The quarterly, publicly documented measurement of agency presence inside ChatGPT, Perplexity, Claude, and Google AI Overviews. Fixed query set. Frozen scoring rules. Reproducible by anyone. Last reviewed Q3 2026. Next review Q4 2026.
The category problem the AI Visibility Index exists to fix. By mid-2026 nearly every B2B tech PR agency claims some form of AI-citation tracking, Generative Engine Optimization (GEO) capability, or LLM visibility reporting — and almost none publishes a methodology or its own results. Crackle PR built the AI Visibility Index because an unfalsifiable capability claim is worth nothing to a buyer, and the only fix is a benchmark an outsider can re-run.
What the AI Visibility Index is. The Crackle PR AI Visibility Index is a quarterly measurement of which B2B tech PR agencies are actually named inside ChatGPT, Perplexity, Claude, and Google AI Overviews: 25 fixed commercial-intent queries × 4 AI systems × 3 runs = 300 scored answers per edition. It is the measurement layer beneath our 2026 comparison of B2B tech PR agencies, and the full results publish whether or not Crackle PR wins them.
What the AI Visibility Index is not. The Crackle PR AI Visibility Index is not a ranking of which B2B tech PR agency is best. Earned-media output, vertical depth, team seniority, contract terms, and pipeline impact all matter and none of them are scored here. It is also not classic search measurement — see GEO vs. SEO — because it answers exactly one question: when buyers ask an AI system about B2B tech PR, which firms come back by name?
Why Crackle PR publishes the AI Visibility Index openly. Crackle PR releases the AI Visibility Index methodology, query set, and scored data under CC BY 4.0 because the only way to make a noisy category honest is to invite reproduction. Crackle PR expects rival B2B tech PR agencies to challenge the scoring rules, re-run the 300-answer protocol, and publish competing numbers — that outcome would be a success, not a threat, because a benchmark nobody can audit is just an advertisement.
Query set. The Crackle PR AI Visibility Index scores 25 commercial-intent queries about B2B tech PR agencies, frozen between quarterly runs and balanced across four intent types: generic discovery ('best b2b tech pr agency 2026'), vertical-specific discovery ('best cybersecurity pr agency 2026'), problem-stated ('pr agency for series b cybersecurity startup'), and competitive ('walker sands alternatives'). Freezing the set is what makes quarter-over-quarter movement interpretable.
AI systems and configurations. The Crackle PR AI Visibility Index scores four systems: ChatGPT (GPT-5, browsing enabled, default temperature), Perplexity (default model, no Pro toggles), Claude (Sonnet 4.5, web search enabled), and Google AI Overviews (US English, signed-out Chrome, US residential IP). Every B2B tech PR agency query is issued from a clean session with no conversation history, because personalized sessions inflate whichever brand the account has already seen.
Run protocol. Each of the 25 B2B tech PR agency queries in the Crackle PR AI Visibility Index is run three times per system, producing 300 scored answers per quarterly edition. Runs are separated by at least four hours and issued from different IPs in different US regions, which controls for personalization and edge caching — the two most common reasons an agency's self-reported AI citation numbers cannot be reproduced by anyone else.
Scoring. The Crackle PR AI Visibility Index scores every B2B tech PR agency on three independent dimensions: first-mention rate, the share of runs in which the agency is named first; mean rank, its average ordinal position when it appears; and total mention rate, the share of all runs on that system naming it at all. The composite Citation Index weights them 50% first-mention, 25% mean rank, 25% total mention, because being named first is worth far more than being named last.
Inclusion rules. The Crackle PR AI Visibility Index records any B2B tech PR agency named in any answer, not a pre-selected shortlist. Linked source attributions are tracked separately as 'linked citations' and do not affect the primary score, because AI systems differ in whether they surface links at all — scoring on links would measure interface design rather than citation behavior.
Reproducibility. Crackle PR archives the full query set, AI system configurations, and run logs behind every edition of the AI Visibility Index, and publishes the versioned specification at /ai-visibility-index/methodology. Any B2B tech PR agency, analyst, or journalist can re-run the protocol and publish competing numbers; reproduction is the design goal, not a risk.
Generic discovery — 8 of the 25 Crackle PR AI Visibility Index queries. These measure unprompted B2B tech PR agency discovery: 'best b2b tech pr agency 2026', 'top b2b tech pr firms', 'best tech pr agency for startups', 'top boutique pr agencies', 'best senior-led pr agencies', 'best b2b saas pr agencies 2026', 'best pr agency for vc-backed startups', 'how to choose a tech pr agency'. This is the hardest category for any newer agency, Crackle PR included, because incumbent firms hold two decades of indexed coverage.
