65%<\/p>\n

of global browser traffic runs on Chrome.
\nBy January 2027, all major browsers must include a built-in opt-out signal under California\u2019s Opt Me Out Act (AB 566)
\n<\/small><\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n<\/div>\n\n\n\n

Right now, Global Privacy Control (GPC) affects a relatively small share of your website traffic. It\u2019s built into privacy-focused browsers like Brave, DuckDuckGo, and Firefox, and available as extensions for Chrome and Edge. Although 12 states already require you to honor this signal, most marketing teams haven\u2019t thought twice about it.<\/p>\n\n\n\n

In October 2025, California Governor Newsom signed AB 566, the California Opt-Out Preference Signal Act (Opt Me Out Act <\/strong>in shorthand), into law. It requires every browser, including Chrome, Safari, and Edge, to include a built-in opt-out preference signal by January 1, 2027.\u00a0<\/p>\n\n\n\n

This is when GPC \u2014 the most widely adopted opt-out signal \u2014 will go mainstream<\/strong>. With the addition of a native opt-out toggle that only has to be set once, the volume of users automatically telling your website not to sell or share their data will likely soar.<\/p>\n\n\n

What is GPC and Why Should Marketers Care?<\/h2>\n\n\n\n

Global Privacy Control is a browser-level signal that automatically tells every website a user visits not to sell or share their personal data. It works differently from the old Do Not Track standard in one critical respect: GPC has legal enforcement behind it. (W3C GPC Specification<\/a>)<\/p>\n\n\n\n

The CPRA amended the CCPA to require businesses to treat GPC signals as valid opt-out requests. This is an obligation that the California Attorney General has reinforced through enforcement actions. And California is not the only state paying attention.<\/p>\n\n\n\n

12 U.S. states now require businesses to honor GPC or equivalent universal opt-out signals<\/strong>: California, Colorado, Connecticut, Delaware, Maryland, Minnesota, Montana, Nebraska, New Hampshire, New Jersey, Oregon, and Texas. <\/p>\n\n\n\n

In September 2025, three state attorneys general \u2014 California, Colorado, and Connecticut \u2014 launched a coordinated enforcement sweep specifically targeting GPC violations.<\/p>\n\n\n

Fines are already landing and getting larger. <\/div>\n

Disney: USD 2.75M (Feb 2026, largest CCPA fine ever). Healthline: USD 1.55M (Jul 2025). Tractor Supply: USD 1.35M (Sep 2025). Sephora: USD 1.2M (2022). Each was cited for failing to honor opt-out signals. CCPA penalties can reach USD 7,988 per intentional violation, and each visitor whose signal is ignored can count as a separate violation.

What Happens to Your Website When GPC Goes Mainstream<\/h2>\n\n\n\n

When a visitor arrives with GPC enabled, your website is legally required to honor their opt-out automatically and display a notification that it has done so. There is no consent banner prompt, and you can\u2019t display the consent banner to offer or request that they change their preference. The visitor made their choice at the browser level before they ever reached your site.<\/p>\n\n\n\n
