Free SEO and SEM certifications: what actually counts

By Miguel Maio · Published 20 October 2026

There's no free SEO certification an employer truly respects. Google has none. And that tells you more about SEO than any course.

Notice the asymmetry. For SEM there are official, free, recognised badges. For SEO there are courses, there are tool badges, but nothing with the same weight. This isn't chance. It's the nature of the two disciplines, and understanding why is worth more than the list of certificates.

Why there are SEM badges and not SEO ones

SEM runs on a platform with an owner. Google Ads is Google's, and Google has every interest in certifying whoever operates the tool where it makes money. So there are official exams, free, kept up to date: the more people who can use the platform, the better for the platform.

Google happily certifies whoever spends its budget. Whoever does SEO, and pays it nothing, is left out in the cold.

SEO has no owner. There's no company certifying whoever optimises for an algorithm it doesn't even fully control. Google, in fact, will never certify SEO, because that would mean blessing tactics on a system it wants to keep opaque. The result: the market filled SEM with official badges and left SEO to the specialists. Keep this in mind, because it's the key to everything that follows.

The SEM side: free and credible

Here life is simple. The certifications that count are free and give a verifiable certificate. The base is Google Ads, in Skillshop, which I covered in detail in the Google certifications: free, with a certificate, renewed every year. For SEM, start with Search.

Outside Google, two that count as an ATS keyword and as learning: HubSpot Academy (inbound, email, ads, with a free certificate) and Semrush Academy (strong on PPC and tools, also free). Neither makes you an expert on its own, but they add up on a CV and teach the right vocabulary.

The SEO side: the uncomfortable truth

Now the part nobody tells you plainly. The free SEO certifications that exist (HubSpot's SEO one, Semrush's) are useful for fundamentals and for putting "SEO" as a keyword in the ATS. But they're light, and they're brand-led: they teach the basics and, often, how to use the course provider's own tool. They're not proof that you can do SEO.

The SEO certifications with real depth are built by specialists, and they're paid. The reference is Blue Array Academy, the academy of a British SEO agency, with two worth a look: the Technical SEO Certification (14 modules, with Sitebulb involvement) and the SEO Manager Certification (23 modules, industry-recognised accreditation). They're taught by people who do SEO every day, not by academics.

Two honest caveats. First: they're paid, but Blue Array runs free, sponsored windows (the Technical one has been free with sponsorship before). Second: right now sign-ups are paused - the academy is refreshing its content and promises to relaunch soon (SEO, even in its own certifications, has indexing problems). Check availability before you count on them. It's worth watching for a free window: content of this level without paying is rare.

And beware a naming trap: there are Coursera courses with "Google" in the title that aren't Google's. Google SEO Fundamentals, for example, is from the University of California (UC Davis), not Google. In SEO, always read who teaches the course, not just the name.

The unbreakable limit: in SEO, the portfolio is the certification

Here's the heart of it. An SEO badge proves little, because there's no single correct method to certify. SEO changes with every update, and what proves you can do it isn't a certificate: it's having done it.

A site you took from zero to organic traffic, documented, with the before and after. A keyword study that organises demand instead of listing it. A technical audit that found what was blocking indexing. That's your SEO certification, and no serious employer trades it for a badge. How to build that proof is in your first marketing job.

Verdict, and what to do this week

For SEM, take Google Ads Search in Skillshop this week, free. Add HubSpot or Semrush if you want more keywords and more grounding.

For SEO, change the expectation. Don't chase a badge expecting it to open doors the way a Google Ads one does, because it won't. Take a free one (HubSpot or Semrush) for the fundamentals and the keyword, watch for a free Blue Array window if you want depth, and put all your energy into the portfolio. It's the portfolio that proves it. In SEM, the badge opens the door. In SEO, the door opens with work people can see.

This is one vertex of a larger triangle. The full map, of what a certification is worth and what it has to go hand in hand with, is in the digital marketing certifications that are worth it.
