I hope I can explain this without confusing anyone. We have a sister website (call it abc_dot_com) that provides a registration service for sites with very high domain trust and authority. The trusted websites link directly to abc_dot_com. Currently, all abc_dot_com pages are the property of the various customers. abc_dot_com has 27,000 pages, many PR3/PR4 and up. abc_dot_com has a MOZ domain authority of 50. abc_dot_com does not have any front end landing pages. It is just a vehicle for the registration service. All of the pages are registration forms for our customers' customers. Questions: 1. We can do anything we want with a single footer link on abc_dot_com's 27,000 pages. (ex: Valuable Keyword by XYZ Company) on those pages, but with the way our software is configured, we can't vary the footer links for link diversity. We can do a double or triple link like "Valuable Keyword by XYZ Company" Or "Valuable Keyword and Valuable Keyword by XYZ Company". How would you use these links for maximum ranking benefit for another site (XYZ_dot_com)? Obviously, using valuable keywords in the footer and pointing 27,000 links at XYZ_dot_com is just begging to get hit by G. Our initial thought is to create a page on abc_dot_com and point all of the footers at that page. Then link from that page to XYZ_dot_com. Any other, better suggestions? 2. If we wanted to go black hat, what would you do with this site? Bear in mind that the registration business is profitable, and we don't want to piss off our customers. Whatever we do needs to be invisible and Penguin/Panda proof.
