there are many dirs on the web. i recommend you to submit your link to the niche dirs. it will give you more relevant traffic => high CPC rates.
Have many people had any luck getting onto Lii it seems impossible or it just me? =) Probably just me
If a good directory is a directory with high traffic and good PR, then no directory is a good directory at the beginning. So what leads a directory to this?
That means there are no good directories. I've got sites listed in all the "leading" directories both free and paid and never had hits in the double figures for the month ever. Directories are a dying industry im afraid, glad i got out a while back.
