OpenAI Puts ChatGPT Web Queries at a Fifth of Google Volume

OpenAI estimates that ChatGPT handles search-like queries at roughly one-fifth the volume of Google searches, according to Search Engine Journal. The comparison counts ChatGPT questions that send the service to the web, rather than every question people ask the assistant.

The distinction matters when interpreting the estimate. ChatGPT can receive many kinds of questions, but the figure cited by OpenAI focuses on the subset that triggers web use. On that basis, Google’s search volume is approximately five times the volume OpenAI attributes to ChatGPT’s search-like activity. The comparison should not be read as a count of all interactions with ChatGPT.

Search Engine Journal also notes that traffic data presents a different picture. Query volume and traffic are not interchangeable measures: a question sent to a service is a different unit from a visit measured in traffic data. As a result, the estimate offers one way to compare activity, while traffic figures provide another. The difference is a reason to check what each measure counts before using either to assess the relative scale of the services.

For marketing teams, the figures are best treated as a comparison of specific activity rather than a complete measure of audience opportunity. They do not, by themselves, establish how many people use either service, how often users follow links, or how much traffic individual publishers receive. Nor do they show whether a particular brand appears in responses to relevant questions. Those questions require separate evidence from the metrics used to produce the volume comparison.

What this means for marketers

Keep the counting method alongside the headline figure in reports and planning discussions: OpenAI’s estimate covers ChatGPT questions that send it to the web. When evaluating search performance, distinguish query-volume comparisons from traffic measurements, and use your own reporting to assess visits and other outcomes. Avoid treating the one-fifth estimate as a direct proxy for a brand’s likely reach or referral traffic.
