The quality of work you get from an SEO agency depends heavily on what you give them to work with. A sharp, well-prepared brief doesn’t just save time during onboarding. It shapes the strategy, sets realistic expectations on both sides, and gives the agency enough context to start doing useful work from week one instead of spending the first month asking questions you could have answered upfront.
That might sound obvious, but most businesses walk into their first agency call with little more than “we want to rank higher.” And that’s fine as a starting point, but it’s not a brief. This guide covers exactly what to prepare before that first conversation, so the agency can hit the ground running and you can evaluate whether they’re the right fit based on how they respond to real information, not just a sales pitch.
Why Your Brief Shapes the Work You Get Back
Think of your agency brief as the foundation for everything that follows. A vague brief gets you a vague strategy. A detailed one gets you a digital strategy built around your actual business, your actual competitors, and your actual goals.
Agencies aren’t mind readers. When they don’t have enough information, they fill in the gaps with assumptions. Sometimes those assumptions are reasonable. Often they’re not, because they’re based on what’s typical for your industry rather than what’s true for your business. The result is a scope of work that looks professional but doesn’t quite fit, and then both sides spend weeks course-correcting.
A good brief also helps you filter agencies. If you hand over a detailed brief and the agency comes back with a generic proposal that doesn’t reference any of it, that tells you something. The brief is a test as much as it is a resource.
Business Information Worth Preparing
Start with the basics. This is the stuff that feels obvious but regularly gets missed or communicated in fragments across multiple emails.
Company Overview
Write a short paragraph covering what your company does, how long you’ve been trading, and where you operate. Include the structure of your products or services and which ones matter most commercially. If you’re a multi-location business, clarify which locations are priorities. If you sell nationally but your leads come from three specific regions, say that.
Products, Services, and USPs
List your core offerings and, for each one, note what makes your version different from competitors. Not marketing slogans. Actual differences. Do you have faster turnaround? A proprietary process? Certifications that competitors lack? Lower minimums? These USPs give the agency material to work with when building landing pages, writing content, and identifying search terms worth targeting.
If you’re not sure what your USPs are, that’s useful information too. It tells the agency they may need to help you define positioning before jumping into keyword research.
Target Markets
Be specific about who you sell to. B2B or B2C? Which industries? Which company sizes? Geographic focus? The more precise you are here, the better the agency can align keyword targeting, content strategy, and technical priorities to the people who actually buy from you.
How to Frame Your SEO Goals
“We want to rank number one for [keyword]” is the most common goal agencies hear, and it’s almost always the wrong framing. Not because ranking doesn’t matter, but because a single keyword ranking tells you very little about business impact.
Better goals look like this:
Traffic goals: “We want to increase organic traffic to our service pages by 40% over 12 months”
Conversion goals: “We want organic search to generate 20 qualified leads per month”
Visibility goals: “We want to appear in the top three results for our core service terms in our target cities”
Revenue goals: “We want organic to account for 30% of total revenue by Q4”
The specific numbers matter less than the framing. When you tie SEO goals to business outcomes, the agency can build a strategy that optimises for those outcomes rather than chasing vanity metrics. They can also tell you honestly whether your goals are realistic given your budget, timeline, and the competition you’re up against.
If you don’t have specific KPIs in mind, say that. A good agency will help you set them. But come prepared with at least a sense of what success looks like for your business, even if it’s rough.
Defining Your Target Audience and Buyer Personas
Your agency needs to understand who you’re trying to reach, not just in demographic terms but in terms of how those people search and what they care about when they find you.
A buyer persona for SEO purposes should cover:
Who they are: Job title, seniority, industry (for B2B). Age range, location, life stage (for B2C).
What triggers their search: What problem or need sends them to Google? Are they researching, comparing, or ready to buy?
What they care about: Price? Speed? Quality? Trust? Expertise? Different audiences weight these differently, and that affects everything from keyword selection to page structure.
How they describe the problem: The language your customers use is often different from the language you use internally. If your customers search for “damp proofing” but you call it “moisture management services,” the agency needs to know that.
