Programmatic Native Display

Technical Requirements:

• Image file: 1 MB Max, JPEG preferred
• Headline Character Length: 35-45 characters, 60 maximum
• Branding Text: 30 characters maximum

Thumbnail Best Practices:

• People are always preferable— even better if they’re at medium zoom from the shoulders up, or even closer.
• Avoid image clutter. Clean images with a single center of focus will help you stand out.
• Utilize eye-catching colors to attract the users’ attention. 

Title Best Practices:

Your title can be a powerful targeting tool. Call out your audience or your product when possible:
Here’s Why Parents Love This New Video Streaming Service
Here’s Why People Love This Website

Front-load titles with an eye-catching main point:
How Bad Customer Service Can Be Hurting Your Business
New Research Can Shed Light on How Bad Customer Service Can Hurt Your Business

Numbered lists can be a good way to entice a user to click:
5 New features you can find on your smartphone
A useful guide to your smart-phone's newest features

Intrigue and mystery can help draw in users: 
The real secret to happiness may surprise you
Study shows more sleep will make you happier over time

Don’t forget that titles should be capitalized, just as you would an article headline:
How Ad Tech is Transforming the Marketing Landscape
