Treat algorithm claims with care
Nobody outside a platform knows precisely how its ranking works, and platforms change it frequently. Good courses describe what is documented, what is widely observed and what is guesswork, and label the difference. A course teaching an infallible method for reach is teaching a theory about a system it cannot see.
Check the date harder than usual
A social media course from two years ago may reference formats that no longer exist, features that were withdrawn and a platform that has since renamed itself. Principles about audience, consistency and format hold up; specifics rarely do. Where a provider publishes a last-updated date we record it, and where they do not, the listing shows only when we checked the page.
Separate organic from paid
Growing an audience and buying attention are different disciplines with different budgets and different skills. Courses often cover both thinly. Decide which you are actually doing, and if it is paid, expect the course to require an advertising budget to practise with.
Pick the platform your audience is on
Every platform rewards a different format and a different rhythm, and a course is normally specific to one even when the title is generic. Learning the wrong one well is a common and expensive mistake. Each listing names the platform where the provider states it.
Be sceptical of follower and income claims
Screenshots of large accounts prove that a large account exists, not that a method produced it. Timing, existing audience and luck are invisible in a case study and often decisive. A course can teach craft and consistency honestly, and that is a smaller claim than most of this field makes.
