Pixel Tracking is used to signal events to a Tracking Service in the web environments where Javascript is disabled. Fortunately, in most web environments, Javascript IS enabled, so the preferred methodology is to use Javascript Trackers instead of Pixel Trackers. In the in-app world, tracking is usually achieved through API tracking integrations.
Pixel tracking can be used to track any important web events: impression events (when ads are shown to a user), click events (when ads are clicked on, or when the user lands in one of the advertiser’s properties through an outbound link from an ad or a link from another site, a clickthru from an influencer mention or affiliate link, etc..) and conversion events (when the user makes a purchase, or completes a lead gen form, etc…)”
