My Top 10 Best Free SEO Courses
1. Julian Goldie (free resources)
These are my own free resources, so I'm first by disclosure — a genuinely free Link Building Mastery book, free YouTube tutorials, and a free AI SEO prompt library. I keep them free because they're also how people find my work. Book a free call if you want a personal steer.
2. Google's SEO Starter Guide & Digital Garage
I always point beginners to Google's own free SEO Starter Guide and the free Digital Garage course first — it's straight from the source, trustworthy, and the certificate is free.
3. HubSpot Academy SEO Course
HubSpot Academy's free SEO course with a free certificate is one of the best structured free options out there, and I happily recommend it.
4. Semrush Academy
Semrush Academy's free courses and certifications are worth doing once you've got the basics — more tool-focused and a bit deeper.
5. Ahrefs' SEO Course for Beginners
Ahrefs' free beginner SEO course is genuinely excellent, especially on links and keyword research, which I obviously rate highly.
6. Moz Beginner's Guide to SEO
Moz's free 'Beginner's Guide to SEO' shaped how a lot of us learned — still a great, clear primer.
7. Yoast SEO Academy (free track)
Yoast's free beginner track is a sensible pick if you're on WordPress and want practical, no-nonsense guidance.
8. Backlinko's Free SEO Training
Brian Dean's free Backlinko training is clear and well-made — I don't agree with everything anyone says, but his free material is genuinely useful.
9. Coursera SEO Courses (audit free)
If you like structured, in-depth learning, the free-to-audit SEO courses on Coursera are worth a look — you only pay if you want the paper.
10. Free SEO Crash Courses on YouTube
And honestly, some of the best free SEO teaching now lives on YouTube — just be selective about who you trust.
Why I Give So Much Away Free
I put my own free resources first, which is obviously self-interested — but they're genuinely free, and I keep them that way because free, useful content is also how people discover my work. I'd hold every 'free' course to that standard: is it actually free and actually useful, or just bait for a paywall? The ones below pass.
How I'd Sequence Them
If I were starting again, I'd do Google's free guide first for the fundamentals, then HubSpot or Ahrefs' free course to go a level deeper, applying everything to a real site as I went. I wouldn't pay for anything until I'd exhausted the free options and hit a genuine ceiling.

The Free Resource I'd Start A Beginner On
If a friend asked me where to begin for free, I'd send them to Google's own SEO Starter Guide first — it's authoritative, free, and cuts through a lot of the noise. Then I'd have them do one structured free course (HubSpot's or Ahrefs') to go a level deeper, applying everything to a real site as they went. That combination alone takes most people further than they expect, for nothing.
The reason I'm relaxed about recommending other people's free courses, even competitors', is that genuine free education grows the whole space and makes people smarter — which is good for everyone, me included. I'd rather you learned properly from whoever teaches it best than stayed confused. So take this list in that spirit: a genuinely useful set of free options, mine included only because it's genuinely free and useful too. Judge them all by whether they help your site.
When It's Worth Paying (And When It Isn't)
Since this is about free courses, let me be honest about paid ones. For fundamentals, you almost never need to pay — the free options here cover it. Paid courses and communities earn their place when you want accountability, a specific advanced niche, or a network of people doing the same thing. That's real value for some people, but it's a step you take after the free stuff, not instead of it.
The trap is paying out of FOMO before you've exhausted what's free. I'd genuinely rather you worked through these free courses, applied them, and only spent money once you'd hit a real ceiling you couldn't get past for free. That order — free first, paid only when you've outgrown it — is how you get the most for the least, and it's the advice I'd give a friend regardless of whether they ever bought anything from me.
What It Comes Down To
Strip it back and learning SEO for free comes down to two things: pick a credible free course, and actually apply it. The specific course matters less than people think — Google's, HubSpot's, Ahrefs' are all genuinely good — but applying what you learn to a real site and measuring the results matters enormously. That's the difference between people who 'did some free courses' and stayed stuck, and people who quietly became good without spending a penny.
So take this list as a starting point, not a homework assignment to complete in full. Choose one, work through it, apply it, see what happens, and let your own results guide what you learn next. Do that consistently and you'll go further than you expect for nothing. And whenever you'd rather have experienced people handle the work while you focus on your business, that's a perfectly good choice too — book a call and we'll take it on.
