In short: Review a contractor’s agreed work, operating commitments, and contribution to business results on separate lines. This makes accountability clear while showing where market conditions, client decisions, sales follow-up, or measurement affect the outcome.
A marketing partner can influence pipeline, but the path from an ad or campaign to collected revenue includes decisions and conditions across the business. A useful review connects the provider’s work to business results without assigning every change to one person or one channel.
Start with the assignment
Before the review period begins, write down four things:
- The business result the engagement is meant to support
- The deliverables and operating commitments the contractor owns
- The inputs and decisions that depend on your team or another partner
- The data source and period you will use to assess progress
This short record prevents the review from drifting into a debate about what the engagement was supposed to include. It also gives both sides a way to identify a missed commitment, a blocked task, or an outcome that needs more time to mature.
For a new or renewed engagement, turn responsibilities into observable work and acceptance checks in the statement of work.
Review three layers of performance
1. Work the contractor can deliver directly
Start with commitments that sit within the provider’s day-to-day control: agreed campaigns built and checked, analysis delivered on time, landing-page drafts submitted to the agreed standard, tracking issues documented, and recommendations followed by a decision or next step.
Assess each item against its scope, due date, quality criteria, and evidence. If a task depended on client access, approval, or data, record that dependency and when it was available. The contractor remains responsible for raising a blocker early and explaining its effect on delivery.
2. Indicators the contractor can influence
Some measures sit between execution and the final business result. Examples include eligible traffic, cost per qualified inquiry, form completion, or movement between funnel stages. The contractor may influence these through targeting, creative, testing, and optimization, while budget, offer, site experience, audience demand, and sales response also contribute.
Agree on the definition, owner, data source, and review period for each measure. Then ask what changed, what evidence supports the explanation, and what action follows. A metric without an agreed definition can create a false disagreement about performance.
3. Business outcomes shared across the team
Pipeline, new-customer revenue, retention, and cash collected matter to the business. Track them alongside delivery and leading indicators, with the sales cycle and conversion delay in view. Use a mature cohort or a clearly labeled interim view when the full result has not had time to develop.
Google’s campaign guidance names conversion delays, budget and settings changes, auction dynamics, account conditions, and shifts in market interest among the factors that can change performance. The contractor remains responsible for investigating relevant factors and recommending a response. Include material changes when interpreting the result.
Set the measurement rules before the period starts
Choose a baseline and a review window that fit the work. Record changes that could affect the comparison, such as a budget shift, new offer, site release, tracking repair, pricing change, sales coverage gap, or a material change in campaign settings.
For each measure, keep four fields together: the definition, source of truth, responsible owner, and date range. If the reporting cadence should trigger operating decisions, use the agency reporting cadence guide to set the meeting and escalation rhythm.
The U.S. Federal Acquisition Regulation calls for measurable service standards and a method for assessing contractor performance in performance-based federal service contracts. The UK Cabinet Office’s contract-management guidance likewise connects KPIs to obligations, outcomes, and factual performance reviews. Public-sector references offer measurement examples. For private work, use the scope and terms agreed for that engagement.
Use a compact scorecard
A monthly or quarterly review can fit on one page:
- Committed work: planned, delivered, accepted, late, or blocked—with evidence
- Operating quality: review response commitments, quality checks, documentation, and early escalation
- Optimization: list the hypothesis, evidence, decision, owner, and follow-up date
- Shared indicators: show the agreed funnel or economic measures with the period, data source, and known changes
- Business outcome: state the current result, cohort maturity, and what can or cannot yet be concluded
- Next action: record one action, its owner, and a due date
Use simple statuses such as met, partly met, and missed for direct commitments. Add a short explanation and evidence. For shared measures, write what the data shows and what the team will test or investigate next. A growing list of disconnected KPIs usually makes review harder; the UK guidance recommends keeping measures few enough to manage and reassessing whether they remain useful.
Turn a miss into a specific decision
When a commitment slips, identify the main cause: provider execution, a client dependency, data or tracking, an external change, or a combination. Agree on the correction, the person who owns it, and when the team will check again.
When a business result is below plan, ask the contractor to trace the path through available evidence: delivery, traffic or audience, inquiry quality, sales follow-up, conversion timing, and economics. End the review with a clear decision to continue, adjust, test, narrow the scope, or change ownership. Record the evidence, owner, and follow-up date.
A quick review record
- Business outcome: ______
- Contractor-owned commitments and acceptance evidence: ______
- Client or partner dependencies: ______
- Shared indicators, source, and period: ______
- Material changes and measurement limits: ______
- What the evidence supports: ______
- Next action, owner, and due date: ______
A fair performance review keeps the provider accountable for agreed work and makes shared outcomes easier to discuss. If pricing depends on a result, agree on its definition and evidence before the engagement begins; see the guide to comparing marketing agency pricing models.
If the scope or evidence remains unclear, request a marketing diagnostic to review the working assumptions and next decision.
