How to Choose a GEO Agency: 12 Questions to Ask and 7 Red Flags (2026)

30-second checklist:

• Can they explain their method without buzzwords?
• Do they show a sample citation report?
• Do they refuse to promise citations?
• Is the contract three months or has a clean exit?
• Will you own the tracking accounts and data?
• Can they name a client in a similar business?
• Does their own business get cited by AI engines?

01What does a GEO agency actually do?

Generative engine optimization (GEO) is the practice of making your business easy for AI engines like ChatGPT, Perplexity, Gemini and Google AI Overviews to find, understand and cite. A GEO agency does that work for you. Digital Agency Network describes it as “3-4 services collapsed into one scope”, and a competent one covers six jobs:

1. 1
   Citation audit. Testing a set of buyer prompts across engines to see who gets named and which sources get cited.
2. 2
   Entity disambiguation. Making sure engines know exactly who you are, with consistent names, addresses, services and profiles.
3. 3
   Content restructuring. Rewriting pages so the answer comes first and each section stands alone.
4. 4
   Schema markup. Structured data that describes your business, services and FAQs.
5. 5
   Digital PR and third-party mentions. Directories, reviews, publications and forums that engines draw on.
6. 6
   Monthly tracking. Re-running prompts and reporting trends.

02GEO agency vs SEO agency vs freelancer vs in-house

Can an SEO agency do GEO? Sometimes. Google’s own guidance says there are no additional requirements to appear in AI Overviews or AI Mode beyond standard SEO, and a page must be indexed and eligible for a snippet. So strong SEO is the foundation. But ChatGPT, Perplexity and others pull from other sources, and the third-party mention work is different from link building. A good SEO agency can add GEO. A weak one will rename its existing report.

For most small businesses, an agency or a DIY start beats the fractional and in-house routes on cost. Our pricing guide covers the numbers in detail.

0312 questions to ask before you sign

Each question has a good answer and a bad one. Use them in calls and proposals.

Method

1. What’s your method, in plain English? Good: a clear sequence (audit, fix foundations, restructure content, build mentions, track). Bad: “proprietary AI” and a diagram with no steps.

2. How do you handle entity work versus keywords? Good: they describe consistent business data, schema, profiles and third-party corroboration. Bad: they only talk about keyword density.

3. How do you structure content for retrieval? Good: answer-first paragraphs, self-contained sections, clear headings, FAQs that stand alone. Bad: “we’ll publish 20 articles a month.”

4. Which engines do you track, and why those? Good: ChatGPT, Perplexity, Gemini and AI Overviews at minimum, chosen for your buyers. Bad: one engine only, or all of them with no reasoning.

Measurement

5. Can I see a sample citation report? Good: prompt lists, engines, brands named, cited sources, trends over weeks. Bad: a single visibility score or screenshots.

6. How do you attribute AI referrals? Good: GA4 segments for AI referrers plus lead-form questions like “how did you hear about us”. Bad: “AI traffic is hard to measure, trust us.”

7. What timeline is realistic? Good: MarketerHire’s range, baseline movement in 60 to 90 days and broader gains in 6 to 9 months. Bad: “citations in two weeks, guaranteed.”

8. How will you benchmark me against competitors? Good: a prompt set run for you and three named competitors, with a baseline written before work starts. Bad: no baseline at all.

Commercial terms

9. What’s the contract length and exit? Good: three-month pilot, then monthly. Bad: 12 months with a kill fee. Discovered Labs, itself a GEO vendor, says long lock-ins protect agencies from accountability, and we agree.

10. Is there a setup fee, and what do I get for it? Good: a written baseline and fix list. Discovered Labs says $3,000 to $5,000 for an initial audit is reasonable if it includes competitive benchmarking. Bad: a fee with no deliverable.

11. Who owns the accounts, prompt sets and data? Good: you do, and you receive exports. Bad: everything lives in the agency’s login.

Fit

12. Who’s a client like me, and can I talk to them? Good: a similar business type and region, with a reference call. Bad: only large-brand logos, or case studies with no named business.

