Google AdSense
With Google AdSense, you can auto-populate your website with ads from Google. The ads are filled by advertisers who are using the Google AdWords platform to place ads around the web. You earn revenue as those ads are served to your audience and when they click.
Applying for the program is simple and adding the ad slots to your website is pretty straightforward. Sounds amazing, right?
Well, yes and no. You will need a lot of traffic for AdSense to generate meaningful income on your website. However, it does allow you to focus on generating revenue while Google takes care of the ad sales.
When your website is early, just don't count on it to be a primary source of income. It's a good idea to use Google AdSense as just one of many revenue streams within your online business.
