I got domains with PR and backlinks, what now?

hi blackhatworld

I'm interrested in knowing how I can use my domains best.

I have bought around 10 domains, country domains for my own country, and they all have PR3+ and backlinks from authority websites. No spam backlinks.

I want to know how I can utilize this best? Atm I have just put links to all my affiliate websites in a widget on every site, and I have started creating a unique article for every website.

It have really boosted my websites, and nearly all of them are at page 1. The EMD update havent hit our country yet, so before it do I want to create 1 authority website for mobile prices. So how do I utilize this best?

Should I put a blog network, and how do I do this?

Or should I just make 10 separate websites with 3-5 unique articles about mobiles and link them to my money website?

How would you do?

Thanks for your help.
