Google Ads Performance Max Optimizer
Get the most out of Performance Max — within its constraints.
Monitor and optimize Performance Max campaigns — limited ad group control, budget adjustments, and asset group performance analysis.
What is Google Ads Performance Max Optimizer?
Google Ads Performance Max Optimizer is an optimization agent that monitors and adjusts Performance Max campaigns using the limited levers available: budget changes, target ROAS, and pause/resume. It enforces a 24-hour cooldown, 15% max change, 14-day learning window, and max 3 actions per run. Built for advertisers running Performance Max campaigns who need disciplined optimization.

The problem — and how this kit solves it.
The Problem
Performance Max campaigns offer fewer optimization levers than Search or Display. You can adjust budget and target ROAS, but not keywords, placements, or individual bids. Most teams either over-adjust (breaking the algorithm's learning) or under-adjust (wasting budget on poor performance).
The Solution
The agent monitors PMax campaigns every 4 hours, evaluating performance against a target ROAS of 2.0 over a 7-day window. It proposes budget adjustments (max 15% change), target ROAS changes, and pause/resume actions. A 14-day learning window prevents disrupting the PMax algorithm. Max 3 actions per run with 24-hour cooldown between actions.
The Outcome
Optimize Performance Max ROAS with disciplined adjustments that respect PMax's 14-day learning cycle.

Who is this for?
Retailer running PMax as primary campaign type
The optimizer ensures PMax budgets scale with performance. When ROAS exceeds target, it proposes budget increases. When ROAS drops, it proposes decreases — all within the 15% guardrail.
Team transitioning from Search to PMax
The 14-day learning window and 24-hour cooldown prevent the common mistake of over-adjusting PMax campaigns that need time to learn.
Frequently asked questions
Performance Max campaigns require longer learning periods than Search or Display campaigns. Google recommends waiting at least 2 weeks before evaluating PMax changes. The 14-day window prevents disrupting the algorithm.
Three actions: campaign pause/resume, set budget (max 15% change), and set target ROAS. PMax does not expose keyword, placement, or bid modifier controls, so the optimizer works within these constraints.
Yes. The agent performs asset group analysis as part of its monitoring, surfacing performance insights. However, asset group changes are informational only — PMax does not expose programmatic asset group editing.
PMax campaigns are sensitive to concurrent changes. Limiting to 3 actions per run combined with 24-hour cooldown ensures each change has time to take effect before the next one.
