Cookies are small text files that the user viewed on a web browser. Cookies are small text files. Each cookie holds a small amount of data such as a single ID linking a user to a particular website. This encourages the user to experience more personal as the browser recalls the user. Marketers and advertisers have used information stored in a cookie and its ability to monitor online user activity to serve consumers more relevant advertising and increase ad-efficiency.
The mobile Internet:
Cookies exist just like on the desktop on the mobile site. Users using mobile web browsers to browse the internet receive cookies put on their browsers. Every mobile browser has different cookie settings just like desktop browsers and handles cookies for the first party and third party. Cookies are essentially completely available on the mobile site. The cookies in mobile browsers are mostly limited to resetting when the browser is closed or when your phone is switched on/off.
Cookies also exist in applications where a browser is required to view or display certain contents of an application. But cookies are "sandboxed" totally in apps. Cookies from one application can therefore not be shared with another application, and remain confidential to each application. This is a handicap for mobile advertisers, as tracking user activity and behavior across apps is incredibly difficult. The basis of ad targeting is being able to monitor user activity and behavior, and so the inability to do this makes mobile marketers highly demanding to maximize ad efficiency. The mobile app sector requires a substitute for the cookie, which can be used to monitor user activity across apps since mobile app usage accounts for nearly 86 percent of mobile users over just 14 percent on the mobile Web. The mobile advertising ecosystem is in its infancy and businesses still experiment with various approaches for overcoming inefficient and unreliable mobile cookies. Although some businesses have different levels of success in overcoming a cookie problem, there is still no reliable way of tracking users through applications and various mobile devices. It takes some time, but a way to substitute cookies on mobile devices
