Restricted Category AI Visibility Index 2026

Updated September 17, 2026.

Answer engines like ChatGPT, Claude, Gemini, and Perplexity do not block adult, wellness, and creator-economy brands from AI search results. They block generic discovery of those categories while still surfacing the brands by name. Everything-PR's Restricted Category AI Visibility Index, Volume 1, documents this pattern, called the Naming Threshold, and four related findings across fifteen brands and four engines.

Why This Study Matters

Search-engine results ranked by backlinks and keywords have been displaced by retrieval systems that synthesize a single answer from a curated subset of the web. ChatGPT, Claude, Gemini, Perplexity, and Google AI Overviews decide which brands enter that answer. Reddit, Wikipedia, mainstream press, and wellness publishers decide what those engines see in the first place. This chain, from source material to a generated answer, is what this study calls the retrieval layer.

This pilot uses the adult industry as its principal case: the most heavily regulated restricted category, the least institutionally covered, and the most analytically informative. It is not a study about pornography. It is a study about how AI systems decide which legal but restricted industries are allowed to surface in discovery, a pattern that extends to cannabis, gambling, crypto, supplements, telehealth, and alcohol.

The Five Findings

The Naming Threshold. Answer engines surface restricted-category brands when a user names them directly, then route around the entire category when the same need is queried generically. "Best subscription platforms 2026" returns Patreon and Substack. "OnlyFans alternatives" returns Fansly, Fanvue, ManyVids, JustForFans, FanCentro, and LoyalFans. Same engine, same underlying need, two different brand universes.

The Wellness Passport. Categories institutionally framed as wellness, health, or personal care receive clean retrieval; tube sites, creator platforms, and cam platforms do not. Lovense surfaces in mainstream "best vibrators 2026" coverage. Pornhub does not. The wellness frame functions as a second, parallel channel that the retrieval layer trusts.

The institutional authority layer is the real gatekeeper. Whether a brand surfaces in unprompted discovery depends on Wikipedia, mainstream press, wellness publishers, and creator-economy guides. Trade press alone does not unlock retrieval, and neither do affiliate publishers. Only tier-one institutional sources do.

Factual accuracy is strong once an engine engages. Pornhub's ownership chain, Aylo (formerly MindGeek), owned by Ethical Capital Partners since March 2023, is retrieved consistently and accurately. The problem is not how AI describes the industry. It is whether AI surfaces the industry at all.

Crisis cycles become permanent training-data events. The December 2020 Visa and Mastercard withdrawal from Pornhub, and the state-by-state age-verification rollout that has since blocked Aylo properties in roughly twenty-five U.S. states, each generated institutional press coverage that now anchors that brand's retrieval-layer description for years. The retrieval layer is structurally biased toward documenting friction over function.

The Index Framework

Volume 1 presents index probes that illustrate each finding above; the fifteen-brand pilot set below is the designed foundation for the fuller test matrix described in "What Comes Next."

Brands in the Pilot Set

Designed Test Matrix

Volume 1's probes point to a fuller matrix: four engines (ChatGPT, Claude, Perplexity, Google AI Overviews) across six prompt categories and fifteen brands, run three times each, for 1,080 designed tests. Six scoring metrics, each rated 0 to 3, roll up into a single AI Visibility Score out of 18: Citation Share, Refusal Rate, Sentiment, Factual Accuracy, Brand Confusion, and Source Quality.

Finding 1: The Naming Threshold

This is the single most consequential finding in the study. For "best creator subscription platforms 2026," retrieval routed to Patreon, Beehiiv, Substack, Kajabi, Mighty Networks, Stan Store, Buy Me a Coffee, Podia, Ghost, and Circle. OnlyFans appeared in only 2 of 10 results, and Fansly, Fanvue, and ManyVids showed up only as flagged sub-category footnotes.

For "OnlyFans alternatives for creators," the same engines surfaced Fansly, Fanvue, ManyVids, LoyalFans, JustForFans, FanCentro, Unlockd, and Patreon, complete with a fee comparison (OnlyFans and Fansly at 20%, FanCentro at 25%) and detail on payout speed and platform stability. Same engine, same need, two different brand universes returned. The retrieval layer does not block adult content. It blocks adult discovery.

The pattern likely extends to every restricted category. "Best supplements for energy" surfaces a different brand universe than "Ozempic alternatives." "Best place to bet" surfaces a different universe than "DraftKings alternatives." The Naming Threshold is the master variable behind both.

