So I have several blogs with pretty decent pr. http://chelloa.tumblr.com/ PR 2 http://foodalish.tumblr.com/ PR 1 http://simplycars.tumblr.com/ PR 2 http://lego-land.tumblr.com/ PR 3 http://orkou.tumblr.com/ PR 1 I was thinking of starting 1 blog for everything. And I was going to categorize it by tags. This is what the blog would be like: http://sorkoua.tumblr.com/ I have 1,000+ photos on this blog atm^ Do you guys think I should create a new blog for every topic/niche, or just have one giant blog. ------ Or can somene explain to me the concept of niche? I'll use porn as an example. Why create a separate website for anal,blowjob,ebony,redhead, when you can put them all into one general porn website? People always say to find a niche, why can't they all just be in one?
