Summary
Google has published a four-article Rethink 2026 collection for marketers preparing for an AI-powered holiday shopping season. The collection covers agentic commerce, measurement, YouTube Demand Gen and AI Max for Search campaigns.
Google has published Rethink 2026, a four-article collection focused on product updates and practical guidance for marketers preparing for what it describes as an AI-powered holiday season.
The collection, published on September 16, 2026, is part of Google’s Ads & Commerce Blog. Google says the material is intended to help businesses engage customers and improve return on investment during the holiday period.
Four areas covered by the collection
The first article focuses on agentic commerce, along with product-feed practices intended to help businesses promote holiday offers. In this context, agentic commerce refers to shopping experiences in which software agents can assist with product discovery or purchasing tasks. The collection page does not provide the technical specifications of the listed updates, directing readers to the individual article for those details.
A second article covers new data and measurement capabilities. Google presents these tools as a way for marketers to make faster decisions about campaign performance and business growth.
The third entry describes an August update to Demand Gen, Google’s campaign format for reaching audiences through visual and video advertising, including on YouTube. The update includes new messaging, travel and creative features. Google positions these capabilities as tools for generating leads and acquiring customers.
The fourth article addresses AI Max for Search campaigns. The listed additions include A/B testing tools and performance planners for changes involving campaign budgets and bidding. These features are presented as ways to plan and evaluate Search campaign adjustments.
Why the collection matters
Taken together, the four topics cover several stages of digital advertising: product discovery and feeds, campaign measurement, audience and creative development, and automated Search campaign planning. Rather than announcing one standalone product, the collection brings several updates into a single programme aimed at holiday marketers.
The emphasis on testing, measurement and planning also reflects a practical shift in how automated advertising systems are managed. Campaign automation can determine more of the delivery and bidding process, while marketers increasingly need tools for comparing changes, allocating budgets and assessing outcomes.
Google’s page provides the high-level scope of the four articles. The individual posts are the source for the operational details of each update.
