8 Best SEO Certifications of 2026
This list is for marketers who want to add a search engine optimization credential: content writers, generalists who now own organic traffic, and career switchers moving into SEO roles. We compared eight credentials from Coursera and UC Davis, Semrush, Yoast, Ahrefs, Moz, the Digital Marketing Institute and Simplilearn using what each provider publishes about course length, exam format, validity and price. Scores weigh features (depth, assessment and recognition) at 40 percent, and ease of access and value at 30 percent each. We compared documented features and published prices. Two providers did not show a USD price on the pages we could fetch, so those rows are marked pending.

Mojolin is self-funded How we score
The UC Davis SEO Specialization is our top pick: it is the most complete structured program here and the certificate carries a university name. Semrush Academy, Yoast SEO Academy and the Ahrefs Certification are free or close to free and worth adding on top, especially if your team already uses one of those tools. Moz's SEO Essentials ($595) and Technical SEO ($395) certifications suit marketers who want exam-based credentials from an SEO company, while DMI and Simplilearn cover people who prefer a certification body or live classes.

UC Davis Search Engine Optimization (SEO) Specialization
A five-course SEO program from the University of California, Davis on Coursera that ends in a hands-on capstone project.
coursera.org8.5
out of 10
Best for: marketers who want a university-branded SEO credential
The UC Davis SEO Specialization is the most complete structured SEO program on this list that a working marketer can finish in a couple of months. Coursera lists five courses of 14, 10, 13, 14 and 11 hours and estimates about two months at 10 hours a week. The first four courses cover how search works, competitive analysis, keyword research and content marketing for rankings; the last is the Google SEO Capstone Project, where you apply the material to a full SEO consulting task and create an SEO pitch. The certificate comes from the University of California, Davis, which carries more weight on a resume than a software vendor badge. Coursera charges $49 to $79 a month for individual programs in the U.S., so finishing quickly keeps the cost low. The drawbacks: Coursera says the program cannot be taken free and does not carry university credit, and one learner review on the page notes that some tools used in the courses are no longer free.

Rank 2 · Runner-up
Semrush Academy SEO certifications
Free short SEO courses from Semrush, each ending in a certification exam.
semrush.com8.4
out of 10
Best for: marketers who want a free SEO certificate this week
Semrush Academy is the fastest way to put an SEO certificate on your LinkedIn profile. Each course is a set of video lessons with scripts, short quiz questions and a final exam; pass it and Semrush sends a personalized certificate you can download and share. The SEO track includes SEO Essentials with Semrush, which covers keyword research, content optimization, backlink identification and an introduction to AI visibility, and courses such as On-Page SEO and AI Search Essentials and Keyword Research Essentials that run about an hour each. Semrush states that the certifications are completely free. Two limits matter. The courses teach Semrush's own tools, so they work best for marketers who use or plan to use Semrush. And the Academy is moving to a new platform on December 16: Semrush asks learners to finish courses and download certificates by December 15 because unfinished progress will reset. Treat these as quick proof of tool skills, not as a substitute for a longer program.
Standout feature

Use cases

Learn the Semrush workflow for keyword research and on-page SEO
Outcome: A free certificate tied to the tool the team uses

