In the main menu, click Audiences > Segments.
Hold the cursor over the segment row and click Get Pixel.
The page view tracking tag, which tracks desktop and mobile visitors to a webpage, is labeled “Desktop or mobile websites.”
(Custom segments only) The impression tracking tag, which tracks users exposed to an ad unit on desktop, mobile, or CTV devices, is labeled “Desktop or mobile ads.”
(As needed) Copy the relevant tag(s) and provide the tags to the advertiser or website contact for deployment.
Once a tracking tag is implemented, you can use the segment in the audience targets or exclusions for any placement.
