Boost Engagement: Best Practices for Facebook and TikTok Video Advertising

The engagement challenge on social media in 2025

Facebook and TikTok remain the dominant platforms for video advertising, but the competition for attention has never been fiercer. Users scroll past hundreds of ads daily — only the most engaging ones get noticed, watched, and acted upon.

AI-powered video creation tools are changing the game. Instead of spending weeks producing a single ad variation, marketers can now generate dozens of AI-crafted video ads in hours, test them simultaneously, and double down on what works.

Start with Domer's AI video generator to produce platform-optimized video ads at scale.

Platform-specific strategies

TikTok advertising

TikTok's algorithm rewards native-looking content. Your ads should feel like organic TikTok posts, not traditional commercials.

• Vertical format (9:16): Full-screen immersion is non-negotiable
• First 3 seconds: Hook viewers immediately — TikTok users swipe fast
• Trend-jacking: Align your creative with trending sounds and formats
• Text overlays: Bold, dynamic captions keep users watching even without sound

Facebook advertising

Facebook's audience is broader and more diverse. Your creative strategy needs to account for different age groups and viewing contexts.

• Square (1:1) and vertical (4:5) formats perform best in-feed
• Storytelling arc: Facebook users respond to narrative — even in 15 seconds
• Subtitles are mandatory: 85% of Facebook videos are watched without sound
• Clear CTAs: Tell viewers exactly what to do next

AI-powered creative optimization

Rapid variation testing

Instead of guessing what works, let AI generate multiple variations of your ad with different:

• Visual styles (realistic, animated, mixed media)
• Color schemes
• Text overlay placements
• Opening hooks

Using Domer's text-to-video tools, you can create variations from written briefs in minutes rather than days.

Dynamic creative elements

AI can personalize ad elements based on audience segments — different thumbnails, different product shots, different messaging for different demographics.

Performance prediction

Advanced AI models analyze your creative before launch and predict likely engagement rates, helping you prioritize which variations to push budget toward.

Measuring what matters

Engagement isn't just likes and shares. Focus on metrics that drive business results:

Metric	What it tells you
Thumb stop rate	How effectively your hook stops the scroll
View-through rate	How compelling your full video is
CTR	How well your CTA converts interest to action
CPA	Your actual cost per desired action

Common mistakes to avoid

1. Over-producing: TikTok users distrust polished ads — authentic beats perfect
2. Ignoring sound-off viewing: Always design for both muted and unmuted experiences
3. Weak hooks: If you don't earn attention in 2 seconds, the rest doesn't matter
4. One-size-fits-all creative: Facebook and TikTok demand different approaches

Use Domer's AI image generator to create eye-catching thumbnails and visual assets that stop the scroll.

Your action plan

1. Audit your current creative: Which ads are performing? Why?
2. Build a testing framework: Plan 5-10 variations per campaign
3. Leverage AI tools: Use Domer's platform for rapid production
4. Analyze and iterate weekly: Kill losing variations, scale winners
5. Document learnings: Build a playbook of what works for your audience
