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.
Selling physical products online can be hard to setup as you will need to deal with storage, shipping and even deal with things such as local taxes and distance selling laws. Of course a lot of this headache can be resolved by finding a company who will offer a white-label or drop shipping service leaving you to worry about getting traffic and updating the website.
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.
