Generative engine optimization is one of the fastest-growing disciplines in digital marketing – and one of the most misrepresented. Most agencies slapping “GEO” on their service pages are repackaging old SEO tactics. Before you sign a contract, here’s how to tell the real players from the pretenders.
The Questions You Should Be Asking
Don’t start with pricing. Start with proof.
Ask every candidate these questions directly:
- “Which AI engines do you optimize for – and how?” A credible answer names Google AI Overviews, ChatGPT, Perplexity, and Gemini separately. Vague answers about “AI search” signal surface-level knowledge.
- “How do you build a priority prompt set for a client?” GEO starts with mapping the exact queries your buyers type into AI tools. If they don’t have a process for this, they’re guessing.
- “Can you show a before/after citation audit?” Real GEO work produces measurable changes in how often a brand is cited or mentioned in AI-generated answers. Ask for documented evidence.
- “How do you track AI referral traffic?” Sessions from Perplexity, ChatGPT, and Gemini show up in analytics. Any agency doing real work knows exactly where to find them.
Red Flags to Watch Out For
Some are obvious. Others aren’t.
Walk away if they:
- Pitch GEO as “just like SEO, but for AI” – it shares principles, but the mechanics, measurement, and content strategy are fundamentally different.
- Can’t explain entity optimization or structured content beyond “use headers and bullet points.”
- Promise guaranteed placements in AI answers. No one controls what a generative model cites. Anyone claiming otherwise is lying.
- Offer GEO as a bolt-on to a standard SEO retainer with no dedicated methodology or tooling.
- Show you traffic reports but can’t break down AI-sourced sessions from organic search sessions.
The subtler red flag: they talk exclusively about Google. ChatGPT and Perplexity now drive meaningful referral traffic in B2B categories. An agency ignoring them is already behind.
What a Legitimate GEO Engagement Looks Like
A real GEO engagement starts with a baseline audit – not content creation.
Before any optimization work begins, you should receive a clear picture of where your brand currently stands across AI engines: how often you’re mentioned, in what context, and against which competitors.
From there, the work is structured around three pillars:
- Content architecture – restructuring existing pages so AI models can extract clean, citable answers.
- Entity and authority building – ensuring AI systems associate your brand with the right topics, credentials, and use cases.
- Prompt coverage expansion – systematically increasing the number of buyer-intent queries where your brand appears in AI responses.
This is iterative work. Expect monthly cycles, not one-time deliverables.
The Deliverables You Should Expect
At minimum, a serious GEO partner delivers:
- Baseline AI visibility audit across target engines and priority queries
- Priority prompt set mapped to your product categories and buyer journey stages
- Content optimization briefs tied to specific citation gaps
- Monthly share-of-voice reporting showing your mention rate versus competitors
- AI referral traffic tracking integrated into your existing analytics setup
If a proposal doesn’t include all five, ask why. Missing deliverables usually mean missing capability.
How to Measure Success
AI visibility isn’t vanity. It connects directly to pipeline.
Track these metrics from day one:
- Mention rate: how often your brand appears in AI answers for your priority prompts
- Citation quality: whether AI tools link to or quote your actual pages
- Share of voice: your citation share versus named competitors across target queries
- AI referral sessions: traffic from ChatGPT, Perplexity, Gemini, and AI Overviews in your analytics
- Downstream conversions: leads and assisted conversions originating from AI-driven sessions
A Princeton University study published at KDD 2024 found that structured GEO methods can improve content visibility in generative engine responses by up to 40%. That’s the ceiling – but only with the right execution partner.
Choosing the right partner matters more in GEO than in almost any other channel, because the field is moving fast and the gap between good and mediocre work compounds quickly. If you want a benchmark for what a serious practice looks like, Crescendo is a generative engine optimization company built specifically around this discipline – worth reviewing before you finalize your shortlist.
