You might have seen it when creating a new asset group or wondered what it does.
This feature lets you add seasonal or holiday themes to your asset groups without rebuilding everything from scratch. Instead of manually creating new headlines, descriptions, and images for Black Friday or Christmas, you select a theme and Google’s AI helps generate assets that match the moment.
What Is the Apply Theme to Asset Group Feature?
The Google Ads Apply theme to asset group option appears in your asset group creation menu. It works with Performance Max campaigns, where your ads run across YouTube, Gmail, Search, Display, and other Google channels.
Asset groups contain your marketing materials: images, logos, headlines, descriptions, videos, sitelinks, and audience signals. Google automatically mixes and matches these assets based on which channel your ad appears on.
When you select a theme, Google uses your existing images as a base and adds themed backgrounds or seasonal elements. The system also suggests headlines and descriptions that align with the chosen theme.
Which Themes Can You Apply to Your Asset Groups?
Google offers themes for promotional events, seasons, and cultural moments. The available themes include:
- Promotional events like Sales and Studio
- Seasons including Winter, Spring, Summer, and Fall
- Holidays such as Christmas, Halloween, Valentine’s Day, Easter, and Hanukkah
- Cultural events like Black Friday, Back to School, Mother’s Day, and Lunar New Year
The feature has been rolling out gradually since April 2026. Not every account has access yet. You might see the prompt before major holidays or when creating a new asset group through the “Apply theme to existing asset group” option.
How Does Theme Application Work in Practice?
Google doesn’t generate entirely new visual content. The system takes your existing images and adds themed backgrounds or seasonal elements. Your videos remain unchanged.
The AI suggests themed headlines and descriptions based on the holiday or season you select. These suggestions aim to match the cultural moment while staying connected to your products or services.
Thomas Eccel, who shared screenshots of the feature on LinkedIn, noted that themes center around “seasons, cultural moments and holidays.” Instead of building a seasonal asset group from scratch every time, you apply a theme and Google helps you create assets that fit the moment.
Should You Let Themed Asset Groups Run Automatically?
Thomas Eccel offered clear advice: “Use them to play around with, but do not let it run on autopilot.”
A holiday theme still needs to match your brand and your offer. The Google Ads Apply theme to asset group feature provides a starting point, not a finished solution.
You should review every themed asset before publishing. Check that the headlines make sense for your products. Verify that the image modifications align with your brand guidelines. Confirm that the descriptions accurately represent what you sell.
Google’s AI works fast, but speed means nothing if your themed assets confuse customers or misrepresent your business.
While Google’s new theme application feature helps structure your seasonal campaigns, you still need compelling, on-brand copy for your headlines, descriptions, and ad variations. Creating multiple variations for A/B testing takes time, especially when you’re managing seasonal campaigns across different holidays and events.
