i have used directory submission services several times. they were total waste of money. i tried to do it manually myself and its a lot of work. most free ones want reciprocal links. the services i have used? they just give you a bunch of directory sites, some of them are not even alive! most of them will not work because i dont have a reciprocal link. for the rest, i will not know because it takes time to get listed even if they will. it seems that most people just pay for the services and cover their eyes..? so how do you do it? pay hundreds of dollar for each paid directory, and do it yourself? btw, i think directory submission still works because i do see well known sites listed in directories.