You don’t need formal persona documents. Bullet points work. The goal is to give the agency enough to target the right people with the right content at the right stage.
Competitive Context: Search Competitors vs Business Competitors
This one catches people out. Your business competitors and your search competitors are often different companies.
You might compete with three other firms for contracts, but in Google’s results, you’re up against directories, comparison sites, industry publications, and businesses from adjacent sectors. A plumbing company competing for “emergency plumber London” isn’t just up against other plumbers. They’re competing with Checkatrade, Bark, Yell, and a dozen aggregator sites.
Prepare two lists:
Business competitors: The companies you lose deals to. Who are they, and what do they do better (or differently)?
Search competitors: The websites that currently rank for the terms you want to rank for. If you’ve done any keyword research or even just Googled your main services, note who keeps appearing.
If you haven’t identified your search competitors, don’t worry. That’s part of what competitor audits are for. But if you already have a sense of who’s dominating the results, sharing that saves the agency time during their initial competitor analysis.
Budget and Timeline Expectations
Budget conversations are awkward. Most businesses don’t want to name a number first, and most agencies don’t want to quote without understanding the scope. But avoiding the topic entirely wastes everyone’s time.
You don’t need to commit to an exact figure before the first call. But you should have a realistic range in mind. If your budget is between two and four thousand pounds per month, say that. It lets the agency tailor their proposal to what’s actually achievable within your investment level, rather than pitching a strategy you can’t afford or underselling what they could do for you.
A few things worth knowing about SEO budgets:
SEO is ongoing, not a one-off project. Monthly retainers are standard because the work (content, technical fixes, link building, reporting) is continuous.
Results compound over time. Month one won’t look like month six. If you need immediate results, PPC might need to run alongside SEO while organic builds.
Cheaper isn’t always cheaper. An agency charging half the rate but delivering generic work that doesn’t move the needle costs more in the long run than one that charges fairly and gets results.
On timelines, be upfront about any deadlines or seasonal peaks. If you’re launching a new product in September and need content live by August, the agency needs to know that during onboarding, not in July.
Historical SEO Context
If you’ve worked with an SEO agency before, or had someone in-house handling SEO, the new agency needs to know what happened. Not to judge the previous work, but to avoid repeating mistakes and to understand the current state of your site.
Things to share:
Previous agencies or consultants: Who were they, how long did the engagement last, and why did it end?
What was done: Link building? Content? Technical audits? Site migrations? Knowing what’s already been tried helps the new agency prioritise.
Known issues: Have you ever received a manual action or penalty from Google? Been hit by a core algorithm update? Had a site migration that went badly? These aren’t embarrassing admissions. They’re critical context.
Current performance: Even a rough sense of your organic traffic trend is useful. Is it growing, flat, or declining? Has anything changed recently?
If you have access to historical data in Google Analytics or Google Search Console, mention that. The agency will want to review it, and knowing it exists upfront speeds things along.
Access and Assets to Provide
An agency can’t do much without access to your platforms. Prepare a list of what you can provide, and start the internal process of granting access before the engagement formally begins. Waiting for IT to set up accounts is one of the most common delays in new SEO engagements.
Platform Access
Google Search Console: The single most important tool for SEO. If you don’t have it set up, the agency will need to do that first. If you do, grant them user-level access. Our Google Search Console guide covers the basics if you’re unfamiliar.
Google Analytics (or whatever analytics and tracking platform you use): The agency needs to see traffic data, conversion data, and user behaviour. GA4 is standard, but if you’re using something else, let them know.
CMS access: Whether it’s WordPress, Shopify, or a custom build, the agency will need some level of access to make technical changes, publish content, and implement recommendations.
Google Business Profile: If you’re a local business, this matters. The agency may need to optimise your listing, manage reviews, or update information.
Brand Assets
Share your brand guidelines if you have them. Logo files, colour codes, tone of voice documents, approved messaging. If you don’t have formal guidelines, that’s fine, but tell the agency what you do and don’t want in terms of how your brand is represented.
