Offering a free trial is one of the strongest conversion strategies for SaaS companies. According to research from Totango, around 62% of SaaS companies gain more than half of their new customers through free trials. But the key challenge isn’t just getting people to sign up — it’s finding the right ad formats that persuade users to take action.
Overview of Facebook ad formats most effective for driving SaaS free trials
The right format can highlight value, showcase features, and reduce sign-up friction. On Facebook, some formats consistently outperform others when it comes to trial offers.
1. Video Ads: Demonstrating Value Quickly
Video ads are ideal for SaaS free trials because they show, not just tell. Instead of relying on static text, you can highlight key features in action. A Wyzowl study found that 84% of people were convinced to buy a product or service after watching a brand’s video, proving how powerful this format can be.
Tips for SaaS video ads:
-
Keep them under 30 seconds.
-
Show real use cases rather than abstract features.
-
End with a clear call to action like “Start Your Free Trial Today.”
2. Carousel Ads: Perfect for Highlighting Features
SaaS platforms often solve multiple pain points. Carousel ads let you highlight different features within one ad. Each card can represent a unique benefit — for example, automation, analytics, or integrations.
Carousel ads are especially effective if your SaaS targets multiple types of users. You can personalize the cards to show value to different roles, like marketers, managers, or developers.
3. Lead Ads: Frictionless Sign-Ups
One of the biggest obstacles to free trial conversions is friction in the sign-up process. Facebook Lead Ads reduce this by keeping users on-platform. Instead of clicking out to a landing page, they can sign up directly in the ad.
For SaaS free trials, this works well when paired with strong targeting. Imagine targeting decision-makers and letting them request access in just two clicks. That kind of simplicity can lift trial sign-ups significantly.
4. Collection Ads: A Mini-Landing Page
Collection ads work like a hybrid between video and carousel formats. They start with a cover image or video, then expand to show multiple products or features. For SaaS, you can use collection ads as a visual landing page, showing how your tool helps in different scenarios.
This format also works well on mobile, which is critical since over 94% of Facebook ad revenue comes from mobile devices. If your free trial ad isn’t mobile-first, you’re already losing most of your potential audience.
5. Retargeting Ads: Converting Warm Leads

Not all trial conversions happen on the first touch. Retargeting ads allow you to remind users who visited your site but didn’t complete the trial sign-up. You can use short, snappy creatives like “Still thinking about it? Start your free trial now” to nudge them back.
Adding social proof here — reviews, testimonials, or quick metrics — can also boost credibility. Retargeting ensures you don’t lose people who were already interested.
Final Thoughts
SaaS free trials depend heavily on the ad formats you choose. Video ads tell a story, carousels highlight features, lead ads remove friction, collection ads create an immersive experience, and retargeting ads close the loop. By testing and combining these formats, you’ll find the perfect mix to drive free trial conversions.
