How to Manage a Marketing Agency (and Know If It's Working)

TL;DR

Own every ad account, analytics property and creative file before you judge an agency. Then give it written briefs, hold it to the KPIs it controls, review weekly, monthly and quarterly, and score it every quarter. If the score stays low after one written fix plan, renegotiate the scope or replace the agency.

· Published · Updated

Managing a marketing agency comes down to four habits: you own the accounts and data, you give the agency briefs it can execute, you judge it on metrics it actually controls, and you review it on a fixed rhythm. Founders without a marketing lead tend to skip all four, then discover months later that nobody can say whether the agency is working.

Set up ownership first: ad accounts, analytics and creative files

Before you judge performance, make sure you could end the relationship tomorrow and keep everything you paid for. When I step into a company that runs agencies, this is the first thing I check, and it’s one of the most common gaps I find.

The rule is simple: your business creates every account, your payment method pays for media, and the agency gets user or partner access.

AssetWho should own itWhat the agency gets
Google Ads accountYour company, created under your Google loginUser access, or a link to the agency’s manager account
Meta ad account, Page and pixelYour own Meta business portfolioPartner access to specific assets
LinkedIn ad account and company pageYour companyCampaign Manager role on the ad account; the lowest page role that lets them run ads
GA4 property and Google Tag Manager containerYour company’s Google accountEditor or Marketer in GA4; Edit access in GTM, with Publish only if they need it
Domain, website, landing page toolYour companyEditor, never owner
CRM and email platformYour companyA user seat with limited permissions
Creative, copy and source filesYou, once paid, per the contractUpload rights to a shared drive you own

Run this checklist once, then again every quarter:

  • At least two people at your company have admin rights on every platform
  • Media is billed to your card or invoice account; if the agency rebills media, you see the platform invoices
  • The contract says work product, including layered and source files, belongs to you on payment
  • Final and source creative files land in a folder you own every month
  • An offboarding clause requires the agency to hand over access, naming conventions and documentation within a set number of days

Writing a brief an agency can actually execute

Most weak agency work traces back to a weak brief. “Get us more leads” is a wish, not a brief. A brief the agency can execute answers nine questions:

  1. Business goal, as a number. A hypothetical example: “20 sales-qualified demos a month from paid channels at or below $500 each.”
  2. Audience. Who buys, who doesn’t, and which segments to exclude.
  3. Offer and message. What you’re asking people to do and why they should do it now.
  4. Budget and pacing. Monthly cap and how much it can flex.
  5. Constraints. Brand rules, claims you can’t make, regions and compliance limits.
  6. Available assets. Existing creative, customer proof, landing pages, and who produces anything new.
  7. Success metric and system of record. Which number counts, and where it’s measured: your CRM or store, not the ad platform.
  8. Decision rights. What the agency can change without asking, such as bids or budgets within a set range, and what needs your sign-off, with a turnaround time.
  9. Deadlines. Launch dates and when the first results review happens.

A useful test: give the brief to someone who missed the kickoff call. If they can’t tell you what success looks like and what’s off-limits, rewrite it.

KPIs the agency controls vs influences

Split every KPI into three layers before the agency starts. This single step prevents most arguments later.

LayerExamplesOwnerHow to use it
ControlsLaunch dates hit, creative variants shipped, spend pacing, tracking accuracy, click-through rate, cost per click, conversion rate on pages they buildAgencyHold them accountable; this is the contract
InfluencesCost per qualified lead, sales-qualified lead rate, pipeline from paid, new-customer CAC, marketing efficiency ratio (MER)SharedSet targets together; review the full chain when they miss
Doesn’t controlClose rate, pricing, product fit, sales follow-up speed, retentionYouDon’t blame the agency, but expect them to flag problems they see

The mistake runs both ways. Founders hold agencies to revenue they can’t control, so good agencies get fired for sales problems. Agencies hide behind the metrics they do control, so a strong click-through rate covers for an empty pipeline.

My working rule: judge the agency’s execution on the controlled layer, and make renewal decisions on the influenced layer. Measure the influenced layer in your CRM or store backend, and bring those numbers to the review yourself.

The weekly, monthly and quarterly review rhythm

A fixed rhythm replaces vague “how’s it going” calls with decisions.

