I'm going to build a directory, but just looking for some guidance on how specific to make it? General Directories are so saturated, I would want to get more specific. Is a Sports Directory still too general? Would you narrow it down to a specific sport? Like Football? Is Music Directory too general? Would you narrow it down to something specific, like Lyrics?
If you have a niche that is business oriented you can make some good coin getting a super narrowed niche ie: Guitar Shops or Manufacturers directory... if its a directory such as football or music ... the more specific you make it the harder it will be for you.
