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.
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.
The topic you choose must have enough depth that you can create a lot of content for it. This is important for building an authoritative site, for search engine optimization, and most importantly, for the end user. If you don't have enough content about a topic, you're not going to be taken very seriously as an authority on the topic and it's unlikely you can convince someone to make a purchase from you.
StackPath – CDN with 31 additional data centers (Cloudflare has 150+ data centers, but more data centers = faster content delivery). I get around $1,000/month by referring people to StackPath in my cache plugin tutorials. StackPath recently bought MaxCDN and their affiliate acceptance rate is much lower (depends on your potential volume) but most cache plugins converted to StackPath as their recommended CDN
Don’t set a goal to write 3 blog posts a day… set a goal to write 1 blog post a week and make that post super helpful, long, and filled with information that is so valuable you will say “yeah, people will link to that.” 90% of my traffic/affiliate income comes from just 20 tutorials, many of which are 5+ years old. But I am constantly updating them to make the content better.
Look for a gravity score of 30 or more, because these products have a proven track record of selling well for a number of different affiliates. Products, especially new products, with gravity scores under 30 may work but are more risky. Gravity scores of greater than 100 mean the product’s popular. You could have competition, but don’t worry about that. The important thing is that there’s lots of demand.
In simple terms, affiliate marketing means selling another person’s or company’s products and services. It’s like a referral service. You set up a website or blog and join affiliate programs that are relevant to your audience. You can connect to these programs through affiliate networks that provide you with a link that you include on your site. When someone clicks the link and purchases the product or service you’re marketing, you receive a percentage of the sale proceeds as a commission.
Do Paul! Affiliate marketing is awesome – and you’re right, it can be overwhelming b/c it can be hard to know who to trust, but it’s a wonderful way to make money online — esp when you’re promoting products/services you are proud of. Let me know if you have any questions. There’s a lot I don’t know … and a lot I do. For what I don’t know, I can find the answer for you.
Good point about reviewing online courses before you promote them to protect your reputation. However, I would like to point out that the level of attention the course creator gives you (the endorser) and what they give to a random customer might be very different. There are so called marketing gurus out there who are extremely skilled at making false promises and not delivering on them. Once they have the endorsement of a few reputed marketers and some ‘lucky’ customers, they can easily get away with ripping other people off with hyped up money making guarantees. I have had a personal experience with this as a customer, but lets not mention names! The point is, when we are promoting someone, we need to do an in-depth due diligence. Only going through their course is not enough. It would be great if there was some kind of a course review site -something like tripadvisor. This is something that the industry really needs – something to make people accountable. A lot of people are losing faith in these online courses. I am staying away from promoting people unless I am very certain of their integrity.
Writing good advertising sales copy (copywriting) is the other important skill for internet marketers. The good news is that when it comes to affiliate marketing, many vendors will provide you with copy to use for your blog posts, websites ads, etc. They'll give you the emails to send, the banner ads to display, and even posts you can use on social media (such as Facebook, Twitter, LinkedIn, etc.).
I expanded my SEO blog and started writing about hosting, cache plugins, and other relevant topics… while recommending SiteGround in each tutorial. I added social proof like this poll where they were rated the #1 host. Each tutorial was super detailed and tons of people found them helpful – many generated 100 visitors/day since the great content got them ranked high.
