Similarweb data shows most ChatGPT users also use Google, overlap not replacement
Similarweb found that 93.7% of ChatGPT.com visitors in September also visited Google.com, while 14.1% of Google visitors also used ChatGPT.com, according to a Search Engine Watch report cited by Entrepreneur. The figures measure overlapping monthly website visits, not the order, frequency or purpose of those visits, and don't capture app usage.
GoKawiil's interpretation of the reporting above, not reported fact.
The data suggests AI search tools are not simply siphoning traffic away from Google but are being used alongside it, which could mean marketers need to track customer journeys across multiple platforms rather than relying on single-channel attribution. The author argues businesses should measure AI visibility, branded search and conversions together, treating AI assistants and traditional search as complementary discovery paths rather than competitors.
- 93.7% of ChatGPT.com visitors also visited Google.com in September, per Similarweb data
- Overlap in visits does not prove sequence, intent or purchase behavior
- Marketers are advised to track AI visibility and branded searches alongside traditional metrics rather than relying on last-click attribution
