Find a profitable niche. Starting with your interests, write down as many niche ideas as you can. Think about topics people might search online. Ideas include passions (like surfing or body building), fears (like spiders or speaking in front of crowds) and problems (like getting out of debt).

Several websites offer money (after a minimum level of earning) by clicking on advertisements. Hence, they are called paid-to-click (PTC) sites. One has to get registered before the project begins.

The report sounds awesome. I’ve been thinking about doing all my affiliate marketing via Amazon, because they offer amazing products and because they offer commissions on everything that “my” customers are buying. On the other hand, I’ve been thinking about focusing on a few products that I’m currently using. What I’m trying to say is that affiliate marketing is hard, and that finding the right products is actually harder than promoting them.
Not only can affiliates drive sales for you, but they can also boost brand awareness simply by reaching a larger audience and increasing your traffic and exposure. Even if visitors don’t buy anything, they may sign up for your newsletter — that means you’re growing your email list for free and can potentially get a sale by marketing to those visitors in the future. You can even drive offline conversions via something like an in-store voucher through the affiliate program, or you can drive consumers to offline retailers if you don’t sell direct.
Now most affiliate programs have strict terms and conditions on how the lead is to be generated. There are also certain methods that are outright banned, such as installing adware or spyware that redirect all search queries for a product to an affiliate's page. Some affiliate marketing programs go as far as to lay out how a product or service is to be discussed in the content before an affiliate link can be validated.
