Course Image and Preview Video That Convert

When a student searches for your topic, they see a grid of course cards. Each card has an image, a title, a rating, and a price. In under two seconds, they decide which ones to click.

Your course image is the first thing they notice. It has to stop the scroll, communicate what the course is about, and look professional enough to trust with their time and money.

Course Image Design Rules

Use a clear, readable title on the image. The image should contain your course’s main keyword or a shortened version of the title. When the card is small in search results, the image text is often more readable than the actual title below it.

Use high contrast. Dark text on a light background or light text on a dark background. Avoid busy backgrounds that make text hard to read at small sizes.

Show a face when possible. Images with a person’s face (the instructor, smiling, looking at the camera) get more clicks than abstract graphics. Students connect with people. If you’re comfortable showing your face, do it.

Keep it simple. One main element (your photo, a relevant icon, or a simple illustration), the course keyword, and maybe a subtle design accent. Don’t try to cram your entire value proposition into the image.

Use the correct dimensions. Udemy recommends 750x422 pixels (16:9 aspect ratio). Skillshare uses 1600x900 pixels. Check the current requirements for your target platform before designing.

Design tools: Canva has marketplace course image templates. Use one. It’ll save you time and look professional.

The Preview Video

Most marketplaces let you add a preview video — a free video that anyone can watch without enrolling. This is your strongest conversion tool.

Students who watch the preview are significantly more likely to enroll than those who don’t. The preview is your chance to show them what they’ll get, prove your teaching quality, and create enough curiosity to click “Enroll.”

Preview video structure (3-5 minutes):

0:00-0:15 — The hook. State the problem and promise a solution. “If you’ve ever struggled with [specific problem], in the next three minutes I’ll show you exactly how to [specific outcome].”

0:15-1:00 — Teach one useful thing. Not an overview. Not a pitch. Teach one specific technique, concept, or tip that delivers real value. The student should think “that was helpful” before you even ask them to enroll.

1:00-2:00 — Show the bigger picture. “What I just showed you is one piece of a complete system. In this course, you’ll learn [3-5 specific outcomes]. By the end, you’ll be able to [big promise].”

2:00-3:00 — Social proof and credibility. Briefly mention your experience, student results, or why you’re qualified to teach this. One or two sentences. Don’t oversell.

3:00-3:30 — The enrollment push. “Click ‘Enroll Now’ and I’ll see you in the first lesson.” Simple, direct, clear.

What to Avoid in Previews

Don’t make it an ad. Students clicked to learn something, not to watch a commercial. Teach first, pitch second.

Don’t make it a trailer. A montage of clips with music doesn’t prove you can teach. It proves you can edit video. Show actual teaching.

Don’t go over 5 minutes. The preview is a taste, not a full meal. Long previews lose viewers before the CTA.

Don’t use the first lesson as your preview. Your first lesson is a welcome or introduction. It’s not compelling to someone who hasn’t committed yet. Create a dedicated preview video designed to convert.

The Image-Title-Preview Combo

These three elements work together:

1. Image catches attention and communicates the topic
2. Title tells them what they’ll learn and who it’s for
3. Preview proves you can teach and shows what’s possible

A student who clicks your image reads your title, watches your preview, and enrolls. Each step has to earn the next one.

Your Task

Design your course image using Canva or your preferred tool. Then script a 3-minute preview video using the structure above. Don’t record it yet — just write the script. You’ll record it after the course is finished.
