Deep Dive into Key Formats

1. Single Image Ads

Single image ads appear directly in the LinkedIn feed, making them a staple for brand awareness, lead generation, and content promotion.

• Square (1:1) is currently one of the highest-performing choices because it takes up more vertical space on mobile devices than traditional landscape formats.
• Keep critical text and branding centered to avoid important details getting clipped by user interface elements.

2. Carousel Ads

Carousels let you showcase multiple images or swipeable cards within a single ad unit. They are fantastic for telling a step-by-step story, highlighting different product features, or breaking down complex data.

• Each card must adhere to a strict 1:1 aspect ratio (1080 x 1080 pixels).
• You can feature anywhere from 2 to 10 cards in a single carousel.

3. Video Ads

Video is a powerful medium for driving engagement and building brand trust on LinkedIn.

• Vertical video (9:16) dominates mobile feeds and typically yields higher completion rates.
• Always design with sound-off viewing in mind by incorporating captions or clear on-screen text, as many professionals watch videos on mute while browsing at work.

4. Text & Spotlight Ads

These smaller, native ad units appear on the desktop sidebar of LinkedIn. While text ads are simple and cost-effective for driving steady traffic, spotlight ads dynamically pull the user’s profile picture alongside your custom background creative for a personalized touch.

Pro-Tips for LinkedIn Ad Design

• Prioritize Mobile: Over 60% of LinkedIn traffic originates from mobile devices. Always preview your creatives on a phone before launching.
• Keep Text Minimal: While LinkedIn doesn’t enforce strict text-overlay percentage limits like some other platforms, clean layouts with concise headlines perform significantly better.
• Add a Clear Call to Action (CTA): Utilize LinkedIn’s built-in CTA buttons (such as “Register,” “Download,” or “Learn More”) to guide users seamlessly toward your landing page.
