I once wrote the Blogger As A Profession. Apparently it is not easy as I imagined, though actually do not know clearly. PPC ads can be of issue, write a review. The difficulty is that we've published a PPC advertising (pay-per-clicks) but not a lot of blog traffic, so it is also useless, though the blog with page views 1000 per day as possible to get 1 click a day is difficult. I've tried it, the ad appears 1000 times per day but for the ad was clicked only once difficult to achieve.
From the reviews, this is the greatest fortune of ways to get money from blogs. But rarely get a job review. In Indonesia there is one that provides services bring together advertisers with bloggers who review format, namely idblognetwork.com. Sometimes our blog does not match the theme that will also not be advertised to. If we do not credible blogs will also be difficult.
So it is not easy, and unreliable. Find a job in the real world. Enjoy blogging as a means of sharing stories, knowledge and so forth. And do not make money so the main goal, because when money (income), the main objectives and we can not achieve it be to make us disappointed. And will leave the blogging. Even on my blog publishes PPC ads but will not be making income source. Indeed tide, sometimes there is luck sometimes not. And not too much to make the blog so full of advertising, placing it at the appropriate position that does not interfere with visitors in the reading. Thank God already had a steady job, so if anything can be money from blogging may be just enough to subscribe to the Internet
