The 60-Second GEO Vendor Test
One question sorts the field: 'show me an AI answer your work changed' — dated, prompt visible. Practitioners produce it in minutes; performers schedule a follow-up call.
Authority Is the Half Most Agencies Skip
From the links perspective, the most common gap in GEO proposals is the authority layer. Plenty of agencies will audit your machine-readability and produce structured content, both genuinely useful, and then leave the trust question unaddressed — which means the work is a car without fuel, because generative engines cite sources they have reason to trust and that trust is earned through genuine mentions from credible places. The diagnostic question for any GEO proposal is therefore: how does month one build earned authority, from which named source types, at what honest pace? Agencies whose answer is a framework rather than named sources and a real outreach plan have skipped the half that determines whether the citations actually arrive. This is also why practitioners with a decade of genuine link-building behind them adapted to GEO faster than anyone who arrived with the trend — the authority discipline transfers directly, and it is the part that cannot be shortcut.
The Authority Test for Any GEO Proposal
From the links perspective, the single most diagnostic question for any GEO proposal is how month one builds earned authority, from which named source types, at what honest pace. Agencies with genuine practice name specific publications and describe real outreach; those without describe frameworks and roadmaps. Since citations rest on trust and trust is earned through credible mentions, an agency that cannot answer this concretely is proposing to do the preparation without the fuel. It is a single question and it separates the market more reliably than any other.
Reading a GEO Agency's Own Profile
A revealing check available to anyone: look at the agency's own authority profile and citation presence. An agency claiming to earn citations for clients should be visible in answers about its own category, and its own backlink profile should reflect the kind of earned credibility it proposes to build for you. Where it does not, that is worth asking about directly — sometimes there is a fair answer, and sometimes it reveals that the capability is aspirational. It costs fifteen minutes with free tools and it is one of the more diagnostic checks available.
Conclusion
The authority layer is what most miss — the free book covers it.
