Warn advertisers of weak budgets before they pause in week two

You’re the ai / ml engineer. Your team is in the room. Printed Oct 15, 2026.

Performance+ asks automatic bidding to learn before many campaigns have enough signal.

Low entry budgets make experimentation accessible, while adequate event volume makes automatic bidding dependable.

Who you’d be doing this for

“I started at a test budget, then spent a week guessing whether the campaign needed more time or more money.”

Laura Vazquez · Paid Media Manager

Sets first budgets and ROAS goals for a direct-to-consumer retailer using Performance+.

What is at stake

Thirty-eight percent of new Performance+ campaigns start below 10 weekly optimization events and often pause before week two. You must weigh a useful early budget recommendation against overclaiming what historical delivery can predict for a new campaign.

Why it isn’t already fixed

Every obvious fix costs something else. That’s the part you’d have to decide.

  • low test budgets vs. sufficient learning signal
  • helpful guidance vs. false certainty
  • offline calibration vs. live customer behavior
  • setup simplicity vs. informed budgeting

Why Pinterest

Performance+ unifies bidding for advertisers who increasingly need measurable outcomes from early campaign spend.
