1.Google AdSense
https://www.google.com/adsense/
Google AdSense is a free, simple way for website publishers of all sizes to earn money by displaying targeted Google ads on their websites.
How does Adsense Work (for publishers)?
So, how does Adsense work? It starts with the advertisers who choose which keywords they would like to advertise on. Let’s suppose I want to advertise my new line of gardening tools that I just created. I would bid on certain keywords like “gardening, gardening tools, tillers, pulling weeds, etc”
The Adsense spiders would then match my ads up with :
- Those specific keywords that people type into Google and display them to the top and right of the search results
- Websites (like yours) that display adsense ads.
2. YouTube videos

According to recent stats we now watch more videos on YouTube than searches on Google. And with the recently introduced YouTube Partner Program you can now profit from making and uploading videos. You will receive a percentage of the advertising revenue collected per 1,000 views. Depending on how successful you are (virality, subscriber base and topic) you can make a lot of money, and there are plenty of stories every week of more and more YouTubers making it their career.