If you have existing content, share examples of pieces you think represent your brand well, and any that don’t. This gives writers and strategists a concrete reference point rather than guessing at your preferences.
Communication Preferences and Reporting
This is where a lot of agency relationships quietly go wrong. Mismatched expectations around communication cause more frustration than actual performance issues.
Before the first call, think about:
Reporting frequency: Monthly is standard for SEO reporting. Some businesses want fortnightly check-ins. Others are happy with a monthly report and a quarterly strategy review. Know what you need.
Reporting format: Do you want a dashboard you can check anytime? A PDF report? A live call walking through the numbers? Different agencies handle this differently, and your preference matters.
Contact points: Who on your side is the day-to-day contact? Who has final sign-off on content and strategy? If these are different people, the agency needs to know.
Response expectations: How quickly do you expect replies? Are you comfortable with email, or do you prefer Slack or Teams? Setting this upfront prevents the slow-burn resentment of “they never get back to me.”
Be honest about how involved you want to be. Some clients want to approve every piece of content. Others want to hand over the keys and check in monthly. Both are valid, but the agency needs to plan their workflow around your level of involvement.
The Difference Between an SEO Brief and a Content Brief
Worth clarifying, because they’re different things that sometimes get conflated.
An SEO brief is what this article is about. It’s the information you provide to an agency at the start of an engagement so they can build and execute a strategy. It covers your business, goals, competitors, budget, and access requirements.
A content brief is something the agency produces for individual pieces of content. It specifies the target keyword, search intent, word count, heading structure, internal links, and competitor pages to beat. Content briefs are a downstream output of the SEO strategy, not something you need to prepare yourself.
If an agency asks you to write your own content briefs, that’s a yellow flag. You’re paying them for strategic expertise. You should provide the business context. They should translate that into actionable content plans.
What Agencies Actually Do With Your Brief
A well-prepared brief doesn’t just sit in a folder. It feeds directly into the first phase of work.
Your business overview and USPs inform the messaging strategy and help the agency identify which keywords are commercially relevant, not just high-volume. Your target audience shapes the content approach and the language used. Your competitor lists give the agency a starting point for their own competitor analysis, which will go deeper than what you’ve provided but benefits from your commercial perspective.
Budget and timeline set the pace. A limited budget means prioritisation. The agency will focus on the highest-impact work first and build from there. Your historical context helps them avoid wasting time on audits that duplicate work already done or strategies already proven ineffective for your site.
Access to your platforms lets the agency run a proper technical audit, benchmark your current performance, and start identifying opportunities from day one rather than week three.
How Your Brief Should Evolve Over Time
The brief you prepare for your first call isn’t a static document. As the engagement matures, your brief to the agency should evolve too.
In the first three months, the agency is learning your business. They need detailed context and regular input. By month six, they should understand your market well enough that your input shifts from “here’s our business” to “here’s what’s changed.” New products, new competitors, shifting priorities, seasonal patterns you’ve noticed.
Quarterly strategy reviews are a good time to update the brief. Not rewriting it from scratch, but flagging new information: a competitor launched a new site, your best-selling product changed, you’re expanding into a new region, or a Google update hit your traffic. These updates keep the strategy aligned with reality rather than running on stale assumptions.
The best agency relationships are the ones where both sides keep communicating openly. Your brief starts the conversation. It shouldn’t end it.
Making Your First Call Count
Walk into that first agency call with your brief prepared and you’ll get something most businesses don’t: a productive conversation from the start. Instead of spending 45 minutes on background questions, you can spend it discussing strategy, asking the agency how they’d approach your specific challenges, and evaluating whether their thinking aligns with your goals.
If you’re still choosing between agencies, the brief also gives you a consistent basis for comparison. Hand the same brief to three agencies and compare what comes back. The quality of their response to your brief tells you far more than their sales deck ever will.
Preparation isn’t glamorous, but it’s the difference between an SEO engagement that delivers and one that stalls before it starts. Get the brief right and you give the agency, and yourself, the best possible chance of making it work.
