Image Ad
Definition
A Reddit ad format consisting of a single static image paired with a headline, optional body text, and a call-to-action link. One of the most common and versatile ad formats on the platform.
Context
Reddit image ads support standard social media image specifications. The recommended aspect ratio for in-feed image ads is 4:5 (portrait) for mobile and 1:1 (square) for broad compatibility. High-contrast images with minimal text tend to perform better in feed environments where users scroll quickly.
Relevance to Reddit
Image ads work best for simple, visually clear messages — a specific offer, a compelling product visual, or a striking data point. For more complex messages requiring context or explanation, Free-Form or text-based Promoted Posts typically outperform single images. Test multiple image variations with different visual approaches rather than iterating on copy alone.
