The dirty secret of the online course industry is that most courses have completion rates under 15%.
Students buy courses with genuine enthusiasm. They log in once or twice. Then life gets in the way, motivation fades, and the course sits untouched in their library forever. The creator gets the revenue but not the testimonials, case studies, or referrals that come from students who actually complete the program and get results.
Community changes this equation.
When a student joins a course and finds a community of people working through the same material, sharing wins, asking questions, and holding each other accountable, completion rates climb dramatically. Engagement extends beyond the core course content. Students stick around because of the relationships they are building, not just the curriculum they are consuming.
The platform you use to host that community matters. It affects whether students actually show up daily or whether the community becomes a ghost town within a few weeks of launch.
I have spent significant time in and building communities across all five platforms on this list. Here is what I found.

Why Most Online Communities Fail (And How to Avoid It)
The majority of online communities built by course creators fail not because the content is poor but because the platform is the wrong fit for how they want to engage with their audience.
The three most common failure modes are:
1. The ghost town problem A creator launches a community with excitement. Early members are active. Then posting gradually declines until nobody posts at all. The community still exists but has become a graveyard that embarrasses the creator when new students see it.
The solution is a platform with built-in engagement mechanics. Skool's gamification system specifically addresses this because it gives members a reason to show up beyond intrinsic motivation alone. Points, levels, and leaderboards create daily engagement habits even in the absence of new content from the creator.
2. The wrong platform for the audience Some audiences thrive on forum-style discussion. Others prefer a more intimate group chat experience. Course creators who choose a community platform without considering how their specific audience prefers to communicate often end up with low engagement regardless of how good the platform is.
Before choosing a platform, survey your audience or test with a small group. Ask where they already spend time in communities online. Match the platform structure to their existing behavior patterns rather than trying to train them into a new one.
3. The disconnected experience problem When a community lives on a completely separate platform from the course content, students have to consciously choose to visit the community in addition to the course. Each additional login and context switch reduces engagement.
Skool solves this by integrating course and community in the same experience. GoHighLevel solves it by connecting community, course, and all communication channels in one system. The less friction between the learning content and the community interaction, the higher the engagement will be.
The Testimonials-Community Flywheel
One of the most powerful combinations for course creators is using Testimonial.to alongside a strong community platform like Skool.
Here is how the flywheel works:
New students join your community and start progressing through the course. The gamification and peer accountability of the community drives higher completion rates than students working alone. Students who complete the course and get results are enthusiastic community members with genuine success stories.
At this point, Testimonial.to makes it easy to capture those success stories as video testimonials with a simple, automated collection flow. Those testimonials go onto your sales page and marketing materials, making your next cohort of prospective students more confident in purchasing.
More students join. The community gets larger and more active. The peer accountability and social proof within the community increases completion rates further. More completions mean more testimonials.
The two tools reinforce each other. Testimonial.to captures the proof of value that your community is generating. That proof of value drives enrollment. Enrollment grows the community. A larger community drives more completions. The flywheel accelerates over time.
Building Your Community Launch Strategy
Even the best community platform fails without a thoughtful launch strategy. Here is a framework that works for course creators launching or relaunching a community:
Pre-launch (four to six weeks out) Build anticipation before the community opens. Use Kit.com or your email platform to warm up your list with content about the transformation your community will create. Share behind-the-scenes setup content. Create a waitlist for founding members who join at a special founding rate.
Founding member launch Open the community to waitlist members first at a founding member discount or with exclusive perks. Founding members who joined before the community was active have the strongest stake in making it succeed and often become your most engaged long-term members.
Seed the community before inviting everyone Post the first 10 to 20 discussion threads yourself before inviting your full list. Nobody wants to join an empty room. A community that already has active discussions feels welcoming from day one.
Week one: Structured engagement In the first week, run daily prompts, challenges, or Q&A sessions that create reasons for members to post. Personally welcome and respond to every new member. The engagement habits formed in the first week tend to persist.
Ongoing: Systems for consistency Build a content calendar for your community posts. Use GoHighLevel's email and SMS automation to notify members of new content and upcoming events. Use Testimonial.to to capture success stories as they emerge.
How to Choose the Right Community Platform for Your Stage
The right community platform depends significantly on where you are in your course business journey.
Just starting out (under $10K annual revenue) Kit.com on the free plan for email. Use a free Discord server or a Facebook Group for community. These are zero-cost options that let you validate your course concept and community format before investing in paid platforms.
Growing (between $10K and $50K annual revenue) Add Skool at $99/mo once your course is generating consistent revenue. The community engagement improvements Skool drives are generally worth the investment at this stage. Integrate with Kit.com or switch to GoHighLevel for marketing automation.
Scaling (over $50K annual revenue) At this stage, the ROI from a well-run community and strong testimonial system is clear. Use Skool for community, Testimonial.to for social proof collection, and GoHighLevel for the full marketing, CRM, and automation system. This combination gives you a complete course business infrastructure.
