One site or multiple sites?
I've made sites and blogs before and know a reasonable amount about the technicalities of seo and website design but I would like some planning advice for this upcoming bigger project.
I am a a professional in an un-named niche and one of the pioneers/most skilled of that niche (not to boast but to indicate the site could be popular).
I have always wanted to have a website set up where I post lessons and tutorials in that niche in media rich venues like videos, embedded audio etc. The level of knowledge I have is very broad over the subject and spans many things which could individually prove to be very popular and substantial enough to warrant their own sites.
Should I separate my niche subjects into separate sites?
Should I have one big megasite instead that could pull in sizeable traffic?
After the site has been established for a year or so, I will be selling info products so should I remove advertising when I do so?
Thanks in advance
