  "snapshotDate": "2026-06-07",
  "method": "20 GTM buying-intent queries (derived from the 30-tool AI GTM Tools index taxonomy: marketing, seo-geo, sales verticals) were each submitted to three AI answer engines: Perplexity (default web search), ChatGPT (GPT-5.x, web-search enabled), and Google AI Overviews (default Google Search). For each answer we logged (1) the tools named/recommended in order, and (2) for Perplexity, the full list of cited source URLs (Perplexity exposes a native numbered source list; ChatGPT renders citations as in-product chips and Google AI Overviews collapses its citation list and intermixes it with organic results, so citation-source autopsy rests on Perplexity's high-fidelity capture while cross-engine divergence uses the tool-recommendation lists from all three). Source-type classification was performed from domain signatures; one cited page (zapier.com) was visited and coded directly as a structural exemplar (Article+BreadcrumbList schema, comparison table, pricing data, 2026 freshness, ~2,600 words).",

  "headlineFindings": {
    "redditDominance": "Reddit was cited in 15 of the 20 Perplexity answers (75 percent), the single most-cited domain. No other domain appeared in more than 30 percent of queries (zapier.com 30 percent, youtube.com 25 percent).",
    "thirdPartyShare": "Roughly 4 in 5 Perplexity citations pointed to third-party pages (independent roundups, review blogs, comparison aggregators, and forums) rather than to the recommended vendor's own site. AI recommends the tool but cites someone other than the tool to justify it.",
    "crossEngineDivergence": "Across the 14 category and intent queries, the three engines named the same top tool on only 5 (36 percent), agreed 2-of-3 on 6 (43 percent), and named three different top tools on 3 (21 percent). All three full-divergence queries fall in the GEO / AI-search-visibility category.",
    "geoIsUnsettled": "On mature categories the engines converge on one winner (Apollo for prospecting, Clay for enrichment, Surfer for SEO optimization, 11x for AI SDR, all named top by 2 or 3 engines). On the GEO / AI-visibility category itself the engines disagree, naming largely different tools, meaning that category is still contested and visibility there is winnable.",
    "aioTriggerRate": "Google AI Overviews rendered on 19 of 20 queries (95 percent); the one miss (best AI SDR tool 2026) had shown an overview on an earlier probe, illustrating AI Overview trigger volatility.",
    "indexValidation": "7 of the 8 tools named as a top recommendation by two or more engines are S-tier in the companion 30-tool AI GTM Tools index (Apollo, Clay, Surfer SEO, Profound, Otterly, Smartlead/Instantly, Jasper), an external check on the index's merit placements."
