Hands down I’d say the best thing you can do is research 1 primary keyword, craft an enticing article title that includes your keyword (though it doesn’t have to be an exact match), spend time writing your search engine snippets (SEO titles/meta descriptions), and by far the most important is making your content as VALUABLE as possible through videos, nice graphics, table of contents, bold/colors/styling, etc. Small things like keyword density barely matter.
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.
Consider joining up with an affiliated marketing company. One easy way to enter the field of affiliate marketing is to join a company that specializes in online marketing. Though you'll ultimately work independently, companies like MoreNiche allow aspiring affiliate marketers to join for free to have a platform for advertising products/services.
Amazon’s affiliate program is the most popular of them all. I don’t participate myself (yet) but the majority of affiliate marketers I know use Amazon because… it’s Amazon. You can review products you have used or write tutorials (eg. how to connect computer to TV) and drop an affiliate link to an HDMI cable… just a couple examples. You may want to build relationships with the manufacturers so you can get products before they’re released – giving you time to create a review before the product is launched and capture sales during peak buying times.
Once your hosting is set up, you need to install a content management system (CMS) for your site. We recommend WordPress because it is easy to use and a beginner (like you!) can quite quickly figure out how it works. Most good hosting providers will have a one-click install option for WordPress, which means it will only take you a couple of minutes and you will have WordPress installed on your site.
Since you’re essentially a freelancer, you get ultimate independence in setting your own goals, redirecting your path when you feel so inclined, choosing the products that interest you, and even determining your own hours. This convenience means you can diversify your portfolio if you like or focus solely on simple and straightforward campaigns. You’ll also be free from company restrictions and regulations as well as ill-performing teams.
The terms of an affiliate marketing program are set by the company wanting to advertise. Early on, companies were largely paying cost per click (traffic) or cost per mile (impressions) on banner advertisements. As the technology evolved, the focus turned to commissions on actual sales or qualified leads. The early affiliate marketing programs were vulnerable to fraud because clicks could be generated by software, as could impressions.
If the answer to each of these questions is a resounding yes, rather than jumping to conclusions immediately, take time to research whether or not others are out there making a sustainable affiliate income from products and content in this niche. In a sense, competition is a good thing here—it'll help you validate your idea and prove that it's worth of building a business around.
