15 Questions to Ask an SEO Agency (+ Red Flags)

How to Use This List in One Call

One disclosure before the list, because you deserve to know who is handing it to you: we build SEO software that competes with agencies for the same budget. The list below is still fair, and deliberately so. A good agency passes every question here without flinching, and a bad one fails it whoever wrote the questions. If an agency clears all fifteen, hire them with our blessing.

The 15 Questions, With the Answers Good Agencies Give

1. What exactly will you ship in the first 90 days? A good answer names deliverables: pages built, pages refreshed, fixes deployed. "Audits and optimization" is a schedule of activity, not a list of output, and it is how retainers evaporate.
2. Who does the actual work on my account?You want names and roles, and ideally the people themselves on the call. "Our team" usually means the salesperson leaves after signing and a rotating junior inherits you.
3. Which of your current clients can I speak to? At least one should be in a niche comparable to yours. An agency with happy clients offers references readily; an agency that hedges here is telling you something.
4. How will you measure success, and can I see a sample report? Good reports show clicks, enquiries, and the work shipped that month, in line with how SEO ROI is actually measured. Rank screenshots alone measure nothing a bank accepts.
5. What happens to the work if we part ways? The only good answer: you keep everything, and it lives in your accounts from day one. Content, analytics, and profiles held hostage are a business model, not an accident.
6. Do you build links, and how?Transparent methods you could read aloud to Google are fine. Paid placements are a walk-away; link schemes are named violations in Google's spam policies, and the penalty lands on your site, not theirs.
7. What would you fix on my site first, from what you can see today? A real observation about your actual pages proves they looked before the call. A generic answer means the pitch deck is the same for every prospect.
8. How do you decide what content to create? The good answer starts from query evidence, the kind you can gather from free sources, not from a content calendar invented in a brainstorm. Ask to see the evidence behind one past topic choice.
9. Who owns the content and accounts you create? You, always, in writing. Any arrangement where cancelling the retainer deletes the blog is a lease dressed up as an asset.
10. What do you need from me monthly?Honest agencies need your expertise: review time, customer questions, subject-matter facts. "Nothing, we handle everything" is a red flag, because content written without your knowledge reads like it.
11. How do you handle AI content? The credible answer is a process: where AI drafts, where humans review, and what the gate checks before publishing. Google penalizes scaled content without value, whoever wrote it, so "we never use AI" and "AI does everything" are both worse answers than a review process.
12. What results should I not expect in six months? Honest agencies name limits without prompting, because realistic SEO timelines are public knowledge. An agency that promises everything by month six has priced in your disappointment.
13. Why might we fail? A real answer shows they have failed before and know why: wrong market fit, thin budgets, unresponsive clients. An agency that has never failed has never been measured.
14. What is in the contract about early exit? Month-to-month after a short minimum beats an annual lock-in every time. Confidence in the work shows up as easy exits; twelve-month commitments show up where the work cannot hold clients on its own.
15. If my budget were half, what would you cut? This one reveals what they privately consider filler. If half the retainer can vanish without touching results, ask why it was in the proposal at full price.

The Red Flags That End the Conversation

• Guaranteed rankings or guaranteed timelines. Google itself says no one can guarantee a ranking, so the guarantee measures the agency's honesty, not its skill.
• Secret or proprietary link networks. "We cannot reveal our sources" means the sources would not survive being revealed.
• Rank-report-only measurement with no enquiry tracking. If nobody counts leads, nobody is accountable for them.
• Refusal to name who does the work or to show real client outcomes. Anonymity in a service business is a choice.
• Pressure to sign an annual contract today. Urgency is a discount on your diligence, and they know it.
• Badmouthing every previous agency the client had. If everyone before them was incompetent, the common denominator is them.

A single red flag is a question mark; two is a pattern; three is your answer.

Agency, Freelancer, Software, or DIY: The Honest Fit Table

These paths also carry very different price tags, and the fit decision is only half the math. Rather than repeat the numbers here, the full market-rate breakdown for retainers, hourly consultants, projects, and software lives in the small-business SEO cost guide, which is worth reading before any agency quotes a figure at you.
