Google says it started testing an AI Mode button on the Google Search homepage with Labs users over the past week, replacing the I'm Feeling Lucky button
Google's stalwart search button has a new neighbor: AI Mode. — The artificial intelligence feature is being tested directly beneath …
Context & Ripple Effects
Google had already moved AI Mode from an internal-looking experiment toward a Search feature: it first tested Gemini-powered exploratory queries, then opened an experimental version for complex, multi-part questions to a limited audience. The homepage test is a distribution change, not merely a model-feature update.
By placing the entry point where users begin a search, Google is testing whether AI Mode can become a default navigation choice rather than a destination users must deliberately find. Labs provides a controlled setting for that early-product testing while Google evaluates the placement.
First-order effects
- Labs users see AI Mode directly on the Google Search homepage, with the legacy “I’m Feeling Lucky” position replaced for the test.
- AI Mode gains a more prominent acquisition surface than it had when Google introduced the experimental Search experience for complex questions.
Second-order effects
- The test can reveal whether homepage placement changes the share of queries routed into AI-generated responses versus conventional result pages, informing Google’s wider interface rollout decisions.
- Publishers and other sites dependent on referral traffic have a stronger reason to track AI Mode’s prominence, since a homepage entry point can change how users reach links and answers.
Third-order effects
- If prominent AI entry points persist, web search may be organized increasingly around conversational answer flows, with the traditional results page becoming one option within a broader interface.
- The key competitive advantage shifts toward controlling the default surfaces where AI is invoked—an interface-distribution contest that may intensify pressure on publishers to seek visibility and controls in AI search.
The trend: This is one step in the shift from AI as an optional Search experiment to AI as a first-class entry point in Google’s core discovery interface.
