To choose an SEO agency, ignore the portfolio slides and ask twelve questions in the sales call: about expected timelines, guarantees, how links get built, what happens to your site if you leave, and how they measure success. A good agency answers all twelve plainly, because honest answers are their competitive advantage. A bad one hedges, guarantees, or dazzles. Yes, we are an agency writing this, which means you should apply every question below to us too; that is rather the point.
Why vetting is genuinely hard
SEO has a built-in accountability problem: results take months, causes are tangled, and by the time a business learns it bought nothing, the retainer is a year old. The industry attracts both excellent operators and confident frauds, and their websites look the same. What separates them is not the pitch but the answers to specific questions, because the frauds have rehearsed the pitch and not the follow-ups.
The 12 questions, and what the answers mean
1. "How long until we see results?"
Good answer: a range with reasons, usually three to six months for movement and six to twelve for clear ROI, depending on your starting point. Walk away: anything under a month, or a guarantee. Our own honest timelines are the benchmark to compare against.
2. "Can you guarantee first-page rankings?"
Good answer: no, and here is why nobody can. Walk away: yes. Google itself warns that nobody can guarantee rankings, so a guarantee tells you the agency is lying to you before the contract is even signed.
3. "How exactly do you build links?"
Good answer: named methods: digital PR, original data, guest contributions, partnerships, with examples of real placements. Walk away: vagueness, "our private network", or a fixed number of links per month at a suspiciously smooth price, which nearly always means link farms that risk penalties you will pay for long after they are gone.
4. "What did you do for a client in a situation like ours?"
Good answer: a specific story with the starting point, the work, the timeline, and numbers, including something that did not work. Walk away: only aggregate percentages with no context, or case studies they cannot discuss in detail.
5. "Who actually does the work on our account?"
Good answer: named people and their roles, and honesty about anything outsourced. Walk away: a senior partner sells you, then the account vanishes into an unnamed delivery team. You are hiring the people, not the logo.
6. "What do you need from us to succeed?"
Good answer: a real list: site access, content approvals, subject expertise, technical implementation. SEO is a collaboration, and good agencies say so. Walk away: "nothing, we handle everything." That means either thin generic content or work so superficial it needs nothing from you.
7. "What happens if we cancel?"
Good answer: you keep everything: content, accounts, analytics, and access, with a clean handover. Walk away: agencies that own "their" content, hold your accounts, or bury cancellation in twelve-month lock-ins. Hostage-taking disguised as terms is the tell of a business that keeps clients by force rather than results.
8. "How will you report, and what is in the report?"
Good answer: a monthly report tying work done to outcomes: rankings, traffic, leads, and what changed and why, plus what is planned next. Walk away: screenshots of vanity dashboards, or reports of "activities" (blogs posted, links acquired) with no line to business results.
9. "Which metrics do you consider success?"
Good answer: qualified traffic, leads, and revenue influence, with rankings as a means. Walk away: success defined as rankings for keywords nobody searches, the oldest trick in the reporting book.
10. "How are you adapting to AI search?"
Good answer: a concrete method: structured data, answer-shaped content, entity work, and tracking citations across assistants, not just a buzzword. This question now separates agencies maintaining their craft from agencies coasting. Our SEO vs AEO comparison shows what a real answer contains. Walk away: "AI does not change anything" or, equally, mystical AI promises with no method.
11. "Will you tell us if something is not working?"
Good answer: yes, with an example of a time they changed course and told the client why. Walk away: agencies that have never had anything fail. In a field with this much uncertainty, a perfect record is a record of hidden failures.
12. "Why should we not hire you?"
Good answer: real fit boundaries: industries they do not know, budgets too small to move anything, timelines they cannot honor. An agency that can name a bad-fit client has standards. Walk away: "no reason at all." Everyone is not their ideal client, and they just told you they will say anything.
The pricing reality nobody publishes
Real SEO is labor: strategy, content, technical work, and outreach performed by skilled people, and its floor price reflects salaries, not software. Suspiciously cheap retainers reliably mean automated reports, spun content, and link networks, which cost more to clean up than they ever cost to buy. At the other end, expensive does not guarantee good either; the questions above matter at every price. The honest rule: if the retainer could not plausibly pay for the hours of skilled work being promised, it does not.
Frequently asked questions
Should I hire a local agency or does location not matter?
For most SEO work, capability beats geography, and remote collaboration is standard. Local knowledge earns its premium mainly in local SEO, where an agency that understands your market's geography and customer behavior reads the map pack better.
Agency, freelancer, or in-house?
Budget and scope decide. A strong freelancer suits focused problems; in-house suits companies where search is the core channel and can fill a full role; agencies suit businesses that need the full stack, content, technical, links, and AI visibility, without hiring four people.
What is a reasonable contract length?
Quarterly commitments with a fair notice period are reasonable, because SEO genuinely needs months. Twelve-month locks with penalty exits protect the agency from its own results; ask why they need that protection.
How many agencies should I talk to?
Three is usually enough to calibrate. Ask all three the same twelve questions and the differences will be louder than any pitch deck.
The bottom line
The best agencies are easy to interrogate, because honest answers are their sales pitch, and the worst are easy to catch, because the truth is the one thing they have not rehearsed. Print the twelve questions, ask every candidate the same set, and choose the one whose answers you could repeat to your accountant with a straight face. And since fairness cuts both ways: ask us all twelve. The free SEO and AEO audit is how we answer the first four before you have spent anything at all.
