Data collection. We started with the manually collected and annotated dataset of 300 websites described in Soe et al. (2020). The dataset of the Soe et al. (2020) is available on https://github.com/videoworkflow/cookiepopup. We split this dataset and use it in training and testing. This **data** set describes the cookie banners that were encountered in each of the visited websites. Each website was visited on a browser running on a laptop computer in an Incognito mode by a reviewer who recorded information about the websites containing cookie banners. All websites were news outlets, in English or in a Scandinavian language.
