Define the placements you need to distinguish
List the websites, channels, applications or campaign groups you want to compare. Decide what a source label represents and keep that meaning consistent. A label that combines a country, placement and creative can become difficult to interpret if those components change together. Use a simple naming plan and ask which identifiers the programme can actually accept and show in reports.
Agree the supported measurement route
Explain whether you need a basic affiliate link, a promo-code placement or integration with an existing tracker. If you need a postback, ask which events, identifiers and test procedure are supported for your account. Do not assume that a parameter or event name used by another advertiser is valid here. Confirm the reporting period and any expected processing delay before evaluating a test.
Keep evidence from a small test
- The source and placement identifier.
- The issued link and intended destination.
- The device and time of the test.
- The steps actually completed.
- The corresponding report or an unresolved observation.
For example, check one website placement and one channel placement separately rather than changing both during the same test. If an event is absent, describe what you observed instead of immediately attributing the cause to the tracker. Use the agreed test method, and ask Ilya to clarify any account-specific uncertainty before increasing spend.
