Share of sessions refers to the percentage of total website visits that a particular page or section of a website receives. It is a measure of the overall traffic and engagement that a specific page or section generates within a given time period. This metric is often used in web analytics to understand the popularity and effectiveness of different pages on a website, and to identify areas for improvement. A high share of sessions indicates that a page is attracting a significant amount of visitors, while a low share of sessions may suggest that the page needs to be optimized or promoted more effectively.
