Social Media Video Ads for B2B: Best Platforms, Formats, and Strategies for 2025

B2B buyers don’t just research through whitepapers and webinars anymore.

They scroll LinkedIn, skim Instagram Reels, and watch YouTube Shorts between meetings.

If your brand isn’t investing in social media video ads, you’re missing where real engagement happens in 2025.

B2B video production needs to be adapted for social-first consumption—short, sharp, mobile-optimized, and deeply relevant.

Let’s dive into the best platforms, formats, and practices to make social media video advertising a real growth lever for your brand.

Why Social Media Video Ads Work in B2B

✔ They meet buyers where they are: Mobile-first, scroll-heavy habits dominate professional audiences.
✔ They simplify complex ideas quickly: Short-form videos can explain value props in 15 to 60 seconds.
✔ They boost brand recall: Motion, audio, and storytelling make your brand stick.
✔ They drive conversions: Strategic CTAs inside video ads move viewers into action faster.

B2B buyers behave more like consumers than ever. Your video production strategy needs to reflect that reality.

Best Platforms for B2B Social Media Video Ads

Not all platforms perform equally for B2B. Focus your video ad strategy on:

✔ LinkedIn: Best for targeting by industry, job title, and company size. Great for both awareness and lead gen.
✔ YouTube: Owned by Google. Perfect for long-tail targeting, retargeting, and high-intent video searches.
✔ Instagram: Surprisingly powerful for top-of-funnel brand engagement, especially using Reels.
✔ Facebook: Still valuable for retargeting campaigns and remarketing to warm B2B audiences.
✔ TikTok (Selective): For tech-savvy, creative industries, short B2B educational content can work if the tone is right.

Choosing the right distribution channel is just as critical as producing strong video assets.
