A well-run agency review delivers agency review value far beyond choosing a new media partner: it forces your organisation to articulate strategy, benchmark market knowledge, and build procurement discipline that persists long after the contract is signed. Most advertisers treat the review as a means to an end. The ones who get the most from it treat it as structured learning. In addition the conversations and information exchange with the media agencies usually provide a lot of learnings.
You have probably been through a review where the winning agency was announced, the debrief emails went out, and everyone moved on. Slide decks were archived. Scoring sheets were filed. Two years later, half the team has turned over and the institutional knowledge that surfaced during the pitch exists nowhere except in someone’s inbox. That is the most common way to waste a review.
What an agency review actually puts on the table
When agencies respond to your brief, they are, in effect, auditing your current approach. Depending on the brief they could for example map your audience, challenge your channel assumptions, model your budget allocations, and propose how they would do things differently. You receive several of these audits simultaneously, each built by specialists who spend every working day on media strategy, buying and optimizing.
The material that lands in your inbox during a pitch is some of the most concentrated media thinking your team will ever see applied directly to your business. The question is whether you extract that thinking or simply use it to score a pitch.
This is where The media brief: the foundation of an agency selection becomes critical context. The quality of what agencies return in their proposals is a direct function of the quality of the brief you issued.
Agency review value: the five things your team learns
The agency review process, when run with discipline, trains your team in five areas that no internal workshop replicates.
Market benchmarking. Agencies will present media cost benchmarks, audience reach data, and channel performance expectations. Your team will hear what the market actually charges for the inventory you buy, which is often different from what you currently pay. That gap is information. It tells you whether your current agency is performing or coasting.
Strategic translation. A well-structured brief forces your team to translate business objectives into media objectives. That translation is harder than it sounds. The review process requires it to be done in writing, tested against agency responses, and defended in presentations. Teams that go through this exercise once find subsequent planning cycles significantly easier.
Evaluation rigour. Scoring agency proposals teaches your team to separate strong claims from substantiated ones. Agencies will present audience models, attribution frameworks, and cost-per-outcome projections. Deciding which of these are credible, and why, is an analytical skill. Your team develops it by doing it.
Commercial negotiation literacy. Fee structures, trading terms, data ownership clauses, performance commitments: these surface during a review, and most internal teams have limited exposure to them before their first pitch. A well-run review, gives your team the time and the context to understand what they are agreeing to and how to interpret such data on a day to day basis. Keep in mind marketing and brand managers do not automatically have a deep media knowledge.
Brief writing discipline. As covered in Why does the brief decide more than the presentations?, the brief is where most reviews are won or lost before a single agency has seen it. Teams that write a genuinely rigorous brief learn more about their own strategy in the drafting than they do from most internal planning sessions.
What most teams do instead
Most teams run the review as a procurement exercise and stop there. The focus goes on scoring matrices and pricing negotiation. The strategic material in the proposals is reviewed once, lightly, then set aside. The lessons from the process are not documented. The people who ran the review move on.
This is not a criticism of procurement discipline. Scoring and negotiation matter enormously. But treating the review as purely a vendor selection exercise leaves a positive side effect of its value uncaptured.
The parallel in other disciplines is clear. A thorough audit of any function produces findings that apply beyond the immediate remediation. The same is true of a media agency review. The commercial intelligence, the way of working, the media landscape, the market benchmarking, and the strategic challenges raised by competing agencies are assets. They depreciate if they are not captured and institutionalised. We are talking about building corporate memory.
For teams operating across multiple markets, the learning compounds. Understanding how different agencies approach, for example, advertising in Southeast Asia versus a domestic market reveals structural differences in media buying practice that no internal briefing document would surface.
How to build institutional knowledge from a review
Three practices convert a review from a one-time event into a lasting capability investment.
First, document the strategic debates. When your team disagrees about how to weight a channel, or how to interpret an audience model, write that down. The disagreement is the learning. It surfaces assumptions your team holds that have never been made explicit.
Second, brief the team that was not in the room. The people who sat through every agency presentation hold knowledge that is invisible to everyone else in the organisation. A structured debrief, not a summary email, transfers that knowledge.
If you are uncertain about who should write the media brief and who should own the debrief after the review, those two questions have the same answer: the people closest to the commercial reality of your media spend, supported by independent expertise that has no interest in the outcome.
Frequently asked questions
What is an agency review? An agency review is a structured process in which an advertiser invites media agencies to compete. The advertiser evaluates the agencies on elements such as; strategic thinking, commercial terms, team capability, and cultural fit before appointing a preferred partner.
What is the value of an agency review beyond selecting a new partner? Beyond vendor selection, a review benchmarks your current media costs against market rates, forces strategic & operational translation of business objectives into media objectives, builds your team’s ability to evaluate agency claims, and surfaces commercial terms your team may not have been exposed to before. That knowledge persists long after the selected agency begins work.
What is the value of reviews in a media context? In a media context, reviews create structured competitive pressure that generates market intelligence your team would not otherwise access. Agencies invest significant resource in proposals, and the thinking they produce, whether or not they win, represents an external audit of your media approach applied directly to your business.
How much is a review worth to an organisation? The direct financial value of a review is typically measured by the improvement in trading terms and media cost benchmarks secured during commercial negotiation. The indirect value, the strategic knowledge, the team development, and the institutional benchmarks established, is harder to quantify but often can be considered substantial.
A well-run agency review is, in the end, a commitment to select the future vendor. However we always recommend embracing the positive side effects.
