If you want to be famous or reach a wide audience, you will have to choose something slightly broader and work hard to make the best content for that topic. A subtopic relating to fitness, finance, or relationship advice is likely to reach the most people. Consider specific but broadly applicable topics such as managing money in college, or a marriage counseling blog.
If you are new, obviously don’t try to fit all of these income streams in at one time. You should build on it and work on one at a time. Slowly build your income. Think of it in terms of a job. When you start out at a job you don’t usually start making the big bucks right away. After time and experience come into play, then you start making more and more money with raises and promotions. Now you can make a ton more money online than a typical job but it is the same concept!
Adsense is a contextual advertising network that places partner (business) ads on your website. It’s easy to set up—all you have to do is copy and paste some code given to you from Google in the places you'd like the ads to appear on your website. Google will then show ads from advertisers that are a match to the content on your website so that ideally your website visitors see relevant ads.
Making money through blogging requires a carefully thought out topic. If you have an existing blog with a small audience, be honest when considering whether the topic has broad appeal that isn't already covered by other established bloggers. If it does, great! Otherwise, there's nothing wrong with starting a second blog that will be more successful in attracting an audience, marketing itself, and making money through a variety of methods described below.
Write content. I like to write an article from beginning to end with no breaks. It may take me an hour to write an article or I may be at it all day. Sometimes, content does span a few days, but for the most part, I like to finish a piece of content in one sitting. I then hand over the content to my editor to fix anything from grammar, punctuation, to the general flow of the article. The only thing she doesn't edit is my monthly income report.
