CREATIVE BEST PRACTICES:

• Design mobile-first (320x50px). Do not simply shrink your leaderboard creative.
• Less text is better. Branding and call to action should be the whole ad.
• Make sure all text is legible.
• Don't just link to your home page — make an offer or call to action so users won't just make a mental note to visit your site later.
• Use color to make your ad stand out — but not so much as to make them more difficult to read.
• If the background of the ad is a light color (e.g., white, light gray), make sure to put a border around it — but a colorful background is preferred.
• The smaller the file size, the faster the ad will load.
