Google's "People Also Search For" feature is a tool that appears at the bottom of the search engine results page (SERP) and provides users with a list of related search terms. This feature is designed to help users refine their search and find the information they need more quickly.
The "People Also Search For" feature uses a variety of signals, such as the user's search history, location, and language, to generate a list of related searches. It can also use information from other users who have conducted similar searches to suggest additional keywords.
The main benefit of the "People Also Search For" feature is that it helps users discover new topics related to their initial search. It can also help users better understand the context of their search and provide them with a more comprehensive set of results.
