Why it matters
Performance Max (PMax) is where Google is steering most advertisers. Instead of building separate Search, Display and YouTube campaigns, you give one campaign your goal, a budget, creative assets and optional audience signals. Google's AI then picks the channel, audience and bid for each auction, as set out in Google's overview. For a retailer with a product feed, it can be strong. For a business with little conversion data, it can spend freely and learn little.
The catch is visibility. You see results, but you control fewer levers than in a Search campaign, so the quality of what you feed it decides the outcome.
How to get it right
- Define the conversion properly. If the goal counts every form view or button click, PMax will optimise for the cheapest of them. Count qualified leads or purchases, ideally with enhanced conversions and offline data from your CRM.
- Give it good assets. Several images, short videos and varied headlines per asset group, organised by product or service, not one catch-all group.
- Use audience signals as hints. Your customer lists and remarketing data point it in the right direction; they are not hard limits.
- Exclude your brand if you want new customers. Brand exclusions and a check of the search terms categories show how much is brand demand you would have won anyway.
- Give it time and a steady budget. Judge it over weeks, not days.
Common mistakes
- Reading the platform ROAS as truth. It may include returning customers and brand searches.
- Launching with thin tracking.
- Making it the only campaign, with no Search campaign to protect the keywords that matter.
