How to Audit Your Current Performance Marketing Agency in 48 Hours

Key Takeaways

• You can audit your current performance agency in about 48 hours by checking the specific things that quickly reveal quality — you don't need a long engagement to find out.
• Check measurement honesty: does it report incremental, reconciled results, or just platform ROAS and last-click (which flatter the agency)?
• Check incrementality (has it proven your growth is caused?), incentive alignment (does the pricing reward your profit or your spend?), and ownership (do you own your accounts and data?).
• Check who actually does the work — experienced people, or juniors after a senior pitch?
• Red flags in any of these signal a problem worth addressing.
• Decide: keep an agency that passes, push a fixable one to fix its issues, replace one with fundamental problems (misaligned incentives, dishonest measurement, no ownership).

You Can Learn Most of It Quickly

If you suspect your performance marketing agency might not be delivering — or you just want to verify that it is — you do not need to wait for a lengthy engagement to reveal the truth; a focused 48-hour audit of the right things reveals most of what matters about an agency's quality. It is a common misconception that judging an agency's quality requires a long time (waiting for results to play out, giving the relationship time), when in fact most of what determines an agency's quality can be assessed quickly by checking the right things — the measurement honesty, the incrementality practice, the incentive alignment, the ownership terms, and who does the work. These are things you can check in a couple of days (48 hours), and they reveal most of what matters about whether the agency is genuinely delivering or quietly underperforming.

The reason you can learn most of it quickly is that the things that most determine an agency's quality are structural and checkable, not dependent on long observation — whether the measurement is honest, whether incrementality is proven, whether incentives are aligned, whether you own your accounts, and who does the work are all things you can assess quickly by examining the agency's practices, not things you have to wait to observe. An agency's measurement honesty (does it report incremental reconciled results?), its incrementality practice (has it ever proven your growth is caused?), its incentive alignment (how is it paid?), your ownership (do you own your accounts?), and who does the work (experienced people or juniors?) are all checkable quickly by examining the agency's practices and your arrangements — they do not require a long engagement to reveal. So most of what determines the agency's quality is quickly checkable, which is why a focused 48-hour audit can reveal it.

This is empowering, because it means you do not have to endure a long, uncertain engagement to find out whether your agency is delivering — you can find out quickly by checking the right things, and act on what you find. Rather than waiting and hoping (giving the agency time while uncertain whether it is delivering), you can conduct a focused audit that reveals the agency's quality in about 48 hours, and then decide whether to keep, fix, or replace the agency based on what you find. So if you have concerns about your agency (or just want to verify it), you do not have to wait — you can audit it quickly by checking the specific things that reveal quality, which is what this guide provides: the things to check, the red flags, and how to decide. A 48-hour audit of the right things reveals most of what matters, which lets you assess and act on your agency's quality quickly rather than enduring uncertainty. The audit checks the substance that determines quality in any performance marketing partner.

Check Measurement Honesty and Incrementality

The first and most revealing things to check are the agency's measurement honesty and its incrementality practice, because how an agency measures reveals whether it is accountable to real results or hiding behind flattering metrics — which is one of the strongest signals of quality. On measurement honesty, check whether the agency reports incremental, reconciled results tied to your real revenue, or just platform ROAS and last-click attribution (which systematically flatter the agency). An agency that reports platform ROAS and last-click has chosen metrics that flatter it (the platforms grade their own homework, last-click over-credits the final touch), so its reported results may overstate its contribution; an agency that reports incremental, reconciled results (tied to your actual booked revenue) has chosen to be held to what is real. So checking the agency's measurement — does it report real, reconciled, incremental results, or flattering platform metrics? — quickly reveals whether it is accountable to real results or hiding behind flattering metrics.

On incrementality, check whether the agency has ever proven that your growth is caused by its work — through holdout tests, geo experiments, or other incrementality measurement — or whether it just claims credit for growth via platform ROAS. An agency that has run incrementality tests (measuring the true causal contribution of its work) has proven its value is real; an agency that has never run an incrementality test, and just claims credit for growth via platform metrics, has never proven that its work is actually causing the growth it claims. So checking whether the agency proves incrementality (has it run holdouts or geo tests?) quickly reveals whether its claimed results are proven-causal or just claimed-via-flattering-metrics — a strong signal of quality and honesty.

Together, measurement honesty and incrementality reveal whether the agency is accountable to proven, real results or hiding behind flattering, unproven metrics — which is one of the fastest and strongest ways to assess quality. An agency that reports incremental, reconciled results and proves incrementality is accountable to real, proven results (a strong quality signal); an agency that reports flattering platform metrics and never proves incrementality is hiding behind unproven, flattering numbers (a strong red flag). So checking these two — measurement honesty (real reconciled results vs flattering platform metrics) and incrementality (proven causal vs just claimed) — quickly reveals a lot about the agency's quality and honesty, which is why they are among the first and most revealing things to check in a 48-hour audit. An agency's approach to measurement and incrementality reveals whether it is willing to be held to real, proven results or prefers to hide behind flattering, unproven metrics — a fast, strong signal of quality.

Check Incentives and Ownership

The next things to check are the agency's incentive alignment and your ownership of your accounts and data, because these structural arrangements reveal whether the agency's interests are aligned with yours and whether you are captive — both strong, quickly-checkable signals of the relationship's health. On incentives, check how the agency is paid, and whether the pricing rewards your profitable results or just your activity — the common misalignment being a percentage-of-spend model, which pays the agency more when you spend more (whether or not it works), incentivizing it to grow your spend rather than your profit. An agency paid a percentage of your spend has incentives that point toward growing your budget (regardless of profit), a misalignment with your interest; an agency paid in a way that rewards your profitable results (flat, scoped, or outcome-based) has aligned incentives. So checking the pricing model (percentage of spend vs aligned) quickly reveals whether the agency's incentives are aligned with your interest or point toward growing your spend.

