I have spent the last 2-3 days digging and finding aged domains(not telling don't ask.) They are all from 2006 and older, most of them never been dropped more than twice and each one has Domain authority and/or Page authority over 20 and some in the high 40's(still have data to go through.) The list is at 113 domains at the moment, and I was wondering how powerful a link from each of these domains would be. I checked on Opensiteexplorer and it seems some of them have links from Pr4, Pr5 domains. How much search traffic can I safely go for IF I registered all of these domains? I plan on setting up amazon sites, Clickbank sites, and CPA sites that will use the link juice to rank for these keywords. Would it be a good idea to send all of these links blog comments from the SAME AA list or would that leave a footprint?
