Optimal Video Length by Objective

Campaign Goal	Recommended Length
Brand awareness	15-30 seconds
Consideration	30-60 seconds
Conversion	30 seconds – 2 minutes

According to LinkedIn's official guidance, the sweet spot for high completion rates is 15-30 seconds. For brand awareness campaigns, aim for under 15 seconds. Product demos can stretch toward 30 seconds but should front-load the key message.

The First 3 Seconds Rule

Your first three seconds determine whether viewers keep watching or scroll past:

• Hook immediately: Open with your most compelling visual or statement
• Show brand early: Display your logo or product within the first three seconds
• Skip slow intros: No animated logos, fade-ins, or setup—get to the point

Research shows that viewer attention drops significantly after the first few seconds, making the opening critical for both engagement and message delivery.

Creative Best Practices

Strong creative separates high-performing video ads from wasted budget.

Visual Elements

Design for mobile first Most LinkedIn video views happen on mobile devices. Design accordingly:

• Use large, readable text overlays
• Keep important elements in the center frame
• Test how your video appears on smaller screens

Include captions 80% of LinkedIn users watch videos without sound. Always include:

• High-contrast caption text
• Mobile-readable font sizes
• Key message delivery through text, not just audio

Show people Videos featuring real people consistently outperform abstract graphics:

• Founder or executive messages build trust
• Customer testimonials provide social proof
• Team footage humanizes your brand

Content Types That Work

1. Thought Leadership Expert insights from executives or industry specialists:

• 30-60 seconds of focused advice
• Strong opening statement
• Clear takeaway or call-to-action

2. Product Demonstrations Show your product solving a real problem:

• Focus on one key feature or workflow
• Use screen recordings with voiceover
• End with clear next steps

3. Customer Testimonials Let customers tell your story:

• Authentic, unscripted responses
• Specific results and metrics when possible
• Professional but not overly polished

4. Brand Stories Company culture and values content:

• Behind-the-scenes footage
• Team member spotlights
• Mission and impact stories

What to Avoid

• Overly long intros: Get to value immediately
• Silent videos without captions: You'll lose most viewers
• Poor audio quality: Invest in decent microphones
• Landscape-only: Mobile viewers see tiny videos
• Complex messaging: One clear point per video

Video Production Tips

You don't need Hollywood budgets, but production quality matters.

Equipment Basics

Minimum viable setup:

• Smartphone camera (iPhone or recent Android)
• Natural lighting or one softbox light
• External microphone (lavalier or USB condenser)
• Simple background (solid wall or branded backdrop)

Professional setup:

• DSLR or mirrorless camera
• Three-point lighting
• Professional audio recording
• Teleprompter for scripted content

Editing Priorities

1. Tight pacing: Cut anything that doesn't add value
2. Captions: Add burnt-in captions, not relying on auto-generated
3. Branding: Consistent intro/outro with logo
4. Sound mixing: Balance voice, music, and sound effects

DIY vs. Professional Production

Scenario	Recommended Approach
Founder updates	DIY with good audio
Product demos	Professional or high-quality DIY
Customer testimonials	Professional capture, authentic style
Brand campaigns	Professional production
Thought leadership	Can be DIY with proper setup

Performance Optimization

Monitor these metrics and optimize based on data.

Key Performance Indicators

Metric	What It Tells You	Benchmark
Video completion rate	Content engagement	25-35% for 30-sec ads
View rate	Creative appeal	15-25%
Click-through rate	Call-to-action strength	0.5-1.0%
Cost per view	Budget efficiency	$0.06-$0.15
Cost per completion	Content value	$0.15-$0.30

A/B Testing Framework

Test these elements in priority order:

1. Opening hook: Different first 3 seconds
2. Video length: 15 sec vs. 30 sec vs. 60 sec
3. Aspect ratio: Square vs. landscape vs. vertical
4. CTA placement: End card vs. throughout vs. verbal only
5. Style: Talking head vs. animated vs. footage

Optimization Tips

For low completion rates:

• Shorten video length
• Strengthen opening hook
• Add captions if missing

For low CTR:

• Test different CTAs
• Add end cards with clear next steps
• Ensure landing page matches video promise

For high CPV:

• Broaden targeting slightly
• Test different aspect ratios for mobile
• Refresh creative if running for 2+ weeks

Frequently Asked Questions

What is the best video length for LinkedIn ads?

LinkedIn recommends 15-30 seconds for most video ads, which is the sweet spot for high completion rates. Brand awareness campaigns perform best at under 15 seconds, while product demos and consideration-stage content can extend to 30-60 seconds. Always front-load your key message in the first 3 seconds.

Do LinkedIn video ads need captions?

Yes—captions are essential because most LinkedIn users watch videos without sound. Include high-contrast, mobile-readable captions for all video ads. Burnt-in captions (embedded in the video) work better than relying on LinkedIn's auto-generated captions, which can have accuracy issues.

What aspect ratio works best for LinkedIn video ads?

Square (1:1) and vertical (4:5) formats perform best on mobile, where most views occur. Square videos at 1080 x 1080 pixels maximize feed real estate. Use 16:9 landscape only if your audience is primarily desktop-based. Test multiple aspect ratios to find what works for your specific audience.
