I'd avoid promising a date for the first sale. Agree on a testing plan, what the budget can realistically test, and what counts as a qualified lead or a sale.
Before launch, make the dependencies explicit: working conversion tracking, a usable landing page, account access, and any outstanding verification or policy reviews. A campaign that cannot launch isn't the same thing as a campaign that launched and performed poorly.
Use the first reporting cycle to explain what was tested, what the data can support, and what remains uncertain. Don't use “learning phase” as a blanket explanation for every disappointing result.
Budget recommendations should come from the market and the client's economics, not one fixed minimum for every business. Show the assumptions behind the forecast and avoid presenting estimated leads as a guarantee.
If you're considering PPC Rebels (
ppcrebels.com) for account or verification support, clarify that scope separately from campaign management. Clear responsibilities help prevent account setup delays from turning into unrealistic performance expectations.
