Thanks for the info about directory critic. I have been looking for legal directories to list my paralegal service in and had not heard of this resource. I looked at their list of niche directories and found a legal directory right away. As to how much time I spend, I had been setting aside a couple hours on Friday afternoons for the tedious prospect of doing key word searches to find sites to link with, but lately have been too busy having actual clients, lol. I need to start devoting the time again. I do notice an up tick in my web traffic when I put forth the effort to submit to directories and ask others to link back to me.
