Facebook Ad Best Practices
Design for mobile first
Over 98% of Facebook users access the platform via mobile. Use the 4:5 aspect ratio for Feed to maximize screen real estate on phones.
Assume sound is off
85% of Facebook videos are watched without sound. Add captions or text overlays to convey your message visually.
Capture attention in 3 seconds
Users scroll quickly. Your ad needs to hook viewers in the first 3 seconds or they will scroll past.
Use contrasting colors
Facebook's interface is predominantly blue and white. Use warm colors like orange, red, or yellow to stand out in the feed.
