For over fifteen years, digital marketers have written premature obituaries for the humble keyword. Yet, search marketing has relied heavily on them—until now. Following announcements at Google Marketing Live (GML), the shift from keywords to user-driven prompts is officially happening. Consumers are changing how they search, and Google is responding with AI Brief, a Gemini-powered control layer in Google Ads which is designed to replace traditional keyword targeting with natural language steering.
The Demand-Side Shift
Keywords are not disappearing because Google took them away; they are fading because users stopped using them. With Google’s redesigned search box dynamically expanding to invite complex, conversational questions, “AI Mode” has surpassed 1 billion monthly users. Queries in this mode are now three times longer than traditional searches. Search advertisers can no longer capture a full paragraph of a user’s intent using a restrictive list of broad, phrase, or exact match types.
Within Google Ads, the option to use AI Max with conversion focused search campaigns has been available for the past year, and although this has shown mixed quality results to date, this is the future direction that Google is taking.
AI Brief will roll out in English for AI Max for Search campaigns over the coming months, followed by Performance Max and AI Max for Shopping campaigns. When users start using AI Brief, the existing text guidelines provided as part of this tool will automatically move to messaging guidelines within AI Brief.
What is AI Brief?
Instead of managing static lists of keywords, Google Ads advertisers using AI Brief negotiate with AI Max using structured guidelines:
* Messaging guidelines to dictate what the brand voice should say.
* Matching guidelines to detail which search concepts to target or avoid.
* Audience guidelines to pinpoint specific customer segments.
This turns campaign management into a dynamic consultation. Advertisers define the “why” and “what,” while Gemini generates the necessary assets and continuously maps target intent.
The New Search Funnel
Short, high-intent keywords will still hold a job at the very bottom of the funnel for quick, transactional purchases (e.g., “newborn photographer Sydney”). However, AI prompts will now dominate the discovery and research phases. Brands that ignore conversational AI Brief targeting risk missing out on the consideration mix entirely before a buyer ever reaches that final transactional search.
This is a developing system however, and requires considered advertiser input as well as reliance on the Google system working effectively. It will improve in time although early signals related to search performance and relevancy have been poor, but it is certainly something that advertisers should consider testing.
The future of advertising requires coexisting with automation rather than escaping it. By adopting AI Brief, marketers can shift away from manual keyword spreadsheet management and focus on the strategic goals that truly scale revenue.
