It’s difficult to conceive of the internet we know today — with information on every topic, in every language, at the fingertips of billions of people — without advertising as its economic foundation. But as our industry has strived to deliver relevant ads to consumers across the web, it has created a proliferation of individual user data across thousands of companies, typically gathered through third-party cookies. This has led to an erosion of trust: In fact, 72% of people feel that almost all of what they do online is being tracked by advertisers, technology firms or other companies, and 81% say that the potential risks they face because of data collection outweigh the benefits, according to a study by Pew Research Center. If digital advertising doesn’t evolve to address the growing concerns people have about their privacy and how their personal identity is being used, we risk the future of the free and open web.
That’s why last year Chrome announced its intent to remove support for third-party cookies, and why we’ve been working with the broader industry on the Privacy Sandbox to build innovations that protect anonymity while still delivering results for advertisers and publishers. Even so, we continue to get questions about whether Google will join others in the ad tech industry who plan to replace third-party cookies with alternative user-level identifiers. Today, we’re making explicit that once third-party cookies are phased out, we will not build alternate identifiers to track individuals as they browse across the web, nor will we use them in our products.
We realize this means other providers may offer a level of user identity for ad tracking across the web that we will not — like PII graphs based on people’s email addresses. We don’t believe these solutions will meet rising consumer expectations for privacy, nor will they stand up to rapidly evolving regulatory restrictions, and therefore aren’t a sustainable long term investment. Instead, our web products will be powered by privacy-preserving APIs which prevent individual tracking while still delivering results for advertisers and publishers.
