I usually submit one article to any one top directory. Of late I discovered this not only helps PR buy also brings decent no of visitors daily (5 to 10 per article per day).
Now I am thinking to resubmit each article to say at least ten directories. From these I am not expecting a PR benefit but they can definitely bring more visitors I feel?
But my doubt is whether SEs will think this as a black hat method? Please advise me.
