SEO Certification: The 6 Best Courses to Get Certified in 2026

The Digital Marketing Institute (DMI) Search Marketing course leads to the Certified Digital Marketing Specialist in Search Marketing credential. It packs approximately 30 hours of online content into ten modules, from SEO setup and on-page work through paid search, analytics and search strategy, and you have up to 24 weeks to finish. DMI positions the credential as equivalent to a level 5 qualification in the UK grading system, and the course earns CPD credits (continuing professional development hours that many employers and associations track).

What sets it apart is the exam. You sit one two-hour exam and need at least 60% to pass, and the exam fee is part of the price. A resit after a failed attempt costs about €75. The list price is $2,060; a pay-in-full offer cuts it to $1,339, and a three-installment plan ran $447 a month. Treat the lower figure as a promotion that can change. The real limit is scope: three of its ten modules cover paid search and Google Ads, so a pure SEO practitioner pays for content they may not use.

The University of California, Davis built this five-course specialization on Coursera. It starts with SEO fundamentals and ends with an 11-hour capstone, the Google SEO Capstone Project, where you apply what you learned to a real case. Coursera estimates two months at ten hours a week. Finish all five courses and you earn a career certificate from UC Davis. Courses in the series average 4.6 from 13,113 reviews.

The price is the subscription: Coursera Plus costs $59 a month after a seven-day free trial, so two focused months come to about $118. The annual plan lists at $399 and is often discounted. Two caveats. There is no timed exam: assignments are peer-graded, so the certificate proves completion more than mastery. And read the reviews by date: the harshest are old (in 2019, one learner called the first courses "a waste of time"), so check the recent ones and the syllabus of the first two courses before you subscribe, then spend most of your time on the capstone.

Semrush, the maker of the SEO platform of the same name, runs a free academy with a full SEO track. A current example is On-Page SEO and AI Search Essentials with Semrush: 23 short lessons, about an hour, taught by Alex Lindley, covering on-page work and visibility in AI-driven search. Complete a course, including its quizzes and exam, and you receive a Semrush certificate. You get three attempts to pass each exam.

Know what you're holding. Each certification is valid for one year from the date you complete it, so it needs renewing to stay on your profile. It proves you finished a vendor course and passed its quiz, and it shows you know the Semrush tool. That's useful for an entry-level resume or as a free check of your level before you spend real money. It won't carry the weight of a timed, paid exam with a hiring manager in the field.

Moz, the company behind the Moz Pro SEO software, sells SEO Essentials as an intensive six-part course and exam series. You take an exam at the end of each of the five content sections, then a final exam, and Moz puts the total time commitment at about eight hours. You keep access to the course materials for one year from purchase.

At $595, the question is value. You get a tighter format than a free vendor course and exams at every step, but six hours of instructor-led content (about eight hours with the exams) is short for the price. It suits someone who already has a basic grounding and wants a recognizable brand on a short certificate, or a manager who wants to check a team's basics. If you use Moz Pro at work, our page on switching from Moz Pro compares it with the tools your team may move to.

SEOtraining.com is the online training arm of Bruce Clay, an SEO firm. It works as a membership: continual SEO tips and lessons, plus access to an SEO community. You choose how to pay: $99 a month, or $990 upfront for the year. In-person classes run as well, over three days. On top of the training, Bruce Clay runs its own certification: 80 multiple-choice questions in one hour, 80% to pass, with up to three retries. Certified members get 20% off the online membership plans.

The membership model is the draw and the catch. It suits someone who wants to keep learning as search changes, rather than finish a course and move on. But you pay every month or every year, and the certification page doesn't list an exam fee, so ask for it before you commit. For a team, the annual plan is the simplest to budget. For a one-off credential, DMI or Moz will get you there with a single payment.

HubSpot Academy's AEO Fundamentals is a free certification course. AEO stands for answer engine optimization: getting your content cited by AI assistants as well as ranked in classic results. The course runs seven lessons in 2 hours 20 minutes and teaches you to build a content strategy that earns visibility in both traditional search results and AI-powered answer engines.

It's a good fit for the moment, but it's a vendor certificate, and it sits at the shallow end: two hours of content and a quiz. HubSpot's other certifications are covered on our HubSpot certification page, and our HubSpot review covers the software itself. Use AEO Fundamentals to frame how AI is changing search, then go deeper with one of the paid options above.
