Impressions

GIF (Pixel)

Pixel URL's are structured slightly differently from the standard reporting URL's to avoid conflicts with query parameters. In general they follow this format:

https://data.withcubed.com/[aid]/cubedimpression.gif

For example

https://data.withcubed.com/[aid]/cubedimpression.gif?medium=[medium]&source=[source]&campaign=[campaign]&content=[content]

Debugging

As the response for this URL has to contain a 1x1 pixel gif, validation messages are available via HTTP response headers prefixed with CUBED-

Third-Party Cookies

To track impressions, third-party cookies are used. In CUBED Attribution this is achieved by generating a random Sync ID for every impression and storing this into a third-party cookie.

When the user returns to the site. This Sync ID is used to join the two visitors together.
