    • Walsh flags what to focus on instead of explaining everything, which students appreciate
    • Free, with 25 caption tracks and about 360,000 enrolled
    • Last updated February 2021; low-star reviews say some information and a recommended site are outdated

AI SEO Course 2026: From Zero to Page-One Results (AEO, GEO)

4.6
(20,471 reviews)
byArun Nagarathanam

A 15-hour, quiz-heavy SEO course refreshed in mid 2026 that runs from keyword research through Core Web Vitals to link building, with a short AEO and GEO add-on.

Best for: Marketers and developers with some SEO exposure who want a full refresh, including site speed and schema, in one place.

icon
Pros
icon
Cons
    • Clear structure with 56 quizzes between lessons that reviewers say help the material stick.
    • Two technical SEO sections, over three hours, cover site speed, Core Web Vitals and JavaScript rendering.
    • Returning and experienced SEOs say it caught them up on recent changes and the AI side of search.
    • Updated July 2026, with an 18-lecture section on pricing, clients and building an SEO career.
    • Pace is slow for anyone with experience; a three-star reviewer says simple topics get over-explained.
    • The AEO and GEO section is only five lectures and about 13 minutes despite the title's billing.
    • One reviewer reports the Gemini prompts that used to be in the resources can no longer be found.

byJoshua George

A UK agency owner's step-by-step ranking process, from keyword research to link building and WordPress speed, with his working spreadsheets thrown in.

icon
Pros
icon
Cons
    • Agency spreadsheets included as downloads, so the process is reusable on your own site
    • A worked example for nearly every topic; reviewers call the steps actionable and easy to follow
    • Link building gets 22 lectures and nearly 3 hours, the longest section in the course
    • Refreshed in September 2026, with 24 caption tracks available
    • Some sections are text transcripts of the video, which pads the 14-hour runtime
    • Several examples predate 2023 and AI-era search gets little attention
    • Leans on a premium SEO tool; free alternatives are shown but the main demos use the trial

    • 22 assignments plus templates and a starter pack give something to practice on, not just watch
    • Around 61 percent of 54,000 ratings are five stars, with very few one or two star reviews
    • Two one-star reviews say lessons lean on pasting a ChatGPT prompt instead of teaching marketing
    • Some sections feel repetitive and padded, and one 2026 review still calls parts outdated
    • Following the website section means paying for Bluehost hosting

    • Reviewers say some lectures date from 2018 and the Google Ads and Facebook walkthroughs no longer match the platforms
    • Around 12 hours of WordPress arrives early; one reviewer called building the site an unplanned expense
    • Long and, per several reviewers, slow and monotonous; even a fan calls it a little boring because it is too detailed
