With the launch of Chrome 71 last December, Google began filtering ads in North America and Europe into pages that displayed abusive ads.
Today, Google has announced that it will extend the ad filter to the rest of the world from 9 July to 2019.
In ad filtering, Chrome follows the standards set by Google for the best ads (guess which ones). So Google's browser can determine whether a site is displaying abusive ads or not.
Examples of abusive ads include pop-up ads, auto-playback videos, full-screen banners, and large sticky ads. A complete list of the least-favored ads based on Google's best-performing ads can be found below.
Today, the Coalition for Better Ads announced that it will be expanding its Better Ads Standards worldwide from July 9, '19. As Chrome follows the same standards, Google decided to extend the functionality in its browser on the same date to stay aligned with the Coalition.
For page administrators whose sites repeatedly display such types of ads, Google will alert them through Ad Experience Report. Administrators will then have 30 days to solve the problems, or Chrome will start to cut ads on the site.
"Chrome enforcing Coalition for Better Ads standards has inspired many website owners to improve their ad-serving experience in a way that benefits users," he said. Press release of Google.
In the US, Canada and Europe, website owners have made changes to their page ads. As of January 1, 2019, two-thirds of all publishers who did not comply with the Better Ads Standards are now in good standing. In addition, out of the millions of sites we have browsed to date, we filter ads by less than 1%.
