What to Tell Your Marketing Agency Before Starting

What should I tell a marketing agency before starting: goals, KPIs, and what success means

The difference between marketing goals and business goals

Agencies frequently hear “increase awareness” and “get more leads” in kickoff calls. Neither phrase gives an agency anything useful to work with. What agencies need are specific business goals tied to real numbers: grow revenue by 30% in Q3, reduce cost-per-acquisition below $80, or hit 200 qualified leads per month via paid search. The distinction between a business goal and a marketing goal matters because it determines how the agency scopes the work and which channels they prioritize.

A business goal defines the outcome your company needs. A marketing goal defines the specific, measurable activity that drives that outcome. Bring both to the first meeting, even if the numbers are rough.

Standard KPIs by channel and how to set them before kickoff

You don’t need to be a data analyst to arrive with a basic KPI framework. For SEO, the core metrics are organic traffic, keyword rankings, and conversions from organic search. For paid ads, focus on ROAS, cost-per-acquisition or cost-per-lead, CTR, and conversion rate. For content, engaged sessions, assisted conversions, and pipeline contribution are the metrics that connect content activity to business outcomes.

Clients who arrive with even a rough KPI framework give their agency a measurable north star from day one. Pair those KPIs with a reporting cadence expectation: weekly health checks for campaign pacing and technical issues, monthly performance reviews for trend analysis, and quarterly strategic reviews for big-picture budget and direction decisions.

Your target audience and the competitive landscape your agency needs to see

Audience details that actually help an agency plan

Generic persona cards don’t help an agency build campaigns. What agencies need is real-world audience intelligence: where your customers spend time online, what content formats they engage with, which objections they raise in the sales process, and what messaging has resonated historically. The most useful audience details to bring are demographic and psychographic breakdowns, your current customer segments, and any first-party data your brand holds from past campaigns or CRM systems.

If your brand has customer interviews, sales call recordings, or survey data, bring those too. Raw audience insight outweighs any third-party persona template an agency could generate on their own.

Competitive context and your own market positioning

Agencies should know exactly who you’re competing against, how those competitors position themselves, and what differentiation your brand actually owns. As a rule of thumb, bring three to five competitors with notes on their messaging, the channels they dominate, and any whitespace you see in the market. Your current positioning statement belongs in this section, even if it needs work. An honest competitive brief shapes channel strategy, creative direction, and the tone of every campaign the agency builds for you.

Budget range, timeline expectations, and scope clarity

How to present your budget without underselling your ambition

Clients who refuse to share a budget force agencies to guess, and guessing produces misaligned proposals every time. Share a realistic range, not a ceiling disguised as a floor. How budget gets allocated across paid media, SEO, content, and creative production directly affects what an agency can deliver and in what timeframe. A $5,000/month budget and a $30,000/month budget require completely different scopes of work, channel mixes, and timelines.

Reframe the discomfort of sharing budget figures: your budget is a strategic constraint that shapes the right scope of work, not a negotiation card. Agencies that understand your budget build realistic plans. Agencies that don’t understand your budget build aspirational ones that fall apart when invoices arrive.

Realistic milestones for SEO, paid media, and content projects

Set timeline expectations using a simple framework: week one for access and baseline setup; weeks two through four for audits and strategic roadmaps; days 30 to 60 for first execution signals; days 60 to 90 for early performance trends; and 90-plus days for optimization and scale. This framework applies across service lines, but the pace varies. Paid media campaigns can launch in the first few weeks. Meaningful SEO ranking movement rarely appears before day 60, and often later than that.

Clients who understand this upfront don’t pull the plug on a sound SEO strategy at week five because they expected results at week three. Setting accurate expectations at kickoff protects both sides from frustration.

The assets, access, and brand materials your agency needs on day one

Platform access and account logins agencies request at onboarding

Agencies expect access to a specific set of platforms before work begins. The core list includes Google Ads (via delegated manager access or your 10-digit customer ID), Meta Business Manager covering Pages, Ad Accounts, and Pixels, Google Analytics 4, Google Tag Manager, Search Console, your website CMS, your email marketing platform, and domain or DNS access only when web changes are required. Agencies should be added as managers or granted editor-level permissions rather than receiving raw login credentials, for security reasons.

Brands that have this access prepared before kickoff can skip two to three weeks of back-and-forth. That’s not a small advantage, it’s the difference between launching a campaign in week three versus week six.

Brand assets, guidelines, and creative files to hand over

The creative materials your agency needs include logo files in both vector and web-ready formats, brand guidelines covering colors, typography, and tone of voice, approved messaging and value propositions, product and service descriptions, photography and video assets, and any existing ad creative or design source files. Brands without centralized brand guidelines signal disorganization that slows agency work from the first week.

If your brand guidelines live in someone’s head or across a scattered Dropbox folder, set aside a small block of time before the kickoff call to consolidate them. That upfront investment pays back immediately in faster creative production and fewer revision cycles.

Past campaign data and contractual terms to settle before work begins

What historical performance data to bring to the kickoff conversation

Past campaign performance is one of the most underused inputs in a marketing agency brief. Bring analytics data, previous ad account performance, past email benchmarks, and SEO baseline reports. Share what worked, what failed, and any campaigns the brand regrets running. Agencies use this data to avoid repeating expensive mistakes and to set realistic performance targets based on actual account history rather than generic industry averages.

An agency calibrating to real account history builds targets that make sense for your business. An agency working from industry benchmarks builds targets that may have nothing to do with your actual starting point.

Contractual items to clarify before the first invoice lands

Four contractual areas need clarity before work begins:

• Creative ownership:when deliverables transfer to you, what happens to unfinished work, and whether ownership is contingent on full payment.

• Account ownership: who controls logins and platforms at contract termination, and whether access ends immediately or after a transition period.

• Data rights: what client data the agency can use, analyze, or retain after the engagement ends, including customer lists and campaign data.

• NDA terms: what counts as confidential information, who can see it internally or externally, and how long the confidentiality obligation lasts.

Also address portfolio rights before signing. Whether the agency can feature the work in case studies or award submissions is worth clarifying upfront, not after the campaign goes live. These conversations feel minor until they become disputes. Locking them down at the start protects everyone and keeps the relationship focused on results instead of paperwork.

Show up ready and your agency can move from day one

What should you tell a marketing agency before starting? The six areas covered here map directly to the six decisions that shape every campaign: goals and KPIs, audience and competitive landscape, budget and timeline, assets and access, past campaign data, and contractual clarity. This is your agency brief template, the scope of work for a marketing agency relationship that actually moves fast. Brands who show up prepared can compress the agency learning curve from months to weeks, getting to live campaigns and measurable early returns while underprepared brands are still exchanging clarifying emails.

Gather these inputs, build your brief, and walk into that first meeting ready to move.
