Ad filtering refers to the process of selectively blocking or removing advertisements from online content, typically in order to improve the user’s browsing experience. This can be achieved through the use of specialized software or browser extensions that target and eliminate unwanted ads, pop-ups, and other forms of online advertising. Ad filtering is often used to reduce distractions, increase page loading speed, and protect against potentially malicious ads. It allows users to customize their online experience and only view ads that are relevant and non-intrusive, making for a more enjoyable and efficient browsing experience.
