Ad Filtering (Paperback)

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Ad filtering or ad blocking is removing or altering advertising content in a webpage. Advertising can exist in a variety of forms including pictures, animations, text, or pop-up windows. More advanced filters allow fine-grained control of advertisements through features such as blacklists, whitelists, and regular expression filters. Certain security features also have the effect of disabling some ads. The immediate benefits include quicker loading and cleaner looking Web pages free from advertisements, and lower resource waste. The immediate cost is decreased revenue to the website that was sustained by advertisements.
