Been thinking about this myself as I started a few new sites recently, and some of them are ranking unexpectedly well in Google. Each site uses a link cloaking method, either cgi
Some of these cloaked links are listed on Google as supplementals, which looks weird, but doesn't seem to hurt my rankings.
While part of me thinks I should disallow the links via the robots file so they won't "pass on" PR
, I'm beginning to think these cloaked links could actually be helping, as most of these sites avoided the sandbox completely.
Curious deal, as the common opinion at Webmasterworld would suggest to disallow, but then, I don't want to mess with the results I'm seeing. Maybe on my next couple sites, I'll disallow the link directories via robots and compare the results.
I would advise using cloaking in all cases, if only to hide your links from prying eyes. The disallowing (or nofollowing)...not so sure about.
