Media reporter Mathew Ingram tweeted, "Not great for media who rely on affiliate revenue[,]" potentially a nod to popular gadget reviews The Wirecutter, which was acquired by The New York Times. Technology journalist Michael Morisy quipped, "Amazon reworks affiliate program, cutting commissions 50% for electronics. Guess they think Jet threat has passed?" in a reference to up-and-coming Amazon rival Jet.com, which sold to Walmart in a deal largely regarded as a failure for the startup.

From time to time, we may run general special programs or promotions that may provide all or some Associates the opportunity to earn additional or alternative fees (“Special Program Fees”). For the avoidance of doubt (and notwithstanding any time period described in this section), Amazon reserves the right to discontinue or modify all or part of any special program or promotion at any time. Unless stated otherwise, all such special programs or promotions (even those which do not involve purchases of Products) are subject to disqualifying exclusions substantially similar to those identified in Section 2 of this Fee Statement, and any restriction under the Program Documents applicable to a Product purchase will also apply on a substantially similar basis as restrictions for special programs or promotions.

In February 2000, Amazon announced that it had been granted a patent[18] on components of an affiliate program. The patent application was submitted in June 1997, which predates most affiliate programs, but not PC Flowers & Gifts.com (October 1994), AutoWeb.com (October 1995), Kbkids.com/BrainPlay.com (January 1996), EPage (April 1996), and several others.[13]
Cost per action/sale methods require that referred visitors do more than visit the advertiser's website before the affiliate receives a commission. The advertiser must convert that visitor first. It is in the best interest of the affiliate to send the most closely targeted traffic to the advertiser as possible to increase the chance of a conversion. The risk and loss are shared between the affiliate and the advertiser.
Data-driven advertising: Users generate a lot of data in every step they take on the path of customer journey and Brands can now use that data to activate their known audience with data-driven programmatic media buying. Without exposing customers' privacy, users' Data can be collected from digital channels (e.g.: when customer visits a website, reads an e-mail, or launches and interact with brand's mobile app), brands can also collect data from real world customer interactions, such as brick and mortar stores visits and from CRM and Sales engines datasets. Also known as People-based marketing or addressable media, Data-driven advertising is empowering brands to find their loyal customers in their audience and deliver in real time a much more personal communication, highly relevant to each customers' moment and actions.[37]

An influencer is an individual who holds the power to impact the purchasing decisions of a large segment of the population. This person is in a great position to benefit from affiliate marketing. They already boast an impressive following, so it’s easy for them to direct consumers to the seller’s products through social media posts, blogs, and other interactions with their followers. The influencers then receive a share of the profits they helped to create.
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. 
Product prices and availability may vary from time to time. Because prices for and availability of Products that you have listed on your Site may change, your Site may only show prices and availability if: (a) we serve the link in which that price and availability data are displayed, or (b) you obtain Product pricing and availability data via PA API and you comply with the requirements regarding use of PA API in the License.

Further, you will not purchase any Product(s) through Special Links or take a Bounty Event action for resale or commercial use (of any kind) or offer any Products on your Site for resale or commercial use of any kind.

No matter how good your marketing skills are, you’ll make less money on a bad product than you will on a valuable one. Take the time to study the demand for a product before promoting it. Make sure to research the seller with care before teaming up. Your time is worth a lot, and you want to be sure you’re spending it on a product that is profitable and a seller you can believe in.

Amazon didn't immediately respond to a request for comment. The email they sent to affiliates said, "We have received feedback from associates that the advertising fee structure could be made clearer, especially with respect to understanding which products are in fixed-fee categories and which products are in tiered-fee categories. These changes simplify the fee structure, clearly defining the advertising fees you can earn by referring traffic to Amazon."
