I have a Wordpress.com web 2.0 that is getting in around 350 visitors a week. Right now I'm setting up analytics to see which keywords its ranking for. This blog is one of my tier 1 links pointing at my money site. I have a PBN of web 2.0 and some expired domains all linking to my money site. Now my question is, should I use the same PBN to push juice to my Wordpress.com blog and rank my keyword? Wouldn't it leave a footprint if I'm linking to both my money site and a tier 1 linking to my money site? OR should I just set up a new PBN for that specific site? I was also thinking about 301 redirecting an expired domain to the Wordpress.com, any thoughts on that? Thanks a lot guys, I wouldn't even be getting any traffic if it wasn't for this forum.
