The marketing cookies you can refuse on many sites allow you to see personalized advertising after a site visit because your browsing habits and interests may be tracked. Refusing these cookies does not mean you will no longer see ads. You will still be served ads online, but they will not be tailored to your interests or browsing habits. If you reject marketing cookies, you will see more random and possibly irrelevant ads. The question is what you consider "unwanted. Irrelevant ads or being tracked across different Web sites?
For privacy-conscious users, third-party marketing cookies are the most problematic because they track you across multiple Web sites and build up a comprehensive profile of you. Social media cookies can also link your browsing habits to your social media profiles, which many people consider an invasion of privacy. If you have fewer problems with personalized ads but want to maintain some control, you can choose to accept only first-party cookies from websites you visit regularly. You can also be selective in which websites get permission for marketing cookies.
Those who really don't want to see unwanted advertising are better off considering paid subscriptions for services you use often, as many platforms offer ad-free versions. In addition, some browsers today have built-in privacy protections that automatically block third-party cookies. Refusing marketing cookies does not completely solve the problem of unwanted advertising. It does reduce the extent to which you are tracked online, but may result in less relevant ads. The best strategy depends on what you perceive as "unwanted": being tracked or seeing irrelevant ads.
It is important to understand that the Internet and ads are inextricably linked. Advertisements fund the free content and services we use every day. Completely avoiding online advertising while actively using the Internet is simply not realistic. It is an inherent part of the experience. Instead of wondering how to avoid all ads by rejecting cookies, it may be more convenient to accept that marketing cookies work to your advantage from a personal perspective. They ensure that you see ads that somewhat match your interests and needs, rather than completely random ads that are totally irrelevant to you. You won't stop seeing online ads if you refuse cookies in a cookie banner in any case.
Only functional cookies may be placed without permission. Tracking and analytical cookies do require consent. This consent requirement is stipulated in privacy laws, such as the General Data Protection Regulation (AVG) in Europe. Websites must clearly inform visitors about which cookies they use and for what purpose. Therefore, on your first visit to a website, you will often see a cookie notice in which you can indicate which categories of cookies you accept.
The different types of cookies we distinguish between are: functional cookies, analytical cookies and tracking cookies.
Functional cookies are essential to the functioning of a website. For example, they remember your login information, language preferences or what's in your shopping cart. These cookies do not collect personal information and are only used to make the website work correctly.
Analytical cookies help website owners understand how visitors use their website. They collect information such as which pages are most visited, how long visitors stay on a page, and where they might experience problems. This information is used to improve the user experience. Well-known examples are Google Analytics and Hotjar.
Tracking cookies, also called marketing cookies, track your browsing habits across websites. They build a profile of your interests and preferences in order to show targeted ads. These cookies can recognize you when you visit different websites that are part of the same advertising network. Third-party tracking cookies are placed by parties other than the website you visit, such as ad networks or social media companies.
In addition to these main categories, preference cookies (preference cookies) and performance cookies (performance cookies) are sometimes distinguished, but these often fall under the broader categories of functional or analytical cookies. The classification may vary from website to website, but the legal requirements for consent remain the same: functional cookies may be placed without consent, while analytical and tracking cookies require explicit consent in most cases.
Third-party cookies are cookies created by other websites, such as Google and Facebook. These sites may store cookies and other data about you to personalize your user experience. These cookies are set by domains that do not match the domain of the website you are currently visiting.
The main feature of third-party cookies is that they can track you across multiple Web sites. For example, if you visit an online store that has implemented a Facebook pixel, Facebook can record your activity on that site. Then, on a news Web site, you may see ads based on products you have previously viewed.
