Spam is the biggest threat to organic search engines, whose goal is to provide quality search results for keywords or phrases entered by their users. Google's PageRank algorithm update ("BigDaddy") in February 2006—the final stage of Google's major update ("Jagger") that began in mid-summer 2005—specifically targeted spamdexing with great success. This update thus enabled Google to remove a large amount of mostly computer-generated duplicate content from its index.[33]

Globally, devices and connections are growing faster (10 percent CAGR) than both the population (1.0 percent CAGR) and Internet users (7 percent CAGR). This trend is accelerating the increase in the average number of devices and connections per household and per capita. Each year, various new devices in different form factors with increased capabilities and intelligence are introduced and adopted in the market. A growing number of M2M applications, such as smart meters, video surveillance, healthcare monitoring, transportation, and package or asset tracking, are contributing in a major way to the growth of devices and connections. By 2022, M2M connections will be 51 percent of the total devices and connections.
Affiliates were among the earliest adopters of pay per click advertising when the first pay-per-click search engines emerged during the end of the 1990s. Later in 2000 Google launched its pay per click service, Google AdWords, which is responsible for the widespread use and acceptance of pay per click as an advertising channel. An increasing number of merchants engaged in pay per click advertising, either directly or via a search marketing agency, and realized that this space was already occupied by their affiliates. Although this situation alone created advertising channel conflicts and debates between advertisers and affiliates, the largest issue concerned affiliates bidding on advertisers names, brands, and trademarks.[39] Several advertisers began to adjust their affiliate program terms to prohibit their affiliates from bidding on those type of keywords. Some advertisers, however, did and still do embrace this behavior, going so far as to allow, or even encourage, affiliates to bid on any term, including the advertiser's trademarks.

Overall IP traffic is expected to grow to 396 EB per month by 2022, up from 122 EB per month in 2017, a CAGR of 26 percent (Figure 1). This growth represents a slight increase in expectations over last year’s forecast, which projected a CAGR of 24 percent from 2016 to 2021, driven by an increase in the growing share of mobile traffic as a percentage of the total IP traffic.
●   Quantifiable impact of IoT connections and applications is creating new network demands and requirements. IoT connections will represent more than half (14.6 billion) of all global connected devices and connections (28.5 billion) by 2022. While IoT includes a wide variety of low-bandwidth to high-bandwidth applications (from smart meters to smart cars), the segment will represent more than 6 percent of global IP traffic by 2022 (up from just over 3 percent in 2017). In addition to traffic growth ramifications, IoT is also a catalyst for fixed/mobile convergence network innovations and comprehensive network security improvements.
Globally, fixed and mobile network operators are broadly deploying the IPv6 protocol and supporting significant volumes of IPv6 traffic as a percentage of their overall IP traffic. The range of examples include France’s Free Telecom (40%), KDDI (46%), AT&T (63%), Comcast (64%), Verizon Wireless (86%), Reliance Jio (88%), and T-Mobile (94%) [Source: World IPv6 Launch Organization, September 2018]. Per Google, in Sept 2018, the percentage of users who access Google via IPv6 is nearly 25%; up from 11% in May 2017 [Source: Google Statistics September 2018].

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.

