A global media agency review is not a national pitch multiplied by the number of markets on your roster. It is an architecture question: two structural decisions shape the entire process before a single brief is written. The first is the route through which you select. The second is how you keep outcomes comparable across markets that differ commercially, legally, and in media structure.
If you are managing a selection across ten or twenty countries, those two decisions deserve serious attention.
Why multi-market selections fail without a clear structure
A global selection that begins without resolving its architecture tends to produce one of two failure modes. Either the process collapses into a country-by-country exercise with no shared frame, leaving you with incomparable outcomes and a weakened commercial position. Or it overcentralises, selecting a network on headquarters credentials while the teams who will actually plan and buy in each market go unscrutinised.
Neither outcome serves the advertiser. The first leaves you with twenty independent decisions that cannot be consolidated into a negotiating position. The second gives you a name on a contract and an unknown team behind it.
The process architecture exists to prevent both. The choice of model, global, regional, or local, is a prior decision that this process assumes you have already made. If you are still working through that question, the comparison of international media agency structures covers it in detail.
The two routes a global media agency review can take
There is no single correct way to structure a multi-market selection. There are two main routes, and the right one depends on how your business is built geographically and commercially.
Route one: key markets first. A basket of your most strategically important markets runs a full pitch. How many markets belong in that basket depends entirely on where your business weight sits, it is not a fixed number. The agencies that win those markets become the field from which remaining countries choose, each with its own local round. The logic is that the key markets set both the strategic standard and the commercial reference point for the rest of the portfolio.
Route two: network first. Two or three networks are evaluated centrally against network-level strategic and commercial criteria: their global proposition, data and technology infrastructure, and the terms they are willing to discuss at a multi-market level. Their local agencies then pitch per market for the individual country business. The frame is set at the centre; the local rounds decide who wins each market.
In both routes, a local pitch round is not optional and should not be treated as a formality. A network credential tells you almost nothing about the team that will run the business in a specific market. Their depth in local media planning, their relationships with local media owners, and their knowledge of trading conditions, which differ fundamentally between markets, only become visible in a local round. The local pitch is how the process stays close to the principle that the best agency operates at the level where media is actually planned and bought.
Comparability: the craft that holds the process together
One selection across many markets stands or falls with the ability to compare outcomes. This is harder than it sounds.
Currency differences are the visible challenge. Trading customs are the less visible one. What “gross” and “net” mean in a media context differs between markets. In some, gross rates and agency commission structures are standard; in others, net buying with transparent fees is the norm. A financial response that asks the same question in the same format will receive answers that measure different things unless the format itself accounts for this.
Identical response formats across all markets, including the financial chapters, are the technical requirement. The craft of that format belongs to the evaluation stage, and the mechanics of scoring and comparing responses across markets is covered in the article on agency selection criteria.
The same comparability logic applies to the brief. Errors in a multi-market brief do not stay contained. They multiply across every market running in parallel. A brief that is ambiguous on scope, or that leaves the financial chapter open to local interpretation, produces incomparable responses at exactly the moment you most need to compare them.
What the process asks of the advertiser
A well-structured multi-market selection is manageable when properly guided, but it requires two things on the advertiser side that are genuinely non-negotiable.
The first is a small central team with the authority to decide. A selection that involves regional leads who can obstruct or delay central decisions, or that has no single owner for the commercial outcome, tends to produce compromised results. The central team does not need to be large. It needs to have a mandate.
The second is discipline on the brief. This is related but distinct. The brief sets the frame for every market running in parallel. Changing it mid-process, or allowing local markets to reinterpret it independently, breaks the comparability that the entire architecture is designed to protect.
There is a third requirement, and in practice it decides whether the appointment holds. Local markets do not make the central decision, but they have to be genuinely involved in it. For local media, the daily working relationship happens there: the planning, the buying, the weekly contact. A team that was never asked, and that ends up with an agency it did not want, is unlikely to make that relationship work - and no central mandate compensates for that. Involving the markets is not a courtesy to keep the peace. It is what makes the outcome successful once the process is over. The distinction to set out at the start is simple: the centre decides, the markets are heard & involved, and both parts are real.
A well-run multi-market process typically runs three to eight months from first brief to appointment, depending on the number of markets and the complexity of the footprint, with the agency transition adding further time after that. These are realistic planning bands from experience, not a guarantee. Every engagement is scoped individually. A longer runway almost always produces a better result, particularly in the commercial negotiation phase, where the more time you allow, the stronger your negotiating position.
In one engagement spanning ten geographies, the cumulative improvement came to roughly 15 to 20 percent across the total media investment. That figure reflects a well-structured process with genuine comparability across markets. It is not a baseline expectation for every engagement.
For a full picture of how a multi-market selection is structured and what drives value across markets, the review of multi-market media agency selection covers the complete framework. Organisations that want to understand where value leaks between global deals and local buying will find the analysis of global vs local media buying directly relevant to what a structured process is designed to protect against.
Understanding the local media environment in each market you are selecting for also matters. Media structures vary considerably. The landscape in Southeast Asia, for example, differs substantially from European or North American norms in terms of inventory, trading relationships, and measurement infrastructure.

Frequently asked questions
What is a global media agency review? A global media agency review is a structured selection process through which an advertiser evaluates and appoints media agencies across multiple markets simultaneously. Unlike a single-country pitch, it requires a shared process architecture to keep outcomes comparable and to consolidate the advertiser’s commercial position across markets.
Should every market run its own pitch in a global selection? A local round belongs in every serious multi-market process, whichever route is chosen. A network credential reveals little about the specific team that will plan and buy media in a given country. The local round is how you evaluate planning depth, local media relationships, and market-specific trading knowledge, while keeping outcomes comparable through a frame set centrally.
What are the two main routes for structuring a multi-market agency selection? The first route runs a full pitch in the most strategically important markets first; the winning agencies’ networks form the field for remaining markets. The second selects two or three networks centrally on strategic and commercial criteria, then runs local pitches within each network. The right route depends on where business weight sits geographically and how the advertiser is structured.
How long does a multi-market media agency selection take? A well-structured multi-market selection typically runs three to eight months from first brief to appointment, depending on how many markets are involved. Agency transition adds further time after appointment. A longer runway almost always strengthens the advertiser’s commercial negotiating position.
What is the biggest risk in a multi-market selection process? Local teams that do not support the outcome. Whatever is planned and bought in the market itself depends on that relationship working, so a market that ends up with an agency it was never asked about tends to underperform there - and that shows up months after the process closed, when nobody is looking at it anymore. The second risk is comparability failure: if markets interpret the brief differently, use different financial definitions, or respond in incompatible formats, the advertiser loses the ability to consolidate its position into a coherent commercial negotiation. The first risk costs you the result. The second costs you the best version of it.
