Completing the bundle earns you two certifications: an SEO Certification and a Digital Marketing Certification.

6. Technical SEO: Crawlability and Indexability By Yoast

• Best For: Optimizing crawlability and indexability with the Yoast SEO plugin.
• Cost: Included in all paid Yoast plans
• Duration: 2 hours of video across 5 lessons
• Certification: Yes

Yoast has renamed this course Technical SEO: Crawlability and indexability, and it is now included with every paid Yoast plan rather than sold as a standalone Academy subscription.

It teaches you how to:

• Configure your web server using best practices
• Identify and fix crawling and indexing errors
• Create XML sitemaps
• Control which parts of your website appear in search results

Why enroll in this course?

It is built for beginners and states that no prior experience is needed. The course opens by explaining how search engines work, which is genuinely useful if the technical side of the web is new to you: it is much easier to care about crawlability once you know what a crawler is doing.

It is short, at two hours of video across five lessons, and it is the most practical option on this list if you already run WordPress with Yoast SEO, because the instructions map directly onto the plugin's own settings. You get a certificate and a badge for your site at the end.

7. Technical SEO By LinkedIn Learning

• Best For: Beginners and intermediates who want a short, structured course.
• Cost: LinkedIn Learning subscription (one-month free trial)
• Duration: 1 hour 11 minutes
• Certification: Certificate of completion

Technical SEO by Dana DiTomaso is the shortest structured course on this list that still carries a certificate, and it is rated 4.6 out of 5 from 536 ratings.

The course covers:

• How crawlers work
• Strategies for increasing site speed and discoverability
• Schema, site architecture and URLs
• Image and video optimization
• Using analytics data and search results to drive ongoing SEO decisions

Why enroll in this course?

It covers something the other courses mostly skip: how to make concrete recommendations to IT teams and web developers so the fixes actually get implemented. On most sites that is the real bottleneck, not knowing what is wrong.

It is also part of a Professional Certificate from the Content Marketing Institute, and the certificate of completion shows on your LinkedIn profile under Licenses and Certifications, which is worth something if you are using this to get hired.

8. Technical SEO and AI Search Training By CXL

• Best For: Experienced SEOs adapting to AI-driven search.
• Cost: CXL subscription
• Duration: Two courses
• Certification: Yes

CXL has rebuilt this training and now sells it as Technical SEO and AI search training — two courses rather than one, available through a CXL subscription.

The two courses are:

• Answer Engine Optimization — optimizing pages for AI search, showing up in AI comparisons, and influencing what LLMs say about your brand.
• On-page, on-site and programmatic SEO — on-site strategy and content, internal linking, and SEO testing.

By the end you should be able to model how AI systems retrieve and synthesize content, build site architectures that support query fan-out and passage retrieval, structure pages for answer extraction and citation, design programmatic SEO that scales, and diagnose AI visibility loss.

Why enroll in this course?

CXL states plainly who this is for: experienced SEOs, technical marketers and content engineers. It is not a beginner course, and it assumes you already understand crawling, indexing and site architecture.

What makes it different from everything else on this list is the framing. Most technical SEO training still optimizes for crawlers and rankings; this one optimizes for retrieval and citation by LLMs and answer engines, and measures success in AI visibility rather than position. If that is the shift you are trying to get ahead of, this is the most direct route to it.

Are There Free Technical SEO Courses?

Yes. Four of the courses on this list cost nothing, and between them they cover most of what you need:

• Ahrefs — no registration at all, the whole thing is on YouTube. The fastest way to get oriented.
• Semrush — free, certificated, and the only free option that covers AI search.
• Alison — free and certificated, and the longest of the free courses at around eight hours.
• Coursera — free to audit, and only 40 minutes if you want the basics and nothing more.

So what does paying actually buy you?

Three things, and it is worth being honest that none of them is the material itself. The free courses teach the same crawling, indexing and Core Web Vitals fundamentals as the paid ones.

What you pay for is depth on complex sites (CXL and Brighton SEO go into log file analysis, programmatic SEO and international setups that the free courses skip), a credential someone recognises (Moz's certification carries more weight on a CV than a YouTube playlist), and structure and support — quizzes, feedback and a path through the material rather than a list of videos.

If you are learning technical SEO for your own site, start free and stay free until you hit something the free courses do not answer. If you are trying to get hired or take on clients, the certification is the part worth paying for.

How to Choose the Right Technical SEO Course

The courses on this list are not interchangeable. The fastest way to pick is to be honest about where you are starting from.

If you are a complete beginner

Start with Ahrefs or Coursera. Both assume no prior knowledge, both are free, and between them they take under two and a half hours. Their job is to make the vocabulary make sense — crawling, indexing, sitemaps, Core Web Vitals — so that everything else you read stops being opaque. Do not buy anything at this stage.

If you know the basics and want to go properly deep

This is where most people on this page actually are: you have run a site, you have seen Search Console errors, and you want to know what to do about them. Semrush and LinkedIn Learning both fit here, and Yoast is the most practical choice if your site runs on WordPress, because the instructions map onto settings you already have. If you want the technical SEO material alongside the rest of digital marketing, our own Complete SEO Course covers it as part of a wider bundle.

If you work on large or complex sites

CXL and Brighton SEO are the only two here that go into log file analysis, programmatic SEO, international setups and Python. Both explicitly assume existing SEO experience, and both will waste your money if you do not have it.

If you need the credential more than the knowledge

Moz is the certification with the most recognition in the industry, and that is most of what the $395 buys. Semrush and Alison both certificate you for free, which is a better trade unless a specific employer has asked for Moz by name.

One thing that applies at every level

Pick the course that matches the site you can actually practise on. Technical SEO does not stick as theory. If you have a WordPress blog, a course built around enterprise log file analysis will teach you nothing you can use this month.
