PPC Without Performance Max
Performance Max is Google's most profitable product. For Google. For advertisers it often means paying more for less. Here is why, and what a better approach looks like.
Why pMAX hurts your bottom line
You do not know where your money goes
Performance Max decides everything: placements, audiences, search terms. You see the total spend and a ROAS number. You do not see the decisions behind them.
When results drop, you cannot diagnose why. You are flying blind.
📦 How pMAX reports
You see: total spend, total conversions, ROAS. You don't see: which keywords triggered, which placements consumed most spend, why any decision was made.
Someone searches "[YourBrandName]" on Google. They would have navigated to you anyway. pMAX shows an ad. They click. Google counts a conversion. You pay €0.50–€3.00 for a click that would have been free.
You pay for customers who would have come anyway
pMAX automatically targets people searching for your brand name. Customers who would have visited your site organically anyway. The system shows them an ad, they click, and Google credits the conversion to pMAX.
The result: inflated ROAS numbers, padded conversion counts and money spent on traffic you already owned.
Optimising for the wrong metric
pMAX optimises on revenue. It loves high-ticket items even when their margin is tiny. It ignores profitable products with lower prices. You end up spending on what looks good on paper, not what actually earns.
Profit-based bidding solves this directly: each product bids according to its actual net margin.
