Aren’t cookies already limited to the site at which they were created??

What the fuck? You mean to tell me sites have been sharing cookies?

I thought all browsers only delivered cookies back to the same site.

The problem is that a website is generally not served from one domain.

Put a Facebook like button on your website, it's loaded directly from Facebook servers. Now they can put a cookie on your computer with an identifier.

Now every site you visit with a Facebook like button, they know it was you. They can watch you as you move around the web.

Google does this at a larger scale. Every site with Google ads on it. Every site using Google analytics. Every site that embeds a Google map. They can stick a cookie in and know you were there.

Is this also how they know which ads to feed you?

[–] Dave@lemmy.nz 58 points 2 months ago

Yes, it's the reason for the tracking. To sell more targeted ads.

If you're up for reading some shennanigans, check out the book Mindf*ck. It's about the Cambridge Analytica scandal, written by a whistleblower, and details election manipulation using data collected from Facebook and other public or purchased data.
