If you’re wondering how to brief an SEO agency, the answer is refreshingly simple: write a one-page document before the first call that covers what you sell, who buys from you, what success looks like, and what’s wrong with your website today. That single page gets you comparable quotes, faster audits, and far fewer surprises — and it takes about an hour to write.
Most businesses do this backwards. For example, they ring three agencies, sit through three slick pitches, and pick the one with the best slides. As a result, six months later they wonder why the “strategy” looks nothing like their business. The problem wasn’t the agency — nobody told the agency what they were trying to do. A proper brief forces the agency to respond to your reality instead of selling you their standard package.
Why Your Brief Matters More Than Their Pitch
Think of the brief as the job description and the agency’s proposal as the job application. Without a clear job description, you can’t compare applications — and every candidate will claim to be perfect. When five agencies receive the same brief, their replies become comparable: you can see who addressed your situation and who pasted a generic template.
Therefore, writing the brief also makes you smarter before you spend a penny. Owners who’ve written down their goals, numbers, and constraints spot red flags faster — the same clarity that protects you when choosing an SEO agency.
A Brief Is Not a Proposal — Don’t Mix Them Up
Your brief is what you give the agency: your business, your website, your goals, your budget range, your access. Their proposal is what they give back: their audit findings, their plan, their price, their timeline. Skip your side and the agency has to guess — and agencies that guess write proposals full of assumptions that rarely match your reality.
And keep it short. Anything over two pages won’t get read. One page is the sweet spot: every agency reads it, and the good ones tailor their answer to it.
How to Brief SEO Agency: The 8-Question Template
Copy the template below into a document and answer each question in a few honest sentences. If a line genuinely doesn’t apply, write “not needed” rather than deleting it — that tells the agency you thought about it.
- 1. What do we sell, and to whom? Your services, your typical customer, and where they’re based. “We install heat pumps for homeowners across the South East” beats “we do heating.”
- 2. What does our website look like today? The URL, roughly how old it is, the platform it runs on, and anything you already know is broken or slow.
- 3. What does success look like? The one or two outcomes that matter: more quote requests, more bookings, more calls. Not “more traffic” — traffic is not a business goal.
- 4. How do we measure those outcomes today? Contact form, phone calls, booking system, nothing yet — be honest. The agency needs to know whether measurement starts from zero.
- 5. What have we tried before? Previous SEO work, ad spend, a freelancer, nothing at all. Bad past experiences are genuinely useful information.
- 6. Who are we up against? Two or three competitors who rank above you. This one sentence saves the agency hours of guesswork.
- 7. What’s the budget range and timeline? A range is fine — even “£500–£800 a month” transforms proposals, because the agency stops pitching what you can’t afford.
- 8. Who owns what? Domain, hosting, analytics, Search Console, Business Profile — and who signs off on decisions. Sorting this out in the contract starts in the brief.
End the brief with one instruction: “Please address each section in your proposal.” That single line is what makes five replies comparable.
Weak Answers vs Strong Answers
The gap between a vague line and a useful one is everything. Take the goals section.
Weak: “We want to rank higher and get more traffic.”
Strong: “We want more boiler-service enquiries from homeowners in Surrey. We currently get about 6 enquiries a month through our contact form and don’t track phone calls. We’ll review progress quarterly against enquiries, plus clicks for our service pages in Search Console.”
The strong version names the pages that matter, says how success gets counted, and tells the agency how often you’ll look. It also makes it much harder for anyone to report success using numbers you don’t care about. Run this test on every section: could a stranger act on this sentence without asking you another question? If not, rewrite it.
5 Briefing Mistakes That Cost Businesses Money
1. Hiding your budget. Treating your budget like a state secret produces fantasy proposals — a £300/month budget quoted against a £3,000/month plan. A range keeps everyone honest.
2. Leading with traffic goals. “Double our traffic” sounds decisive, but traffic from people who’ll never buy is worth nothing. Measure enquiries and bookings instead — the same principle behind good monthly SEO reporting.
3. Skipping the “what we tried” section. If a previous agency burned you, say so. What went wrong — vague reports, surprise costs, no communication — is the best instruction you can give the next one.
4. Letting the salesperson write your brief. A brief written by the seller shapes the buying criteria in the seller’s favour. Write yours first, then let them respond to it.
5. Freezing the brief after month one. Your first brief is a hypothesis. Revisit it after a month: mark what was wrong, add what you learned. And if you spot signs your agency is wasting your money, the original brief is your evidence of promised versus delivered.
What to Do After You Send the Brief
Send the brief before the first call — not during, not after. Then use the call as a test: does the agency refer to your specifics, or retreat into generalities? Ask them to point at the section of your brief that shaped each recommendation. A good agency says, “Because your enquiries come through the form, we’d prioritise the service pages over the blog.” A weak agency talks about SEO in the abstract, as if your business didn’t exist.
Keep the brief alive during the engagement too. Confirm the basics — the audit, the first month’s work, the realistic SEO timeline — against the goals you wrote down before anyone was paid. Google’s own search documentation is a useful companion while you write it: you don’t need to become an SEO expert to brief one, you just need to know your own business, written down.
One page is the sweet spot for an SEO agency brief. Short enough that every agency actually reads it, long enough for a good agency to tailor its proposal to your business. Past two pages, trim it — nobody reads a brief that reads like a report.
Include the site’s URL, approximate age, platform (WordPress, Shopify, etc.), and anything you already know is broken — slow pages, traffic drops, previous penalties, or a recent migration. Honest context about the current state helps the agency scope the technical work and price the first month’s audit fairly.
Yes — always give a budget range in your brief, such as £500–£800 a month. Hiding the budget produces fantasy proposals built around prices you can’t afford. A range doesn’t lock you into paying the top number; it simply keeps agencies pitching plans in your financial reality.
State one or two measurable outcomes, how you count them today, and how often you’ll review progress. For example: “We want more service-page enquiries; we currently track 6 a month via our contact form; we’ll review quarterly.” Measurable goals stop agencies reporting success with vanity metrics.
Yes. Calls are for discussion; the written brief is the record both sides work from. Anything agreed verbally drifts over time, while a written brief anchors the proposal, the contract, and later conversations about whether the agency is delivering what was promised.
The bottom line: an hour of honest writing before you talk to any agency is the highest-return SEO investment you’ll ever make. The brief turns five different sales pitches into five answers to the same questions — and from there, the right choice usually makes itself.
