LinkedIn Ad Specifications

LinkedIn Single Image Ad Specs (source)

  • Introductory text: Use up to 150 characters to avoid truncation (desktop max of 600 characters). URLs in this field that are longer than 23 characters will be converted to a short link. Important: Insert any legally required language in the introductory text.
  • Destination URL: URLs must have the "http://" "or https://" prefix. You may use up to 2,000 characters for the destination link.

Tip: Some special characters (for example: <> # % { } [ ] and others) cause errors when they're included in the query string at the end of the URL. Even if unsafe characters are accepted, they may not be supported in all browsers. If your URL generates an error, copy everything after the question mark into the URL and paste it into a URL encoder like this one: http://meyerweb.com/eric/tools/dencoder/. Then, copy your results and replace the original query string in the URL. This should resolve the issue.

  • Ad image: Upload a JPG or PNG file 5MB or smaller.
  • Headline: Use up to 70 characters to avoid truncation (200 max characters).
  • Description: Use approximately 100 characters to avoid truncation (300 max characters). This character limit may vary for ads that appear on third-party sites served through the LinkedIn Audience Network.
  • Call-to-action (optional): Choose from available CTAs.