On ownership, check whether you own your ad accounts, tracking, and data, or whether the agency controls them — because if the agency controls your accounts and data, you are captive (leaving means losing your infrastructure), while if you own them, you are free. An agency that controls your ad accounts, tracking, and data makes you captive (you cannot easily leave without losing your accounts, measurement, and data), which is both a red flag (it plans for your dependency) and a practical trap (you are stuck); an agency under which you own your accounts, tracking, and data leaves you free (you can leave and take your infrastructure). So checking ownership (do you own your accounts and data, or does the agency control them?) quickly reveals whether you are captive or free — a strong signal of the relationship's health and the agency's posture.

Together, incentives and ownership reveal whether the agency's interests are aligned with yours and whether you are free or captive — structural signals of the relationship's health that you can check quickly. Aligned incentives and your ownership indicate a healthy relationship (the agency's interests align with yours, and you are free); misaligned incentives (percentage of spend) and agency control of your accounts (making you captive) indicate an unhealthy relationship (the agency's interests point elsewhere, and you are trapped). So checking these two — incentive alignment (aligned vs percentage-of-spend) and ownership (you own vs agency controls) — quickly reveals the structural health of the relationship, which is why they are key things to check in a 48-hour audit. These structural arrangements (how the agency is paid, who owns your accounts) reveal whether the relationship is set up in your interest or against it — a fast, strong signal that complements the measurement and incrementality checks.

Check Who Actually Does the Work

A further thing to check — quickly revealing and often overlooked — is who actually does the work: whether experienced people are running your account, or whether junior people are running it after a senior team won the pitch. The seniority gap between the people who pitch and the people who deliver is the most common broken promise in the agency industry, so checking who actually runs your account (their experience and seniority) quickly reveals whether the capability you were promised is actually being applied to your account. An account run by experienced people gets the capability you were promised; an account run by junior people (after a senior pitch) gets diluted capability, however good the agency's senior people are. So checking who runs your account (experienced or junior?) quickly reveals whether the capability is reaching your account.

You can check this quickly by finding out who specifically runs your account day to day and assessing their experience and seniority — do you know who runs your account, and are they experienced, or is it junior people you rarely interact with? If experienced people run your account (and you interact with them), the capability is reaching your account; if junior people run it (and the senior people you met in the pitch are absent), the capability is diluted. So checking who runs your account (and their experience) is a quick way to assess whether the promised capability is actually being applied — a common gap that is quickly checkable.

This check complements the others because the capabilities and structural health checked elsewhere are only valuable if capable people are applying them to your account — so checking who does the work verifies that the capability is reaching your account. An agency with good measurement, aligned incentives, and your ownership, but with junior people running your account, is not delivering its capability to you (the capability is diluted by the delivery); an agency with those things and experienced people running your account is delivering its capability. So checking who does the work verifies that the capability reaches your account, completing the picture of whether the agency is genuinely delivering. Together with the measurement, incrementality, incentives, and ownership checks, checking who does the work gives you a fast, comprehensive assessment of the agency's quality — whether it is honest and accountable (measurement, incrementality), whether the relationship is healthy (incentives, ownership), and whether the capability reaches your account (who does the work). These five checks, done in about 48 hours, reveal most of what matters about your agency's quality.

Deciding: Keep, Fix, or Replace

With the audit done (measurement honesty, incrementality, incentives, ownership, who does the work checked), you use what you find to decide whether to keep, fix, or replace the agency — a decision the audit's findings inform, because the findings reveal whether the agency is genuinely delivering, fixably underperforming, or fundamentally problematic. An agency that passes the checks (honest reconciled measurement, proven incrementality, aligned incentives, your ownership, experienced delivery) is genuinely delivering and worth keeping; an agency with fixable issues (some checks passed, some failed in ways that could be fixed) might be pushed to fix them; an agency with fundamental problems (misaligned incentives, dishonest measurement, no ownership, junior delivery) has deep issues that often warrant replacement. So the audit findings inform the keep/fix/replace decision by revealing where the agency stands.

The decision depends on the nature of the issues found — fixable issues (that the agency could address) warrant pushing the agency to fix them, while fundamental problems (structural misalignments that are unlikely to change) warrant replacement. If the audit reveals fixable issues (a measurement gap the agency could fill, a delivery issue it could address), you can push the agency to fix them (raising the issues, requiring improvement) and reassess; if it reveals fundamental problems (misaligned incentives from a percentage-of-spend model it will not change, dishonest measurement it defends, agency control of your accounts it will not relinquish, a seniority gap it will not close), these are deep structural problems unlikely to change, which often warrant replacement. So the decision depends on whether the issues are fixable (push to fix) or fundamental (replace) — which the audit's findings reveal.

The value of the fast audit is that it lets you make this decision quickly and on evidence, rather than enduring a long, uncertain relationship — you assess the agency in 48 hours, then decide (keep, fix, or replace) on what you find. Instead of waiting and hoping (uncertain whether the agency is delivering), you audit it quickly (checking the things that reveal quality) and decide on the evidence (keep an agency that passes, push a fixable one to improve, replace a fundamentally problematic one), acting on your findings rather than enduring uncertainty. So the 48-hour audit gives you the evidence to decide about your agency quickly and confidently — keep the one that is genuinely delivering, push the fixable one to fix its issues, and replace the one with fundamental problems — which is far better than enduring a long, uncertain relationship uncertain whether the agency is delivering. Auditing your agency in 48 hours, and deciding on the evidence, is how you take control of the agency relationship — assessing quickly, acting on evidence, and ensuring you are working with an agency that genuinely delivers rather than one that quietly underperforms.
