Many website owners are unaware of all the cookies their website places, especially when you use various plugins, external scripts or marketing tools. In fact, these can add cookies without you immediately realizing it.
Use specialized tools such as Cookiebot, CookiePro or GDPR Cookie Scan that automatically identify and categorize all cookies on your website. These tools crawl your website and create a comprehensive report of all cookies found.
Open your website in Chrome, right-click, choose "Inspect" and go to the "Application" tab and then "Cookies. Here you will see all the cookies that are currently active on the page you are visiting.
If you are using GTM, check which tags are implemented. Each tag can set different cookies. GTM's preview mode can help you see which tags and cookies are activated during your Web site visit.
Your Web developer can provide an overview of all implemented cookies and may be able to explain why they are needed.
It is important to conduct regular cookie audits, as your website may be constantly changing due to updates and new features.
Once you know what cookies your website uses, you can implement a proper cookie banner and update your privacy policy to transparently inform visitors about your cookie use.
As a user, you can easily delete all your cookies on any site you visit. You can read exactly how to do that in this step-by-step guide.
Also, your browser allows you to delete all your cookies on all sites at once. Deleting all cookies has several consequences. You have to log in again on websites where you were previously logged in and shopping carts on web shops are emptied. Personal preferences such as language settings disappear and websites no longer recognize you as a returning visitor. You may see less relevant ads and some parts of the website may temporarily not work properly. After deleting cookies, you start with a clean slate on the Internet, so to speak, which can be beneficial for your privacy, but can also cause some inconvenience.
Deleting cookies can be wise for your privacy and security. By regularly clearing cookies, you reduce the amount of personal data that Web sites collect about you. This is especially useful on public computers or if you are concerned about tracking. On the other hand, it causes inconvenience because you have to log into Web sites again, lose preferences and lose personal settings. For balance, you can selectively delete cookies from websites you don't trust, while keeping cookies from websites you use regularly. Also, on the websites you don't trust, you can refuse cookies in their cookie banner (if their cookie banner is functioning properly, of course).
Every website asks to accept cookies because of European privacy laws (AVG/GDPR) and the ePrivacy Directive. These laws require websites to ask permission before setting non-essential cookies. So every time you land on a new site, that site will ask that same question of you. Companies like to use these cookies to analyze visitor behavior, personalize content and show targeted ads. By using a cookie banner, they comply with legal requirements as well as trying to get your permission for their marketing purposes.
Without explicit permission, you may only set strictly necessary cookies that are essential to the functioning of your website. These are functional cookies that enable basic functions such as navigation, shopping carts and remembering login information. They also include security-related cookies that detect fraud. All other cookies, such as analytical, marketing and tracking cookies, require prior user consent under the AVG/GDPR and ePrivacy Directive, even if they are anonymized.
