Before you promote your site, you want to have some substantial content there. Write several product reviews. Have at least two to three in each category you've created. You may also want to create categories for articles, news, and commentary about your topic. The more content your site has, the better. And the great thing is that while you're writing all this, the search engines are getting notified automatically, assuming you turned on the necessary notifications.
High-ticket consulting or coaching: You could sell your own high-ticket consulting or coaching products from your website. You'll still need a website, merchant account, sales funnel, lead magnet and many other items. But you can easily earn a substantial amount of money from each individual customer, making it well worth the arduous setup required.
I have found that one size doesn’t fit all. Rather, specific types promotions of particular products work well with Amazon. I have also had some success by getting people in the Amazon door for other reasons. For example I’ve experimented a couple of times on dPS with running a posts that gave readers a hypothetical $1000 to spend on photography gear and asked them to surf around Amazon and choose what they wanted to buy. The result was 350 comments (a fun community building exercise) and quite a few sales and commissions!
Find a profitable niche. Starting with your interests, write down as many niche ideas as you can. Think about topics people might search online. Ideas include passions (like surfing or body building), fears (like spiders or speaking in front of crowds) and problems (like getting out of debt). Do keyword research to see it others are interested in the topic. Find out if a domain name is available that matches the keyword 100 percent. 
The phrase, "Affiliates are an extended sales force for your business", which is often used to explain affiliate marketing, is not completely accurate. The primary difference between the two is that affiliate marketers provide little if any influence on a possible prospect in the conversion process once that prospect is directed to the advertiser's website. The sales team of the advertiser, however, does have the control and influence up to the point where the prospect either a) signs the contract, or b) completes the purchase.
In my experience, it’s product-related blogs that tend to do best with Amazon. Most blogs probably have at least some possibilities (for example here on ProBlogger I occasionally link to a book that relates or a computer or electronic tool that I think might be useful to bloggers) but the reality is that this blog will never convert as well on Amazon as my photography site.
Pro tip for first-timers: Carefully consider the pay rates that are listed. Penny Hoarder Carson Kohler has used the platform to find freelance writing gigs, and she reports low rates — like $3 for 500 written words. It’s probably not worth it. (And, yes, you’ll have to scroll through a whole lot of these low-paying listings to find the good ones.)
There are many ways in which you can make money with WordPress. Creating a website for the purposes of promoting a business or selling goods through an online store is one such way. Monetizing a blog with display ads is another. While there are other ways in which you can use your WordPress site to make money, perhaps one of the easiest ones to get started with is affiliate marketing.

I have a free WordPress website with 1000-2000 visitors/month. I was trying to place Amazon Affiliate ad links last night and failed/flailed mightily. I would paste the links into my posts in the HTML mode, switch to Visual mode, and could see the image. However, every time I tried to save or update the post, the image reverted to the gangly hyperlink. As some suggested, I tried cleaning the links of any formatting from the copy and paste with text edit. No dice.
