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.
Essentially, the ads you place on your blog are placed there by advertisers to earn profit and revenue from the traffic coming to your website. One of the best things about AdSense is that it is completely free. This is a great way to earn extra money as you start to gain more growth and traffic to your website. You can even include AdSense ads (as linked text) in your blog’s internal search engine.
Once you setup your account on AdSense you will be given a code to add to your blog. This code will automatically display advertisements on your blog from companies who are part of Google’s advertising network. You may see ads from small companies related to your topic, or you may see ads from large companies that are completely unrelated to your topic.
