I'm interested, but also stupid this morning:
1. You'll stop adding orders on that domain once you've filled up your ~80 OBLs?
2. Do I have to use the same URL/Anchor for ALL 47 sites? I have a few I'd like to split it between, is that possible?
3. Are the links in different geographical locations, or just different Class C's?
4. Can I keep the service but change the URLs/Anchors on all? The site I'm struggling with and considering this MAY not be worth $50/month ROI, but others are. I am still yet to find out.
5. How are YOU continuing to backlink your domains (if you don't mind)?
6. Will you use Title tags too? I like these...
