Chrome removes ads from websites that violate Better Ads standards. The rules discourage the types of ads that are particularly annoying to people. If ads are being removed from a site you own, visit the Ad Experience Report. AdBlock for Chrome is a browser extension that blocks ads, meaning it removes ads from Chrome and provides protection against third-party trackers.
In fact, with more than 60 million users, AdBlock is the most reliable ad-blocking extension for Chrome available today. Millions of people around the world use AdBlock to block Chrome ads, improve page load speed and help protect their privacy. That's because AdBlock for Chrome is easy to use, fully customizable, and provides a dramatic improvement to your online experience. Because Google benefits greatly from ads and trackers, promoting effective ad blockers isn't always in their best interest financially.
However, Google's new manifest changes the way network request modifications work, since it eliminates the possibility for extensions to use dynamic filtering to search for and block ads. Google doesn't block YouTube ads, for example, because YouTube is part of Google and both sites benefit from those ads.
