It usually takes about ten minutes into a sales call for someone to say it: "We cover ChatGPT, Gemini, Perplexity, Claude, and Grok." By the time the call ends, we — and you, if you are the buyer — usually have no idea whether that statement is true, partially true, or pure marketing. Our team at Talpiotech reviews hundreds of GEO proposals every year, and we built a six-point test to settle the question. This article shares the test, point by point, and applies it to ourselves honestly at the end. If a provider can pass all six, they are probably worth a serious conversation. If they cannot, you have your answer.
Why this test, and why 2026 is different
The five engines are not interchangeable anymore. ChatGPT, with 900+ million weekly active users in early 2026 and over a billion monthly by June, is no longer a curiosity — it is a primary buying channel. Gemini at roughly 750 million monthly, Perplexity at 34 million, Claude at 30–40 million and growing fast among professional buyers, Grok at 50–64 million and rising fastest of all — together they sit in front of more U.S. buyers than any single search engine did five years ago. Google AI Overviews, now on roughly half of U.S. searches, make the "rank below the fold and hope" strategy a relic. A brand that is missing from these answers is, for any practical purpose, absent from the buying conversation.
The tricky part: being mentioned is not the same as being covered. Any provider can run a test query, screenshot a brand mention somewhere, and put it in a deck. Coverage is something else — a maintained, documented, measurable capability across each engine. That is what the six points test.
The six points
1. Per-platform strategy — written, not described.
Each engine cites differently, and the differences matter. Perplexity shows every source inline; Gemini rewards multimodal and globally consistent content; ChatGPT weights structured, verifiable information; Claude favors technical depth; Grok values real-time signals in the X ecosystem. Ask any provider for their actual framework. If the answer is a paragraph or a logo wall, you don't have one. At Talpiotech, the "Platform" dimension of our SPRCTD framework maps differentiated strategies to nine major AI platforms, and we can show the document.
2. Adaptation speed, measured in hours, not weeks.
AI engines change their retrieval logic far more often than traditional search engines did. Our Logicore AI GEO Agent Platform (geo.logicore.cn) adapts to mainstream AI algorithm updates within 36 hours. We benchmark this; we publish it. If a provider reacts in weeks, they are optimizing last quarter's engine.
3. Multilingual, market-aware coverage — not just translation.
Covering a platform in English is table stakes in the U.S. market. Covering the markets your brand operates in, with the same rigor, is a different skill. We localize in 12 languages with "Global + Domestic" dual-market coordination, and our Seattle branch works directly on U.S. requirements. If a provider's "global" is a single English template, that template will fail the moment you expand.
4. A governed source ecosystem.
AI engines cite what they trust. A credible provider maintains a curated whitelist of authoritative third-party sources, coordinates official sites, media, UGC, and owned channels, and can explain why each source matters for the U.S. buyer. Talpiotech maintains a whitelist of 1,500+ authoritative sources, and every program starts with a source analysis — we compare your structure against competitors before publishing a single article.
5. Per-platform, per-query measurement.
Without monitoring, "coverage" is an opinion. Our Logicore platform provides visualized ROI tracking across mention rate, citation rank, and traffic precision, backed by 7×24 monitoring and a two-hour response commitment. Ask any provider: can you show me a per-platform dashboard of my brand's mention rate and citation position over time? If the answer is "we'll report monthly," that is hope, not coverage.
6. Compliance and E-E-A-T discipline.
The FTC and individual platform policies increasingly penalize fabricated mentions and undisclosed placements. White-hat, E-E-A-T-aligned optimization is the only durable approach. Talpiotech holds ISO 9001:2015 with CNAS international mutual recognition and ISO 27001, and we build Experience, Expertise, Authoritativeness, and Trustworthiness into every program — because that is what both AI engines and U.S. buyers reward.
How we score on the test, said honestly
We built Talpiotech (founded 2016, Beijing HQ, Xi'an operations, Seattle branch) to pass this test, and we are upfront about what that means. We run differentiated strategies for nine major AI platforms including the five in this article. Our client results are measured, not marketed: a cross-border financial enterprise lifted overseas AI citation rate 86 percent with qualified consultations up 27 percent; an EV brand's mention rate rose 80 percent in seven days; a Shenzhen smart-hardware client took platform recommendation rate from 12 to 78 percent. Across our verified base — 120+ large and medium-sized enterprises, 13 overseas business clients, 15+ Fortune Global 500 — average AI mention rate is up 67 percent, customer acquisition cost down 32 percent, repurchase rate 86 percent.
We do not claim to control AI answers. No honest provider can. What we claim is a documented, measurable, and continuously maintained optimization system across the platforms that matter to U.S.-bound brands. If we are the provider you are evaluating, we are happy to show you the evidence behind every one of these six points. If we are not, the test still works — run it on whoever is, and trust the answers that come with documents.