- An hour-long course is a light signal to employers

Ahrefs Certification
A free 67-question exam that certifies you can use Ahrefs tools, workflows and reports.
ahrefs.com8.2
out of 10
Best for: SEO specialists and agency staff who use Ahrefs
The Ahrefs Certification is a scored exam rather than a course certificate, which makes it a stronger signal than a completion badge. Ahrefs lists 67 questions, a one-hour limit and a 75 percent pass rate. Any Ahrefs account works, paid or non-paid, and you get three chances to pass before a 15-day wait. The certification is valid for one year from the date you complete it, so you retake it to keep it current. Ahrefs Academy offers free preparation, including a course on using Ahrefs' SEO tools and reports (63 lessons, 3 hours 18 minutes) and a free SEO Course for Beginners covering keyword research, on-page SEO and link building. Ahrefs also lists a newer AEO certification on answer engine optimization. The limit is focus: the exam proves you can use Ahrefs, so it matters most to agencies and teams that already pay for the tool.
Standout feature
A free, timed 67-question exam with a 75 percent pass mark.
Use cases
Agency SEOs
Show clients they can work in Ahrefs
Outcome: A free, exam-based credential valid for a year
Freelancers
Add a tool credential to a profile
Outcome: Proof of Ahrefs workflow knowledge
Key features
- 67 questions, 1 hour, 75% pass rate
- Any Ahrefs account can take it, paid or non-paid
- 3 chances to pass, then a 15-day wait
- Valid for 1 year from completion
- Free Ahrefs Academy prep courses, including an SEO Course for Beginners
Pros
- Free exam
- Timed, scored format is harder to pass than a completion certificate
- Free prep courses on Ahrefs Academy
Cons
- Tests Ahrefs product knowledge more than general SEO
- Expires after 1 year
- Little value if your employer uses a different SEO tool
Rank 4
Yoast SEO Academy
SEO and WordPress courses from the makers of the Yoast SEO plugin, with a certificate for every course.
yoast.com8.2
out of 10
Best for: WordPress site owners and content writers
Yoast SEO Academy suits marketers who work on WordPress sites. Five courses are free and each ends with a certificate: SEO for beginners, Structured data for beginners, WordPress block editor training, WordPress for beginners and Yoast SEO for WordPress plugin training. Yoast says no payment details are needed for those. The rest of the catalog, including Keyword research, SEO copywriting, Site structure, Local SEO, International SEO, Ecommerce SEO, AI for SEO and two technical SEO courses on crawlability and hosting, comes with the Premium plan at $118.80 a year, which also includes the Yoast SEO Premium, Local SEO, News SEO and Video SEO plugins. Yoast awards a certificate and badge for every course you complete. The trade-off is scope: examples and tooling center on WordPress and Shopify, and the credential comes from a plugin vendor, so it reads as practical training rather than a formal designation.
Standout feature
Five free courses with certificates, and every course for $118.80 a year.
Use cases
WordPress bloggers
Learn on-page SEO in the plugin they already use
Outcome: Free certificates and better use of Yoast's analysis
Small agencies
Train writers on SEO copywriting and site structure
Outcome: Course access bundled with the Premium plugin
Key features
- Five free courses, each with a certificate
- Premium plan includes every Academy course plus the Premium, Local SEO, News SEO and Video SEO plugins
- Paid courses include Keyword research, SEO copywriting, Site structure, Local SEO, International SEO and Ecommerce SEO training
- Technical SEO courses on crawlability, indexability, hosting and server configuration
- A certificate and badge for every course completed, including free ones
Pros
- Free courses need no payment details
- Premium bundles the courses with the Yoast SEO Premium plugin
- Courses map to the plugin many WordPress sites already run
Cons
- Full course access is tied to buying Yoast SEO Premium
- Content focuses on WordPress and Shopify sites
- Certificates come from a plugin vendor, not an independent body
Rank 5
Moz SEO Essentials Certification
A paid six-part course and exam series from Moz Academy covering core SEO.
moz.com8.0
out of 10
Best for: marketers who want a paid, exam-based SEO credential
Moz has taught SEO for years, and its SEO Essentials Certification is the paid flagship of Moz Academy. Moz describes it as an intensive six-part course and exam series priced at $595. The catalog tags it with keywords, research, links, page optimization and agency topics, and lists levels from beginner to advanced, so it suits marketers who already know the basics and want to go deeper. If you need only one area, Moz sells narrower certifications at $395 each for keyword research, local SEO, technical SEO and SEO competitive analysis. Moz Academy also has free courses, such as 30 Days of SEO and How To Use Moz Pro, which are a good way to check the teaching style before paying. The cost is the main drawback: $595 buys a lot of Coursera months, and parts of the material use Moz Pro.
Standout feature
A six-part course and exam series for a one-time $595.
Use cases
Marketing generalists
Formalize SEO skills with exams
Outcome: A Moz certification across core SEO topics
Agency teams
Train new hires on a shared SEO baseline
Outcome: A one-time cost per person
Key features
- Six courses plus exams
- Topics tagged keywords, research, links, page optimization and agency work
- Levels run from beginner to advanced
- Moz also sells Keyword Research, Local SEO, Technical SEO and Competitive Analysis certifications at $395 each
- Free Moz Academy courses such as 30 Days of SEO
Pros
- Exam series rather than a single quiz
- Covers SEO broadly instead of one product
- Free Moz courses let you sample the teaching first
Cons
- $595 is the highest verified price here
- Some modules teach Moz Pro
- Shorter than a university program

