The online course market is large enough that almost any subject has fifteen competing options, most of them presented with near-identical marketing pages. The differences that actually matter are rarely on the sales page — they’re in policy details and instructor background you have to dig for.
Check who actually teaches it
Search the instructor’s name outside the platform. Are they currently working in the field, or did they stop practicing years ago and pivot to teaching full-time? Neither is automatically disqualifying, but a platform that hides instructor backgrounds behind a first name and a stock photo is a signal to look elsewhere.
Ask when the content was last updated
Fast-moving fields — software, design tools, marketing platforms — go stale within 12-18 months. A course with no visible update history covering a tool that changed its interface two versions ago is teaching you to use software that no longer exists. Look for a stated revision schedule or a visible "last updated" date.
Read the refund policy before you need it
A specific, time-bound refund window (say, 14 days, with a completion-percentage cap) is a good sign — it means the platform is confident enough in the product to offer real terms. Vague language like "refunds considered case by case" usually means they aren’t.
Look for a completion path, not just content
Video count isn’t the same as a curriculum. Good platforms structure courses around a project or outcome you build toward, not just a stack of lectures. If you can’t find a clear answer to "what will I be able to do when I finish this," that’s the biggest warning sign of all.
The five-minute test
Before paying, spend five minutes trying to find: the instructor’s current job, the last content update date, the refund policy, and one specific thing you’ll be able to build or do afterward. If a platform makes any of those hard to find, treat that difficulty itself as the answer.
