A catfish ad unit is a 955 x 75 pixel banner that is anchored over the webpage at the bottom of the browser window. The catfish unit remains fixed and above the fold as the user scrolls the page, guaranteeing 100% viewable impressions. The ad includes its own close button that removes it by choice, ensuring a non-invasive, yet effective user experience.
