A Cookie is a tiny text file that a web server places on your computer when you visit a web page. The file is just composed of text, and it doesn’t run software code. When used by a website, the cookie can help make a webpage more user-friendly, for example by remembering your settings.
Cookies live in the memory of your web browser. Usually, a cookie contains:
Any page on the domain that created the cookie can read it. Cookies can be used for a wide range of reasons.
For example, when you add a product to your basket and you decide not to buy it right away but to think a little … and you come back a few hours later, you will see that your basket has been kept. This was done through a cookie.
In the majority of cases a cookie is stored as a 1st party cookie, meaning it will be stored for the domain you are visiting.
For example, if you visit Google then the 1st party cookie will be stored for pages within the Google domain. Any time you browse a page in this domain, the cookie’s data will be made available for use.
A 3rd party cookie allows cross-domain tracking for when a visitor starts on one domain and ends up on another.
Let’s say a user participates in an experiment on Google but ends up converting on Skype. As these are different domains, there is no way for a 1st party cookie to share data between the different websites. On the other hand, using a 3rd party cookie allows the user to be tracked across these domains.
3rd party cookies are disabled by default on Safari, meaning Convertize is unable to track Safari users unless 3rd party cookies are explicitly enabled.
You can make your browser stop accepting some or all cookies. But it’s worth noting that disabling cookies restricts the performance of websites.
Turning off cookies will stop websites tracking your visits, meaning some content designed to appear for returning users won’t appear.
All modern browsers let you control your cookie settings. Here’s a list:
