It's better for beginners to focus on one platform until they understand how it works and see some progress. Each platform has its own style, audience, and way of working. For example, learning how to write good posts on Facebook is very different from making videos on YouTube. Switching too early can cause confusion and slow growth. Most people need at least a few months to learn what content gets engagement, how the audience reacts, and which products perform better. Once you can create content easily and get steady clicks or sales, then trying another platform makes more sense. How long do you think someone should stay on one platform before moving to the next?
