Under most affiliate marketing arrangements, advertisers only pay for converted leads. There is basically no way they can lose money or get a negative ROI with this marketing method. Each new sale generated may have a thin margin after the affiliate payment is made, but it’s possible to structure in such a way that eliminates the possibility of a loss.
But this isn't just about posting your ideas on your own blog. You should start authority blogging. Use platforms like Medium to post content. Answer questions on Quora and Reddit. Or get out there onto LinkedIn's publishing platform. These are all authority domains that anyone can post on, which have massive audiences, giving you instant and immediate reach right now.
I always add an HTML table of contents to posts to make sure they are long and structured. This has been a HUGE help for me (and my readers) and there are tons of benefits: better chance of getting “jump to links” in Google (see below), increased average time on page, decreased bounce rates, and it makes it easier for readers to navigate through your content.
While any “regular” job requires you to be at work to make money, affiliate marketing offers you the ability to make money while you sleep. By investing an initial amount of time into a campaign, you will see continuous returns on that time as consumers purchase the product over the following days and weeks. You receive money for your work long after you’ve finished it. Even when you’re not in front of your computer, your marketing skills will be earning you a steady flow of income.
It also shows that you need substantial traffic to make much money through advertising. At a CPM Of £10 with 2 ad units on the site, you would make just £4,000 per month even with a million page views per month for which you serve paid ads to 20% of the audience. Set this to 100% if you are selling all your ad inventory, as for example through Google Adsense.
