I have heard that direcotories do not generate traffic and ........ But good thing i am experiencing is that it really generates traffic if you have website in right category Month Visitors Feb 27
Do you mean visitors to my directory or visitors from my directory? So far in February, my directory is getting about 150 uniques/day. Judging from popular search terms, half of that traffic is adult related meaning that the few adult sites in there are probably doing well. On the other hand, my personal sites listed in the directory have gotten between 1 and 3 visits from the directory so far in Feb.
I find that direct referals from directories are usually pretty meager. If you are in enough directories you will always get some, but not nearly as much traffic as a site with good serps.
