Tagging users (without a signature)
The DSP can recognize users who visit a website. This helps the DSP make conclusions about users' interests and select appropriate advertising.
When users visit websites, they can be tagged with a label containing custom data as a string of up to 200 characters. The website, the RTB host, and the DSP cooperate in this process.
- The computer, laptop, or smartphone makes a request to the website. The site page has a “pixel” for transmitting requests to the RTB host.
- The “pixel” sends a request from the website page to the RTB host for tagging the user. The request is not associated with ad impressions and does not initiate an auction.
- If an error occurred, the HTTP 404 response is returned.
- If tagging was successful, the HTTP 200 response is returned.
