What Are Computer Cookies?
Remember the story of Hansel and Gretel, who were able to mark their trail through a dark forest by dropping cookie crumbs behind them? Well, web servers do the same for you by placing on your computer small text files about your activity on a particular website. Cookies are commonly used to store registration data like your name, email, the contents of a shopping cart, your preferred layout for a web page (language), what goods you might be looking at, and so on.
These types of cookies are first-party, because they’re set by the website you visit.
Why Are Cookies Terribly Tasteful for Advertisers?
Some cookies are “special” and virtually impossible to resist if you are an advertiser. This is because of another type of cookie.
Third-party cookies are set by advertisers or marketing and analytics platforms that collect your data in order to show you ads. There are ads on every website. When the ad loads, the ad network or advertiser sends a cookie that later may be recognized on future websites you visit that also have the advertiser’s ads.
The most terrible part, however, is that these guys talk to each other and share (read: “sell”) data about you to other companies in their advertising network. As a result, an entire network can get access to your information, including how you browse, what websites you visit, what purchases you make, or which articles you read.
As long as a third-party cookie lives, it will help advertisers collect data—quite sensitive sometimes—and share it with other companies without your control.That’s called tracking or cookie tracking.
How to Disable Cookies?
Below is a brief outline about the basic approaches to stop tracking. We’ve also outlined how to disable tracking on specific devices.
The fast but inconvenient way—incognito or private browsing mode.
Cons: Your internet service provider still has a list of all the websites you visited. The website you’re viewing might also keep a record of your stay.
The easy but short-term way—clear cookies via your browser. You can manually clear them any time.
Pros: It’s easy to update your browser settings. You should never have to download an app for this.
Cons: Mostly, it’s a bit of a procedure you should manually repeat every time you want to clear your digital footprint.
