How to Choose an SEO Agency: 15 Questions to Ask

Choosing an SEO agency is hard for a structural reason: the buyer usually cannot evaluate the work until a year of budget has gone. Proposals look alike, case studies are unverifiable, and the vocabulary is designed to sound technical. So companies choose on price or on confidence, and both are poor predictors.

This guide replaces confidence with questions. Fifteen of them, grouped by what they test — strategy, method, proof, content and authority, and the commercial terms — with the answer a good agency gives and the answer that should end the meeting. It closes with a comparison of pricing models, a short decision process, and our own answers to every question, because a guide that hides how its author would score is not much of a guide.

Why this decision is hard

Most professional services can be judged on a sample: a lawyer’s draft, an architect’s previous building. Organic growth cannot. Its results arrive months after the work, they are entangled with everything else the business does, and the agency is usually the one reporting them. That asymmetry is why the market contains so many firms selling activity — rankings, links, articles per month — instead of outcomes.

The buyer’s best defence is a set of questions that force the agency to expose its reasoning rather than its portfolio. Reasoning can be evaluated in a meeting; results cannot. What follows is the set we would want to be asked.

Before you talk to anyone

Agencies are good at defining the brief for you, in their favour. Write your own first. Four lines are enough:

• The outcome, in the business’s own units: qualified leads, revenue from a market, sign-ups for a product, citations for a category of questions. Not ‘more traffic’.
• The budget, including your own people’s time and any engineering or content production the work will need. Agency fees are typically less than half of the true cost.
• The timeframe over which you will judge it. Organic compounds; a six-month judgement rewards short-term tactics.
• The capacity you can commit: who will make decisions, who will ship changes, who will write or approve content. An agency without a counterpart inside the company produces recommendations, not results.

The fifteen questions

Ask all fifteen, in order, of every agency you are considering. Take notes against the ‘good answer’ column, and stop the process for any agency that produces a red flag in the ‘proof’ or ‘commercial’ groups.

Strategy

Method

Proof

Content and authority

Commercial

Pricing models compared

The model matters less than the scope attached to it, but each model creates its own incentives. Know what you are buying.

Red flags that end the conversation

• Guaranteed rankings or positions. Nobody controls the results page. A guarantee is either a lie or a promise about a query nobody searches for.
• ‘Proprietary’ or ‘secret’ techniques. Search engines publish what they reward. Anything secret is either ordinary work with a brand name or a spam-policy violation waiting to be caught.
• Link packages, link networks or prices per link. Paid and exchanged links violate published spam policies and put the whole site at risk.
• Content by volume. ‘X articles per month’ without a demand map and an editorial standard produces pages that compete with each other and decay.
• Ownership of your accounts. If they need to host your analytics or own your Search Console property, they are building a switching cost, not a channel.
• No losses, no limits, no ‘it depends’. Certainty about a system nobody fully controls is a sign of inexperience or salesmanship.
• Rankings as the headline metric. A firm that leads its reporting with positions has not thought about what your board needs to see.

How Lucidens answers these questions

It would be odd to publish fifteen questions and not answer them. In brief:

• Strategy (1–3). We start every engagement by saying what we would not do, and we tell prospective clients in the first conversation when organic is not the right investment for them. Priorities come from the Method: clarify the outcome and the measurement, then structure, then compound, then prove.
• Method (4–6). The first ninety days are the Clarify and Structure stages: baseline, demand research, technical and architectural foundations, and a measurement plan agreed before publishing starts. The people you meet are the people who do the work, and we deliver into your engineers’ and editors’ systems.
• Proof (7–9). Our Work names the projects and describes what was done; where our research draws on our own projects, we say which and we state the limitations. Measurement is designed in stage one and reported in your units. References are available from projects old enough to be judged.
• Content and authority (10–12). Content carries a named author, a date and sources. We use AI tools for drafting and research; the facts, judgement and evidence are ours. We do not buy, exchange or rent links. Answer-engine visibility is a named service with a method you can read.
• Commercial (13–15). You own the accounts, data, content and code. We prefer a scoped first phase followed by a rolling agreement with notice and a documented handover, and the scope states what is included. A first conversation is forty-five minutes with a partner, at no charge.

Making the decision

1. 01

   Write the four-line brief

   Outcome, budget, timeframe, capacity. Share it with every agency you talk to so that proposals are comparable.

2. 02

   Ask all fifteen questions of every candidate

   Score each answer 0–2 against the ‘good answer’ column. Eliminate any agency with a red flag in the proof or commercial groups regardless of score.

3. 03

   Call one old reference per finalist

   Ask what went wrong and how the agency behaved when it did. Ask whether the reference could explain the results to their own board.

4. 04

   Buy a scoped first phase, not a year

   An audit and plan, a migration, or a measurement design. Judge the working relationship and the quality of the thinking before committing to a retainer.

5. 05

   Agree the measurement before signing

   Baseline, page groups, definitions, cadence and the decision each quarterly report will ask for. If the agency resists this, you have your answer.

The bottom line

• Write your own brief first: outcome, budget, timeframe, capacity.
• Evaluate reasoning, not portfolios — the fifteen questions expose how an agency thinks before you have paid for a year of it.
• A good agency names what it will not do, shows a failure, agrees the measurement up front and leaves you owning everything.
• Guarantees, secrets, link packages, content by volume and account ownership end the conversation.
• Prefer a scoped first phase over a long retainer, and call a reference old enough to have an opinion.

Frequently asked questions

How much does an SEO agency cost?

It ranges from a few thousand to well over fifty thousand a month depending on market, scope and seniority, which is why the question is less useful than ‘what does the scope include, and what is the total cost including our own time?’ Judge price against the outcome in your brief and the agency’s answers to the fifteen questions, not against other agencies’ prices.

Should we hire an agency or build an in-house team?

Both, usually in sequence. An agency is fastest for strategy, technical foundations, migrations and measurement design — work that needs experience across many sites. In-house people are better for sustained content, product knowledge and day-to-day ownership. The best arrangement is often a scoped agency engagement that leaves behind a system an internal team can run.

How long should we give an agency before judging results?

Judge the method within the first quarter — the baseline, the plan, the quality of the technical and structural work, and how they work with your team. Judge the commercial results over two to four quarters against the baseline agreed at the start. Judging outcomes at three months rewards short-term tactics; refusing to judge the method at three months wastes a year.

Is it a red flag if an agency says no to something we ask for?

It is usually a good sign. An agency that declines a tactic, a market or a content line — and explains why — is protecting your outcome rather than its invoice. Be more worried about the agency that agrees with everything.

What should be in the contract?

Scope and deliverables; who does the work; ownership of accounts, data, content and code; the measurement plan or a commitment to agree one before work starts; term, notice and handover; what is excluded and at what rates; and the spam-policy and link-acquisition standards the agency commits to. If it is not written down, it is not agreed.

How is Lucidens different from an SEO agency?

We describe ourselves as an organic-growth consultancy because the work covers search engines, answer engines and knowledge networks, and because it starts from the business outcome and the measurement rather than from a keyword list. In practice the questions above are the fairest test; our answers are in the section How Lucidens answers these questions.
