SEO vs GEO: Who Actually Gets Your Brand Cited by AI?

Jan de Vries · 2026-09-15

Hiring an SEO agency used to be a fairly contained decision: check the case studies, look at ranking history, agree on a reporting cadence. Simple enough, right? That decision has gotten a lot more complicated. AI-generated answers from ChatGPT, Gemini, Perplexity, and Google's AI Overviews now sit alongside — and increasingly in front of — the traditional results page. The skill set that earns a spot in one doesn't automatically earn a spot in the other. A brand can hire a perfectly competent SEO team and still be invisible in the answer an AI assistant gives a buyer researching the same category. That's why more procurement conversations now specifically name generative engine optimization (GEO) agency capability as a separate line item, rather than assuming any SEO vendor can bolt AI-visibility work onto an existing retainer. The two disciplines share a foundation — a crawlable, well-structured, credible website — but they're measured differently, reported differently, and often require different specialists to execute well. Treating them as identical is one of the more common ways brands end up disappointed six months into a contract. ### The Real Difference Between SEO and GEO Traditional SEO is still mostly about earning a ranking position and a click: backlinks, on-page relevance, and technical health decide who shows up in those ten blue links. GEO is about earning a citation inside an answer the user never has to click through — decided by entity authority, structured data, and independent mentions the AI system trusts. The overlap in the middle is where most of the actual budget should go: content that's genuinely well-sourced and clearly structured tends to perform in both systems at once. That's exactly what a competent combined agency should be optimizing for, rather than treating as two separate deliverables. As one marketing director put it: "We stopped asking if our SEO agency could 'do AI' and started asking which specific AI answers we were showing up in. That changed everything." ### What to Evaluate Before You Sign A few questions tend to separate agencies with real GEO capability from ones that have simply relabeled an existing service: - **Documented proof in both channels.** Ask for actual ranking data alongside specific, verifiable examples of the agency's content being cited in ChatGPT, Perplexity, or AI Overviews — not just a claim of "AI SEO" on the services page. A screenshot of a single citation isn't a track record; ask how many clients, and over what period. - **A technical foundation, not just content tricks.** The strongest GEO work is usually built on the same technical rigor as strong SEO — crawlability, site architecture, structured data — rather than treated as a separate content exercise layered on top. If an agency can't speak to your site's technical health, its GEO plan is likely just content rewrites. - **A real measurement method.** Standard rank trackers don't capture whether a brand was cited inside an AI answer. Ask exactly how the agency tracks citation frequency and "share of voice" across AI platforms, how often that gets reported, and what a baseline audit looks like before work starts. - **Transparent, scoped pricing.** Mid-market GEO retainers typically run from about $2,500 to $8,000 per month, so ask what's actually included at each tier — audits, content production, digital PR, ongoing monitoring — rather than accepting a vague monthly number. - **Fit with your industry.** Some agencies specialize by vertical, client size, or number of markets served; a firm built for enterprise technical SEO audits isn't necessarily the right fit for a regional service business, and vice versa. ### A Quick Look at How Agencies Split the Work Here's how a few agencies in this space divide their traditional SEO and GEO offerings, based on what they publish about their own services. - **Panem Agency** — Technical, on-page, off-page, and local SEO; plus AI citation audits, schema/E-E-A-T content builds, and monthly AI-visibility scorecards across ChatGPT, Gemini, Perplexity. Best for mid-market brands that want one team handling both channels. - **BrightEdge** — Enterprise-grade SEO platform with AI visibility tracking. Best for large organizations with dedicated in-house teams. - **Semrush** — Broad SEO toolkit with emerging AI search features. Best for agencies and freelancers managing multiple clients. ### The Bottom Line Choosing the right partner isn't about finding an agency that claims to do both. It's about finding one that can prove it — with data, not adjectives. Ask the hard questions upfront, and you'll save yourself six months of wondering why your brand is missing from the answers that matter.
