How the AI search volume metric works in LLM Mentions
in
While working with endpoints of the LLM Mentions API, you may notice that the values of ai_search_volume for the same keyword may vary significantly depending on the selected platform type. The difference in values of ai_search_volume for Google and ChatGPT is natural because ai_search_volume is calculated differently for both platforms.
Let’s explain to you how.
1 AI search volume for Google AI Overview mentions
If you choose google as a platform type while sending a request, the ai_search_volume values are derived directly from the Google Search Volume. That’s because the mentions data is captured for AI Overview features, which appear as features in Google SERPs. Thus, the search volume data can be sourced from the same Google keyword data used in traditional SEO keyword research.
For example, let’s assess the AI search volume of the keyword “renault” in Google AI Overviews for the United States. The Aggregated Metrics endpoint is the best suited for this task.

In the location array of the result, you can see that the ai_search_volume of the keyword “renault” in the US is 7383810.
2 AI search volume for ChatGPT mentions
For the chat_gpt platform type, the ai_search_volume is calculated using a special algorithm. The algorithm calculates search volume based on the data from the Google’s People Also Ask section, which is significantly important for ChatGPT. The People Also Ask sections suggest related queries in a question-answer format, displaying questions relevant to the target topic.
For LLMs such as ChatGPT, these conversational queries are seen as useful and considered when generating responses. Thus, to calculate ChatGPT AI search volume, we collect all People Also Ask questions that include the target keyword and count them.
Let’s make another request to the Aggregation Metrics endpoint to see whether the search volume for the “renault” keyword in ChatGPT differs from that in Google AI Overviews.

As you can see, in the locations array, the ai_search_volume of the target keyword in ChatGPT is 59196, which is significantly lower than in the AI Overviews.
In short, the ai_search_volume for Google and ChatGPT differs because this metric reflects query popularity on each platform independently and is calculated differently.
3 AI search volume in aggregation endpoints
Besides, it is worth noting that in aggregation endpoints (Aggregated Metrics, Cross Aggregated Metrics, Top Domains, and Top Pages), we separately provide the total ai_search_volume value. The total search volume is calculated as the sum of the AI search volumes for all LLM mentions found for a specific target (or a set of targets in Cross Aggregated Metrics).
Let’s demonstrate where you can find total ai_search_volume using the Top Domains endpoint as an example.