047 red flags

1. 1
   Guaranteed rankings or citations. AI answers change from run to run and nobody controls them. A guarantee means either a hollow promise or a fee padded to cover the risk.
2. 2
   Google AI Overviews only. Google says no special optimisation is required for AI Overviews beyond good SEO, so a pitch built entirely around it misses ChatGPT, Perplexity and Gemini, which draw on different sources.
3. 3
   “Proprietary AI” with no human review. If the agency can’t say who edits the content and who checks facts, you’re buying mass-produced pages.
4. 4
   12-month lock-in with kill fees. Early GEO work is exploratory. You need an exit.
5. 5
   No citation dashboard. Manual-only monitoring means you can’t see trends. Ask what tools they use, and who owns the login.
6. 6
   Buzzwords and no explanation of retrieval. If they can’t describe in plain words how engines retrieve and cite pages, they’re guessing.
7. 7
   GEO sold as an SEO replacement. Strong fundamentals still matter. Google’s own guidance requires pages to be indexed and eligible for snippets before they can appear as AI supporting links.

05Scorecard: step by step to a shortlist

1. 1
   Define your goal and write 20 buyer prompts. Include “best [service] in [city]”, “[you] vs [competitor]” and cost questions.
2. 2
   Test each shortlisted agency’s own visibility. Ask ChatGPT, Perplexity and Gemini for the best GEO agency in their niche or city, then see whether they appear. Run it before you take the pitch call. Plenty of agencies selling GEO don’t show up for their own niche. An agency that can’t get itself cited is a warning sign. Not proof, but a signal.
3. 3
   Request a sample report and two references.
4. 4
   Compare proposals on deliverables, not hours. Count pages restructured, mentions pursued, prompts tracked, reports delivered.
5. 5
   Negotiate a three-month pilot with an exit. We favour three-month pilots with clear KPIs and client-owned accounts and data over 12-month lock-ins. It’s our policy, and we’d suggest you ask any agency for the same.
6. 6
   Agree KPIs. Citation rate, share of voice, AI referral sessions and leads.

06Pricing benchmarks (short version)

• Small business retainer: $1,500 to $5,000 per month (Nutshell, checked October 2026)
• Mid-market: $5,000 to $25,000 per month
• Audit or setup: $2,000 to $8,000 (Digital Agency Network)
• UK: retainers of £1,500 to £5,000 per month and audits of £3,000 to £8,000, reported by Gripped for B2B SaaS, with the first quarter costing 20 to 30 percent more

The detailed version, including what you get at each tier, is in our full GEO pricing guide. If you’re comparing tracking software before you hire anyone, see AI visibility tools compared.

07What to expect in the first 90 days

• Days 1-30: audit, baseline prompt test, technical and schema fixes, entity cleanup. You should have a written baseline by day 30.
• Days 31-60: content restructuring on priority pages, entity and third-party mention work begins.
• Days 61-90: first citations appear in some engines, the first full report compares against baseline.

A source cited by Discovered Labs, Lureon.ai, says first citations can land in two to four weeks. We’d treat that as the optimistic end. MarketerHire says 60 to 90 days for baseline movement on focused queries. Pipeline impact typically takes around 90 days, so hold the agency to leading indicators first and revenue second. For the ROI side, see our guide on measuring GEO ROI.

Why chase this at all? Pew Research found clicks on traditional results fell from 15% to 8% of visits when an AI summary appeared, and Semrush reports AI search visitors convert 4.4 times as well as organic ones.

08Special cases

Local service businesses and multi-location

Your game is consistent business data, Google Business Profile, reviews and local citations. For multiple locations, ask whether the agency builds a page and profile per location, not one page with a list of towns.

Ecommerce

Product data, reviews and comparison-page presence matter most. Ask how they handle product schema and which review sites they’d pursue.

Regulated sectors (health, legal, finance)

Claims need review. Ask who signs off content and how they handle regulators’ rules, such as the FCA in the UK or professional-body advertising rules. An agency that has never heard of them is a risk.

UK, Canada, Australia and the EU

Check that tracking and prompts respect data-protection rules (UK GDPR, EU GDPR, PIPEDA in Canada, the Privacy Act in Australia). Ask which local directories and publications they’d pursue, as US-only lists won’t help you. Also confirm they quote in your currency and whether VAT or GST applies.
