AI SEO Rainmakers vs AI SEO Mastery Pro: $319 vs $217, Which Skool Group Fits You?

By Owen HalePublished 6 Sep 2026Paid member since 2 Sep 2026

Affiliate disclosure: we paid $269 for our own seat and earn a commission if you join through our links. That does not change the price you pay.

Two paid AI SEO groups on Skool, run by two operators who could not be more different. Charles Floate charges $319 a month for AI SEO Rainmakers and teaches black and gray hat plays on camera. Caleb Ulku charges $217 a month for AI SEO Mastery Pro and teaches local SEO agency owners how to rank client sites with AI. We pay for Rainmakers. We have not paid for Mastery Pro, so every Mastery Pro fact here comes from its public Skool about page and from ippei.com, both checked on 6 September 2026.

Side by side

Evidence basis. AI SEO Rainmakers column: we have been paying members since 2 Sep 2026, so it comes from inside the classroom plus the Skool about page, read on 11 Oct 2026. AI SEO Mastery Pro column: its public Skool about page, read on 17 Oct 2026, plus ippei.com, a third-party listing, for the launch year. We are not members, so none of it is observed from inside.

Who runs each group

Charles Floate is a British SEO based in Koh Samui, Thailand. He started SEO at 12, got kicked out of school at 15 over hacking, and was Head of SEO at SUSO Digital in London by 17. Google penalised him personally in 2013 and again in 2016 for teaching black hat in public. He has since trained 20,000+ SEOs through 25+ courses, ran a consulting desk at $800k a year by age 27, and as CMO took PressWhizz from $60k to $750k a month before stepping back in July 2026. He launched AI SEO Rainmakers on 10 August 2026. The 100 founding seats sold in 7 hours. More on the Charles Floate page.

Caleb Ulku runs a local SEO agency out of Gulfport, Mississippi. His Skool bio reads: 7-figure local SEO agency owner, former chemical engineer. ippei.com (review dated 22 May 2026) adds that he founded his agency in 2014, spent close to ten years at ExxonMobil as a refinery coordination supervisor, and holds a chemical engineering degree from The Cooper Union plus a master's from Chicago Booth. His signature method is Core 30: build 30 interlinked pages that mirror a client's Google Business Profile categories and services. His Skool account dates to April 2023, and ippei says the community was founded that year.

One is a lifelong SEO who treats Google as an opponent. The other is an engineer who turned a marketing agency into a system. That difference runs through everything below.

Price, and how each one changes

Mastery Pro is simple. The Skool page shows $217 a month, or $1,497 a year, as of 17 Oct 2026. ippei.com quoted $197 a month or $997 a year in May 2026, so the price has moved up $20 since then. We could not find a current annual option on the Skool page.

Rainmakers uses a ladder. Founding members paid $179. The rate then climbed $10 for every 25 seats, from $199 up to $289, and the Skool page now says the block after $319 costs $329 or more. The current block of seats pays $319, which is the live rate as of 11 Oct 2026 with 404 members counted on the about page. The Skool page says the next block moves to $329 or more. Your rate locks for as long as you stay subscribed, and Charles says it never comes back down. Full price breakdown on our pricing page.

Over 12 months at today's prices the gap is $1,224. If the next Rainmakers block opens at $329, as the Skool page says, the gap becomes $1,344 a year. Anyone reading a review that quotes $259 is reading something from late August.

Members, reviews and refunds

Mastery Pro has 715 members and 11 admins as of 17 Oct 2026. Its rating is 5.0 from 12 reviews, up from 4.9 from 10 on 6 September 2026. For a community that has run since 2023 that is a small review base, which may say more about Caleb not asking for reviews than about the product.

Rainmakers had 404 members and 4 admins on 11 October 2026, two months after launch, with a 5.0 rating from 48 reviews. The 31 reviews we read on 7 September all came from members 11 to 21 days in. Four times the reviews in a fraction of the time, but mostly from people still in their first weeks. Brand new is a real caveat.

