Ask Why do digital marketing courses teach things that simply do not work when you actually try them?

[Meridian]

Many digital marketing courses are created from methods that worked years ago but no longer bring the same results today. Online platforms change often, and a strategy that once brought traffic or sales can become much less effective. Some courses also focus on simple lessons because real marketing is harder to explain and depends on many factors. Things like competition, budget, timing, and audience behavior all affect results. In your opinion, should marketing courses spend more time teaching how to adapt instead of teaching fixed methods?
