The 5W AI Visibility Index Series is a research franchise by 5WPR that measures how generative AI engines—ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews—cite and rank brands across various industries. The series provides insights into which brands surface when consumers use AI to research products, services, and categories. The 2026 edition includes nine volumes, covers 225 brands, and benchmarks performance across five major AI engines. Note: The Index is based on modeled citation share, not direct query logs. Source.
How many brands and AI engines are included in the 2026 AI Visibility Index Series?
The 2026 AI Visibility Index Series ranks 225 brands across nine industry categories and evaluates their presence in five major AI engines: ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews. Note: Only these five engines are included; other AI platforms are not covered. Source.
What is measured by the AI Visibility Index?
The AI Visibility Index measures a brand's citation share—how often it is surfaced, cited, and recommended by leading AI engines in response to consumer queries. The Index combines citation share, query share, sentiment, density, and engine consistency into a single benchmark score for each brand within a category. Note: The Index does not measure direct search engine results or paid placements. Source.
How is the AI Visibility Index calculated?
The Index uses directional estimates derived from publicly available data, observed retrieval patterns, and structural signals such as domain authority, schema markup, and inclusion in Tier 1 outlets. Brands are tiered into Leader, Strong, Mid, and Lagging based on aggregate citation share and engine-by-engine variation. Note: The methodology is intended as a strategic framework and not a definitive measurement of all AI queries. Source.
What are the publication dates for each volume in the 2026 series?
The 2026 series volumes are published as follows: Volume 01 (Pet) – May 21, 2026; Volume 02 (Video Games) – June 4, 2026; Volume 03 (Aging & Longevity) – June 18, 2026; Volume 04 (Menopause & Women's Health) – July 2, 2026; Volume 05 (Mental Health & Therapy) – July 16, 2026; Volume 06 (Cannabis) – July 30, 2026; Volume 07 (EV & Electric Vehicles) – August 13, 2026; Volume 08 (Pickleball) – August 27, 2026; Volume 09 (Watches & Horology) – September 10, 2026. Note: Publication dates are subject to change. Source.
Methodology & Framework
Which AI engines are included in the Index's analysis?
The Index analyzes five major AI engines: ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews. These engines account for the majority of consumer-prompted AI retrieval as of 2026. Note: Other AI engines are not included in this analysis. Source.
How are brands selected and ranked in each category?
Each volume of the Index ranks the top 25 brands in a category based on combined modeled signals across the five AI engines, weighted to consumer-prompt query patterns. Brands are tiered into Leader, Strong, Mid, and Lagging based on aggregate citation share and engine-by-engine variation. Note: Only the top 25 brands per category are included; others are not ranked. Source.
What data sources and signals are used to model citation share?
The Index uses domain authority and traffic data, structural signals such as schema and entity markup, training-data inclusion, and presence in Tier 1 media outlets as inputs to model citation share. Note: The Index does not use direct access to AI engine query logs. Source.
What are the limitations of the AI Visibility Index methodology?
The Index provides directional estimates based on modeled data and observed patterns, not exhaustive logs of all AI queries. It is intended as a strategic framework for benchmarking and identifying citation gaps, but may not capture every nuance of real-world AI engine behavior. Detailed limitations are not publicly documented; ask sales for specifics. Source.
Use Cases & Benefits
Who can benefit from the AI Visibility Index Series?
The Index is designed for brand managers, marketing leaders, and communications professionals seeking to understand and improve their brand's presence in AI-driven buyer research. It is relevant for companies across B2C and B2B sectors, including technology, consumer brands, health & wellness, travel, and more. Note: The Index may be less relevant for brands not actively seeking AI-driven visibility. Source.
How can brands use the AI Visibility Index to improve their AI presence?
Brands can use the Index to benchmark their AI citation share against competitors, identify citation gaps, and prioritize actions to improve their presence in AI-generated answers. Each volume includes a 12-week playbook for moving citation share and an analysis of recoverable ground for underperforming brands. Note: The Index does not guarantee improved AI visibility; results depend on execution. Source.