Refunds separate the two hard. Rainmakers offers a 7-day 100% money back, no questions, and you keep the downloads. The condition on the Skool page is that you DM Charles before you reach level 3, which is a Skool engagement level earned by posting and likes. Mastery Pro's Skool page ends with "All sales final". ippei.com's May 2026 review mentions a 7-day guarantee, but the live page does not, so plan for no refund.

What you get inside

AI SEO Rainmakers

A weekly live Q&A on Wednesdays at 6pm Thailand time (UTC+7). The recordings we watched ran 3h57m across 3 calls, because Charles stays until every question is answered. A classroom of 14 courses and 128 modules as of 11 October 2026 (10 when we joined), gated by Skool level: on day one most of it was locked, and by day 3 seven of the ten were open. Four downloadable repos (parasite-builder, build-agent, mini-brain, and a monthly Operator roadmap through December 2026), a Claude Skills Library, CharlesGPT 3.1 as a custom GPT, and on 5 September a drop of 100+ AI SEO skill files covering local agency, ecommerce and site recovery work. The feed passed 540 posts in three weeks. Total classroom video we measured: 6h37m across 27 lessons, and about 60% of that is the call recordings. The curriculum page lists every course with its lesson count.

AI SEO Mastery Pro

On 17 Oct 2026 the Skool page lists these for $217 a month: Tuesday calls with Caleb, Thursday build sessions with Mark on the Core30agent tool, a full Core30agent account with enough usage to run five clients at his agency's pace, a course library covering GBP, AI content, off-site and ChatGPT optimization with his agency's prompts in each lesson, and a 1-1 onboarding call. ippei.com names five course tracks: Modern SEO, AI SEO Mastery, AI-Powered Success on Upwork, Build Your Virtual Team, and SEO Bootcamp. We cannot confirm video hours or lesson counts because we are not members. If you want that detail, ask in the Skool feed before you pay, since there is no refund.

Teaching style

Charles teaches like someone who has been penalised twice and kept going. Black and gray hat plays sit in the open: parasite SEO, a Dark Library course that includes a "Bypass Fable Safeguards" lesson, live site teardowns. He answers questions on the call with specifics, and he ships code. The repos and the vibe-coding course expect you to open a terminal. The Foundations course runs 9 lessons and 38 minutes of video, with a tracking sheet and a 7-day plan attached. It is dense and it assumes you already do SEO.

Caleb's page pitches the calls as the product. His own words: weekly calls where he breaks down what is working in members' businesses and solves their problems live. The framing throughout is agency delivery for local clients, with AI used to cut research and content time. ippei's main worry, in its May 2026 review, is that heavy AI content use can drag quality down. That is a fair flag for any prompt-library approach and it applies to parts of Rainmakers too.

Who each group suits

There is a third answer. Neither, if you are new to SEO. Our review scored Rainmakers 2.8 out of 5 for beginner friendliness. Mastery Pro's Core 30 is easier to follow, but $217 with no refund is a hard first purchase. See our best AI SEO Skool communities list for the free and cheaper groups, and the Rainmakers alternatives page for what else we would pay for.

Our pick, with the caveats

We chose Rainmakers, and we still would. The weekly call with direct answers, the repos, and the pace of new material (100+ skill files dropped on 5 September) are the reasons. Our sister review scored it 4.8 out of 5.

Three caveats. First, we have not paid for Mastery Pro, so this is one side seen from inside and one side seen from the door. Second, Rainmakers is the most expensive group in the category and the price only goes up. Third, the black and gray hat lean is a feature for some and a deal-breaker for compliance-heavy teams. If you work in a regulated vertical or answer to a legal department, Caleb's group is the safer buy. We also compare Rainmakers to a much cheaper AI-citation group in Rainmakers vs The New Search.

Whichever group you pick, a single AI SEO Rainmaker seat or a Mastery Pro seat is a month-to-month test. Give it four weeks, attend every call, and cancel if you are not applying what you learn.
