Asset Groups (Performance Max)

Performance Max replaces the old structure of ad groups and individual ads with asset groups. Each asset group holds all the raw material Google needs to build ads automatically: multiple headlines and descriptions, several images in different aspect ratios, your logos and ideally one or more videos. You also attach an audience signal, which is a hint about who is likely to convert, and for retail campaigns you can link product groups from your Merchant Center feed. Google then assembles ads on the fly to fit each placement and surface.

The smart way to use asset groups is one group per distinct theme, product line, audience or message, rather than dumping everything into a single group. Splitting by theme gives you cleaner reporting, lets you tailor creative to each segment and helps you see which themes actually drive results, since Performance Max reporting at the asset group level is limited. Strong, varied, on-brand assets in each group are what give Google's algorithm enough material to find winning combinations instead of repeating a few weak ones.

Inside a Performance Max campaign you create one or more asset groups, each with a theme. You fill each group with text assets, images in horizontal, square and vertical ratios, logos and videos, and you add an audience signal to steer the algorithm. For e-commerce, you also assign product listing groups. Google then combines these assets dynamically, tests countless permutations across every Google surface and shifts spend toward the combinations and placements that hit your conversion or value goal.

Asset groups are where you exert most of your control in an otherwise automated campaign type. Because Performance Max decides placements and bids for you, the quality and structure of your asset groups is the main lever you have left to influence results. Thoughtful theming improves the limited reporting you get, prevents unrelated products from competing for the same generic creative, and gives the algorithm rich, relevant material, which directly affects whether the campaign finds profitable demand or burns budget on weak combinations.
