Google says it will preinstall an ad filter in Chrome starting early 2018 aimed at ads deemed “annoying” by the Coalition for Better Ads
Google's Chrome browser will soon come with preinstalled technology that will block the most annoying ads currently marring the web experience, the company confirmed on Thursday.
Context & Ripple Effects
Google has confirmed what sources described in an earlier report of ad-blocking plans inside Chrome: rather than block everything, the browser will target only the formats the Coalition for Better Ads deems annoying, starting early 2018. The confirmation lands alongside reporting that Google and Coalition partners are building a filtering tool aimed at publishers, which the IAB head insists is not an ad blocker.
The distinction matters because it puts Google — the web's largest ad seller — in charge of which ads survive in its own browser, a role third-party blockers like Adblock Plus have held until now.
First-order effects
- Publishers still running non-compliant formats — pop-ups, auto-playing video with sound, large sticky ads — face losing Chrome impressions entirely once the filter ships.
- Chrome's user base gets blocking by default with no extension install, shrinking the audience third-party blockers can claim.
Second-order effects
- Ad-tech vendors and publishers are pushed toward the Coalition's 'Better Ads' certification path, making the standards body — and Google's own publisher tooling — a gatekeeper for ad revenue.
- Rival browsers face pressure to adopt the same standards or become the destination for the heavy ad experiences Chrome strips out.
Third-order effects
- Enforcement of ad quality migrates from user-installed tools to the browser itself, and Google's own follow-through shows the pattern compounding: a global rollout of the blocker in mid-2019 followed by an expansion into disruptive video ads in 2020.
- If browsers become the de facto regulators of ad formats, industry bodies like the Coalition effectively set binding rules for the open web — with the biggest browser vendor holding the switch.
The trend: Web advertising is moving from user-enforced blocking toward platform-enforced curation, with the dominant browser deciding which ad formats are acceptable at scale.
