So to provide a new update for this. I recently began adding about a blog a week now. I am trying to post at least 15-20 posts to start with for each blog before linking up and getting anything submitted. I'm also not relying on any serious plugins...just good old keyword research first then posts. The true hard part is keeping them all updated now that the network size is getting bigger.
But traffic is up and hopefully so will sales be soon enough...if I'm lucky! TGIF Guys!
