What is a cookie?
A cookie is a harmless text file that is stored in your browser when you visit almost any website. The purpose of the cookie is for the website to remember your visit when you return to browse that page. Although many people don’t know it, cookies have been used for over 20 years, since the first web browsers appeared for the World Wide Web.
What is NOT a cookie?
It is not a virus, trojan, worm, spam, spyware, or pop-up window opener.
What information does a cookie store?
Cookies do not usually store sensitive information such as credit card numbers, bank details, photographs, your ID, or personal data, etc. The data they store are technical, personal preferences, content customization, etc.
The web server does not associate you as a person, but with your web browser. In fact, if you usually browse with Internet Explorer and try visiting the same website with Firefox or Chrome, you’ll see that the site does not recognize you as the same person because it’s actually associating with the browser, not the person.
What types of cookies exist?
- Technical cookies: These are the most basic and allow, among other things, to know when a human or an automated application is browsing, when an anonymous user or a registered user is browsing, and basic tasks for the functioning of any dynamic website.
- Analytics cookies: These collect information about your type of browsing, the sections you use most, products viewed, time slot of use, language, etc.
- Advertising cookies: These show advertising based on your browsing, country of origin, language, etc.
What are first-party and third-party cookies?
First-party cookies are those generated by the website you are visiting, and third-party cookies are those generated by external services or providers such as Facebook, Twitter, Google, etc.
What happens if I disable cookies?
To help you understand the potential impact of disabling cookies, here are some examples:
- You won’t be able to share content from that website on Facebook, Twitter, or any other social network.
- The website won’t be able to adapt content to your personal preferences, as often happens in online stores.
- You won’t be able to access the personal area of the website, such as My account, My profile, or My orders.
- Online stores: You won’t be able to shop online — purchases will need to be made by phone or by visiting the physical store (if available).
- You won’t be able to customize geographic preferences such as time zone, currency, or language.
- The website won’t be able to perform web analytics on visitors and traffic, making it harder for the site to be competitive.
- You won’t be able to comment on the blog, upload photos, post comments, rate or score content. The website also won’t be able to tell whether you are a human or an automated application that publishes spam.
- Sector-specific advertising cannot be displayed, reducing the website’s advertising revenue.
- All social networks use cookies, and if you disable them, you won’t be able to use any social networks.
Can cookies be deleted?
Yes. Not only can they be deleted, but also blocked, either generally or for a specific domain.
