Thanks for your reply, Kurt.

There are some projects where I can't or don't want to build a site that ranks organically (fleeting trends or keywords which are difficult to rank for), so I just capture traffic on interlinked social properties and send visitors to a single domain where I track everything and host all of my landing pages.

The thing is, it's not cost effective to have a tracking/landing page farming domain like this for all of my campaigns / keyword groups. One is enough since I can't / don't want to capture organic traffic and getting penalized by social spamming or lack of theming is not an issue here.

Lately I spotted some guys snooping around one of my terminal. I know what they are doing because I do the same. They looking for my backlinks to reverse engineer my profitable campaigns.

I don't do sacrifice linking on social properties, as they already have authority. I also use an interlinking pattern which practically makes it superfluous. And if I would aggregate keyword authority on third party sites before my terminals I would end up with the same situation of having the need for at least one domain per campaign. I sometimes bounce visitors through a shadow domain if I see some hope for quick rankings but that's more of an exception.

The only solution I came up with so far to protect my campaigns was to segment my backlink network on subdomains, using one subdomain per each tracked redirect. It's only an idea so far and may not work at all. What you think?

I also understand that hiding backlinks is not possible if you don't own the sites linking to you, and hiding when they do is a footprint.
