1. Test the agency’s fit for your business model
Performance marketing discussions should start with a shared brief. Describe the offer, customer journey, service territory, available data and the demand your operations can fulfil. A completed ecommerce purchase is different from a sales-qualified B2B opportunity. An agency should recognise that distinction before recommending campaign structure or promising acquisition costs.
Listen to how your answers change the proposed work. Questions about stock, contribution margin and response times matter only if the recommendations reflect them. A new offer without validated demand may need a narrowly defined diagnostic or pilot before an ongoing retainer. Strong internal capacity may make advice more useful than outsourced execution. Do not assume that hiring an agency is automatically the best option for every company.
2. Ask for evidence behind experience and case studies
B2B lead generation offers a useful lens for evaluating lead-generation case studies: what happened after the form arrived? Ask about comparable sales cycles, buyers and operational constraints. A logo from your industry does not establish that the agency handled a similar challenge or caused the reported result.
Request the period, spend, objective, attribution setting and scope of the agency’s contribution. Discounts, product changes and existing demand may have influenced the outcome. An authorised reference conversation can provide operational context without requiring confidential client exports. If a candidate claims partner status or certification, ask for a current official verification link and the credentials of the people assigned to your account. Neither a badge nor a past result guarantees future performance or privileged support.
FROM READING TO A NEXT STEP
Build an agency brief you can compare
Share your objective, current account situation and creative capacity. Discuss the work Prix can own and the decisions that remain with your team.
3. Examine creative production and testing judgement
Ad creative production should be evaluated through the customer problem and supporting evidence. Give the candidate one product and ask how it might address two objections, such as durability and installation effort. Those are separate hypotheses. Changing the background colour alone does not establish that either message works. Ask how the proposed ad connects to the landing page.
If your team supplies assets, define the agency’s responsibility for briefing, editorial feedback, format checks and interpretation. Discuss music, talent, source files and licensing separately. Refresh decisions should consider delivery, outcomes, offer changes and production capacity, rather than a fixed calendar that ignores your account. A smaller test can be sensible when budget cannot support many simultaneous variations.
Hypothesis
Identify the buyer objection and evidence the advertisement will address.
Acceptance
Name the people responsible for formats, rights, revisions and approval.
Learning
Explain how the result will change the next creative brief.
4. Ask the team to explain its measurement plan
Server-side tracking setup should come with an understandable event map. What happens on the website, when is it recorded, where is it sent and who investigates failures? Privacy choices and applicable processing requirements remain relevant to server-side transmission. A form opening, a submission attempt and a successfully stored enquiry are different events.
When browser and server integrations report the same action, ask for evidence that duplicates are handled. The need for an additional integration depends on the existing platform, scope and maintenance capacity; not every business requires the same architecture. The agency should explain implementation costs and ongoing ownership. Differences between Meta, analytics and CRM figures should be investigated and documented, rather than hidden by forcing unlike systems into one supposedly perfect number.
5. Review account security and authority to make decisions
Remarketing management also depends on who may approve audience and delivery changes. Establish the current owner and access arrangements for the business portfolio, ad account, Page, Instagram account, dataset and catalogue. Company control and the agency’s day-to-day task permissions are separate decisions. Record approval for spend increases as well as who can stop a campaign.
Meta supports sharing selected assets with a partner and assigning relevant tasks, subject to the portfolio’s control and ownership requirements. Use suitable access and two-factor authentication instead of sharing personal passwords. Ask how employee changes and departures are handled. Do not assume every history, audience or asset can move seamlessly at termination: platform ownership constraints and deliverable files need separate checks.
6. Compare total cost and reporting on compatible terms
CAC, ROAS and MER help translate a proposal into business decisions. Separate media spend, management, production, tools, taxes and technical work. A flat retainer, spend-based fee or performance component can only be compared once the deliverables are equivalent. Where spending more also raises the agency’s fee, clarify who approves the change and what evidence supports it.
Request a metric glossary, data sources and a sample interpretation. Each reporting period should explain which assumption changed, which problem was investigated and what decision comes next. If the team cannot access qualified opportunities or completed net orders, its report should state that limit. Confident profit claims built on incomplete data deserve follow-up questions. Agree a communication rhythm your business can actually maintain.
| Area | Evidence requested | Decision supported |
|---|---|---|
| Scope | Separate production, setup and management outputs | Compare the same work |
| Data | Attribution, returns and lead-quality definitions | Interpret compatible results |
| Fees | Extras and budget-increase approval | Understand total cost |
| Communication | Delivery owner, backup and response arrangement | Assess continuity |
7. Make the choice through a bounded working plan
For performance marketing, ask shortlisted candidates to explain the same small problem. A sanitised data summary may be sufficient without access to confidential accounts. The useful output is a starting diagnosis, proposed change, responsible person, cost limit and evaluation method. Avoid demanding a complete unpaid strategy or documents that would breach another client’s confidentiality.
Assess whether the delivery team can work with your approval speed and available assets. Name decision makers when several departments are involved. You can score proposals against your priorities, but that score is your buying tool, not an independent market ranking. Before signing, perform a separate document review covering scope, access and exit. Apply these questions to Prix as well: a clear boundary around our contribution is more useful than an unqualified growth promise.
Shared brief
Give each candidate the same objective, constraints and available starting data.
Evidence interview
Review a relevant case, a reporting example and the team doing the work.
Bounded start
Agree deliverables and evaluation conditions in writing before implementation.
BEFORE YOU DECIDE
Frequently asked questions
What should I check first when choosing a Meta ads agency?
Start with business fit. Ask how the agency defines your buyer journey, operational capacity and measurable outcome. An attractive portfolio is useful context, but does not establish an appropriate acquisition plan.
Does the agency need experience in my exact industry?
It can help, but comparable buyers and sales cycles are also relevant. Examine the actual challenge, work performed and contribution rather than treating a logo as sufficient evidence.
Does Meta partner status guarantee better results?
No. Verify any partner or certification claim through an official link. Then assess the assigned people, their responsibilities and whether the proposal fits your business.
Is the cheapest agency the best value?
Not necessarily. Compare equivalent scope including production, tools, implementation and revisions. A lower headline fee can exclude work your campaign still needs; continuity and delivery risk also matter.
Should I share my personal password with the agency?
Use appropriate platform asset and task permissions instead of a shared password. Check the existing ownership arrangement, authorised people and two-factor authentication before granting access.
How long should I wait for results?
There is no universal period. Data volume, sales cycle, offer and starting problems differ. Agree initial deliverables and evaluation conditions, and distinguish learning outputs from commercial outcomes.