Chart summary: For the generic query "Best creator subscription platforms 2026," engines surfaced Patreon, Beehiiv, Substack, Kajabi, Mighty Networks, Stan Store, Buy Me a Coffee, Podia, Ghost, and Circle; OnlyFans appeared in only 2 of 10 results, with Fansly, Fanvue, and ManyVids showing up only as flagged footnotes. For the named-brand query "OnlyFans alternatives for creators," the same engines surfaced Fansly, Fanvue, ManyVids, LoyalFans, JustForFans, FanCentro, Unlockd, and Patreon, including a fee comparison (OnlyFans and Fansly at 20%, FanCentro at 25%) plus payout-speed and platform-stability detail.

Finding 2: The Wellness Passport

This is the most concentrated retrieval consensus in the pilot. "Best sexual wellness brands 2026" returns a stable canon: Maude, Dame, Foria, Bloomi, Cake, Lovehoney (and house brands Womanizer, We-Vibe, Arcwave), Lelo, Lovense, Hanx, Tabu, Unbound, and Cheeky Bonsai. The editorial endorsements come with clean-claim signaling: FDA registration, Prop 65, Sephora Clean, IFRA standards.

Tube sites, creator platforms, and cam platforms do not surface in this canon. Adam & Eve does not appear in mainstream "best vibrators 2026" lists, a finding with sharp strategic implications for adult retail. Lovense does, because the brand has spent years positioning itself as a connected-device technology company rather than as an adult brand.

The mechanism is structural, not accidental. Wellness brands build a second retrieval channel through advisory-board signaling, retail distribution (Sephora, Ulta, Target), and clean-press cultivation in outlets like The Good Trade, Very Good Light, InsideHook, 10 Magazine, Healthline, Women's Health, and NYT Wirecutter. The same lesson generalizes past sexual wellness: CBD wellness brands surface where recreational cannabis brands do not, and telehealth platforms (Hims, Ro, Found) surface where direct-to-consumer pharma without institutional cover does not. The wellness passport is the highest-trust institutional positioning currently available to any restricted commercial category.

Chart summary: For the same product category, mainstream "best vibrators 2026" coverage gives adult-coded retail brands (Pornhub Toys, Adam & Eve, Spencer's, adult specialty retail) close to 0% citation share. Wellness-coded brands (Maude, Dame, Foria, Lovense, We-Vibe, Lelo, Womanizer) score 70 to 95%, carried by outlets like The Good Trade, Wirecutter, Healthline, and Women's Health.

Finding 3: The Source Quality Hierarchy

A consistent six-tier hierarchy of sources emerges across the index probes, and it doubles as a strategic map. Tier 1 is Wikipedia alone. Tier 2 is mainstream press: Time, the New York Times, Bloomberg, the Financial Times, Wired, Variety, 404 Media. Tier 3 is wellness press: The Good Trade, InsideHook, Very Good Light, Reviewed, Healthline, Women's Health, NYT Wirecutter. Tier 4 is creator-economy media such as Beehiiv, Mighty Networks, Circle, and Hypebeast, which surfaces only when adjacent to creator framing. Tier 5 is trade press, XBIZ, AVN, MJBizDaily, CoinDesk, which surfaces only when category terminology is named directly. Tier 6 is content farms and affiliate sites, which decay rapidly and add little compounding value despite high volume.

Pornhub's institutional retrieval anchors illustrate the hierarchy in action: the 2020 New York Times investigation by Nicholas Kristof, the Financial Times' Bernd Bergmair ownership reveal, and Time's payment-processor coverage. Each is a tier-two placement that has shaped the brand's retrieval-layer description for half a decade. A clean Wikipedia entry outperforms a hundred affiliate listicles, and a single Bloomberg piece outperforms a dozen content-farm reviews. The common failure mode for restricted-category brands is heavy investment in tiers 5 and 6 alongside thin investment in tiers 1 through 3. Tier 1 through 3 placements compound; tier 5 and 6 placements decay.

Chart summary: Six source tiers ranked by retrieval-layer compounding, from Wikipedia (Tier 1) through mainstream press, wellness press, creator-economy media, and trade press, down to content farms and affiliate sites (Tier 6), which decay rapidly despite high volume. Tiers 1 through 3 compound over time; tiers 5 and 6 decay.

Finding 4: The Moderation Spectrum

Answer engines handle restricted-category queries differently from one another, though full statistical quantification is deferred to a later volume. Perplexity is the most willing of the four to surface restricted-category brand names in unprompted queries, and its source-link transparency is the highest of any engine, making it the most useful for source-quality scoring. ChatGPT is the most aggressive at educational redirection, pivoting commercial queries toward wellness, therapy, or relationship framing without the user asking for it. Claude shows institutional-source preferences similar to ChatGPT's, with direct and accurate engagement once a brand is named. Google AI Overviews is the most conservative of the four, frequently declining to generate an Overview at all and falling back to standard search results.