●   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.
In 2006, the most active sectors for affiliate marketing were the adult gambling, retail industries and file-sharing services.[21]:149–150 The three sectors expected to experience the greatest growth are the mobile phone, finance, and travel sectors.[21] Soon after these sectors came the entertainment (particularly gaming) and Internet-related services (particularly broadband) sectors. Also several of the affiliate solution providers expect to see increased interest from business-to-business marketers and advertisers in using affiliate marketing as part of their mix.[21]:149–150
Since the emergence of affiliate marketing, there has been little control over affiliate activity. Unscrupulous affiliates have used spam, false advertising, forced clicks (to get tracking cookies set on users' computers), adware, and other methods to drive traffic to their sponsors. Although many affiliate programs have terms of service that contain rules against spam, this marketing method has historically proven to attract abuse from spammers.
Total Internet traffic has experienced dramatic growth in the past two decades. More than 20 years ago, in 1992, global Internet networks carried approximately 100 GB of traffic per day. Ten years later, in 2002, global Internet traffic amounted to 100 Gigabytes per second (GB/second). In 2017, global Internet traffic reached more than 45,000 GB/second. Table 1 provides a view of the historical benchmarks for total Internet traffic.
The modern ransomware attack was born from two innovations in the early part of this decade: encryption and bitcoin. Mirai Botnet, WannaCry, Petya, NotPetya attacks were launched one after the other in 2017. With the Mirai Botnet attack in 2017, compromises and hacking took mainstage with exposing vulnerabilities in IoT in relation to home monitoring and devices. However, the concern is beyond the home as well. Vulnerabilities in smartphone apps can also be used to introduce malware. Vehicle-to-vehicle (V2V) communication and vehicle-to-everything (V2X) communication are being enabled with smart cities and next-generation mobile and Wi-Fi standards. Key fob scanning, taking control over air bag systems, and anti-collision systems are all possibilities. Security will remain a key part of the IoT deployment and proliferation.

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.

With the exception of short-form video and video calling, most forms of Internet video do not have a large upstream component. As a result, traffic is not becoming more symmetric, a situation that many expected when user-generated content first became popular. The emergence of subscribers as content producers is an extremely important social, economic, and cultural phenomenon, but subscribers still consume far more video than they produce. Upstream traffic has been slightly declining as a percentage for several years.
Education occurs most often in "real life" by becoming involved and learning the details as time progresses. Although there are several books on the topic, some so-called "how-to" or "silver bullet" books instruct readers to manipulate holes in the Google algorithm, which can quickly become out of date,[41] or suggest strategies no longer endorsed or permitted by advertisers.[42]
The basis of categorizing work is to classify the type of Internet traffic; this is done by putting common groups of applications into different categories, e.g., "normal" versus "malicious", or more complex definitions, e.g., the identification of specific applications or specific Transmission Control Protocol (TCP) implementations.[10] Adapted from Logg et al.[11]
Cisco’s approach to forecasting IP traffic has been characterized as conservative. Emerging trends and innovations in network architectures, device/connection deployments, and application adoption/usage have the potential to increase the outlook for traffic volumes, shapes and characteristics significantly. Based on our perspective and analysis, the following topics warrant consideration as future “wildcards” in the forecasting process.
Consider how long it takes to download an HD movie at these speeds: at 10 Mbps, it takes 20 minutes; at 25 Mbps, it takes 9 minutes; but at 100 Mbps, it takes only 2 minutes. High-bandwidth speeds will be essential to support consumer cloud storage, making the download of large multimedia files as fast as a transfer from a hard drive. Table 5 shows the percentage of broadband connections that will be faster than 10 Mbps, 25 Mbps, and 50 Mbps by region.
Anecdotal evidence supports the idea that overall use increases when speed increases, although there is often a delay between the increase in speed and the increased use, which can range from a few months to several years. The reverse can also be true with the burstiness associated with the adoption of tablets and smartphones, where there is a delay in experiencing the speeds that the devices can support. The Cisco VNI Forecast relates application bit rates to the average speeds in each country. Many of the trends in the resulting traffic forecast can be seen in the speed forecast, such as the high growth rates for developing countries and regions relative to more developed areas (Table 6).

Per capita IP and Internet traffic growth has followed a similarly steep growth curve over the past decade. Globally, monthly IP traffic will reach 50 GB per capita by 2022, up from 16 GB per capita in 2017, and Internet traffic will reach 44 GB per capita by 2022, up from 13 GB per capita in 2017. Ten years ago, in 2007, per capita Internet traffic was well under 1 GB per month. In 2000, per capita Internet traffic was 10 Megabytes (MB) per month.

Forms of new media have also diversified how companies, brands, and ad networks serve ads to visitors. For instance, YouTube allows video-makers to embed advertisements through Google's affiliate network.[22][23] New developments have made it more difficult for unscrupulous affiliates to make money. Emerging black sheep are detected and made known to the affiliate marketing community with much greater speed and efficiency.[citation needed]
