How to Choose a GEO Agency: The Decision Framework for Marketing Leaders

by Streamline
by Streamline

There’s a moment in every hiring decision where you need to actually commit. You’ve done research, talked to agencies, gathered information. But at some point you have to go with your gut and make a choice. And the question is: what does a good gut decision look like in this case?

I want to give you a framework that walks you through the decision methodically, because choosing the wrong partner can cost you six months of wasted time and budget. Choosing the right partner can genuinely change how you show up in the new search landscape.

Step 1: Define Your GEO Objective (Week 1)

Before you even talk to agencies, you need to know what you’re trying to achieve. How to choose a GEO agency starts with knowing what you actually need.

Are you trying to:

  • Get visible in AI responses for your core product/service category?

  • Establish thought leadership and executive visibility in AI answers?

  • Defend market position against competitors showing up more in AI systems?

  • Test GEO as a channel before committing a larger budget?

  • Move faster than your competitors in this space?

These are different objectives, and they matter. They’ll influence who you should hire and what success looks like.

Write down 2-3 specific things you want to achieve in the first 12 months. Be concrete. “Increase visibility in AI systems” is too vague. “Get mentioned in at least 20% of ChatGPT responses about [specific topic]” is better.

Step 2: Assess Your Internal Capacity (Week 1)

How much of this are you going to handle internally versus outsource?

Some companies have strong content teams but need strategy and optimization. Others need someone to handle everything. Understanding your internal capacity shapes what kind of agency makes sense.

Ask yourself:

  • Do we have content people who can execute on recommendations?

  • Do we have data/analytics capability to measure results?

  • Do we have marketing leadership bandwidth to be hands-on with the agency?

Your answers determine whether you need an agency that executes everything or one that’s more strategic/advisory.

Step 3: Create Your Initial Agency List (Week 2)

Don’t go to the first agency you find. Create a shortlist of 5-8 potential partners based on:

Recommendations from trusted sources (colleagues, other marketers you know). Agencies that show up in search results or conversations about GEO (they’re likely to be more current). Agencies that have published about GEO or demonstrated thought leadership. Agencies in your geographic region if that’s important to you (it often isn’t anymore, but sometimes it matters for timezone or in-person collaboration).

Don’t overthink this phase. You’re just creating a reasonable list to evaluate.

Step 4: Initial Screening Call (Week 2-3)

Get on a 20-30 minute call with each agency to assess fit without going deep.

The script is simple:

  • Explain your objectives from Step 1

  • Ask them to walk through their GEO approach at a high level

  • Ask about their experience in your industry

  • Ask what the engagement process would look like

  • Get a rough sense of pricing/structure

The goal isn’t to get a full proposal. It’s to screen out agencies that:

  • Don’t seem to understand what GEO actually is

  • Don’t have relevant experience

  • Have a communication style that doesn’t click with you

  • Are way out of budget

After these calls, you should be able to narrow down to 2-3 finalists.

Step 5: Deep Evaluation With Finalists (Week 3-4)

Now you’re serious about these agencies. With your finalists, you want:

A real case study conversation: Not a case study PDF they hand you. A conversation where someone walks you through a project, explains what they did, why, what worked, what didn’t, and what they learned. The honesty in this conversation matters.

Their answer to your specific situation: Ask them how they would approach your objectives. Not a full proposal yet, but how would they think about it? What questions would they ask? What would they want to learn?

Reference calls: Talk to at least one client they’ve done similar work for. Ask about the actual experience. Was the agency responsive? Did they deliver what they promised? Would they hire them again?

Their point of view on the future: Where do they think AI search is going? How are they positioning clients for that? Are they forward-thinking or reactive?

Step 6: Proposal and Comparison (Week 4)

Ask your top choices to submit proposals. The proposal should include:

  • Clear understanding of your objectives and their interpretation of them

  • Proposed approach and methodology (not generic; specific to your situation)

  • Specific deliverables (not vague like “strategic recommendations”)

  • Timeline and key milestones

  • How success will be measured

  • Pricing and what’s included

  • Who will be working on your account

  • How often you’ll communicate and what you’ll see

Now you can actually compare.

What you’re looking for:

  • Does the proposal show they understood your situation?

  • Is the methodology specific to your needs or generic?

  • Are the deliverables clear and measurable?

  • Does the timeline make sense?

  • Does the pricing align with what you’re willing to spend?

  • Do you trust the people who will be doing the work?

Step 7: The Gut Check (Week 5)

After all this, you should be down to 1-2 agencies. Now comes the gut check.

Set up a final conversation with the decision-maker at each agency (not the sales person, the person who would actually run your account). How do you feel about them? Do you trust them? Do they ask smart questions? Are you excited to work with them or just resigned?

You should feel genuinely good about this decision, not just “good enough.” Best GEO agencies for B2B / SaaS / eCommerce aren’t necessarily the ones with the biggest brand. They’re the ones where you feel like they genuinely get your business and are excited to help you solve your problem.

Step 8: Negotiate and Finalize (Week 5-6)

Once you’ve made your choice, don’t just accept their first proposal.

Discuss:

  • Can you start with a 3-month pilot before committing to 12 months? (Reasonable agencies will say yes.)

  • What’s the exit process if it’s not working after 90 days?

  • What flexibility do you have to adjust scope if you learn things along the way?

  • What happens if key people on the account leave?

  • How frequently can you adjust strategy based on learnings?

These conversations matter because they set expectations and give you options if things aren’t working.

The Timeline

The whole process should take 5-6 weeks. If you rush it, you’ll likely make a bad choice. If you take longer than that, you’re probably overthinking it.

What Success Looks Like

You’ll know you made the right choice if:

  • They’re asking good questions about your business, not just executing tasks

  • They’re communicating regularly with actual insights, not just metrics

  • They’re willing to adjust strategy when things aren’t working

  • You feel like they genuinely care about your success, not just the contract

  • After 90 days, you have initial learnings even if results aren’t massive yet

The One Thing to Remember

The best best GEO agencies for B2B / SaaS / eCommerce are the ones that align with how your business thinks and operates. An agency that’s technically excellent but culturally misaligned will drive you crazy. An agency that’s culturally great but technically mediocre will frustrate you differently.

What you’re really looking for is alignment on both dimensions. That’s the sweet spot.
