There are many different publisher types to work with and these relationships are facilitated by an advertiser joining the network and using the promotional tools available- these are owned by the publishers. In every case the publisher takes the risk of sending you traffic at no cost to you as you only have to reward them if their traffic completes a purchase- therefore, advertisers only pay out on results.

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.
Smart affiliate program managers understand the value of free.  Instead of telling you to promote their salespage, many offer a valuable freebie that provides real value to prospect.  All you have to do is mention this freebie and provide a place to get it.  After that, the site owner will follow-up with a prospect and sell them on the benefit of purchasing a product.

Find and work with affiliates. Affiliates will help grow your business and help you tap into web traffic. There are many ways to meet and engage with affiliates, but the best way to access desirable affiliates is by building a reputation for yourself. You can do this by developing a popular blog or otherwise earning a large online following, or by becoming a published author of a book or article.[15] There are other ways of meeting affiliates, of course, and each method will vary in its success and required effort. Generally speaking, the basic course of action for acquiring affiliates typically involves one of the following methods:
Most entrepreneurs fall into two key categories: dropshipping vs affiliate marketing. Dropshipping is when the manufacturer carries the inventory and ships it to the customer on your behalf. In dropshipping, you set your own product prices and are responsible for marketing. Similarly, in affiliate marketing, the merchant also carries inventory and ships the product. However, while you’re still responsible for marketing, you don’t get to set the product price and only receive a commission. In this article, we’ll explain the pros and cons of dropshipping and affiliate marketing to decide which is more profitable.

In the past, large affiliates were the mainstay, as catch-all coupon and media sites gave traffic to hundreds or thousands of advertisers. This is not so much the case anymore. With consumers using long-tail keywords and searching for very specific products and services, influencers can leverage their hyper-focused niche for affiliate marketing success. Influencers may not send advertisers huge amounts of traffic, but the audience they do send is credible, targeted, and has higher conversion rates. 

Pay Per Sale or PPS – where companies pay a percentage of all sales that are qualified. These could be a percentage which was agreed by the company and it’s affiliate. Among the most common PPS program is the Amazon Associates where a publisher can earn up to 15% depending on the products that were sold. Here’s a list of places where you can find products to promote.
The primary advantage of affiliate marketing over dropshipping is that you don’t really have anything to do with the product fulfillment process. You don’t have to connect with suppliers, you don’t need to handle transactions, you don’t need to collect money, issue refunds, or otherwise act like a store. All of that is handled by the actual store. All you do is, essentially, hand people your card, point them at the door, and say “tell ‘em I sent you.”
A content marketer, for example, can create a series of blog posts that serve to generate leads from a new ebook the business recently created. The company's social media marketer might then help promote these blog posts through paid and organic posts on the business's social media accounts. Perhaps the email marketer creates an email campaign to send those who download the ebook more information on the company. We'll talk more about these specific digital marketers in a minute.
Affiliate marketing overlaps with other Internet marketing methods to some degree, because affiliates often use regular advertising methods. Those methods include organic search engine optimization (SEO), paid search engine marketing (PPC – Pay Per Click), e-mail marketing, content marketing, and (in some sense) display advertising. On the other hand, affiliates sometimes use less orthodox techniques, such as publishing reviews of products or services offered by a partner.[citation needed]
Content marketing specialists are the digital content creators. They frequently keep track of the company's blogging calendar, and come up with a content strategy that includes video as well. These professionals often work with people in other departments to ensure the products and campaigns the business launches are supported with promotional content on each digital channel.

The General Data Protection Regulation (GDPR), which took effect on May 25, 2018, is a set of regulations governing the use of personal data across the EU. This is forcing some affiliates to obtain user data through opt-in consent (updated privacy policies and cookie notices), even if they are not located in the European Union. This new regulation should also remind you to follow FTC guidelines and clearly disclose that you receive affiliate commissions from your recommendations.
