How do you choose a GEO agency for a SaaS company?
Pick the agency whose evidence matches your situation: your stage, the buyer questions you need to win, and how you will judge success. Six criteria do most of the work.
Shortlist agencies that publish SaaS results on their own site, then choose the one that can name the buyer questions it would win for you, show how it will measure them, and explain how that work reaches pipeline. Price and contract length come after those three.
IThe six criteria
1. They start from your buyers' questions
AI engines answer questions, so the work should start from the questions your buyers ask before they buy: "best tool for X", "X vs Y", "how much does X cost". An agency that opens with a list of keywords or a content calendar has skipped that step.
2. Their proof is on their own site
When we tracked how AI engines answer "best GEO agency for B2B SaaS" in October and November 2026, the engines did not stop at listicles. They searched for each agency's own case study pages to check the numbers. Do the same: open the case study, check the client is a company like yours, and see whether the result is about AI answers or only Google traffic.
3. They work where AI engines actually look
Answer engines quote your site, but also comparison articles, review sites, forums and communities, and videos. Ask which of those the agency works on, and which it leaves to you. The original GEO research found that changes to how content is written can raise a source's visibility in generative answers by up to 40% (Aggarwal et al.), but on-page changes are one lever among several.
4. They separate branded from unbranded questions
Being named when someone asks about your brand is easy. Being named when a buyer asks "which tool should I use for X" is the job. Ask for both numbers, reported separately.
5. They can connect visibility to pipeline
AI answers send fewer clicks than search used to, and many buyers search your name later. Ask how the agency will show you that the work produced visits, signups, demos or revenue. See how to measure GEO.
6. The engagement fits your stage
Minimum terms and price floors vary widely. A Series A company with a two-person marketing team needs an agency that ships most of the work itself and asks for little of your time. Compare published prices and ask how many hours a month they need from you.
IIQuestions to ask on the first call
- Which ten buyer questions would you track for us first, and why those?
- Today, which agencies or competitors do AI engines name on those questions, and which pages do they cite?
- What do you change in month one, and what do you need from us to do it?
- Which sources do you work on beyond our website?
- How will we know it worked, in visibility and in pipeline?
- Can I read a case study for a company at our stage, on your own site?
- What happens to the work if we stop after the minimum term?

Common questions
What is the single most useful question to ask a GEO agency?
Ask which buyer questions they would track for you in month one, and how they will show you whether AI engines name you on those questions more often than before. A concrete answer shows they work from your buyers' questions. A vague one usually means reporting on mentions in general.
Should a GEO agency guarantee results?
No agency controls what ChatGPT, Perplexity or Google's AI answers say. Treat guarantees of rankings or citations as a warning sign. Good agencies commit to the work they control and report the outcome honestly.
How long before GEO work shows results?
Technical fixes and on-site changes can show up within weeks, while earning citations on third-party pages and communities takes longer. Ask each agency for its own timeline and what you should see at each step.
Do I need a SaaS specialist?
It helps when your buyers ask technical or comparison questions, because the agency already knows which pages and communities those buyers trust. A generalist with strong SEO can still work if they show SaaS examples.
