Google adds seasonal creative theming to PMax asset groups

Refreshing creatives for every seasonal moment just got significantly faster — Google has quietly launched Asset Group Theming inside Performance Max, letting advertisers apply seasonal themes to existing asset groups without rebuilding from scratch.

How it works. Advertisers can clone a high-performing asset group and apply a theme — Google then generates themed image variations and suggests aligned headlines and descriptions, while leaving the original asset group completely untouched for safe testing.

Available themes cover.

• Promotional: Sale, Studio/Editorial
• Seasons: Winter, Spring, Summer, Fall
• Cultural moments: Christmas, Black Friday/Cyber Monday, Halloween, Valentine’s Day, Easter, Mother’s Day, Father’s Day, Hanukkah, New Year, Lunar New Year, and Back to School

Where to find it. Look for the prompt inside Asset Groups ahead of major holidays, or via “Apply theme to existing asset group” when creating a new one.

Important caveat. This is a starting point, not a finished product. The tool uses existing images as a base and adds themed backgrounds — it does not replace videos, and typically only updates a handful of headlines to match the theme. Everything still needs to be reviewed and sense-checked before going live.

Why we care. Seasonal creative refresh has always been one of the more time-consuming parts of campaign management — requiring design resources, rebuilding asset groups, and risking performance drops on proven setups. This feature removes most of that friction, letting teams adapt their best performers to key moments in minutes rather than days.

The bottom line. Think of it as a creative assistant, not a replacement for a designer — but for advertisers managing multiple seasonal peaks across the year, the time savings alone make it worth exploring.
