The latest numbers show ChatGPT’s market share rebounding to 80.1%, up from 77.6% a month ago.
Here’s how the competition stacks up:
These numbers are part of Similarweb’s bigger “AI Global” report (PDF link).
The most important finding may be that traditional search engines aren’t growing:
Traditional search shows a steady decline of -1% to -2% compared to last year. It’s important to note, however, that Google has seven times the user base of ChatGPT.
While AI is changing search, some AI categories are growing faster than others:
On the other hand, some AI areas are shrinking, including Writing and content Generation (-12 %), Customer Support (11%), and Legal AI (70%).
AI’s impact goes beyond just search engines. Other digital sectors facing big changes include:
Design platforms are still growing at +10% year over year, suggesting that AI might be helping rather than replacing these services.
Traditional SEO still matters, but it isn’t enough. As traditional search traffic drops, you need to branch out.
Similarweb’s data shows consistent negative growth for traditional search engines alongside ChatGPT’s dominant market position, indicating a significant shift in information discovery patterns.
The takeaway for search marketers is to adapt to AI-driven search while keeping up with practices that work in traditional search. This balanced approach will be key to success in 2025 and beyond.

It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using ‘Content here, content here’, making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for ‘lorem ipsum’ will uncover many web sites still in their infancy.
