Most businesses don’t realize they’ve hired the wrong SEO agency until months of budget are gone and nothing has moved. Rankings are flat. Traffic is stagnant. The monthly report is full of charts that don’t connect to revenue.

SEO is a long-term investment, and switching agencies mid-stream costs time, money, and momentum. That’s why the evaluation process matters so much before you sign anything.

This guide gives you a practical framework for how to choose an SEO agency with confidence, covering what to look for, the right questions to ask, and the red flags that should stop you cold.

What to Look for in an SEO Agency

Not every agency that calls itself an SEO firm is actually equipped to move the needle for your business. Here’s what to look for in an SEO agency during your evaluation:

• Verifiable results, not just logo walls. Any agency can display brand logos on a website. Ask for specific results, the strategy behind them, and a timeline. If they can’t walk you through a real example, that’s a problem.
• Transparency in process and reporting. You should always know what’s being done, why it’s being done, and how it’s performing. Vague monthly reports are a warning sign.
• A fit for your business type. B2B SEO, B2C SEO, local SEO, and national SEO are different disciplines. Make sure the agency has experience with businesses that look like yours.
• Current expertise, not just traditional SEO. Search has changed. The agency you hire should have a clear strategy for both traditional rankings and visibility in AI-generated search results.
• A real team behind the pitch. Know who will actually work on your account. A polished sales team backed by junior offshore contractors isn’t the partnership you’re paying for.

A strong agency can speak to results they’ve driven in your industry. If they can’t point to anything relevant, that’s worth noting.

Does the Agency Understand AI Search?

Google isn’t the only place people find businesses anymore. ChatGPT, Perplexity, Gemini, and Google’s AI Overviews are reshaping the way buyers access information. When someone asks an AI tool about the best vendor in your category, your brand either shows up in that answer or it doesn’t.

An agency that only optimizes for traditional search results is already working with an incomplete picture. Generative Engine Optimization (GEO) is the practice of ensuring your brand is cited and referenced in AI-generated answers, not just ranked on a list of blue links.

When evaluating an agency, ask:

• Do they understand the difference between traditional SEO and AI Optimization?
• Can they explain how AI models decide which sources to cite?
• Do they have a strategy for earning brand mentions in AI-generated results?
• How are they measuring your AI search footprint alongside traditional rankings?

At Globe Runner, we built BrandVisibility.ai specifically to answer that last question. It’s a proprietary tool that measures how and where your brand appears in AI-generated search results, giving you real data instead of guesswork. Most agencies are still treating AI search as a future problem. We’re tracking it for our clients right now.

Traditional SEO tells you where you rank on Google. AI Optimization tells you whether your brand appears when AI tools answer the questions your customers ask.

What to Ask During the Evaluation Process

Use these questions to ask an SEO agency as a filter — the right partner will welcome every one of them. A weak one will dodge them or give you rehearsed non-answers.

1. How do you approach keyword research, and what tools do you use?
2. Who will be working on my account day-to-day?
3. How do you report progress, and how often? Ask to see a sample report.
4. What KPIs do you track beyond rankings? Traffic, conversions, and revenue impact should be part of the conversation.
5. How do you stay current with algorithm updates and AI search changes?
6. Can you show results you’ve achieved for a business like mine?
7. What does success look like at 3 months, 6 months, and 12 months?
8. Do you offer AI Optimization, and how do you measure it?
9. What tools do you use to track visibility in AI-generated search results?

Pay attention to how they respond, not just what they say. Confident, specific answers signal experience. Vague language or deflection signals you may be getting sold a service they don’t fully understand.

SEO Agency Red Flags to Watch Out For

Knowing what to look for in an SEO agency also means knowing what to walk away from. These are the biggest SEO agency red flags:

• Guaranteed #1 rankings. No one can promise a specific ranking. Google doesn’t work that way, and any agency claiming otherwise is misleading you.
• Vague deliverables. “We’ll improve your SEO” is not a strategy. You should receive a clear scope of work with defined activities and timelines.
• No access to your own data. You should always own and have direct access to your Google Analytics, Google Search Console, and any reporting dashboards. An agency that controls your data controls your leverage.
• Tactics they won’t explain. Good SEO is not a black box. If an agency won’t walk you through their methodology, assume the reason isn’t flattering.
• Lock-in contracts with no performance accountability. Long contracts aren’t inherently bad, but there should be defined benchmarks and a clear path to exit if performance falls short.
• Pricing that seems too good. Unusually low rates often signal low-quality link schemes, outdated tactics, or work being outsourced to vendors who don’t understand your market.
• No mention of AI search. If you go through an entire pitch and the agency never brings up AI Overviews, GEO, or how they’re thinking about generative search, they’re behind. This isn’t a future consideration anymore.

What the Hiring Process Should Actually Look Like

A strong agency doesn’t just send you a proposal and wait. Here’s what a well-run process looks like when hiring an SEO company:

• Discovery call before the proposal. The agency should want to understand your business, goals, competitive landscape, and current performance before recommending anything.
• A site audit before you sign. Any credible agency should be willing to do at least a high-level audit of your current site. This shows they’ve done their homework and helps set realistic expectations.
• Strategic thinking, not just a task list. You want to see that they understand the “why” behind their recommendations, not just a checklist of deliverables.
• They bring up AI search without being prompted. A forward-thinking agency raises the topic on its own. If you have to ask about it, they’re probably playing catch-up.

The sales process is a preview of the working relationship. If communication is slow, vague, or hard to follow before the contract is signed, it won’t improve after.

Why the Right Agency Pays for Itself

A bad SEO hire doesn’t just waste money. It can take months to reverse the damage from poor practices, and the opportunity cost of flat organic growth compounds over time.

The right partner builds visibility that grows on its own. Organic traffic isn’t a one-time campaign. Done well, it becomes a compounding asset. A well-optimized page can generate leads for years without ongoing paid spend.

With AI search now influencing buying decisions before a user ever clicks a link, AI Optimization is part of that asset. Brands that appear in AI-generated answers are reaching buyers earlier in the research process, before they’ve started comparing options.

Globe Runner’s approach combines traditional SEO fundamentals with AI Optimization and BrandVisibility.ai-powered measurement. You get a clear picture of where you stand, what’s being done, and what it’s producing.
