Google is enabling its built-in ad blocker for Chrome tomorrow (February 15th). Chrome’s ad filtering is designed to weed out some of the web’s most annoying ads, and push website owners to stop using them. Google is not planning to wipe out all ads from Chrome, just ones that are considered bad using standards from the Coalition for Better Ads. Full page ads, ads with autoplaying sound and video, and flashing ads will be targeted by Chrome’s ad filtering, which will hopefully result in less of these annoying ads on the web.
Google is revealing today exactly what ads will be blocked, and how the company notifies site owners before a block is put in place. On desktop, Google is planning to block pop-up ads, large sticky ads, auto-play video ads with sound, and ads that appear on a site with a countdown blocking you before the content loads. Google is being more aggressive about its mobile ad blocking, filtering out pop-up ads, ads that are displayed before content loads (with or without a countdown), auto-play video ads with sound, large sticky ads, flashing animated ads, fullscreen scroll over ads, and ads that are particularly dense.
“The majority of problematic ad experiences are controlled by the site owner,” explains Chris Bentzel, Chrome engineering manager. As a result, Google is taking a three-step process to tackling these bad ads by evaluating sites, informing sites of issues, and then allowing sites to correct problems before a block is enforced.
Google is evaluating sites based on the Better Ads standards and then rating them as a pass, warning, or failing. Site owners can access these evaluations using an API, and sites can be re-reviewed after bad ads have been addressed. If a site has been found to have a high number of violations and the owner ignores Google’s notification of these violations then Chrome will start blocking ads on the site after 30 days.
