The products and services you will be promoting to your audience must be relevant and good quality. Make sure you believe in them and know everything about them, because this will be crucial to you delivering the sales pitch to your audience. You need to build trust with your audience so make sure the products and services you choose to promote are trustworthy enough.
Once you've signed up, you'll be able to create unique links that allow the company to track them back to you so you get credit for the referrals you provide. It's important to read the fine print to know the limitations of how and where you're allowed to include the links because it varies from program to program. You can then start dropping these links into places where readers are likely to click on them and buy whatever is being advertised. These places include blog posts, newsletters, and Twitter and Facebook posts. (See also: How to Earn Extra Income With Twitter)
Good point about reviewing online courses before you promote them to protect your reputation. However, I would like to point out that the level of attention the course creator gives you (the endorser) and what they give to a random customer might be very different. There are so called marketing gurus out there who are extremely skilled at making false promises and not delivering on them. Once they have the endorsement of a few reputed marketers and some ‘lucky’ customers, they can easily get away with ripping other people off with hyped up money making guarantees. I have had a personal experience with this as a customer, but lets not mention names! The point is, when we are promoting someone, we need to do an in-depth due diligence. Only going through their course is not enough. It would be great if there was some kind of a course review site -something like tripadvisor. This is something that the industry really needs – something to make people accountable. A lot of people are losing faith in these online courses. I am staying away from promoting people unless I am very certain of their integrity.
