How to read these numbers
Mention share is the percentage of all logged brand mentions belonging to a brand — a measure of AI mindshare, not company size or quality. A brand can dominate classic advertising and still be invisible here, because engines weigh different signals: indexability, answer-ready content, corroboration, freshness. That gap — big brand, low AI visibility — is exactly what the index exists to expose.
Run date matters: this is a 2026-07-09 snapshot. Engines re-ground constantly, which is why editions are dated and why monthly monitoring exists.
Your business against this data
National brands set the ceiling; your local market is the actual battlefield — and the published Houston metro study found a median AIR Score of just 31/100. Get your free scan to see your own five-engine baseline, and read the methodology for exactly how these numbers are produced.
Frequently asked questions
Why does the full table live on deepaivisibility.com instead of here?
One dataset, one home: the live index at deepaivisibility.com is the interactive, always-canonical dataset with every brand, engine breakdown, and run log. This site is the published editorial summary — headline findings, methodology, and context — so the numbers can never drift between two copies.
Were any brands paid to appear or excluded?
No. The 46 tracked brands were selected as the recognizable national players in HVAC and plumbing before the run; measurement is prompt-in, response-logged, mention-counted. Eight of them earned zero mentions — they stay in the data because absence is a finding, not an embarrassment to hide.
Does 10.0% mention share mean Roto-Rooter is the best plumber?
No — it means Roto-Rooter is the most AI-visible plumbing brand: when five engines answered 38 buyer-intent prompts, 10.0% of all brand mentions were Roto-Rooter. The index measures visibility, not service quality. Conflating the two is exactly the kind of claim the methodology page warns against.
When is Edition 02?
Upcoming editions extend to more verticals and metros, each shipping with its own dated run and methodology stamp. Businesses that get scanned join the measurement base — the free scan at deepaivisibility.com is the entry point, and no edition will ever include pay-for-placement.
Can I cite these numbers?
Yes, with the date: 'Roto-Rooter led AI mention share at 10.0% (AI Visibility Index Edition 01, measured 2026-07-09, Deep AI Solutions).' Link either this page or deepaivisibility.com/ai-visibility-index. The dated citation matters because engines shift and editions supersede each other.
