Why Your Media Agency Review Is Long Overdue (And How to Run One Without Blowing Up the Relationship)

Most brands go years without a proper agency review. Here's how to run one that's honest, structured, and doesn't poison the relationship in the process.

Most brands have not run a proper agency review in three or four years. The last one, if there was one, was probably triggered by a crisis, a missed campaign, a budget blowout, a change in CMO, rather than by any kind of deliberate governance. In the years since, the relationship has drifted. The agency has gotten comfortable. Nobody has asked a hard question in a while. Performance has become something described in percentages that look fine on a slide and mean almost nothing in practice.

That is not a criticism of agencies specifically. It is a description of what happens to any vendor relationship with no structured accountability built into it. The work expands to fill the space available, fees creep in increments too small to individually flag, and both sides learn to manage expectations downward rather than have the uncomfortable conversation that would actually fix something.

The review is not about finding a reason to fire anyone. It is about finding out what you are actually getting for the money.

What a real review looks at

Start with the commercial structure. Pull the contract, the rate card, and the last two years of invoices, and check what you paid for against what actually got delivered. Most brands find at least one or two line items they cannot fully explain once they look closely. That is rarely fraud. It is just what happens by default when nobody on the client side is actively managing the commercial relationship, and the agency, reasonably, is not going to flag it for you.

Then look at performance, not the metrics in the monthly deck, but the actual business outcomes the relationship was meant to drive. If you cannot draw a clean line from agency activity to a result the business cares about, that is a structural problem. Either the brief was never tight enough to measure against, or the work has been quietly optimizing for the wrong thing, or both, and neither side noticed because nobody was checking.

Finally, look at the team. Are the senior people who won the pitch still anywhere near your account? This is one of the oldest complaints in the industry and one of the most consistently ignored, mostly because raising it feels petty in the moment. It is not. You are paying for a specific level of expertise. You are entitled to know whose expertise you are actually getting.

Running it without damaging the relationship

The relationship has real value, and running a review does not mean you are heading for the exit. The agency does not need to feel like it is on trial.

Be direct about what you are doing and why. "We're running a structured review of our major vendor relationships this year" is honest and neutral, and it signals seriousness without signaling an ending. Most agency leaders, treated like adults, respond well to that. They want to know where they actually stand. The ones who get defensive about it are usually the ones with something to hide.

Bring a clear scorecard into the room. Decide what good looks like before the conversation starts, not during it. That keeps things factual and cuts the chance it turns into a personality conflict about something said in a meeting eight months ago.

And if you are genuinely considering going to market, say so. Pretending otherwise when you are not wastes everyone's time and tends to surface anyway, usually at the worst point in the process.

What comes out the other side

A serious review ends in one of three places: a renegotiated, tighter version of the current relationship; a competitive pitch that either reaffirms the incumbent with real conviction or brings in someone better; or a managed transition done properly instead of in a rush. All three are legitimate outcomes. The one outcome worth avoiding is the one most companies are actually in, a relationship nobody has properly examined in years, running on autopilot, with no one fully sure whether it is working.

Your media budget is very likely one of the largest line items on your marketing P&L. It deserves the same rigor you would apply to any other major vendor relationship of that size. The review does not have to be adversarial. It does have to happen.
