ChatGPT

Prioritize ChatGPT if buyers research outside Google and rely on a single assistant for most decisions, especially in B2B and developer-oriented categories.

Prioritize

Google AI Overviews

Prioritize Google AI Overviews if buyers still start in Google Search and you need to defend visibility above the fold on commercial-intent queries.

What this means for your brand

ChatGPT and AI Overviews routinely name different brands for the same prompt.

If you only track AI Overviews, you miss buyer journeys that never start in Google.

If you only track ChatGPT, you miss the in-SERP displacement happening on your branded queries.
