Whats the best choice

I made an Auto*Blog with W*p *Robot

It contains the categories like the Article'8Base website


What keyword should i try to rank for because i get all articles put up.
I don't have a niche. I have ad*sense, info*links and click*bank on it but i didn't make anything and i had it for 2 months.

I don't get any traffic other then 4 spam comments.

What should i do? Should i sell it and make a new one or can i actually get traffic on it.

I also bought Scrape*box yesterday and am trying to get some backlinks.

use a keyword research software such as market samurai to define a niche then dominate that niche

Where do I get the content to put on my site if a pick a niche? I can't write 100's of articles.
