The main purpose of this cookie is to collect information about visitor activity to help us understand how people interact with our site. It tracks metrics like page views and how users navigate the site to help us optimise and improve the website's layout and content. It also helps the Jetpack Stats system recognise returning visitors. The data collected is grouped anonymously, meaning it tracks general user behaviour rather than your specific personal identity.
