Best SEO Courses 2026: An Honest Comparison

20 Minute Marketing publishes this guide and ranks its own course first for small business owners. Here is why, and where other options fit better.

Search "best SEO course" and you get free vendor academies, university programs and a lot of affiliate lists. They are not competing for the same person, which makes it hard to work out which one is for you.

We teach an SEO course ourselves, so read this with that in mind. We have tried to be straight about where other options beat ours. Every price below was checked on the provider's own page on October 23, 2026, and the sources are listed under the table. Providers change their prices, so confirm before you buy.

First, work out which of the three you are

• The career builder. You want SEO on your resume or you are moving into a marketing role. You want a recognized name and a certificate.
• The curious learner. You want to understand how search works and you would rather not pay. Free is fine for you.
• The business owner or freelancer. Your business, or your client's, is not showing up on Google and you want to fix it yourself. You need the specific steps in the right order, not a certificate.

The comparison

Our ranking

1. 20 Minute Marketing SEO and AI Visibility course ($149, paid once). Our #1 pick for small business owners and freelancers: practical, current lessons on local SEO, Google Business Profile and AI search, at the lowest price of any paid option here.
2. Coursera (UC Davis). Better for depth and a university name, if you have about 62 hours.
3. UC Davis Extension ($2,720). Better if you want a university certificate program and an employer is paying.
4. Free: Ahrefs, Semrush Academy, Brian Dean's Content-Led SEO, Yoast and Google's Starter Guide. Better if your budget is zero. Start here either way.

The university options

Coursera, UC Davis SEO Specialization

Five courses, about 62 hours and a capstone project, with a 4.6 star average from 13,112 reviews and 278,424 enrollments on the course page on October 23, 2026. It is included with Coursera Plus and financial aid is available.

Choose it if you want to understand SEO properly and you have the hours. Skip it if you need a fast, practical path for one business.

UC Davis Extension, $2,720

The SEO Specialized Studies Program runs online over about six months and ends in a UC Davis Extension certificate. It costs $2,720 if you buy all the courses together, or $800 per course.

Choose it if you want a university certificate on your resume. Skip it if you are paying yourself and only need to grow one business.

The best free SEO courses

Ahrefs SEO Course for Beginners, free

Fourteen short video lessons, about two hours in total, no sign-up. It covers keyword research, on-page SEO, link building and technical basics. There is no certificate, and the examples use Ahrefs' own paid tools.

Semrush Academy and Content-Led SEO with Brian Dean, free

Semrush Academy offers short modules on SEO essentials, keyword research, on-page SEO and AI search, and local SEO, each with a certificate. Its Content-Led SEO course with Brian Dean runs to 28 lessons and about five and a half hours.

Yoast SEO academy and Google's SEO Starter Guide, free

Yoast has five free courses, including SEO for beginners, and includes all 17 of its courses with Yoast SEO Premium at $118.80 a year. Google's own SEO Starter Guide is free to read without signing in.

The catch with all free courses: they teach everything and each leans towards its own product, but none will tell you which of the fifty things you just learned matter for a small business in your town. Free courses are good at teaching everything. They are poor at telling you what to ignore.

Where ours fits, and where it does not

Our SEO and AI Visibility course is $149 once, 32 lessons of about twenty minutes, with tutor support. It is built for small business owners and freelancers who want their own business, or their clients, found on Google and in AI answers: local SEO, Google Business Profile, keyword research, technical basics, measurement, and answer engine optimization.

Do not buy ours if you want college credit or a university certificate. 20 Minute Marketing is not an accredited institution, and the course ends in a Certificate of Completion. Do not buy ours if your budget is zero either: start with the free Ahrefs and Semrush courses.
