Directory submission gives improves
PR side by side improve search Engine Ranking, S E Optimizers submit in free directories and often says submit your site in root category. Although they submit in root category but maximum times there submission is rejected. Professional submit in deep category but pages take long time to be crawled by search Engine so there site take more time to get a backlink.
But what my thinking is
"if you getting link free, just put your link, Wheather the particular page is crawled or not."
