Google signals gradual shift from classic search to AI Mode

Sundar Pichai’s clearest message was not that classic Search is disappearing overnight. It was that Google sees the move into AI Mode as a continuum, and that matters because it turns the new interface from a side feature into the likely default path for searchers. For publishers and SEOs, the warning is blunt: blue-link traffic may increasingly become the handoff layer, not the destination.

Google has already been laying the groundwork. It introduced AI Mode as an experimental Search experience in March 2025, then said at I/O 2025 that the feature was rolling out to everyone in the United States through Search. By May 2025, Google said millions of people were already using AI Mode in Labs to ask longer, harder questions and discover new websites and businesses. That is not a tentative pilot anymore. It is a product path.

The same pattern showed up with AI Overviews. Google launched them in 2024, said in May of that year that links inside AI Overviews were getting more clicks than if the same page had shown up as a traditional web listing, and then said by October 2024 that the feature had expanded to more than 100 countries. At I/O 2025, Google called AI Overviews one of the most successful launches in Search in the past decade and said people using them were happier with results and searched more often. That is the clearest signal yet that Google thinks answer-first search can still drive usage, not just replace it.

The business case is just as important. Alphabet said Search revenues were growing alongside features like AI Overviews, AI Mode and Lens, and Pichai said on Alphabet’s Q2 2025 earnings call that AI Overviews had more than 2 billion monthly users across more than 200 countries and territories and 40 languages. Google has also kept repeating that ads remain in clearly labeled slots, which tells advertisers the monetization model is meant to survive the interface shift. In other words, Google is not betting against Search economics. It is betting that Search can be remade without breaking them.

For SEO and publishing teams, the real issue is where the clicks go once the interface becomes more conversational. Google keeps saying its AI features send people to a wider diversity of websites and surface more complex, longer queries, but the old playbook of chasing standard rankings alone looks increasingly thin. The content most likely to survive in AI Mode is the material that can be cited, summarized, and trusted inside the answer layer itself, while the rest of the web fights for what is left of the click.
