"It depends" is honest, but it is not helpful on its own. What you want to do is explain what it depends on, using clear examples. For instance, if someone asks which email marketing tool is the best, you can say something like: if you are just starting out and have no budget, this one works well, but if you have a growing list and need more features, this other one is better. Breaking it down by situation gives readers a real answer they can use. People appreciate when you actually help them decide rather than leaving them more confused. How do you usually handle this in your own content?
