Marketing audit vs. an in-house review
Your team can review the numbers themselves — for free. The question is whether they can see what an outsider sees. Here is how an independent audit compares with an in-house review on objectivity, benchmarks, speed and cost.
| Independent audit | In-house review | |
|---|---|---|
| Objectivity | Outside view, no internal politics | Knows the context, carries the bias |
| Benchmark | A 74-audit base to compare against | Only your own history |
| Bandwidth | Dedicated, time-boxed | Squeezed between business-as-usual |
| Speed | 5–7 days | As long as it takes to find the time |
| Cost | Fixed fee | "Free," but real opportunity cost |
| Best for | An objective, benchmarked diagnosis | Continuous monitoring you own |
Which should you choose?
Your team knows the context an outsider never will — which is exactly why an in-house review is good at spotting known issues and bad at spotting the ones everyone has stopped seeing. An audit brings two things in-house can't easily manufacture: objectivity and a benchmark. Use in-house for continuous monitoring; use an audit when you need an outside, benchmarked read on where the margin is going.
Common questions
Why can't my team just do the audit?
They can review — but they carry the same assumptions that let the leak form, and they have no outside benchmark. An audit adds an objective view and a 74-audit comparison base, in a dedicated 5–7 day window instead of squeezed around day-to-day work.
What does an audit see that in-house misses?
Mostly the invisible: non-incremental spend, attribution inflation and mispriced offers that a healthy blended ROAS hides. These are hard to see from inside because the top line looks fine.
Is a one-off audit enough, or do I need monitoring?
An audit is the diagnosis; monitoring is the maintenance. Most teams audit to find the leaks, fix them, keep an eye on the metrics in-house, and re-audit when spend or strategy shifts materially.
