Choosing an SEO agency is hard for a structural reason: you are buying expertise you do not have, which means you cannot easily judge the product. The industry knows this, and its worst actors are built on it. But bad agencies are surprisingly easy to expose if you ask the right questions, and fair engagements have a recognizable shape. Here is how to run the selection, from someone on the selling side with an obvious bias we will flag as we go.
Before you talk to anyone
Do two things first. Read our SEO pricing guide so quotes have context, and run through the free audit checklist yourself, even superficially. Knowing roughly what is wrong with your site turns every sales conversation from a pitch you absorb into claims you can test.
Questions that expose weak agencies
"What exactly will you do in the first 90 days?"
Good answer: specific and sequenced. Audit, then technical fixes, then content targets, with the reasoning. Bad answer: vague process talk, "proprietary methods", or deliverables measured in reports rather than changes to your site. If they cannot say what they will do, they are hoping you will not ask what they did.
"Which rankings can you guarantee?"
This one is a trap, deliberately. The only correct answer is "none, nobody can". An agency that guarantees positions is either lying or planning tactics that trade your site's future for a fast screenshot. Guaranteed-ranking pitches end more small business SEO stories badly than any other single thing.
"Who does the actual work on my account?"
At many agencies, the impressive person in the sales call is the last senior person you will speak to; delivery goes to a rotating junior bench. Ask who writes, who fixes, who you email, and how many accounts that person carries. (Our bias, disclosed: this question is the whole reason boutiques like ours exist. It is still the right question.)
"What will you need from me?"
Real SEO needs your input: site access, industry knowledge, approvals. An agency that needs nothing from you is planning generic work. "Nothing, we handle everything" sounds convenient and predicts template output.
"How will you report, and against what?"
You want plain-language monthly reporting tied to agreed goals: what was done, what changed, what is next, and leading indicators while rankings build (impressions and positions, per our timeline guide). A wall of charts with no "here is what we did" is where accountability goes to die.
"Can I leave, and what happens to the work?"
Month-to-month or short commitments are fair; twelve-month lock-ins with exit penalties are a business model, not a service. Also confirm in writing that you own everything: content, access, accounts, and that they hand it over cleanly if you go.
Red flags that end the conversation
- Cold outreach claiming your site has urgent problems they happened to notice.
- Guaranteed rankings or "we know people at Google".
- Prices dramatically below market. Real work has a cost floor; see the pricing guide.
- Link-building offers measured in volume ("50 links a month"). That is a penalty subscription.
- They will not show you their own site's performance. Cobbler's children logic applies: it does not need to be spectacular, but it should not be embarrassing.
- Pressure to sign today for a discount.
What a fair engagement looks like
- Starts with an audit and a prioritized plan you could, in principle, take elsewhere.
- Clear scope: what is included monthly, what costs extra, named.
- Month-to-month after an initial ramp period, with honest talk about the ramp (real SEO needs a few months to show; a fair agency says so upfront rather than hiding behind a contract).
- You own everything, always.
- Reporting a non-specialist can read in five minutes.
Weighing a boutique against a big agency
Big agencies offer breadth and headcount; the trade is that small accounts get the junior bench and the template. Boutiques offer senior attention and speed; the trade is less capacity and fewer specialisms under one roof. For most small businesses the deciding question is simple: at this agency, how important is my account? Be the meaningful client somewhere, not the rounding error anywhere.
Running a fair trial
Once you have a shortlist of one or two, structure the first engagement so both sides can prove themselves without a leap of faith:
- Agree the 90-day deliverables in writing before signing: audit delivered, named technical fixes shipped, first content live, baseline report established. Concrete enough that "did it happen?" has a yes or no answer.
- Agree the leading indicators you will judge months two through four on: impressions trend, positions on named terms, pages indexed. Rankings and revenue are the goal; these are the early evidence the goal is approaching. Judging month two by revenue guarantees mutual frustration.
- Set a check-in at month three with a real decision attached: continue, adjust scope, or part cleanly. A fair agency welcomes this because it also protects them from clients who expected magic.
- Get access squared away on day one. Analytics, Search Console, the website, the Business Profile. Trials die in week three waiting for a login more often than anyone admits.
The pattern to notice: everything above is just making the work inspectable. Good agencies operate this way by default; the ones that resist inspection are telling you something useful before you have paid for the lesson.
A low-risk way to test any agency, including us
Ask for a sample of their actual thinking about your site before you pay. An agency confident in its work can show it. That is precisely what our free audit is: a real audit of your site, by a person, with the findings ranked, whether or not you hire us. Compare it against whatever the other agencies on your list send. Judging the work beats judging the pitch, every time.
