Agency backfill · White label
We run the accounts agencies put their name on.
A share of Channelshift’s work is managed behind agencies: their clients, their reporting relationship, and our paid-media execution underneath.
The context
Capacity changes. The client relationship does not have to.
Agency demand rarely arrives in a smooth line. A new account can exceed the capacity of the available team. An existing client can add a platform that needs more specialist attention. A complicated account can require an operator who can enter the work without changing who owns the relationship.
That is the role of agency backfill. Channelshift manages the agreed paid-media work on behalf of the agency. The agency remains the client-facing partner and puts its name on the reporting. Channelshift’s role is execution underneath.
The arrangement works because we are not competing for the relationship. We are buying the media.
Why agencies call
Backfill starts with a specific constraint.
The public engagement describes three reasons agencies bring Channelshift into their accounts:
The work outgrows in-house capacity
The agency needs additional delivery without moving the account away from the existing client relationship.
A client requires a specialist
The scope or platform calls for focused media-buying experience that is not currently available inside the agency.
Someone must step in without disruption
The account needs management, but the agency does not want the operating change to become a client-facing change.
Those triggers describe the role. They do not assume a fixed engagement size, team structure, or commercial arrangement. Those details depend on the agency and account.
The media remit
Cross-channel execution, kept behind the agency brand.
Google Search
Search campaign management within the agency’s client strategy and reporting structure.
Google Shopping
Commerce demand capture alongside the wider Google Ads account.
Performance Max
PMAX management as part of the documented Google Ads remit.
Meta
Paid social execution where Meta sits inside the agency’s account scope.
Demand Gen
Google Demand Gen delivery within the cross-channel engagement.
YouTube
Video media buying managed behind the agency relationship.
Evidence boundary
What the $2.2M figure does—and does not—say.
The source case records $2.2M as media managed. That is the only quantitative claim attached to this agency-backfill engagement.
No currency, time period, number of accounts, or performance outcome is specified. The figure should therefore be read as an indicator of media-management scope, not as a return, savings, growth, or efficiency claim.
The remaining evidence is operational: the work is performed on behalf of agencies, the agency remains at the center of the client relationship, and the documented remit spans six paid-media channels.
Evidence source: the agency-backfill engagement published in Channelshift’s case-study collection. Agency and client names are withheld.
The decision
Judge the model before handing over an account.
An agency evaluating backfill should establish how access, measurement, communication, approvals, reporting, quality control, and handoff will work. These questions matter because the agency must be able to explain and stand behind the work even when another operator performs it.
Our guide to evaluating a white-label PPC partner provides a diligence framework. The white-label PPC service page explains how Channelshift fits within that model, and the services hub shows the related audit and measurement work.