CadenceLengthAgendaOutput
Weekly30 min, or asyncSpend vs pace, what launched, what’s blocked, what’s nextBlocker list with owners and dates
Monthly60 minControlled KPIs vs target, influenced KPIs from your CRM, tests run and what they taught, next month’s planUpdated plan and test queue
Quarterly90 minScorecard, strategy check, scope and fee reviewKeep, fix or change decision

Three habits make the rhythm work. Ask for the report 24 hours before the meeting, so the meeting is for decisions rather than reading. Keep a shared test log with the hypothesis, result and next step for every test. And split the data duties: the agency brings platform numbers, you bring CRM or store numbers, and the conversation happens in the gap between them.

Red flags in agency reporting

Reports can look busy and still hide a problem. Watch for these:

  • The metrics change month to month. New KPIs appear when old ones slip.
  • Only platform-reported conversions. Platforms overlap and claim credit generously, so nothing is reconciled against your CRM or store.
  • Conversions that aren’t business outcomes. Page views, scroll depth or engaged sessions counted as conversions next to real leads.
  • Branded search inside the totals. Blended results hide that many “wins” came from people already searching for your name.
  • No test log. Nobody can say what was tried, what was learned or what changes next.
  • Screenshots instead of access. You see curated images, not the live account.
  • Every miss has an outside cause. The algorithm, seasonality or a learning phase is a fair answer once, not three months running.
  • Spend doesn’t reconcile. Reported spend differs from platform invoices, with no explanation.
  • Activity reported as results. A count of “optimizations made” tells you nothing about outcomes.

If paid search is a large part of the scope, check the account yourself each quarter with a Google Ads audit checklist, or have someone independent do it.

When to renegotiate, replace or bring work in-house

Use the scorecard trend, not a single bad month, to decide.

SituationLikely move
Execution is solid, but results are soft because scope or budget is spread too thinRenegotiate: fewer channels, more depth
Retainer hours go to reporting and meetings instead of workRenegotiate the fee structure or automate reporting
Controlled KPIs missed two months running after a written fix planReplace
Reporting red flags, or access withheld when you ask for itReplace, starting with recovering access
Work is steady and core, volume justifies a salary, and someone can manage the hireBring it in-house
Work is spiky or needs rare skills, such as creative bursts or tracking buildsKeep it external

When you replace an agency, recover access and export data first, then give notice. Where the contract allows, overlap old and new agencies for a few weeks so campaigns don’t go dark during the handover.

Sometimes the real problem isn’t the agency. It’s that nobody on your side can set strategy and hold vendors to it. That’s a leadership decision, and fractional CMO vs full-time CMO vs agency walks through the options. Running agency briefs, reviews and scorecards is a core part of my fractional CMO work, so founders get a clear read without managing it themselves.

Agency scorecard template

Score each area from 1 (poor) to 5 (excellent) at the quarterly review, multiply by the weight and add the results.

AreaWhat to scoreWeightScore (1-5)
Ownership and accessYou own every account; access is current; files delivered10%
ExecutionLaunches on time, creative volume, sticks to the brief20%
Controlled KPIsHit agreed targets on metrics they control25%
Influenced outcomesQualified leads, pipeline, CAC or MER trend in your systems20%
Reporting qualityStable metrics, reconciled to CRM, clear test log15%
ProactivityBrings ideas, flags problems outside their scope10%

A hypothetical example: scores of 5, 4, 3, 3, 2 and 4 give a weighted total of 3.35, which lands in the fix-plan band. These are my working thresholds, not industry benchmarks:

  • 4.0 and above: keep, and consider expanding scope.
  • 3.0 to 3.9: agree on a written fix plan with named actions and recheck in 60 days.
  • Below 3.0 twice in a row: start the replacement process.

Share the scorecard with the agency at kickoff. Good agencies want to know the rules they’ll be judged by, and the ones that resist it tell you something too.

FAQ

Frequently Asked Questions

How often should I meet with my marketing agency?

Weekly for about 30 minutes on pacing, launches and blockers, monthly for an hour on results against targets, and quarterly for a business review covering scope, fees and the scorecard. If you need more meetings than that, the brief is usually unclear.

Should my agency own our ad accounts?

No. Create the ad accounts, analytics property and tag manager container under your own business, pay for media with your own billing method, and grant the agency access. When the relationship ends, you remove their access and keep the full history.

How long should I give a new agency before judging results?

Judge setup and execution in the first 30 days and leading indicators, such as qualified lead volume and cost, by roughly day 60 to 90. Revenue in longer B2B sales cycles can take a quarter or more to show, so hold the agency to what it controls first.

When does it make sense to bring agency work in-house?

When the work is steady and core to how you grow, the volume justifies a full-time salary, and someone on your team can manage the hire. Keep work that is spiky or needs rare skills with specialists.
