What should be included in a performance marketing retainer?
A clear retainer should spell out: media management scope and platforms, creative volume per month (concepts, not just ads), testing and reporting cadence, who staffs the account, and what is billed separately (production, spend). If creative volume is not a number in the contract, it is not really committed.
The six things a retainer must name explicitly
- Platforms in scope and those explicitly excluded
- Monthly creative volume: number of net-new concepts and iterations
- Testing cadence and minimum learning review frequency
- Named account team or approval right over staffing changes
- Reporting format, frequency, and data sources used
- What triggers an out-of-scope bill: production, additional platforms, ad hoc analysis
The creative volume clause is the most skipped
Most retainers define media management clearly and leave creative volume vague. "Ongoing creative support" is not a commitment. A monthly number forces both sides to plan and holds the agency accountable to the testing pace that performance compounding requires.
What to check in the reporting clause
Good reporting traces back to a source you can open independently: a warehouse, a verified platform export, or a shared sheet with raw data attached. If reporting is exclusively through the agency own dashboard with no underlying data access, you are dependent on their framing.
Related questions
How often should a performance retainer be reviewed?
Quarterly scope reviews are standard. Monthly check-ins on creative performance and pacing keep the retainer honest between formal reviews.
Should media spend pass through the agency or be direct to platforms?
Direct billing to platforms is cleaner: you own the accounts, see the invoices, and retain data access if the relationship ends. Pass-through billing can obscure the actual spend and rebate arrangements.
