Pros and Cons of Ad Networks

[sammyking]

I have a small blog which is getting decent amount of traffic from quite along time (6 months). My content in my site are super relevant to my niche, yeah it may take some to update my blog (2 times a month most) but I make sure my visitors are all along comfortable to my site. I starting to interest in making some money from it. So, if anybody will give me some specifics about the pros and cons of using an ad network for monetizing any site will be very grateful.
