File-Sharing: Web sites that host directories of music, movies, games and other software. Users upload content to file-hosting sites and then post descriptions of the material and their download links on directory sites. Uploaders are paid by the file-hosting sites based on the number of times their files are downloaded. The file-hosting sites sell premium download access to the files to the general public. The websites that host the directory services sell advertising and do not host the files themselves.
Cost per click was more common in the early days of affiliate marketing but has diminished in use over time due to click fraud issues very similar to the click fraud issues modern search engines are facing today. Contextual advertising programs are not considered in the statistic pertaining to the diminished use of cost per click, as it is uncertain if contextual advertising can be considered affiliate marketing.
Many voucher code web sites use a click-to-reveal format, which requires the web site user to click to reveal the voucher code. The action of clicking places the cookie on the website visitor's computer. In the United Kingdom, the IAB Affiliate Council under chair Matt Bailey announced regulations[46] that stated that "Affiliates must not use a mechanism whereby users are encouraged to click to interact with content where it is unclear or confusing what the outcome will be."
A crucial factor promoting the increase in mobile speeds over the forecast period is the increasing proportion of fourth-generation (4G) mobile connections. The effect of 4G connections on traffic is significant, because 4G connections, which include mobile WiMAX and Long-Term Evolution (LTE), generate a disproportionate amount of mobile data traffic.

Content providers are also moving to increase the IPv6 enablement of their sites and services. According to Cisco® IPv6 labs, by 2022 the content available over IPv6 will be about 51 percent. There can be, however, variation depending on the popularity of websites across regions and countries. In addition, specific country initiatives and content-provider deployments have positively affected local IPv6 content reachability.
Although the number of connections is growing 2.4-fold, global M2M IP traffic will grow more than sevenfold over this same period, from 3.7 EB per month in 2017 (3 percent of global IP traffic) to more than 25 EB by 2022 (6 percent of global IP traffic; refer to Figure 12). The amount of traffic is growing faster than the number of connections because of the increase of deployment of video applications on M2M connections and the increased use of applications, such as telemedicine and smart car navigation systems, which require greater bandwidth and lower latency.

Video is the underlying reason for accelerated busy hour traffic growth. Unlike other forms of traffic, which are spread evenly throughout the day (such as web browsing and file sharing), video tends to have a “prime time.” Because of video consumption patterns, the Internet now has a much busier busy hour. Because video has a higher peak-to-average ratio than data or file sharing, and because video is gaining traffic share, peak Internet traffic will grow faster than average traffic. The growing gap between peak and average traffic is amplified further by the changing composition of Internet video. Real-time video such as live video, ambient video, and video calling has a peak-to-average ratio that is higher than on-demand video.

Some merchants run their own (in-house) affiliate programs using dedicated software, while others use third-party intermediaries to track traffic or sales that are referred from affiliates. There are two different types of affiliate management methods used by merchants: standalone software or hosted services, typically called affiliate networks. Payouts to affiliates or publishers can be made by the networks on behalf of the merchant, by the network, consolidated across all merchants where the publisher has a relationship with and earned commissions or directly by the merchant itself.

The rapid growth of mobile data traffic has been widely recognized and reported. The trend toward mobility carries over into the realm of fixed networks as well, in that an increasing portion of traffic will originate from portable or mobile devices. Figure 21 shows the growth in Wi-Fi and mobile traffic in relation to traffic from wired devices. By 2022, wired networks will account for 29 percent of IP traffic, and Wi-Fi and mobile networks will account for 71 percent of IP traffic. In 2017, wired networks accounted for 48 percent of IP traffic; Wi-Fi accounted for 43 percent; and mobile or cellular networks accounted for 9 percent of total global IP traffic.
The Internet does not employ any formally centralized facilities for traffic management. Its progenitor networks, especially the ARPANET established early backbone infrastructure which carried traffic between major interchange centers for traffic, resulting in a tiered, hierarchical system of internet service providers (ISPs) within which the tier 1 networks provided traffic exchange through settlement-free peering and routing of traffic to lower-level tiers of ISPs. The dynamic growth of the worldwide network resulted in ever-increasing interconnections at all peering levels of the Internet, so that a robust system developed that could mediate link failures, bottlenecks, and other congestion at many levels.[citation needed]

While these models have diminished in mature e-commerce and online advertising markets they are still prevalent in some more nascent industries. China is one example where Affiliate Marketing does not overtly resemble the same model in the West. With many affiliates being paid a flat "Cost Per Day" with some networks offering Cost Per Click or CPM.
Websites and services based on Web 2.0 concepts—blogging and interactive online communities, for example—have impacted the affiliate marketing world as well. These platforms allow improved communication between merchants and affiliates. Web 2.0 platforms have also opened affiliate marketing channels to personal bloggers, writers, and independent website owners. Contextual ads allow publishers with lower levels of web traffic to place affiliate ads on websites.[citation needed]
●   5G roll-outs provide mobility innovation and new levels of fixed/mobile convergence. By 2022, 22 percent of global Internet traffic will come from mobile (cellular) networks (up from 12 percent in 2017). By 2022, about 3 percent of global mobile devices/connections will be 5G-capable (and nearly 12 percent of global mobile traffic will come from 5G). As expected, mobile carriers from around the world are beginning to introduce trial 5G networks (see 5G Availability Around the World from Lifewire). Many industry experts believe that large-scale 5G deployments will begin to take shape in 2020, when mobile spectrum, standards, profitable business plans and other operational issues are more fully fleshed out.
As in the case of mobile networks, video devices can have a multiplier effect on traffic. An Internet-enabled HD television that draws 2 hours of content per day from the Internet would generate as much Internet traffic as an entire household today. With the growth of video viewing on smartphones and tablets, traffic from these devices is growing as a percentage of total Internet traffic. Share of PCs to total global Internet traffic will decline to 19 percent by 2022, down from 49 percent in 2017. Smartphones will account for 50 percent of total global Internet traffic by 2022, up from 23 percent in 2017 (Figure 5).
Hotels, cafes, and restaurants will have the highest number of hotspots by 2022 globally, and the fastest growth is in healthcare facilities (hospitals), where hotspots will triple over the forecast period. The primary objective of Wi-Fi in hospitals is to improve the delivery of healthcare services and staff productivity, with a secondary benefit being Internet access for patients, their families, and their guests.
Content providers are also moving to increase the IPv6 enablement of their sites and services. According to Cisco® IPv6 labs, by 2022 the content available over IPv6 will be about 51 percent. There can be, however, variation depending on the popularity of websites across regions and countries. In addition, specific country initiatives and content-provider deployments have positively affected local IPv6 content reachability.
DDoS attacks can represent up to 25 percent of a country’s total Internet traffic while they are occurring (Figure 17). In 2017 the top motivation behind DDoS attacks was criminals demonstrating attack capabilities, with gaming and criminal extortion attempts in second and third place, respectively. The events from 2017 and the first quarter of 2018 once again demonstrated that the attackers are increasing their computing resources to perform DDoS attacks. Amplification attackers, who have tools for carrying out a DDoS attack, exploit vulnerabilities in the network and compute resources. Security vendors continue to make sure these attacks are financially unviable for the cybercriminals.
This initial estimation of potential IPv6 traffic is based on the assumptions that IPv6 device capability, IPv6 content enablement, and IPv6 network deployment will keep pace with current trends and may even accelerate during the forecast period. Considering the interdependence of these variables, forecast assumptions could be subject to refinement as our analysis continues.
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]
