Google Display Ads Best Practices
Keep File Sizes Small
Google recommends keeping image file sizes under 150 KB for standard formats. Smaller files load faster, improving user experience and ad performance.
Use High-Quality Images
Despite size limits, image quality matters. Use crisp, professional imagery that represents your brand well, even at smaller dimensions.
Test Multiple Sizes
Different ad sizes perform better on different sites. Upload multiple formats to maximize reach and impressions across the Display Network.
Clear Call-to-Action
Include a prominent CTA button or text. Display ads have limited space, so make your message clear and actionable.
