A 1×1 pixel image that is inserted on a specific page that is usually after a user completes some type of action. When the image loads it triggers code on the tracking server to attribute the user action to the proper party. This was the original implementation of tracking code in the early days of online marketing and is still used today.
Image pixels are usually less accurate than modern JavaScript or postback pixels due to the older technology and limitations of image tags. Whenever possible we suggest using a postback pixel or JavaScript pixel for the most accurate results.
