Phil Hudson runs the SEO agency Rook Digital, and his approach to membership site SEO rests on one unfashionable idea: the fundamentals never changed. The AI search everyone is racing to optimize for rewards the same things good SEO always has – structured data, genuine expertise, proof – and those are the exact things AI can't generate on its own.
For a membership site, that idea collides with a built-in problem. Your most valuable content – the courses, the community, the systems people pay for – sits behind a paywall, which is where it belongs and also where search engines and AI can't see it. What can't be crawled can't be recommended. This is a breakdown of how a membership site still gets found: the free layer that does the discovery, the schema that makes you legible to AI, and the kind of proof no competitor can fake.
The paywall problem is real, and gating is still the right call
A membership site runs on a contradiction. The content that justifies the subscription – training, tutorials, sequences, the proprietary stuff – has to be protected. Put it in public and two things happen: anyone who can prompt well extracts your system for free, and AI indexes it and hands it out to everyone else. Phil's view is that the wall is a feature.
“If you have it behind a wall that's not indexable, AI can't steal it.”
The cost of that protection is invisibility. The same paywall that stops AI from taking your work also stops it from finding you. So the job isn't to expose the paid content. It's to build a public layer that does the finding.
Where membership site SEO actually happens: the free layer
Getting found organically comes down to the oldest question in marketing: give away free content that answers something people actually ask. Phil splits the audience by temperature. Cold traffic doesn't know they have a problem, so selling to them fails; that content's job is to make them problem-aware. Warm traffic knows the problem and is building belief that a solution exists. The hottest segment is comparing providers and looking for proof – testimonials, case studies, objection handling.
Public content has to serve all of those stages, and the highest-leverage move is fielding the questions people are already typing. “If you can explain someone's problem in words more clearly than they can, you are the expert.” That's not an SEO trick. It's old sales psychology that happens to be exactly what AI rewards when it decides who to cite.
Phil says conversion rates from AI traffic run higher than from traditional SEO traffic. The trust people place in an AI recommendation carries over to whoever it names. The old middle-of-funnel metrics – time on site, pages per visit – are dying as no-click search absorbs them. What matters now is whether you're one of the two names that make it through the filter.
Schema is the foundation, and it predates the hype
The “AI optimization” acronyms everyone is throwing around – AIO, GEO, AEO – all point to the same thing: structured data, also called schema markup. Phil has used it since 2011, and his take is blunt. It was always the way to feed search engines your best information in a form they can't misunderstand, and AI crawls the same way. Most sites still skip it.
“If you are not paying attention to the structured data on the public facing version of your website, you are behind the curve.”
He's specific about depth. You can go a mile wide or a mile deep with schema, and the sites that win go deep on every post type – FAQ schema, video schema, quote schema – so an article isn't just text but a labeled object the machine reads with confidence. Picture an optimized article on how to grow a membership site: an embedded YouTube video (YouTube being Google-owned and the second-largest search engine), three to five marked-up FAQs at the bottom, citations to named experts. Every part of that stack is something AI can parse and trust.

The one thing AI can't fake: experience
Google's guidelines have long rewarded expertise, authority, and trust. The recent addition is a second E: experience. Phil's point is that experience is the one signal AI can't manufacture, which is why its absence is now a tell. Sites dumping AI-written content in volume produce expertise-shaped text with no lived experience behind it, and that gap is a red flag Google actively looks for.
For a membership operator, that's good news. Your direct experience – this member was stuck on X, we changed Y, they got Z – is the exact thing a language model can't invent. Phil calls AI an “idiot savant”: it knows everything and understands nothing, plausible on the surface and wrong underneath if you have the domain expertise to check. His example from the screenwriting world: an AI wrote a spec script, a second AI graded it “high marketability,” and a thirty-year showrunner could name a thousand things wrong with it. The lesson transfers. You still need a human in the loop who knows enough to catch the confident nonsense.
Keyword density is not keyword stuffing
Keyword stuffing and keyword density are not the same thing, and conflating them is how people get penalized. Stuffing is shoving the same term across your site with no plan; it's been dead for years. Density is deliberate: using your main keyword phrase a set number of times in the right places – the title, the description, the H1, an H2, and roughly two percent of the body. “Not times ten keywords, but two percent.” Do that, get the rest of the fundamentals right, and you rank better. Phil says he's never seen it fail inside the safe range.
Readability sits next to it. He aims for around an eighth-grade reading level, a Flesch score in the 60 to 80 band, because content that's too hard or too easy hurts time on site, and every engine from Google to Gemini watches that.
Case studies carry the proof
“One of our membership sites was struggling to grow with X, Y, Z, and we recommended A, B, C, and now they got E, F, G. That cannot be made up.” That's Phil on case studies, which he called the linchpin of proving expertise. If experience is the signal AI can't fake, a case study is how you show it.
They don't need to be monolithic. A small, annoying problem you solved for one member is a case study. Before and after: here's where they were, here's the one thing that changed, here's the result. A weight-loss before-and-after photo is a visual case study; a member who went from avoiding a task to handling it is the same structure in words. The point is proof that the product does what it sells, in a form no competitor can copy and no AI can hallucinate.
The same logic protects retention, not just discovery
The experience principle doesn't stop at getting found. Phil and Vic arrived to the same observation about why members stay: most people who pay for a membership consume very little of the static content. What keeps them subscribed is the community and the access to the person behind it. As AI commoditizes generic how-to content, that human element gets more valuable, not less. Polished, perfect videos convert worse than the messy, obviously-human ones – the imperfection is the signal. The same thing that makes your content rank is the thing that makes your membership worth keeping.
What membership and eLearning operators can take from this
Phil runs a digital marketing agency, not a membership site. But the approach translates cleanly for anyone doing membership site SEO on WordPress.
Build a public layer that answers questions, and let the paywall stay a paywall. The protected content is your value and your defense against AI scraping it. The free content is your discovery engine. Two different jobs; trying to make one do the other is where sites get stuck.
Schema is the highest-leverage thing most sites still haven't done. Phil's step for this week: run your homepage, product, and category pages through a schema validator, then check your top three competitors. If they have markup you don't, generate your own with an AI tool and match it. If none of you have it, you can get ahead in a week and a half. While you're in there, the free basics catch a surprising number of sites off guard – Google Analytics, Search Console, and Microsoft Clarity are free, and plenty of operators haven't installed them.
Your experience is the moat. Case studies, direct results, the specific change you made for a specific member – that's what proves expertise to Google and to buyers, and it's the one input AI can't generate. If your content could have been written by a model that never met your members, it reads that way to the systems now deciding who gets cited.
The through-line across everything Phil said: stop chasing the algorithm and do the fundamentals, because the fundamentals are now the part AI can't counterfeit.
