What Happens When You Click Accept All on Every Website for a Year

Clicking "Accept all" on a cookie banner is the fastest way to get to the page. Do it on every site for a year and nothing dramatic happens on any single day. The effect is gradual: more companies collect more about you, and the picture they build gets sharper.

What one click allows

A consent banner usually lists partners: ad networks, analytics firms, data companies. On many news and media sites, the list runs to hundreds. "Accept all" lets all of them set cookies and collect data about your visit, such as the page, your device and your rough location.

What builds up over a year

• A browsing history held by others: the same ad companies appear on thousands of sites, so they see a large share of where you go.
• Interest profiles: your visits are turned into categories, such as "new parent", "car shopper" or "interested in debt relief". See how ad networks build a profile.
• Retargeting: products you looked at follow you around the web. See how retargeting works.
• Shared data: during ad auctions, details about you and the page are sent to many bidders, not just the winner.
• Linked identities: when you sign in or enter an email on a site, your browsing can be tied to that address.

What it doesn't do

Accepting cookies doesn't give sites your passwords or install anything harmful. Many cookies are needed for sign-ins and carts and are set whatever you choose. The issue is the scale of tracking, not a single click.

Can you undo it?

• Change your choice: in the EU and UK, withdrawing consent must be as easy as giving it. Look for "Cookie settings" or "Privacy choices", often in the site's footer.
• Clear cookies in your browser settings. This removes what's stored, but not data companies already collected.
• Ad settings: turn off personalized ads in your Google and Meta accounts.

An easier way to say no

Rejecting is often made harder than accepting. Cookie Auto-Reject clicks the reject or "necessary only" option on many banners for you. When a banner has no reject button, it opens the preferences screen and leaves the rest to you.

Other steps

• Block third-party cookies in your browser.
• Turn on Global Privacy Control where your browser supports it. See Do Not Track and Global Privacy Control.
