- **Physio-Pedia**: Clinical authority on load, stability, and rehab framing—wins non-transactional prompts Amazon cannot own.
- **Garage Gym Reviews**: Independent comparison format that matches buyer questions; becomes the default third-party shortlist in AI answers.
- **FluidX**: Dedicated water-resistance brand narrative plus training content; AI can cite one domain for both product and method.

## Diagnosis

AI search visibility is about intercepting category queries before buyers decide what to purchase. For Tidal Tank, that visibility sits at a low 16.25% (CI: 9.75% to 25.84%). Worse, you are only securing 9 direct citations across 80 searches.

Why? Because answer engines favor domains that provide definitive, structured answers to the questions buyers are actively asking. Right now, when users ask about unstable loads or water vs. sand, engines cite Physio-Pedia (12 citations) for clinical framing or Garage Gym Reviews (8 citations) for head-to-head comparisons. Buyers rely on these third parties. As one r/homegym user noted, "Check Garage Gym Reviews before you buy any specialty bag—most of these brands look the same until you read long-term notes."

Your direct competitor, FluidX, is capitalizing on this. They pair product specs with exercise education, giving engines a single citable brand and method source. Meanwhile, Tidal Tank relies on thin schemas (only Organization and WebSite), leaving your pages structurally inadequate for AI citations. This friction pushes buyers to easier alternatives. Another r/homegym user stated, "I wanted Tidal Tank specifically but ended up ordering a generic aqua bag off Amazon same day."

To reclaim this lost market share, Tidal Tank must publish a unified, citation-grade hub. By deploying Product, FAQPage, and HowTo schemas, improving your PageSpeed from 66, and routing your existing llms.txt file to pages that tackle the exact water-vs-sand questions buyers ask, you can replace Amazon and FluidX as the definitive source for AI search engines.

## Technical readiness

- AI crawlers can read the site: OK. No AI crawler is blocked in robots.txt.
- llms.txt: OK. Present, plus llms-full.txt.
- Structured data (JSON-LD): Weak. Only Organization, WebSite. Nothing says what you sell or answer.
- Homepage description: Weak. Empty. Search engines write their own snippet.
- agents.md: Note. Optional. Very few sites have one yet.

## Method

80 answers: 5 buyer questions × 4 samples × 4 engines, sampled through the engines' APIs with web search on (ChatGPT: unknown, Claude: unknown, Gemini: unknown, Perplexity: unknown). A "mention" is the business named in the answer text; a "citation" is its own URL linked as a source. The two are counted separately. Rates carry 95% Wilson score confidence intervals. Reviewed by hand before publishing.
