Improved Validation & Error Handling for Google & LinkedIn Ad Campaigns

/in
We’ve improved validation and error handling for

Google and LinkedIn campaigns

in Ad Manager to make campaign publishing more reliable and easier to troubleshoot.

Google-specific improvements

  • Added a pre-publish validation flow covering campaign fields, advertising requirements, and Google platform requirements.
  • Improved validation for

    Demand Gen campaigns

    , including required images, logos, videos, headlines, descriptions, long headlines, and carousel assets.

  • Improved messaging for missing Website URLs and duplicate creative content.

LinkedIn-specific improvements

  • Improved validation across

    LinkedIn carousel cards

    , including required headlines and URLs.

  • Errors now provide better context about the specific carousel card requiring attention.
  1. Configure the campaign, ad groups/ad sets, and ads as usual.

For

Google campaigns

, an additional validation flow checks campaign fields, advertising requirements, and platform requirements before submission.

For

LinkedIn campaigns

, the improved experience focuses on UI validation and clearer identification of issues across creatives and carousel cards.

Previously, some validation issues appeared only after a publishing attempt or surfaced one at a time, resulting in repeated fix-and-retry cycles.

These improvements help users:

  1. Google campaigns now use the expanded pre-publish validation flow.
  2. LinkedIn continues to use its existing publishing flow, with improvements focused on UI validation and error handling.
  3. Additional platform-level errors or policy rejections may still be returned by Google or LinkedIn after submission.
