I am wondering how many link shares I should be doing and what to look for ie. high pr vs amount of link shares. Can anyone tell me what google likes and doesn't like.

Couple of other questions when considering who to link trade with.

How important is inbound vs outbound links. What is the best site to trade with
one with a high in or high out or both?

Yeah mine is a little bizarre because it is a tweeter site. www.tweetsfrompornstars.com
I have pretty much requested people with pornstar themes.

Is it worth anything to trade with another pr0 site or should I be trying to get trades with pr1 sites?

so right now my site is pr0 so what would be the appropriate pr rank sites should I be requesting to trade with?

It allows me to pick more than one site can I do that?

I have a pretty original site which is not your normal adult website for anyone interested in a link trade http://www.tweetsfrompornstars.com

I got my first link trade request. Right now I have one trade request but I am not sure what the add to request buttons are for. Right now this particular request is listing
75 requests. Are these the sites that I can choose to direct traffic to my website?
