The main point here is that you make an attempt to find multiple purposes for the companies that you affiliate yourself with. For example, if you join an affiliate program that you can earn money from both through referrals as well as product sales. So right there you have a sense of ‘multiple streams of income’ even within the same business.
Then what really puts the ‘cherry on the dessert’ is if that company also has resources that you can use to promote it as well as your other opportunities. A company really should provide some free services to help in this regard, but the reference here would be the company’s product being able to be purchased and/or used independently for other purposes.
For example if they sold advertising services or autoresponders. While you should have access to some resources that are free or inexpensive that come with the membership, and are for the purpose of promoting that program, it would be great to have the opportunity to also purchase services for your other businesses directly – a one-stop-shop.
It is not just a matter of efficiency or convenience but actually will help you to articulate what it is about the product that you like so much you would use it yourself. Of course this also comes with real statistics that you can quote after a while.
When writing to promote the program in your blog or otherwise you would have the exact functions and procedures to review. You would eventually also have statistics such as how many sales it has brought in, how many responses otherwise, etc. You can also compare it to other similar products or services.
Being able to give a first-hand review on something you really know about seems to carry more weight than quoting others or even just recording the specs advertised on their sales page. With that said these are useful as well – it’s just a matter of degree. When you really know something first-hand you can be a bit more adamant and compelling to encourage others to follow you. It will come in time either way.
