Find out how many cookies Internet sites save to your system
A cookie is a little snippet of data that websites can save to systems of users connecting to them. While web browsers ship with options to block cookies by default or prompt users for action, the default way of handling cookies is to allow them to be saved automatically.
Cookies are not necessarily bad as they can be used for a variety of legitimate purposes such as saving the logged in state of a user or site preferences without account.
Cookies do have a bad reputation though which comes from the fact that they are used for tracking purposes. Generally speaking, you need to distinguish between first and third party cookies.
First party cookies are saved by the hostname you are on. If you visit Ghacks and my site would save a cookie to your system, that would be a first party cookie.
Third party cookies on the other hand are saved by external domain names, say a Facebook or Google ads cookie. This only happens if the site has embedded third party scripts on the other hand most of the time.
So, if you see Google Analytics or Google Ads being used on a site, chance is high that Google third party cookies are saved to your system.
Since services that drop cookies on systems can process those cookies whenever sites that embed their scripts are accessed, it is possible to use them for tracking purpose.
