¿What is a cookie?
A cookie is a harmless text file which is stored in your browser when you visit almost any website. The use of the cookie is that the website is able to remember your visit when you return to the page. Although many people are not aware of it, cookies have been used since 20 years ago, when the first World Wide Web browsers appeared.
¿What is a cookie NOT??
It is not a virus, a trojan, a worm, spam, spyware, or a pop-up.
¿What information does a cookie store?
Cookies do not usually store sensitive information about you, such as credit card or bank details, photographs, your DNI identity number or personal information, etc. The data that they store are technical, about personal preferences, customisation of content, etc.
The web server does not associate with you as a person, but rather with your web browser. In fact, if you usually browse with Internet Explorer and try to navigate on the same website with Firefox or Chrome you will see that the website does not realise that you are the same person because in reality it is associating with the browser, not the person.
¿What types of cookies exist?
- Technical cookies: They are the most basic and allow, among other things, to know when a human or an automated application is browsing, when an anonymous or registered user is browsing, and basic functions for the function of any dynamic website.
- Analysis cookies: They collect information about the type of browsing being carried out, the sections used most, products viewed, time zone, language, etc.
- Advertising cookies: Show advertisements according to browsing, country, language, etc.
¿What are own and third party cookies?
Own cookies are those generated by the website that 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 deactivate cookies?
So that you understand the effect that deactivating cookies can have we will give some examples:
- You will not be able to share content from the website on Facebook, Twitter or any other social network.
- The website will not be able to adapt its content to your personal preferences, as tends to happen in online shops.
- You will not be able to access the personal section of the website, for example, such as My account, My profile, or My orders.
- Online shops: It will be impossible for you to make purchases online, they will have to be made by telephone or by visiting the physical shop if one exists.
- It will not be possible to customise your geographical preferences such as time zone, currency or language.
- The website will not be able to carry out web analysis on visitors and web traffic, which will make it difficult for the website to be competitive.
- You will not be able to write in the blog, upload photos, post comments, or evaluate or vote on content. The website will also not know whether you are a human or an automated application which publishes spam.
- You will not be able to be shown sectored advertising, which will reduce the advertising revenue of the website.
¿Can you remove cookies?
Yes. Not only remove, but also block, generally or individually for a specific website.
