1st of all.... Newbs.... Stop using article submitters to submit to PR0 directories. These are worthless... Even 2000 PR0 article submissions are not even worth an article at a PR6 domain such as Ezinearticles. Question for the Pro's though. How many times more effective is PR6 article at Ezinearticles compared with an article at a PR0 domain? Comments appreciated.
sometime PR 0 directories have good traffic. And our article easy to find in SE. So why not PR O? I Love PR 6 directories, but sometime the have difficult rule. But it's okay. I think traffic and PR is not same, and it's influence in our article. That's my opinion. CMIIAW
It depends on the type of links as well, most only allow url links which tend to be useless, some allow anchortext links , which are far more effective
