data In recent years, tracking advertisements have been used to deliver advertisements based on the user’s preferences and attributes based on the user’s browsing history.
For example, after visiting the electronics retailer’s e-commerce site several times with the intention of purchasing home appliances, the next day, when I browse the Internet again, I see a website completely unrelated to the electronics retailer’s e-commerce site. Have you ever had the experience of only seeing advertisements for home appliances that you were looking for yesterday?
The reason why we know that you have visited an electronics retailer’s e-commerce site is because we refer to the visit information that is left behind when you browse a website called a cookie. There are also ad blocking tools that allow you to refuse tracking of cookies.
