How should an agency handle a request for guaranteed organic views?

Distinguish the work you can commit to from the audience response you cannot directly control. Describe the deliverable, quality checks, reporting and remedy for operational mistakes under the actual agreement. Do not turn a target into a guarantee because the sales conversation needs a neat number.

If the client requires a different risk arrangement, escalate that commercial decision explicitly. The proposal should make the boundary understandable before payment, not rely on a footnote to contradict the headline.
