Not necessarily, but a blog is really the best promotional tool. With that said, you can always use methods such as PPC or advertising to promote a product. This is more like hit-and-run affiliate marketing, however. The best way to make the most out of your affiliate marketing opportunities is to have a blog and use it for hard and soft promotion.
I’d stick with Amazon if I were you. All of my Amazon sites only have Amazon affiliate links. If you use Google Adsense display ads on your site, you’re literally taking people away from your site for the sake of just a few cents with these type of ads. If you direct them just to Amazon, then you have a greater chance of earning more money from that click.
The easiest and most common way to start building an audience for a website is via social media. Depending on your niche and industry, you can choose from Facebook, Twitter, Instagram, Pinterest and several other niche and location-specific networks. Building up an engaged and interested following on social media is a great opportunity to build relationships and once you have their trust, promote your products and services to them.
Many advertisers are unaware of the potential of the affiliate marketing business model for their own businesses, in fact, most small businesses have never heard of it. But imagine marketing your products only to interested people for no upfront fee. Paying only when you get results is a risk-free way of advertising that requires no marketing budget to get started. As you can imagine, this is great for any start-up business with little funding for marketing their new brand.
Mistake #3: Giving your friend’s product a glowing review without actually being familiar with your friend’s product. This happens a lot in the affiliate marketing (and book marketing) world unfortunately. It’s a “scratch my back and I’ll scratch yours” type of situation. By all means, give your friend a glowing review, but if you haven’t actually read their book or taken their course or tried their product, don’t talk about it as though you have. Readers deserve honest recommendations! (Here’s an example of me helping to announce the launch of my friend’s book while being clear I hadn’t read it.)
I think content marketing is absolutely huge for affiliate’s, especially going into 2016, I think it will increasingly become something that will have to be adopted to gain domain trust, authority and good SERP rankings. Google loves quality content and if you want your website to stand the test of time, white-hat SEO is a must and content marketing is king!