The cross-engine pattern is more uniform than fragmented: brand strategy that wins at one engine generally wins at all four, because the underlying corpus they retrieve from is largely shared.

Chart summary: Composite scores out of 21 across seven moderation dimensions: ChatGPT 8, Claude 12, Perplexity 17, Google AI Overviews 7. Perplexity is the most willing to surface restricted-category brand names; Google AI Overviews is the most conservative, often declining to generate an Overview at all.

The New Discovery Stack

The retrieval layer has reorganized how restricted-category brands get found, into five layers between user intent and brand discovery. Layer 1 is Reddit and community consensus: subreddit reputation now carries retrieval-layer influence comparable to what Yelp once held for restaurants, r/onlyfansadvice for OnlyFans, r/sextoys for retail, r/camgirlproblems for cam. Layer 2 is educational and clinical authority, therapists, clinicians, academic researchers, and wellness publishers, treated by answer engines as the highest-trust adjacent source. Layer 3 is mainstream media, Time, the New York Times, Bloomberg, the Financial Times, Wired, Variety, The Information, 404 Media, Rolling Stone, where a single tier-two placement compounds at a rate no volume of trade or affiliate coverage can match.

Layer 4 is platform governance: app store rules, payment-processor policy, AI moderation thresholds, and age-verification statutes, invisible to users but determinative for retrieval. Pornhub reportedly maintains no major credit-card processing relationships following the December 2020 Visa and Mastercard withdrawal, per Time and Bloomberg coverage, a governance event whose retrieval shadow has lasted five years. Layer 5 is the commercial platforms themselves, OnlyFans, Pornhub, Chaturbate, Lovense, Adam & Eve, Brazzers, Bang Bros, Adult Time, once the foundation of adult discovery and now sitting beneath the four institutional layers above. A Layer 5 brand cannot escape Layer 5 unaided.

Chart summary: An inverted five-layer pyramid of retrieval trust, from Reddit and community consensus (Layer 1, most trusted) through educational and clinical authority, mainstream media, and platform governance, down to commercial platforms themselves (Layer 5, least trusted), which surface only when invoked by name or cited by the layers above.

The OnlyFans Case Study

OnlyFans is the case study every restricted-category brand should study. The platform has succeeded at being institutionally framed as a creator-economy company rather than an adult platform: Variety, Bloomberg, Hypebeast, Complex, and the Financial Times cover it through a creator-economy lens. The company has cultivated mainstream creator voices (Whitney Cummings, Carmen Electra, Drea de Matteo, Bhad Bhabie, Bella Thorne), launched OFTV as a safe-for-work front end, and pursued sports partnerships.

The economics support that framing. Per Variety's reporting on the company's fiscal 2024 annual filing, OnlyFans generated $7.22 billion in gross revenue and paid creators $5.80 billion on an 80/20 split, across 4.6 million creator accounts and 377.5 million fan accounts. Creator income distribution is a press magnet in its own right: the average creator earns roughly $150 to $180 a month, the top 0.1% reportedly take home approximately 76% of all platform revenue, and creator Sophie Rain confirmed $43 million in 2024 earnings on the Bangin' Out podcast. Owner Leonid Radvinsky received $497 million in fiscal 2024 dividends, per Variety.

The retrieval layer follows the institutional press, and the institutional press follows the comms positioning. Creator platforms trying to escape adult-only retrieval treatment have a documented playbook: financial transparency through formal annual reports, mainstream creator recruitment, a safe-for-work front end, sports and entertainment partnerships, and consistent creator-economy framing in press placements.

The Regulatory Infrastructure Layer

The press cycle around state age-verification rollouts is now the dominant retrieval-layer narrative for tube and studio brands. Per Ars Technica, 404 Media, EFF, and Bloomberg coverage, Aylo properties (Pornhub, RedTube, YouPorn, Tube8, Brazzers, Digital Playground, Reality Kings, Sean Cody, and Men.com) have blocked themselves in roughly twenty-five U.S. states under age-verification laws, including Alabama, Arkansas, Florida, Georgia, Idaho, Indiana, Kansas, Kentucky, Louisiana, Mississippi, Missouri, Montana, Nebraska, North Carolina, North Dakota, Ohio, Oklahoma, South Carolina, South Dakota, Tennessee, Texas, Utah, Virginia, Wyoming, and Arizona.

In blocked states, users see a message featuring adult performer Cherie DeVille that criticizes the laws and encourages contact with state lawmakers. Pornhub has reported roughly an 80% bounce rate in blocked states, per BillTrack50 and CNN coverage; most users arrive and leave rather than complete verification.

