For marketers, this means search behavior, campaign management, and content discoverability are fundamentally changing because users are increasingly acting through AI agents rather than directly on websites.

There is no official date yet. Google is rolling out new features like AI Mode in the US first. Experience from past rollouts shows that European markets follow six to twelve months later. Those who have well-structured content with clean schema markup will benefit earlier from better AI visibility.
What does a 2.6 percent CTR mean for position 1 in my SEO strategy?

Anyone who wants to generate traffic needs visibility in AI Overviews and Preferred Sources – meaning structured content, clean schema markup, and recognizable authorship.
