You published the course. You waited a week. Six enrollments — three of which you recognize as people you personally told about it.
Zero to 100 students is genuinely the hardest stretch of selling a course online. You have no reviews to show skeptical buyers, no algorithm momentum working in your favor, and no proof that the thing you spent months building is something strangers will pay for.
This guide is specifically about that stretch. Not about scaling to 10,000 students — about getting past zero in a way that builds something real.
Why the first 100 is different from everything after
Once a course has 20+ reviews and a few hundred students, the Udemy algorithm starts surfacing it organically. More reviews lead to more visibility, more visibility leads to more enrollments, and the loop accelerates. Before that point, the loop doesn't exist — you have to manually create every enrollment.
The goal of the first 100 isn't revenue. It's social proof. Getting 15–20 honest reviews is worth more at this stage than the revenue from 15–20 sales, because those reviews are what unlock the organic growth that everything after depends on.
What actually works before you have reviews
Fix the title before anything else
If your course title doesn't contain the exact phrase your target student would type into Udemy search, you won't get organic traffic regardless of what else you do. Check the top 10 courses in your topic — what words appear in every title? Those words should be in yours, and they should appear early.
Give away 30–50 enrollment coupons to get initial reviews
Reach out to people in communities related to your topic — forums, Reddit threads, Facebook groups, Discord servers — and offer free access in exchange for an honest review. Be transparent about it. Most people in topic-specific communities are genuinely willing to give feedback on something relevant to their interest. Udemy allows coupon-based free enrollments. 15 honest reviews changes how the algorithm treats your course.
Post in one specific community before you launch
Pick one community where your target student actually hangs out. Post something genuinely useful — a tip, a short tutorial, a resource. Mention the course as context, not as the point of the post. Contributed value is what makes the community mention feel natural rather than spammy. One community done well beats ten communities done poorly.
Email the people who already know you
Former colleagues, people who've worked with you, students from any previous teaching — message them directly. Not a mass email, an individual message. Tell them what the course covers and ask if it's something they'd find useful. The conversion rate on a genuine personal message from someone they know is dramatically higher than any other channel.
Use Udemy's promotional tools as soon as they're available
Udemy lets you submit your course to their promotional deals once it hits certain thresholds. These deals send traffic at $10–$13 effective revenue per enrollment. It's not high — but 50 enrollments from a Udemy deal is 50 real students, and some percentage will leave reviews.
What doesn't work (and wastes weeks)
- ✕Posting launch announcements on social media to a small existing following (reach is too limited)
- ✕Waiting for Udemy to surface your course organically before you have reviews
- ✕Spending heavily on paid ads before you know your conversion rate
- ✕Announcing on multiple platforms at once without going deep on any of them
Start with a course students actually want to finish
All of this assumes the course is structured in a way that students actually complete. A course with a 5% completion rate won't get positive reviews even from students who liked the topic — they just don't finish it.
CourseKit generates a full module-by-module curriculum with clear learning objectives per lesson and a final project structure — in under 5 minutes. Getting the structure right before you record prevents the most common reasons students drop off.

How long does it take to get 100 students on Udemy?
It varies widely depending on the topic and how actively you promote it. Some courses reach 100 students in a few weeks through a combination of Udemy's organic search and early promotion. Others take months. The most reliable variable is whether your course title matches what students are actually searching for — that determines whether you get discovered at all.
Do you need social media followers to sell an online course?
No — and this misconception stops many potential instructors from starting. Most Udemy instructors with successful courses had very small audiences when they launched. Marketplace platforms like Udemy do the distribution. What you need is a course on a topic with real search demand, a title that matches that demand, and enough early reviews to build credibility.
Should I launch on Udemy or my own platform?
For your first course, Udemy. It has built-in traffic, doesn't require you to build your own email list, and costs nothing upfront. The tradeoff is that you don't own the relationship with students. Once you have reviews and social proof, moving some courses to your own platform (Teachable, Gumroad) for better margins makes sense. Start where the distribution exists.
How much should I charge for my first online course?
Udemy controls discounting heavily — most students buy during promotions at $10–$20. The list price you set affects how deep the discount looks, but the effective revenue per student is often in the $5–$12 range through Udemy's organic channels. Getting your first 20–30 reviews matters more than optimizing the price point right now.
Is it worth doing a free launch to get initial reviews?
Giving out coupon codes to friends, colleagues, or a small community in exchange for honest reviews is a common and effective strategy. Udemy's terms allow this as long as you don't explicitly pay for reviews. 10–15 early reviews can move you from invisible to credible in search results. It's often worth giving away 30–50 enrollments to get there.