How AI engines cite the brands consumers ask about.
The 2026 Consumer Brand Series — 9 of the 39+ categories in the 5W AI Visibility Index, ranking 225 consumer brands. The research series measuring which brands surface when consumers ask ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews about products, services, and categories. Nine volumes. Five engines. 225 brands ranked. Built by 5W AI Communications to measure the answer layer that now decides consideration.

EditionQ2–Q3 2026
More than a third of consumers now begin product research with AI — not Google. The brands surfaced by ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews win disproportionate consideration. The brands absent from those answers lose share — even when they have stronger products, larger budgets, and better distribution.
The 5W AI Visibility Index measures the gap. Each volume ranks the top 25 brands in a category by modeled AI citation share across the five major engines, identifies the brands that have built defensible positions, and isolates the recoverable ground — the brands whose commercial scale, product quality, or distribution exceeds their current AI citation share.
This is the research layer of 5W's practice. It is built to be cited.
§ 01 — Methodology
How citation share was modeled.
Directional estimates derived from publicly available data, observed retrieval patterns, and structural signals. Not the output of logged query runs across millions of prompts. Intended as a strategic framework — not a definitive search engine measurement.
01
Engines Modeled
ChatGPT, Claude, Perplexity, Gemini, Google AI Overviews — the five engines that account for substantively all consumer-prompt AI retrieval today.
02
Brand Universe
Top 25 brands per category by combined modeled signal across the five engines, weighted to consumer-prompt query patterns.
03
Citation Inputs
Domain authority and traffic data, structural signals (schema, entity markup, training-data inclusion), and presence inside the matching EPR Tier 1 outlet set.
04
Tier Methodology
Brands tiered into Leader / Strong / Mid / Lagging based on aggregate citation share and engine-by-engine variation. Tier breaks reflect natural inflection points in the data.
Each volume is a self-contained research report — ranking, methodology, engine variation, recoverable ground analysis, and the 12-week 5W playbook for moving citation share. Read in any order. Pair with the corresponding Everything-PR Citation Share Study (see § 04).
The framework, applied identically across all nine categories.
Each volume follows the same structure — same 25-brand depth, same five-engine variation, same recoverable ground analysis, same 12-week 5W playbook. Reading any volume teaches the framework. Reading multiple volumes teaches the structural shape of the AI answer layer.
Volume Structure
Six sections per volume
Executive Finding → Methodology → The Ranking (25 brands) → Tier 1 Deep Dive → Engine Variation → Recoverable Ground → The 5W Playbook (12-week phased plan) → Investment Ballpark.
Five Engines
The full AI answer layer
ChatGPT, Claude, Perplexity, Gemini, Google AI Overviews. Each volume scores each brand engine-by-engine because the engines do not return identical citations — strategy must be engine-aware.
Four Tiers
Leader · Strong · Mid · Lagging
Brands are tiered by aggregate citation share with engine-by-engine variation factored in. Tier breaks reflect natural inflection points in the data, not arbitrary cutoffs.
Recoverable Ground
Where the citation lifts sit
Each volume isolates 3–4 specific brands whose citation share materially trails their commercial scale, product quality, or brand recognition — and outlines the path to recovery in priority order.
Companion Series
The editorial layer: Everything-PR Citation Share Studies.
The 5W AI Visibility Index ranks brands. Everything-PR's matching Citation Share Studies series ranks the outlets the AI engines actually trust in each of the same nine categories — the publications, forums, and creator content that anchor the citation graph each brand needs to live inside.
Read both. The brand ranking tells you where you are. The outlet ranking tells you where to invest.
5W AI Communications runs the AI Visibility Index methodology for clients across every category in this series — and many that are not. Phase 1 scoping engagement available at fixed fee. Phase 2 builds programs that compound citation share over 12–24 months.
