What buyers actually pay for
Paid media agency fees pay for the work of planning, running and improving advertising campaigns. They do not automatically include the money paid to advertising platforms or publishers.
A useful proposal separates management, media buying, creative production, measurement and technology. Without that separation, a low management fee can conceal a narrower service, while a higher fee may include work another bidder prices separately.
There is no useful universal price without a defined scope. Before asking agencies to quote, specify your channels, markets, objectives, account condition and creative requirements. Use the paid media agency directory to identify candidates, then give each the same brief.
How paid media agency fee models work
Fixed retainer
A retainer charges an agreed amount for recurring services. It can suit buyers who want predictable management costs and a defined working relationship.
The important question is what changes the price. Additional markets, channels, accounts, reporting requirements or creative work may trigger a revised scope even when the advertising budget stays unchanged.
Ask for the deliverables, exclusions and change-control process in writing. A fixed fee is not necessarily an unlimited service.
Percentage of advertising spend
Under this model, the management charge changes with the advertising budget. The agreement needs to define the spending base precisely.
Check whether the percentage applies to:
- Platform spend before or after credits and refunds.
- Media alone or media plus technology and third-party costs.
- All accounts or only those the agency actively manages.
- Committed budgets or actual invoiced expenditure.
Also ask about minimum charges, spending bands and caps. Budget growth does not necessarily create proportionate management work, so understand what additional service accompanies a higher fee.
Hourly and project fees
Hourly billing can suit advisory work or an uncertain workload, provided there is an estimate, approval threshold and clear record of activity.
Project pricing can make audits, tracking repairs, account restructures and launch work easier to commission. Confirm acceptance criteria and whether implementation is included. An audit that identifies problems is different from a project that fixes them.
Performance-based and hybrid fees
Performance compensation links some payment to an agreed outcome. A hybrid may combine a base retainer with spend-based charges or an incentive.
Define the outcome before discussing the reward. Revenue, qualified leads and new customers are different measures. The contract should address attribution, returns, cancellations, duplicate leads, existing customers and the source of truth.
Performance pricing does not eliminate risk. It redistributes it, and can create incentives to favour easy-to-attribute conversions over harder growth work.
Why channel scope matters more than a market average
Paid media covers distinct buying environments, not a single interchangeable service. For context, the IAB Internet Advertising Revenue Report for full-year 2023 reported US search advertising revenue of **$88.8 billion**, display revenue of **$66.1 billion**, and digital video revenue of **$52.1 billion**.
These are historical advertising-market revenues, not agency fees or recommended budget allocations. They should not be used to calculate a management charge.
The practical comparison is operational: search management may involve queries, feeds and landing-page relevance; video work may require production, adaptation and placement controls. Ask bidders to price your actual channel requirements rather than applying a market statistic to your budget.
What should be included in the scope?
Request an inclusion-and-exclusion schedule rather than accepting “full-service management” as a description.
Strategy and account operations
Establish who handles research, channel planning, account setup, campaign builds, budget pacing, optimisation and testing. Ask who does the work, who supervises it and how cover works during absences.
Separate recurring work from onboarding. An inherited account with unreliable conversion tracking may need remediation before routine optimisation is useful.
Creative and landing pages
Clarify whether the fee includes copy, design, editing, resizing and revisions—or only uploading assets you supply. Specify how creative demand will be planned and approved.
Landing-page recommendations are not the same as design, development and testing. If website changes are needed, decide whether the paid media agency, your internal team or a conversion optimisation specialist owns implementation.
Measurement, reporting and technology
Ask whether tracking implementation, analytics configuration, dashboard subscriptions, call tracking and product-feed tools are included or separately billed.
Reporting should identify decisions and next actions, not merely reproduce platform dashboards. Agree which system governs business outcomes and how discrepancies will be investigated.
For creative approval, allocate responsibility for claims and disclosures. The FTC’s advertising and marketing guidance is a useful reference for US campaigns. Agency review should not be treated as a substitute for any legal review your business requires.
How to normalise competing proposals
Give every bidder the same assumptions
Specify channels, markets, objectives, campaign requirements, reporting expectations and creative responsibilities. State what your business supplies, including assets, product feeds, landing pages and analytics access.
Ask each agency to distinguish its recommended scope from the scope requested. Otherwise, you may accidentally compare different strategies rather than different prices.
Build a common cost schedule
Organise each proposal under the same headings:
- **Media:** money paid to platforms and publishers.
- **Management:** retainers, spend-based charges and minimums.
- **Setup:** audits, migrations, builds and tracking remediation.
- **Production:** creative, localisation and landing-page work.
- **Technology:** subscriptions, data and measurement tools.
- **Variable charges:** incentives, out-of-scope work and pass-through costs.
Compare the same contract period and currency, treating taxes consistently. Show onboarding separately, but include it in the commitment-period total. Keep refundable deposits distinct from fees.
Mark unspecified costs as unresolved, not included. A blank proposal line is not evidence that the service is free.
Test the price under changing conditions
Ask bidders to recalculate their charges for your base plan, a lower-spend period and an expansion scenario. Use your own approved planning assumptions rather than generic examples.
Check what happens when campaigns pause, a channel is added, creative requirements increase or results miss target. The cheapest starting quote may not remain cheapest under the conditions you actually expect.

Contract details that protect the comparison
Before signing, confirm:
- **Billing transparency:** who invoices media and whether third-party costs carry a markup.
- **Commercial interests:** how rebates, credits, commissions and other benefits are disclosed and treated.
- **Ownership:** your rights to accounts, audiences, creative, tracking and historical data.
- **Approvals:** who can change budgets or commission additional work.
- **Exit terms:** notice, termination charges, asset delivery and handover support.
Where practical, retain administrative control of advertising and analytics accounts. Ask what access and exports you will receive if direct ownership is not possible.
Choose the clearest value, not the smallest fee
A strong proposal connects price to identifiable work, responsible people and an agreed measurement approach. It also makes exclusions and commercial incentives easy to understand.
