in a bidding directory are you bound to get the homepage appearance(depends) so this helps your site. Homepage gets more hits than others(agree or not). So if you are in a quality bidding directory and in the home page or atleast the first page of your category, beats a listing in a general directory listed in the deepest category as featured.
Here is one fresh wordlink directory I found, pr5 links only $1. I registered my hypnosis site. tvace.info
that depents on the site which you are buying links. if you mean bigweblinks.com, i'm sure having a link that site will help you so much because it's highly promoted directory . most of its subpages have great pr
these bidding directories can turn into link farms when it has a few dozen sites, less and less PR will be passed to you so its not that great after a while
tvace.info is a fake pagerank or buy less digpagerank tell that tvace.info is pagerank 5 in red = fake Regards!
