There were reports a while back that Google was planning to incorporate some limited ad blocking features into its Chrome browser, and Google has now confirmed those reports and explained exactly what it’s planning. As the reports suggested, Google isn’t planning to implement a broad ad blocker but rather will block just those ads deemed annoying by the Coalition for Better Ads, of which Google is a member. It sounds like Google has started reaching out to publishers to explain the forthcoming change and will be providing detailed guidance on how they can ensure their sites are in compliance. As I said when the earlier reports surfaced, it’s smart for Google to be part of the push for limited ad blockers even if that may seem counterintuitive, because if it can focus that activity on egregious ads rather than all ads indiscriminately, it has a much better shot at protecting its own massive ad revenue than if others take more of a blanket approach. We can be certain that none of Google’s own sites or ad formats will be affected by this filter, but we can also guess that there will be something of an outcry from publishers feeling that Google is favoring itself while disadvantaging others. It’s going to be fascinating to watch this play out over the next few months.
