It’s dependent on traffic. Traffic goes up and down and you never know when it is going to do a major dip. Most advertisers pay based on the number of views their ad will get. This turns you into a traffic monster. You start to look for creative ways to get any kind of traffic, no matter if it’s good traffic or not. This can easily lead to your site becoming another junk site that you try to avoid.
I will also tell you that I believe, based on my experiences so far (and the experiences of my bloggy friends) that if you are not willing to invest, you will either not succeed at all – or it will take you a very very long time. The money I have put into this blog has not only motivated me to succeed, but it allowed me to succeed, by learning (quickly) the things I needed to know.)
22. Advertising – This is definitely the most old-school way of earning money with a blog. It’s also starting to become the least common way. You can sell advertising spots directly on your site or you can sign up with a company like Google AdSense or Media.net. Either way, you won’t see a whole lot of money from ads until your views are well into the thousands each day.
Perhaps the most popular network for placing these types of ads is Google AdSense. With this program, you do not need to be in direct contact with advertisers; you simply place the banner on your site, Google chooses ads relevant to your content, and your viewers click on the ads. There are countless similar programs available if you find that AdSense doesn’t work for you, such as Chitika, Infolinks, and Media.net.
