Dwell time refers to the amount of time a user spends on a webpage after clicking a link from a search engine results page (SERP) before returning to the search results. It is often used as an indicator of content relevance and user engagement. A longer dwell time typically suggests that visitors found the page useful or interesting, while a shorter dwell time may indicate that the content did not meet their expectations. Search engines may use dwell time as one of many factors to assess the quality and ranking of a webpage.
