You can tell which content style your niche needs by looking at how much information people require before making a decision. Long-form content works better for products that need clear explanations, like software tools, online programs, or items with many features. Short-form content fits simple products where people mostly need a quick idea before buying. Testing can help as well. Posting one long review and one short video on the same topic shows which one gets more clicks or comments. Studying the questions people ask in your niche also gives clues about how much detail they expect. Do you think long content still plays a strong role in affiliate selling today?
