To guarantee the correct operation of our in-image advertising technology, we measure events related to the operation of our advertising via cookies.
To allow us to operate correctly with programmatic demand, Seedtag installs different cookies in browsers to synchronise users with direct and third-party partners. This synchronisation allows third parties to provide the most relevant advertising based on your preferences as a user.
To do this, we install advertising cookies, which are for customising publicity campaigns and displaying advertisements tailored to your preferences as a user. This lets Seedtag analyse and measure the delivery and effectiveness of the content sent by processing information on what content was displayed, with what frequency, how, for how long and whether any action was made on the content, for example, by clicking on it.
The table below summarises the cookies used and the periods for which the information collected is held:
