YouTube is more than an entertainment site, even though many people watch for fun. It is a search platform where users look for answers and guides. Businesses can post helpful videos that solve problems or explain products. These videos can bring traffic for years if the topic stays useful. Comments also allow direct conversation with viewers. Consistency matters more than viral success on YouTube. One helpful video can perform better than many random posts. The platform rewards titles and content. How should businesses balance teaching and promotion on YouTube?
