The Performance Max versus separate campaigns debate has settled into a clear answer for mature accounts. Run both. PMax gives reach and automation, dedicated Search and Shopping give control and visibility. The teams winning in 2026 stopped picking a side and started using each for what it does best.
Performance Max is not a replacement for control. It is a way to cover everything you are not actively managing.
The long-running argument over whether Performance Max beats running separate Search and Shopping campaigns has reached a settled answer for most mature accounts. Run both. The teams getting the best results in 2026 stopped treating it as a choice and started using each campaign type for what it actually does well.
The trade-off is straightforward. Performance Max gives you broad reach and automated discovery across Search, Shopping, Display, YouTube and Gmail with very little manual work. Dedicated Search and Shopping campaigns give you control and visibility, the ability to see which queries trigger your ads and to bid at the product and keyword level. One optimises for coverage. The other optimises for precision.
PMax also has known blind spots. You cannot see with any precision which search queries are triggering your Shopping ads. New products struggle to get impressions because the algorithm has no history to work with, while best sellers hog the budget. Left alone, it quietly defaults to harvesting demand you already had.
The pattern that works pairs the two. Keep dedicated Search campaigns for your highest-value and brand-specific keywords, where exact-match control matters. Use Performance Max to cover everything else. For ecommerce, many advertisers now run Standard Shopping alongside PMax specifically to claw back the query visibility PMax hides.
Why it matters
For Australian advertisers with limited budgets, the all-in-on-PMax approach is tempting because it is easy. The risk is handing your spend to a black box that protects your branded and best-selling terms while telling you nothing about why. You end up paying a premium to win sales you would have won anyway, with no data to argue otherwise.
The threshold worth remembering. If a campaign drives 30 or more conversions a month, it is worth the effort to compare both structures properly rather than guessing.

What to do about it
The answer to almost every Performance Max question in 2026 is not which one. It is how you combine them, and how much control you are willing to trade for reach.
