When Should a Content Writer Split One Guide into Several Articles?

I’m planning a detailed guide that covers several closely related questions. It would be convenient to keep everything in one place, but I’m concerned that readers looking for one specific answer may have to scroll through too much material.

How do you decide when to divide a broad guide into separate articles? I’m especially interested in balancing reader experience with search intent overlap—I don’t want several pages that compete for the same queries or a single page that feels unfocused.
