Google Ads is testing a button that lets advertisers apply a seasonal theme directly inside a Performance Max asset group. Marketer Thomas Eccel spotted the option, labeled “Apply theme to asset group,” and posted it on LinkedIn. Search Engine Roundtable’s Barry Schwartz noted he had seen references to the feature as early as April, which suggests the rollout is still gradual rather than complete.
Performance Max, Google’s automated campaign type spanning Search, YouTube, Gmail and Display, runs on asset groups. Those groups bundle headlines, videos, images, logos, sitelinks, descriptions and audience signals that Google reassembles for each channel. Seasonal creative has always meant rebuilding those bundles by hand. Each holiday or sale window meant new images, new copy and new audience signals, assembled from scratch.
The new option shortcuts that process. Advertisers pick a theme, among them Mother’s Day, Valentine’s Day, Black Friday, a back-to-school push, Christmas and a summer sale, and Google’s AI assembles assets to match the moment. The pitch is simple: skip the manual rebuild.
Eccel’s own advice, per Search Engine Roundtable, is to treat the tool as a sandbox rather than a shortcut to publish. A holiday theme still has to match a specific brand’s voice, offer and inventory, and he said he would use the generated output as inspiration rather than apply it directly to a live account.
That caution points to the real tradeoff. Auto-generated seasonal creative saves the setup time that keeps many advertisers from running timely promotions at all. It also hands more creative judgment to a system optimized for engagement patterns, not brand consistency, which is exactly the failure mode Eccel is flagging. Google has not published performance data comparing theme-assisted asset groups against manually built ones, leaving advertisers to test the feature blind on both quality and results.
The button fits a broader pattern at Google Ads, where Performance Max has steadily absorbed tasks that used to require a human draft: automatically generated headlines, AI-created images and now seasonal creative kits. Each addition trades advertiser control for setup speed. None of them come with a review step Google actually enforces.
Advertisers who turn on the theme option should treat every generated asset group as a draft, not a launch. Check headlines against the actual promotion terms, confirm images match current inventory, and run the seasonal group against a manually built control before shifting budget. Teams planning Black Friday or holiday campaigns in the next ninety days should test the feature now, while the rollout is still limited, rather than during peak season when a brand mismatch costs the most to fix.
Search Engine Roundtable’s Barry Schwartz reported on the Performance Max “Apply theme to asset group” option on July 7, 2026, citing a LinkedIn post from Thomas Eccel.
