On February 15, 2018, Chrome will stop showing ads on websites that are not compliant with the Better Ads Standards. In order for site owners to understand the impact that this would have on their site, they can test the functionality by forcing this filtering to be active while they have Chrome's DevTools open. However, this behavior would normally only take effect on sites found to be noncompliant with the Standards for more than 30 days.
These instructions apply for Chrome on Windows, Mac, Linux, and Chrome OS.
Open Chrome's DevTools: click the three dots menu in the upper right corner of Chrome, and select More tools -> Developer tools. Alternatively, you can open DevTools by pressing Command+Option+I (Mac) or Control+Shift+I (Windows, Linux). In the new panel that opens, click the three dots menu and select Settings Under Network, check Force ad blocking on this site Try loading pages, leaving the DevTools panel open. If the DevTools panel is closed, ad blocking will cease to function.
