Maximising Ad Spend in Google Performance Max (PMax) - Key Questions and Answers

What is the best way to maximise ad spend in Google Performance Max?

The most effective way to increase spend in PMax is to combine higher budgets, flexible bidding, and broad targeting. Give Google’s AI room to scale by removing unnecessary limits and feeding it diverse, high-quality creative assets.

How do I increase my campaign budget in PMax?

Go to your campaign settings and raise your daily or monthly budget. PMax automatically reallocates this across Search, YouTube, Display, Discovery, and other Google channels to maximise conversions or conversion value.

Which bidding strategy should I use to drive more spend?

Use Maximise Conversions or Maximise Conversion Value. Avoid setting restrictive target CPA or ROAS limits when scaling — this allows Google’s algorithm to bid more freely and spend the budget efficiently.

How does expanding targeting help increase ad spend?

Adding more locations, languages, and audience signals increases your eligible reach. The wider your audience, the more opportunities PMax has to spend your budget and find profitable conversions.

Why are creative assets important for scaling PMax?

PMax uses your creative mix to match users across all Google channels. Upload multiple images, videos, headlines, and descriptions so ads can appear in more formats and placements, unlocking new spend potential.

Should I remove exclusions from my campaign?

Yes, review and reduce exclusions such as negative keywords, product disapprovals, or audience restrictions. Keep only those that protect profitability or brand safety. Too many exclusions restrict spend and limit discovery.

What is the new customer acquisition setting in PMax?

It’s a bidding option that allows Google to bid more aggressively for new customers while maintaining efficiency for existing ones. Enabling this feature helps increase spend and attract valuable first-time buyers.

How often should I optimise my PMax campaign?

Check performance weekly but avoid daily changes. PMax needs time to learn and stabilise after adjustments. Use Google’s insights to identify underperforming asset groups or product feeds and reallocate budget strategically.

Why should I allow a learning period after making changes?

Each time you update your budget, targeting, or bidding, PMax restarts its learning phase. Frequent edits reset optimisation progress. Give it time to gather data so the algorithm can accurately adjust bids and placements.

What’s the key takeaway for maximising ad spend in PMax?
