Cookies. The kind without chocolate chips.

Ever wonder how companies are able to send you an email about something you looked at on their website a few hours before? Read on to learn more.

What is a cookie?

A cookie is a little bit of code placed by a website on your computer while you are browsing websites. They are used to reference certain data about you and your previous experience browsing that website. 

How do cookies actually work?

Cookies remember information such as items you have placed in a shopping cart, names and addresses, passwords and credit card numbers. Cookies are often used to gather information on a user’s browsing history. While some cookies are helpful in maintaining your preferences on a website, some cookies are placed by a third party (an advertising network or an analytics company) to monitor your behavior over time. Once these third party cookies have enough information about you, they can get a detailed history of your site visits to deliver ads tailored to your specific interests.

You can safely assume that all websites use some form of cookies.

Only 30% of Web users delete cookies on a monthly basis.

According to Google, most people don't regularly delete their cookies–which can be a bad thing, if you're concerned about your privacy online. (https://www.e-nor.com/blog/google-analytics/cookies-and-cookie-deletion-in-google-analytics).

The following popular sites below use something called a Persistent Cookie which means these cookies remain on your computer even after you close your browser until they either expire or are manually deleted. (https://w3techs.com/technologies/details/ce-cookies/all/all)
