LinkedIn Ad Preview

LinkedIn Sponsored Content ads are native ads that appear directly in the LinkedIn feed alongside organic posts. They include an intro text, a visual (image or video), a headline, a description, and a call-to-action button. They are labeled "Sponsored" so users know they are paid placements. These are the most common ad format for B2B marketers on LinkedIn.

LinkedIn Sponsored Content has three key character limits: Intro text — 150 characters (although the platform allows up to 600, only about 150 characters show before a "see more" link truncates the text on most devices). Headline — 70 characters. Description — 100 characters. Staying within these limits ensures your full message is visible without truncation and delivers a clean in-feed experience.

The recommended image size for LinkedIn Sponsored Content is 1200×627 pixels (1.91:1 aspect ratio). This is the standard horizontal format and displays best across desktop and mobile feeds. LinkedIn also supports 1200×1200 px (1:1 square). Use a high-quality JPEG or PNG. LinkedIn recommends keeping the file size under 5 MB.

Choose a CTA that matches your campaign objective. Learn More works for awareness and consideration campaigns. Download suits gated content like whitepapers. Request Demo and Get Quote drive high-intent B2B leads. Sign Up and Register are best for events or free trials. Always test at least two CTA variants — small wording changes can meaningfully shift click-through rates.

In LinkedIn Campaign Manager, duplicate your ad within the same campaign and change one variable at a time — headline, intro text, image, or CTA. Run both variants simultaneously with equal budget. LinkedIn will report impressions, clicks, and CTR for each. Use this preview tool to review each variant in context before uploading. Aim to run tests for at least 2 weeks or until each variant has at least 1,000 impressions before drawing conclusions.
