Best Practices for LinkedIn Ads

To maximize the effectiveness of your LinkedIn advertising campaigns, consider the following best practices:

• Craft Compelling Ad Copy: Clearly articulate the value proposition, focusing on how your product or service addresses specific pain points of your target audience.​
• Design Visually Engaging Creatives: Use high-quality images or videos that resonate with professionals, ensuring they align with your brand identity.​LinkedIn
• Implement Strong Calls-to-Action (CTAs): Use action-oriented language that encourages immediate responses, such as “Download Now” or “Schedule a Demo.”​
• Optimize for Mobile: Given the significant mobile usage among LinkedIn users, ensure your ads are mobile-friendly. Use concise headlines, legible fonts, and appropriately sized images to enhance readability on smaller screens. Place CTAs prominently to facilitate easy interaction.​
• Leverage A/B Testing: Regularly test different elements of your ads, including headlines, images, and CTAs, to identify what resonates best with your audience. For instance, experiment with question-based headlines versus statement headlines to see which yields higher engagement.

Mobile Optimization Tips for LinkedIn Ads

With 57%+ of LinkedIn traffic coming from mobile devices, optimizing your ads for mobile users is crucial to ensure a seamless experience and maximize conversions.

Here are specific recommendations to improve mobile performance:

Recommended Image Sizes

• Single Image Ads: 1200 x 627 pixels (1.91:1 aspect ratio)
• Carousel Ads: 1080 x 1080 pixels (square, 1:1 ratio)
• Video Ads:
  • Landscape: 1920 x 1080 (16:9)
  • Square: 1080 x 1080 (1:1) – often performs better on mobile
  • Vertical: 1080 x 1920 (4:5 or 9:16) – ideal for a mobile-first approach

Character Limits for Mobile Ad Copy

• Headline: Max 70 characters (but aim for under 50 for mobile readability)
• Introductory text: Visible limit ~140 characters before “See more”
• CTA buttons: Choose from predefined CTAs (e.g., “Download,” “Learn more”) that are short and mobile-friendly

Mobile CTA Best Practices

• Place CTAs high in the visual hierarchy—users should see the action immediately
• Use strong, concise language like “Start Free Trial,” “Watch Demo,” or “Claim Offer”
• Make sure any linked landing page is fast-loading and fully responsive on all screen sizes

💡 Pro Tip: Always preview your ads in mobile format within LinkedIn Campaign Manager to ensure proper rendering.

A/B Testing on LinkedIn: What to Test and How

Running structured A/B tests (also known as split tests) is essential for identifying what drives the best results. LinkedIn Campaign Manager doesn’t have a native A/B testing tool, but you can set up manual split tests by creating multiple campaigns or ad variations.

What to A/B Test

Here are specific elements to test and compare:

Element	Variant A	Variant B
Headline	“Download Our Free Guide”	“Struggling with Lead Gen? Get Help”
Intro Text	Short, direct	Longer, story-based intro
CTA	“Download Now”	“Get Your Copy”
Image	Product screenshot	Abstract illustration
Video Length	15 seconds	45 seconds
Ad Format	Single Image	Carousel
Targeting Criteria	Job title only	Job title + skill filter

How to Structure Your A/B Tests

1. Test one variable at a time. For example, if you’re testing two CTAs, keep the headline, image, and audience identical.
2. Create separate campaigns or ad sets for each variation.
3. Run them simultaneously to avoid skewed results due to timing.
4. Run for at least 7–10 days, or until each version gathers statistically significant data.
5. Evaluate metrics such as CTR, CPL, and conversion rates to determine a winner.

💡 Pro Tip: Use LinkedIn’s “Duplicate” feature to quickly clone campaigns or ads while modifying just one variable for a clean test.
