The toolbar can now be used to block ads from your website that you think are not suitable for your visitors.
The company spoke about the update:
Here’s how it works, once you’ve installed the toolbar: Just as before, you can view account performance in a widget in the corner of your Chrome window, as well as ad overlays on the page itself. Clicking on one of the ad overlays will now bring up additional information about that ad unit, including the name of the ad slot, performance metrics, the destination and display URL of the ad, and a preview of the ad. Below the ad preview, you can take action on either the ad or the URL: If you are using the Ad Review Center, you can choose to block the ad directly and your action will be reflected the next time you visit the Ad Review Center. If you block a URL, it’ll be added to your URL filter list.
