What are third-party cookies and how can you block them?

third-party cookies

You could have heard of third-party cookies somewhere, or somehow came across the term while browsing on your computer. They may not be that evening coffee snack, but something that could be the difference to your internet browsing. Being a small text file created by a website that is stored in the user’s computer, a cookie is either stored temporarily for a single session only or permanently on the hard disk, to provide a way for the website to recognize you and keep track of your preferences.

All cookies have an owner to whom they belong. The owner is the domain or party specified in the cookie; and they are commonly known to be either first-party or third-party. Say, if you visit dignited.com and the domain of the cookie placed on your computer is dignited.com, then this is a first-party cookie. If, however, you visit dignited.com and the cookie placed on your computer says stats-for-free.com, then this is a third-party cookie.

First-Party Personal Cookies

first-party cookie refers to a cookie created by the site that you are visiting. The browser sends a web request in the first context, and subsequently saves this data file to your computer under the site’s domain. In most cases, when you visit a site with these cookies, there will be a statement like: “We use cookies for analytics, performance, security, advertising and social media. You consent to our cookies if you continue to use our website.” To this, you are required to agree, if you do.

If you disable first-party cookies, a website could not keep track of your activity as you move from page to page. For example, if you visit an online shop site and you disable first-party cookies, you would be unable to purchase multiple items in the same transaction. Each time you add something to the cart from another page on the site, it would be treated as a new order.

Third-Party Cookies

Unlike the first-party, the third-party cookies are created by a website with a domain name other than the one you could be currently visiting. The purpose of these cookies is to track your browsing habits, which is why they are considered a violation of privacy. They are by default allowed by web browsers, as they are widely used by advertisers to track browsing history, but they can be blocked or disabled.

Blocking and deleting cookies

Like we said before, first-party cookies are necessary in order for you to be recognized as an individual by any site that you login to. If you disable them, a website could not keep track of your activity as you move from page to page. As well, disabling third-party cookies in your web browser can stop some types of tracking by advertisers and other third-party entities. This increases your user privacy and security.

It’s always a good idea to clear out these third-party cookies on a regular basis. Here’s how.
