Google announced at Google I/O 2026 that AI Mode has surpassed 1 billion monthly users globally, one year after its debut. AI Mode queries have more than doubled every quarter since launch, making it the fastest-growing product in Google Search history.
The scale of the shift is visible in how people are searching. The average AI Mode query is now triple the length of a traditional search query. More than one in six searches in the US now use voice or images. Image searches are growing over 40% month-over-month. Planning queries ('help me plan a trip to Tokyo', 'what should I consider when switching CRM providers') are growing 80% faster than overall AI Mode queries.
What This Means for AEO
The 1 billion user milestone is not just a product announcement. It is a structural shift in how brands get discovered. When search queries triple in length and shift toward planning and comparison, the brands that get cited are those that have invested in comprehensive, authoritative, conversational content, not those optimised for short-tail keywords.
The 80% growth in planning queries is particularly significant for B2B brands. Planning-stage queries ('what should I look for in an AEO platform', 'how do I evaluate AI visibility tools') are where vendor selection begins. Brands that appear in AI Mode answers at the planning stage are building consideration before the buyer has even formed a shortlist.
Google's own data suggests that AI Mode is not cannibalising traditional search, it is expanding the scope of what search can answer. For AEO practitioners, the implication is clear: the question is no longer whether to optimise for AI answers. It is how quickly you can build the content depth and third-party authority that AI Mode requires to cite your brand.
