Can your Internet Service Provider SEE and SHARE your browsing history?

Yes, your Internet Service Provider can definitely see what you do online and even share that information with others to help them sell you things.

Imagine you send a postcard through the mail instead of putting your secret letter inside an opaque envelope. Your ISP is like the postal worker who can read the front of every postcard before it reaches its destination. They know exactly where you are sending and receiving messages, even if they cannot always see the tiny handwriting inside.

When you browse the web, your ISP sees which websites you visit. It is like a security camera watching you walk past different shop windows on a street. If you look at a shoe store window, then head to an ice cream shop, the camera records that path. They might not know why you are buying those shoes or how sweet the ice cream is, but they definitely see that you visited them. This means your ISP knows roughly what topics interest you, like sports, cooking, or video games.

Yes, they can share this "postcard" information with other companies. Think of it like a librarian handing out a card that says "This person loves dinosaurs" to every shop in town. If your ISP shares the list of places you visit, advertisers might use that data to show you ads for dinosaur toys or paleontology books on TV or websites. They do not usually read the private content of your messages, but they can see the address labels very clearly. So, while your secrets are safe inside the envelopes, the envelopes themselves are often open for others to glance at and learn from.
