Creative Best Practices

  • Keep the message focused and simple. Viewers should easily and immediately understand the ad’s takeaway.
  • Always provide a call to action! Give viewers a compelling reason to engage with you.
  • Encourage engagement with action-oriented buttons, but do not use the word “click.” Opt for phrases like “Visit Us,” “Apply Now,” and “Get Started Today,” which convey an inherent benefit to the user.
  • Use the same creative elements from your ads on your landing page. They should have a similar look and feel.
  • Ensure that the ad’s landing page delivers! Users should be able to easily find what the ad promises.
  • Include human presence and/or campus shots with a prominent logo.
  • Avoid ad fatigue. Make new creative as often as your budget and bandwith allow. It’s important to keep ads fresh.

Image Ratio

  • 1.91:1 (horizontal, desktop and mobile)
  • 1:1 (square, desktop and mobile)
  • 1:1.91 (vertical, mobile only)

Horizontal / Landscape

Horizontal images will deliver to both desktop and mobile.

  • Minimum: 640 x 360 pixels
  • Maximum: 7680 x 4320 pixels
  • Recommended: 1.91:1 – 1200 x 628 pixels

Square

LinkedIn recommends this aspect ratio for delivery across both desktop and mobile.

  • Minimum: 360 x 360 pixels
  • Maximum: 4320 x 4320 pixels
  • Recommended: 1:1 – 1200 x 1200 pixels

Vertical

LinkedIn recommends this aspect ratio for best performance on CTR on mobile (vertical images do not deliver to desktop). While 1:1.91 vertical images are still supported for vertical images, they will have borders added to either side of the video to fit in the image frame. To avoid borders, we recommend using a 4:5 aspect ratio.
