Key Finding
Ecommerce: Average AIS Score of 24/100
Across all verticals tracked by AISearchStackHub in 2026, ecommerce brands consistently score lowest on LLM visibility. The structural reasons for this are well-understood — and fixable.
Why Ecommerce Scores Lower Than Any Other Vertical
The LLM citation problem for ecommerce is not a marketing problem. It is a content architecture problem. When language models are trained and fine-tuned on what constitutes a trustworthy, citable source, product description pages, category landing pages, and transactional content are almost never selected. These content types answer commercial intent — but they do not answer informational intent, which is what LLMs primarily serve.
Consider how someone uses ChatGPT, Perplexity, or Claude to research a purchase. They ask: "What are the best noise-cancelling headphones under $200?" or "How do I choose a standing desk?" These are informational questions that produce citations to buying guides, review roundups, comparison articles, and original research — not to product pages at brand.com.
Ecommerce brands have spent years optimizing for Google's commercial intent signals. PDPs ranked for "[product] buy online." Category pages ranked for "men's running shoes." That content is valuable for conversion but invisible to LLMs. The brand may have millions of indexed pages and still score a 14 on the AIS Index because none of those pages are the kind of source a language model would cite when answering a user question.
The average score of 24 is not a floor — several ecommerce brands in our dataset score above 50. But reaching that range requires a deliberate investment in informational content that most ecommerce teams have historically deprioritized.
Ecommerce Subcategory Benchmarks

Subcategory Analysis
Direct-to-Consumer (D2C) — Avg 28
D2C brands score better than the ecommerce average primarily because many publish brand narrative content — founder stories, mission pages, sustainability reports — that has modest citation value. However, D2C content is heavily weighted toward the upper and middle funnel with minimal informational depth.
The D2C brands scoring 40+ in our dataset share a common trait: they treat their blog as a research publication, not a product announcement channel. A mattress brand that publishes original sleep research. A nutrition brand that publishes macronutrient calculators with data. A skincare brand that publishes a peer-reviewed formulation transparency report. These assets earn citations in the way that standard D2C content never will.
Marketplaces — Avg 31
Marketplaces score highest in ecommerce because their sheer scale of user-generated content — reviews, Q&A threads, community posts — creates incidental informational content that LLMs occasionally surface. However, the signal is noisy and the authority attribution is diffuse. When Perplexity cites a marketplace, it is typically citing a review thread rather than the brand itself.
Marketplace operators looking to improve AIS scores should focus on their editorial and curation content: "Best of" lists with methodology, category buying guides, seller reliability reports, and market trend analyses. These position the marketplace as a knowledge source rather than a transaction destination.
Fashion & Apparel — Avg 21
Fashion scores the lowest of all ecommerce subcategories, and the gap between lowest and top quartile (8 to 38) shows how polarized outcomes are. Fashion brands are structurally disadvantaged: their product is visual, their content is seasonal, and their editorial voice — aspirational, trend-forward, brand-coded — is not the voice of an information source.
High-scoring fashion brands break from category convention. They publish: sustainability supply chain reports with auditor data, sizing standardization research comparing industry measurements, care and longevity studies showing how their materials age, and historical category analyses. This content is countercultural for fashion marketing teams, but it is precisely what earns LLM citations.
Electronics & Tech Hardware — Avg 26
Electronics brands sit in an awkward position: they deal in highly technical products that should generate citable content, but most brand content is spec-sheet focused. Spec sheets are not informational content — they are product documentation. A LLM answering "what is the best laptop for video editing" does not cite your spec comparison chart; it cites The Verge, Wirecutter, and Tom's Hardware.
To close that gap, electronics brands need to own the informational territory that third-party reviewers currently dominate. Use-case research ("average battery drain profiles for video editing workflows"), benchmark data published with methodology, and independent testing lab results cited on your own domain all shift a brand from "product page" to "reference source" in LLM training and retrieval.
Beauty & Wellness — Avg 29
Beauty and wellness brands score above the ecommerce average, but many are held back by a specific issue: health-adjacent claims. Language models are trained with careful guardrails around health content, and brands making strong efficacy claims — even well-documented ones — are often avoided as LLM citations precisely because the model does not want to be seen as endorsing health claims.
The beauty/wellness brands scoring 45+ in our data pivot away from efficacy claims toward formulation transparency, ingredient science explanations, and consumer research. A skincare brand that publishes "2026 Consumer Skin Health Survey: 1,200 respondents on ingredient comprehension" is providing value to LLMs answering consumer education questions — without putting the model in the position of endorsing a product.
What High-Scoring Ecommerce Brands Do Differently
Across all ecommerce subcategories, the brands scoring above 40 share a consistent pattern. They have made a deliberate choice to produce informational content alongside commercial content — and they have given that informational content its own resource center, distinct from the product catalog.
Buying Guides with Data
Not "here is why to buy our product" but "here is how to evaluate this category." Guides that include comparison methodology, measurement criteria, and numerical data get cited. Guides that are sales copy in disguise do not.
Original Research Reports
Surveys of 500+ customers or industry participants, published with full methodology and raw distributions. LLMs love citing original data. "According to [Brand]'s 2026 Consumer Survey..." is a citation pattern that appears repeatedly in high-AIS ecommerce brands.
Comparison Articles
"Brand A vs Brand B vs Brand C" comparison articles — including comparisons that do not always favor the publisher — build authority. When an electronics brand publishes a headphone comparison that includes competitors, LLMs start treating it as a reference source rather than a marketing page.
Statistics and Benchmark Pages
A dedicated "/statistics" or "/industry-data" page that aggregates key metrics for the category — with citations, methodology notes, and regular updates — becomes one of the highest-value citation assets in any ecommerce brand's library.
Glossaries and Explainer Content
Category terminology explained with depth and accuracy. Not a marketing fluff piece but a genuine educational resource. When users ask LLMs "what is [technical term] in [category]?", brands with comprehensive glossaries consistently appear.
Third-Party Validation
Wikipedia presence, Reddit community participation, HARO/journalist source relationship, and press coverage from editorial publications all increase the probability that LLMs surface a brand in citation-heavy queries. High-scoring ecommerce brands treat third-party authority as a parallel track.
About the AIS Index
The AIS (AI Search) Index is AISearchStackHub's composite scoring system for LLM brand visibility. Scores range from 0 to 100 and are calculated as a weighted composite across four dimensions:
- 40%Visibility (V) — How often the brand is mentioned across 24 standardized queries per engine
- 30%Authority (A) — The quality and trust level of citation sources
- 20%Structure (S) — Schema markup, content clarity, indexability for LLM retrieval
- 10%Ad Equivalence (Ad) — Estimated media value of organic LLM mentions
Scores are generated by sending standardized queries to ChatGPT (GPT-4o), Claude 3 Opus, Perplexity, and Gemini Pro, then analyzing mentions, citations, and source quality.
