The way advertising works with YouTube is probably one of the most complicated things that comes with trying to make money off of YouTube. The real estimate comes out to about $7.50 per 1,000 impressions. The difficult part is actually defining the word ‘impressions.’ The only time you make money on YouTube is when someone interacts with your ad or when it leaves an ‘impression’ on them.
If you're serious about making money online, start a blog. Blogging is one of the easiest and most sustainable income sources. As long as the blog is setup the right way, in the right niche, with the right content targeted at the right audience, and the offer is complementary to the content, you could make a tremendous amount of passive income from a blog.
