How UK websites track you, in numbers
Every check people run on Browser Monster adds to this dataset. We visit each homepage three times from London (doing nothing, clicking reject, clicking accept) and record what loads. Filter it, share the view, or download it.

“Before choice” and “after reject” count cross-site tracking companies. Downloads include every column for the current filters.
These are observations from one location at one time, homepage only; ads and banners change between visits. Some requests after rejecting may be strictly necessary services. Nothing here is proof that a site broke the law. Sites appear once they’re on our list or two different people have checked them.