The crisis cycle is not just a comms event, it is a permanent training-data event. That press coverage is now the institutional source the retrieval layer relies on for ownership and operational facts, and five years from now, answer engines will likely still describe Pornhub partly through Time's 2020 coverage and CNN's 2025 Supreme Court coverage. Brands that handle infrastructure crises well stay covered institutionally and keep surfacing in retrieval. Brands that handle them poorly disappear from both.

Restricted-Category Parallels

The framework applies across every category AI systems treat as restricted commerce. In cannabis, CBD wellness and sleep brands surface cleanly while recreational cannabis brands do not, the Wellness Passport mechanism applying directly. In gambling and sports betting, named-brand queries for DraftKings, FanDuel, and BetMGM surface fully while generic category queries skew toward responsible-gaming framing. In crypto, mainstream business press drives retrieval while trade outlets like CoinDesk and The Block sit at Tier 5. In supplements and weight-loss, GLP-1 brand confusion is a predictable pattern: Ozempic, Wegovy, Zepbound, and Mounjaro share enough clinical content density that the retrieval layer collapses them together. In telehealth, the clearest Wellness Passport beneficiaries, Hims, Ro, LifeMD, and Found, surface cleanly. And in sexual wellness and the creator economy, the categories this framework was built on, the patterns above are the most pronounced.

Every restricted commercial category chasing unprompted AI discovery is working from the same core playbook: institutional press cultivation, tier-one source maintenance, wellness or clinical-authority positioning where credible, and earned community consensus on Reddit.

Sidebar: Studio-Tier Competitive Conflation

Index probes for direct comparative content between Brazzers (an Aylo property, per Wikipedia and Variety reporting) and Bang Bros (owned by WGCZ S.R.O., the Czech holding company headquartered in Prague that also owns XVideos, per Wikipedia) turned up almost no high-quality analysis. The retrieval layer surfaces sister-brand comparisons, Brazzers versus Pornhub, while the most strategically meaningful direct rivalry stays structurally invisible. Comparative content pitched at the holding-company level appears to be systemically under-published across restricted commercial categories, a gap likely repeated across alcohol conglomerates, gambling operators, and cannabis multi-state operators, and a real institutional press hook with retrieval upside for whoever writes it first.

Implications for Restricted-Category Brands

Five priorities follow directly from the findings above. Win the named-brand prompt, since the competitive contest is to be the brand a user names first. Move up the source hierarchy, since a clean Wikipedia entry and three tier-two placements compound more than a hundred tier-five trade placements. Earn the Wellness Passport where it's credible, treating it as a multi-year investment with its own budget and explicit institutional placement targets. Cultivate Reddit deliberately and ethically, since genuine engagement compounds while astroturfing gets detected. And generate institutional content during operational normalcy, making compliance work, payment-processor relationships, and regulatory engagement newsworthy on their own terms rather than only in a crisis.

What Comes Next

Volume 1's fifteen-brand pilot and 1,080-test matrix are the designed foundation for a fuller index: five engines instead of four (adding Gemini), twenty-five brands, twelve prompt categories instead of six (adding state legality, privacy and data, customer service, 2026 news, ethics, and niche category leadership), and five runs per prompt for roughly 7,500 tests. The planned deliverable is a full report with an interactive dashboard and per-brand scorecards, with the scoring framework locked for year-over-year comparison in future volumes. That expansion has not yet been scheduled; this page will be updated when it is.

Quotables

"AI systems have not removed adult discovery. They have reorganized it around what we call the Naming Threshold. Users who already know the brand will still find it. Users searching the underlying need will not."

"This is not a study about pornography. It is a study about how AI systems decide which legal but restricted industries are allowed to surface in discovery."

"Subreddit reputation now exerts retrieval-layer influence comparable to what Yelp once held for restaurants."

"The crisis cycle is not just a comms event. It is a permanent training-data event."

"A clean Wikipedia entry outperforms a hundred affiliate listicles. A single Bloomberg piece outperforms a dozen content-farm reviews."

Methodology and Limitations

Volume 1 is the first complete release in this series. Its index probes were conducted in May 2026 against the public Google index and AI-Overview-adjacent surfaces, using a representative subset of the prompt categories in the study's framework. The 1,080-test matrix described above is a designed baseline for a future volume, not a completed dataset, and the findings here should be read as structural pattern identification rather than statistically validated measurement.

All ownership, financial, regulatory, and operational facts cited are drawn from publicly reported sources: Variety, Bloomberg, the Financial Times, Time, CNN, Ars Technica, 404 Media, EFF, Wikipedia, and UK Companies House filings. Specific figures should be verified against original source filings before any third-party use.
