Google plans to launch an ad blocker for its Chrome browser next year. The media giant has informed publishers that they have six months to prepare for its new ad-blocking tool that will be introduced in 2018, the Wall Street Journal reports. The new tool will be in a default mode integrated into the desktop and mobile versions of Chrome and prevent ads from appearing on We bsites that prove to offer a poor ad experience for consumers. Google will reportedly offer a self-service tool called the "Ad Experience Report" to help publishers prepare for the ad blocker, alerting them to inappropriate ads on their sites and how to deal with them. While Google hasn't announced its plans, it has spoken with publishers, agencies, and advertisers about them, according to the Journal.