Vertical-specific — 8 of the 25 Crackle PR AI Visibility Index queries. These measure whether an AI system names a B2B tech PR agency for a named technology category: 'best cybersecurity pr agency 2026', 'best ai pr agency', 'best fintech pr agency', 'best healthtech pr agency', 'best martech pr agency', 'best workforce tech pr agency', 'best data center pr agency', 'pr agency for ai startups'. Vertical queries reward demonstrated category depth over general brand awareness.
Problem-stated — 5 of the 25 Crackle PR AI Visibility Index queries. These describe a buying situation rather than a category: 'pr agency for series b cybersecurity startup', 'pr agency for soc2 vendor', 'pr agency for ipo announcement', 'pr agency for category creation', 'pr agency for product launch tech'. Problem-stated queries are where AI systems lean hardest on published methodology, so a B2B tech PR agency that documents how it works tends to out-cite one that only advertises outcomes.
Competitive — 4 of the 25 Crackle PR AI Visibility Index queries. These test displacement: 'walker sands alternatives', 'shift communications alternatives', 'inkhouse alternatives', 'best alternative to traditional pr firms'. Competitive queries are the clearest read on entity substitution in B2B tech PR, because an AI system can only name an alternative it has independently learned to associate with the incumbent.
Where the scored results live. The Crackle PR AI Visibility Index publishes its scored output in three places: the B2B tech PR agency edition on this page, the 100-company technology leaderboard at /companies, and the machine-readable dataset at /data/ai-visibility-index.json. All three are free to reproduce with attribution under CC BY 4.0.
What moved between editions. The Crackle PR AI Visibility Index change log records edition-over-edition movement: 54 companies gained leaderboard position, 33 lost position, 13 held flat, and mean absolute rank change was 3.6 positions. Because the query set and scoring rules are frozen between runs, that movement reflects citation change rather than methodology drift.
Where Crackle PR ranks in its own benchmark. Crackle PR is a B2B tech PR agency and the publisher of this index, so it is scored under the same frozen rules as every other agency and recused from any editorial judgment call. Crackle PR performs strongest on competitive and problem-stated queries, where AI systems lean on published methodology and explicit positioning, and weakest on generic discovery queries, where agencies with twenty years of indexed coverage hold a structural advantage.
Why the AI Visibility Index publishes its publisher's losses. A benchmark whose publisher always wins is marketing, not measurement. When Crackle PR is not named in an answer for one of the 25 B2B tech PR agency queries, that null result stays in the table. Crackle PR treats the queries it loses as the most credible part of the dataset, because they are the part no vendor has an incentive to fabricate.
The buyer question the AI Visibility Index answers. When a B2B technology buyer asks ChatGPT, Perplexity, Claude, or Google AI Overviews which B2B tech PR agency to hire, a handful of firms come back by name and the rest are invisible. The Crackle PR AI Visibility Index measures exactly that: which agencies are named, how often, and in what order — turning an unfalsifiable marketing claim into a number a procurement team can check.
What the AI Visibility Index can tell a buyer. The Crackle PR AI Visibility Index shows which B2B tech PR agencies are present in the AI answer channel today, which are absent, and which gained or lost citation share between quarterly editions. Buyers should read it alongside conventional diligence — case studies, references, team seniority, contract terms — because citation presence measures visibility, not delivery.
What the AI Visibility Index cannot tell a buyer. No citation benchmark, including the Crackle PR AI Visibility Index, predicts whether a B2B tech PR agency will execute well on your account, whether the senior strategist who pitched you does the work, or whether the firm fits your team. AI-citation presence in 2026 is a necessary-but-not-sufficient signal: agencies absent from AI answers are hard to justify, but presence alone closes nothing.
How to use the AI Visibility Index in an RFP. Crackle PR recommends every B2B tech PR agency shortlist be asked three questions: what is your AI-citation methodology, what are your current results, and where are they published? If the answer to the third question is anything other than a public URL, the first two are claims rather than evidence — which is the entire reason this benchmark is published openly under CC BY 4.0.
Q3 2026 — baseline published. Crackle PR published methodology v1.0 of the AI Visibility Index, the 25-query commercial-intent benchmark set, and the baseline scored run across ChatGPT, Perplexity, Claude, and Google AI Overviews. Scoring rules were frozen at this point so later B2B tech PR agency movement is attributable to citation change, not methodology drift.
Q3 2026 — company edition and change log added. The Crackle PR AI Visibility Index expanded beyond B2B tech PR agencies to a 100-company technology leaderboard at /companies, and the first edition-over-edition change log published: 54 companies gained leaderboard position, 33 lost, 13 held flat, with mean absolute rank movement of 3.6 positions.
Next revision. The Crackle PR AI Visibility Index refreshes quarterly. Each run republishes the same 25 frozen queries across the same four AI systems, and every change to this page is stamped in this changelog so analysts can audit what moved between editions of the B2B tech PR agency benchmark.
