsoft Advertising Search Advertising certification
Microsoft has renamed its programme since 2022. Its Learning Lab page now lists three certifications: Search Advertising, Display & Video (formerly Native & Display) and Retail (formerly Shopping). Passing all three earns Microsoft Advertising Certified Expert status.
The page does not state a fee or a validity period, so check both when you sign in. Paid search knowledge helps in any agency role, because clients ask how organic and paid traffic work together.
4. HubSpot AEO Fundamentals
HubSpot’s long-running free SEO certification course URL now leads to a course called AEO Fundamentals. It is free, takes about 2 hours 20 minutes over 7 lessons, and covers keyword research, E-E-A-T, structuring pages to be cited by AI answers, and measuring results in Search Console and GA4.
It is a good second certificate after Google Analytics because it treats classic SEO and AI answer engines as one job, which is how most clients now see it.
5. HubSpot Content Marketing Certification
If you want a content SEO role, this pairs well with the one above. The Content Marketing Certification course is free and runs about 8 hours 23 minutes across 14 lessons, ending in an exam.
6. Semrush SEO Crash Course with Brian Dean
Semrush Academy’s certification page lists the SEO Crash Course with Brian Dean as its main SEO certificate: 7 lessons, about 51 minutes, free. Certificates are valid for one year. You get three attempts at the final exam, then must wait a month to try again.
It is short, which makes it a sensible first step for complete beginners before they commit to longer courses.
7. Ahrefs Certification
The Ahrefs Certification is free. The exam has 67 questions, a one-hour limit and a 75% pass mark, and the certificate lasts one year. You need an Ahrefs account, but a free one works: free users get a blue certificate and paying customers a black one.
Prepare with the free How to Use Ahrefs course, which runs 63 lessons over about 3 hours 18 minutes. Employers who use Ahrefs value this one because it proves you can work the tool from day one.
8. Yoast SEO for Beginners and Yoast SEO Academy
Yoast offers five free courses with certificates, including SEO for Beginners and Structured Data for Beginners, according to its academy page. The rest of the academy, covering technical SEO, local SEO, ecommerce SEO, keyword research and AI for SEO, comes with the Yoast SEO Premium plan, listed at US$118.80 a year.
This is the most practical option if you will be working on WordPress sites, which many small business websites run on.
9. UC Davis SEO Specialization on Coursera
The Search Engine Optimization (SEO) Specialization from the University of California, Davis is five courses taking about two months at ten hours a week. Coursera shows over 278,000 learners enrolled. It is paid through a Coursera subscription, with financial aid available.
Choose it if you learn better with a syllabus and graded assignments than with short videos.
10. Google Digital Marketing & E-commerce Professional Certificate
This is the broadest option and the best fit for career changers. The Coursera page lists 8 courses, suggests about six months at ten hours a week, and charges US$49 a month in the US and Canada after a seven-day trial. Google’s own course page for Malaysia lists US$29 a month there, so check the price Coursera shows in your country.
SEO is one part of it, covered in the second course, alongside email, analytics and ecommerce. If you only want SEO, the options above are faster.
What changed since the 2022 list
We removed several entries because we could not confirm them as live, relevant certifications:
- Yext Certified Partner and Screaming Frog Certified Partner: we found no public certification under these names that an individual SEO can take.
- Hootsuite Social Media Certification: still a social media credential, not an SEO one.
- Generic “A/B testing” and “conversion rate optimisation” certifications: no single issuing body, so the names told readers nothing.
Moz is a special case. SEO.com’s 2026 roundup lists Moz’s SEO Essentials Certificate at US$595, but we could not load Moz’s own academy to confirm the current price, so it is not in our ten.
Do certifications get you hired?
On their own, rarely. A hiring manager reads a certificate as proof that you know the vocabulary and the tools. They hire on evidence that you can do the work: a site you improved, an audit you wrote, a clear answer to “what would you check first if traffic dropped?”
Use certificates to fill gaps, not to fill a CV. Add them to the Licenses and certifications section of your LinkedIn profile (our LinkedIn growth guide covers the rest of the profile), then put your effort into practical work. Our SEO expert skills roadmap sets out what to practise, and how to switch careers into SEO covers building a portfolio from scratch.
Frequently asked questions
What is the best free SEO certification?
For most beginners, HubSpot’s AEO Fundamentals or Semrush’s SEO Crash Course, paired with Google’s Analytics certification. Add the Ahrefs Certification once you use the tool.
Does Google offer an SEO certification?
No. Google publishes free SEO documentation through Search Central but does not certify SEO skills. Its Skillshop certifications cover Analytics and Google Ads.
Are paid SEO certifications worth it?
They are worth it when you need structure and deadlines. They do not carry more weight with employers than free ones by default. Choose a paid course for the teaching and feedback, not the certificate.
How often do SEO certifications expire?
Google, Semrush and Ahrefs certificates last one year. The other providers on this list do not state a period on the pages we checked.
If you want structured teaching with feedback on real work, SEOGidi’s 8-week SEO and growth marketing course starts its next session in January 2027.
