Tips For Making Creatives
Use the right ad format. Videos are compelling but harder to produce. Static ads are simple but non-intrusive. Create different campaigns with different ad types and see which ones perform better. What ad formats does Chartboost offer?
Grab their attention with unique, striking images. Simple gameplay screenshots aren't enough! Show off your weird characters or magical landscapes in ways that set your app apart from the rest.
Use a memorable tagline that introduces your app's story or personality, such as Twenty planets one war, Hundreds of mind-slapping puzzles to make you doubt reality, or Stop taking sass from this ninja!
Create a clear, engaging call to action. Don't settle for a boring Download button! Use app-specific prompts like Join the Battle, Start Your Adventure, or Get Your Free Dolphin Cannon! Make it big and bold so users know exactly where to press.
