What are the different tracking methods in advertising?
While reading about ad-tech you cannot miss hearing about terms like cookie, first-party, third-party and the likes. I have tried to explain them below:
Cookie - I store information on you in your own browser.
First-party cookie - You visited my website so I know about you.
Third-party cookie - You visited a website where I placed my ad so I know about you.
Persistent cookie: As the name suggests i store information about your preferences and make your access convenient for future visits. They can stay for a long as two years hence can give information on the user path as well.
Retargeting - You came to my website. Left before completing an action (Purchase, form fill, etc.) so I follow you wherever you go on the web.
Link decoration - Adding extra information to the URL in a link that a person clicks on. (Piggybacking)
Fingerprinting - I know about your device (or browser) based on its specific or unique config. I don't store this info on your browser but on a server in a database.
Cookie respawning: Cookie respawning is the process of recreating browser cookies from information that has been deleted. With cookie respawning, companies take information stored in flash cookies and use it to recreate a cookie in the browser.
Flash cookie: A Flash cookie, is a text file that is sent by a server to the client when the user's browser requests content supported by Adobe Flash, a popular plug-in. They are not stored in the browser and have to be separately deleted through Adobe flash player settings.
Cookie poisoning: It is a method adopted by an unauthorized person to access and control the data in a cookie, to steal someone’s identity or financial information
