But dear most of the directories ask u to put a reciprocal link to ur site.... which I don't want. I'm using a directory submitter for my site as http://directorysubmitter.imwishlist.com/ which is free to submit at 350 directories... Any easy method to submit to directories without any hassles.... Bye.......
Its the niche products/subjects that will always get the highest per click, I remember my highest earners were to do with the medical side of life and various seldom heard of ailments! also sites to do with various 'Law' related information have very high $ per click values at times...
