Guide me on home page linking & deep linking

[cohenmiller91]

Hi buddies! I have been in the online business for just a year. I have understood a lot of factors that I need to consider. However, I am still not clear with home page linking and deep linking. Can anyone tell me about this practice? What do I need to do in order to be successful in obtaining the expected linking? Is this technique essential to attain? Can my site do without it? I would also like to know about the process and the benefits involved. I am looking forward to gain your preferred service. Thank you very much. Regards!
