## What it is and how it works

People use it to avoid annoying ads, reduce tracking, speed up pages or save data. Well-known tools include extensions such as AdBlock, Adblock Plus and uBlock Origin, and browsers such as Brave; none of them belongs to Google. Some allow ads that meet certain quality criteria.

For publishers and advertisers it means lost impressions and revenue, and it has prompted responses such as walls asking users to disable their blocker, subscription models and standards for less intrusive ads. Technical changes to browsers’ extension systems also affect how these blockers work.
