One added benefit is that if someone clicks on a link from your website to Amazon and ends up buying multiple items (not just the item you are promoting), then you would get credit for the entire sale! Imagine you recommend a book on Amazon, your visitor goes to Amazon to buy a book - and while they're there they end up buying a new TV, a Sony PlayStation, and some other things... you get credit for all of the sales. Not only that but you also earn from any sales you make in the following 15 days from that customer.

Write content on your blog that is helpful and informative to people who are reading your page. By focusing on one niche, you will be able to focus your content on just one particular market and draw in an audience that is interested and devoted to that niche. You will soon learn that targeting a specific niche has a whole load of benefits that can help you out.
Understand the difference between total revenue and net income. Most income reports tout total revenue. Net income or profit (what really matters) is often buried in the post. I came across an income report recently with a super impressive number in the title (and Pinterest image). It was total revenue. Not until I read the whole post did I learn this blogger spent well over half their total revenue on Facebook Ads alone. On top of that, they had an extensive list of expenses. By the end of the post I realized I had netted more than they did the previous month.
If you’ve spent a lot of time writing that week and just need a break from working on a post, it may be a productive way to spend an hour or two but I personally think your time could be better spent elsewhere. (This isn’t to say that you can’t find success utilizing this method, I just don’t see many/any people doing it and reporting back that it’s really helped them).
Write content. I like to write an article from beginning to end with no breaks. It may take me an hour to write an article or I may be at it all day. Sometimes, content does span a few days, but for the most part, I like to finish a piece of content in one sitting. I then hand over the content to my editor to fix anything from grammar, punctuation, to the general flow of the article. The only thing she doesn't edit is my monthly income report.
