Anyone who uses the internet encounters them on a daily basis: cookies. You probably recognize this: you have looked online once for a holiday via a travel agency, and suddenly you see advertisements from that travel agency on every website you visit. This way you are reminded again and again to book your holiday with exactly that travel agency. That is what those cookies do. You can always choose to accept them, which is often the best option. Some websites do not work with all the functionalities if you do not accept cookies. Ultimately, they are also there to improve the user experience on websites. However, it can sometimes be useful to delete cookies. Curious why and how you do this? You can read that in this blog. What are cookies? Cookies are small text files that are stored on your computer or smartphone by websites. Some cookies are necessary for the proper functioning of websites, other cookies are used for marketing or analytical purposes. They are also used for: User experience : If you have accepted cookies, websites can recognise you as a user. They remember the preferences you have indicated and your login information, so you do not have to log in again every time you close a page. Personalization : Cookies also ensure that advertisements are personalized. When you are surfing on a website, the cookies keep track of which pages you view. In this way, they create advertisements that match those that are likely to interest you the most. Tracking : Cookies keep track of how often and for how long you visit certain pages on a website. This allows web shops to see which products you have viewed and, based on that, recommend other products that may interest you. Cookies also ensure that your shopping cart remains filled, even if you visit other pages on that website in the meantime. Cookies ensure that websites load faster, login details are saved and your online preferences are remembered. This allows you to see personalized content and advertisements on the websites you visit. Why delete cookies? So cookies improve the user experience, but it can still be useful to delete them from time to time for several reasons: Privacy: Cookies collect personal information about your browsing activity to provide you with targeted recommendations and advertisements. To protect your online privacy, it is useful to delete these cookies regularly. Loading speed: Cookies make web pages load faster, because they are already stored on your device and do not need to be downloaded again. After a while, these cookies can take up a lot of storage space, which actually slows down the loading speed. Update preferences: Do you want to change your cookie preferences? Then also delete your cookies. For example, you can only allow necessary cookies, while you previously also enabled marketing cookies. Using shared devices: Do you use public or shared devices? Always clear your cookies after surfing the internet. If you don’t do this, the person after you can see your history and sometimes your accounts if you haven’t logged out. How do you delete cookies?
