The fastest way to tell a GEO agency apart from a good one is to ask exactly how they’ll prove their work is causing anything. If the answer is a citation count and nothing else, keep looking. Generative engine optimization — getting your business named or quoted inside ChatGPT, Gemini, Claude, and AI Overviews answers — is new enough that a lot of agencies pitching it are simply relabeling old SEO decks, and a lot of business owners don’t yet know which questions expose that.
We’re on the other side of these sales calls constantly, both pitching our own GEO packages and watching prospects describe pitches from other agencies before they choose us or someone else. The pattern is consistent: the agencies worth hiring can answer six specific questions without flinching. The ones repackaging SEO can’t.
How do they define success beyond “you got mentioned”?
A citation in an AI answer is not revenue. Ask directly: how will you connect visibility inside ChatGPT or Gemini to actual traffic, leads, or sales? A credible agency has a method for tracking referral patterns from AI platforms — even though the analytics tooling here is genuinely imperfect industry-wide — and talks about qualified traffic and conversion impact, not just how often your brand name shows up in a sampled prompt. If the answer stays at “we’ll get you cited more,” that’s a visibility vendor, not a growth one.
Do they treat GEO as separate from SEO, or built on top of it?
This is the single biggest tell. GEO that ignores your existing SEO foundation — your site structure, your existing rankings, your technical health — is being sold as a replacement for something it isn’t. In practice, the content and entity work that gets you cited by AI answer engines overlaps heavily with what gets you ranked in classic search; we covered the mechanics of that overlap in our breakdown of what GEO actually costs in 2026, and the pricing only makes sense once you see how much of the work is shared infrastructure rather than a bolt-on service. If an agency pitches GEO as a totally separate discipline requiring you to rebuild everything from scratch, ask why — the honest answer is usually that it lets them sell you a second full engagement.
Which AI platforms do they actually monitor, and why those?
“AI search” is not one thing. ChatGPT, Google’s AI Overviews, Gemini, Perplexity, and Claude all pull from different sources and weight signals differently. An agency that talks about “optimizing for AI search” as a single undifferentiated target either hasn’t done the work to understand the differences or is hoping you won’t ask. Push for specifics: which platforms do they track for your industry, how do they check citation patterns on each, and what changes when a platform updates its retrieval approach. If they can name platforms and explain the tracking method in one breath, that’s a good sign.
Can they show you real reporting, not just claims?
Ask to see an actual monthly or quarterly report template before you sign anything — not a case study slide, the real document a client receives. It should include early indicators (citation patterns, which prompts surface your brand, which pages get pulled into answers) alongside business outcomes further down the report (qualified traffic, conversions, and where possible, revenue influence). An agency that can only show you a screenshot of a citation-tracking dashboard, with no line connecting it to anything you’d actually care about, is going to leave you unable to judge whether the retainer is working six months in.
What does the engagement actually include?
Get specific about deliverables before you compare pricing between agencies, because “GEO package” means wildly different things depending on who’s selling it. At minimum, expect an initial audit, technical fixes where your site structure is blocking AI crawlers or confusing entity recognition, updates to your highest-intent pages (service pages, pricing, comparison content), answer-ready formatting of existing content, and ongoing monitoring as the AI platforms change their retrieval methods. If a proposal is thin on any of these and heavy on the word “strategy,” ask what specifically gets built or changed in month one.
What should you actually expect month over month?
Early visibility signals — your brand starting to appear in relevant AI answers — typically show up before any measurable revenue impact, and that gap is normal, not a sign the engagement is failing. Anyone promising fast, guaranteed citations or overnight ranking jumps in ChatGPT or AI Overviews is either misunderstanding how these systems work or hoping you won’t ask again in month two. Nobody — including agencies with excellent track records — controls what a language model decides to cite. What a good agency controls is the groundwork: structure, clarity, and consistency that makes citation more likely over time. We’ve laid out what a realistic month-by-month arc looks like in our look at agency pricing models, which applies just as directly to GEO retainers as it does to paid media ones — match the payment structure to how long results genuinely take to show up, not to how fast the salesperson wants to close.
What a red-flag pitch actually sounds like
It rarely announces itself as a red flag. It sounds confident, uses the right vocabulary, and often comes with a slide showing a client’s citation count climbing month over month with no baseline or context for what changed to cause it. Listen for phrases like “guaranteed placement in AI Overviews,” “we’ll get you into ChatGPT’s answers within 30 days,” or “GEO is completely different from SEO, forget what you know.” Each one is a shortcut around a question the agency doesn’t want to answer directly: nobody can guarantee what a language model chooses to surface, thirty days is not enough time for structural content changes to show up in retrieval patterns, and GEO’s actual mechanics — clear entity signals, structured content, answer-ready formatting — are extensions of good SEO practice, not a replacement for it.
A more subtle version of the same problem is the agency that answers every question well in theory but can’t point to a specific page on your site and say what they’d change first. Good GEO work starts with your actual content, not a generic framework applied identically to every client. If a proposal reads like it could be sent to any business in any industry with the company name swapped out, that’s usually because it was.
How this differs from vetting a traditional SEO agency
Most of the fundamentals carry over — check for transparency, real reporting, and realistic timelines regardless of what the service is called. What’s different with GEO specifically is that the measurement tooling is younger and less standardized industry-wide, which means an agency’s honesty about the limits of what they can currently track matters more than it would with a decade-old discipline like SEO. An agency that’s upfront about what’s still hard to measure in this space is, counterintuitively, more trustworthy than one with a suspiciously polished dashboard for a category that’s barely two years old in its current form. Ask how they’ve adapted their own reporting as the AI platforms themselves have changed, and listen for a real answer rather than a rehearsed one.
A quick pre-contract checklist
- They define success with both visibility metrics and business outcomes, not citations alone
- They explain how the work builds on your existing SEO rather than replacing it
- They name specific AI platforms they track and why those matter for your industry
- They’ll show you a real reporting template before you sign, not just a sales deck
- The deliverables list is concrete: audit, technical fixes, page-level updates, monitoring
- Nobody on the call promises guaranteed citations or a fast timeline
The same due-diligence habit applies whether you’re vetting a GEO specialist or a paid media partner — we wrote a near-identical checklist for vetting a paid media agency before you sign, and the overlap isn’t a coincidence. Good agencies in both categories are transparent about method and honest about timelines; the ones hiding behind buzzwords usually are in both categories too.
The bottom line
You’re not looking for an agency that promises the most. You’re looking for one that can explain, in plain language, how AI answer engines actually decide what to cite, how that connects to your SEO work, and what you should expect to see in month one versus month six. If a pitch survives all six questions above, it’s worth a serious look. If it wobbles on the first two, it’s a rebranded SEO retainer wearing a new acronym.