DMI SEO Foundations: Core Practices and AI Search
A 3.5-hour Digital Marketing Institute short course with a 40-question online exam and an Associate certificate.
digitalmarketinginstitute.com7.7
out of 10
Best for: marketing generalists updating SEO skills for AI search
The Digital Marketing Institute is an independent certification body, and its SEO Foundations: Core Practices and AI Search short course is a compact way to get a DMI credential in SEO. DMI lists 3.5 hours of self-paced content in three modules, covering how search engines and AI-powered search find content, keyword research, and on-page, local and international SEO. Assessment is a one-hour online exam with 40 questions in multiple-choice, matching and drag-and-drop formats, and passing earns an Associate level certificate. DMI says the course suits people new to SEO and marketers updating their skills, and it includes DMI Professional Membership. A follow-on course, Advanced SEO and AI Performance, adds about three hours on ecommerce and technical SEO. We could not see a USD price on the page from our location, so check the price at checkout.
Standout feature
A 40-question exam after 3.5 hours of SEO and AI search content.

Rank 7
Moz Technical SEO Certification
A five-part Moz Academy course and exam series focused on technical SEO.
moz.com7.6
out of 10
Best for: marketers who handle site audits and technical fixes
Most SEO certificates stay with keywords and content, so a technical SEO credential stands out on a marketer's resume. Moz's Technical SEO Certification is a five-part course and exam series priced at $395, and Moz says it teaches technical SEO comprehensively. The catalog lists it across levels up to advanced. It is the right add-on for marketers who run site audits, work with developers on crawl and indexing issues, or manage large sites. Moz sells the same format for keyword research, local SEO and competitive analysis at $395 each, and its $595 SEO Essentials series covers the broad basics. The limits are scope and price: one topic for $395, and some material uses Moz Pro. If you only need the concepts, Yoast's paid technical SEO courses come bundled with its Premium plan.
Standout feature
A dedicated technical SEO course and exam series for $395.
Use cases
Marketing ops staff
Work with developers on crawl and index issues

Rank 8
Simplilearn SEO Certification Training Course
An instructor-led SEO course with live sessions, a project and content aligned with OMCP standards.
simplilearn.com7.3
out of 10
Best for: learners who want live instruction
Simplilearn's SEO Certification Training Course is the only option here built around live classes. Simplilearn says the content is aligned with OMCP standards and taught in live interactive sessions by SEO practitioners, with recordings if you miss a class. To earn the certificate you attend 80 percent of the live sessions and complete one project, and the course includes two practice tests. The curriculum runs from fundamentals through technical topics such as sitemaps and site speed, and students get one year of free access to the SE Ranking platform. There are no prerequisites. This format suits people who learn better with an instructor and a schedule. The downsides are the time commitment of live sessions, a credential that comes from a training company rather than a certification body, and a price we could not confirm in USD from our location.
Standout feature
The only live, instructor-led SEO course on this list.
Use cases
Career changers
Learn SEO with a live instructor
Outcome: A project-based certificate
Teams
Train together on a schedule
