I would like some advice or peoples opinions. I'm starting a online directory for a particular niche and would like to know how small or big it should be because of SEO. For example having a domain: homeimprovements.com and within that directory having plumber, carpenter, electrician etc or having a domain http://www.findaplumber. org and just focusing on plumbing.
There are a few reason why I would choose the first example:
-Better value for the customer as a lot of times they may need multiple services
-I know the sub niche are in need of a directory for business promotion so I can kind of kill two birds with one stone.
