If you want to know the best online passive income streams then you have come to the right place. I have over 5 years experience of making money online. There is no doubt about it - passive income is some of the best. So which methods should you invest your time and energies in, in order to make the most money while you sleep?

Adsense Passive Income

Right at the top of the list has to be Adsense. Adsense is a contextual advertising service operated by Google.

Contextual means that the ads served up are usually (they try to be!) relevant to the content that appears around them. Google is all about relevancy and delivering the best user experience possible. It also means that you will make more money.

For example, can you imagine if you wrote an article about the subject of car repair. If you use Adsense then ads relating to car repair will be served up. Naturally, anyone who finds your article via Google in the first place and reads it will be interested in the subject and more likely to click your ads and make you money.

Adsense is available to anyone who wishes to use it. One of the most common ways to implement it is to go to Blogger.com and create a blog and install it on the blog. The site is even owned by Google so they make it really easy.

Email Marketing Passive Income

Another great method of passive income is to create a marketing funnel such as an email list. Have you ever been to a site where you are asked to give your email address in return for an interesting newsletter? Or if you go back to the days before email you may have purchased a product and been asked to register it via a postcard, in order to receive something else of interest.

What happens is that a small percentage of registered users will end up buying something from the marketing information that follows. Of course, you cannot "spam" people once they have signed up. You should provide them with useful information and offers.

The reason that email marketing provides such great passive income is because it is often said that each subscriber to your email list is worth 50 cents per month. So those marketers who have a list of 10,000 people are making around $5,000 per month!

Other Online Passive Income Streams

So what else is out there? Well, the best income streams that are passive are those that deliver search engine traffic for many years to come. Your own blog or site is a great way but there are also revenue sharing sites like eHow and this site, Info Barrel.

Another way to get passive income is to create some kind of automated service where you don't have to do much at all, even if your volumes increase. A really good example is owning your own digital product and then getting affilliates to promote it for you. I do this myself and when I check my email in the morning I can see all the sales made in the USA overnight by my affiliates. I didn't do any of the work and the money was made in my sleep! The Clickbank platform is very popular for this sort of thing and allows you to easily sell your own digital products (ebooks, audios etc.).
