I just started getting into making various doorway pages and will soon be cloaking some as well after I've run a few tests. I have lots of link building software as well. I'm wondering if anyone can share their knowledge or experience with building links to your doorways...even the cloaked ones. I am seeing so many examples of this still working and am even being outranked on some of my white hat sites by some link spammers! It's very encouraging...If nobody wants to share their experience I understand. I'll just keep testing until something sticks and maybe will come back in here and share what I learn.
