What It Is: Transcription essentially involves you listening to audio files and typing out what you hear. Easy enough, right? Companies usually hire transcriptionists without much experience, so some job postings might only require you to have a computer and keyboard to get started. Transcription jobs can vary from transcribing a college lecture to a doctor's medical dictation, while most companies allow you to make your own schedule.
Affiliate marketing is commonly confused with referral marketing, as both forms of marketing use third parties to drive sales to the retailer. The two forms of marketing are differentiated, however, in how they drive sales, where affiliate marketing relies purely on financial motivations, while referral marketing relies more on trust and personal relationships.[citation needed]

Hi, Jamie! Very good list. I needed something like this for 2018 so that I know what to target in the future blogs I create. As for now, I’m comfortable using SiteGround affiliate network and it’s pretty good actually. Their hosting service is pretty much the best considered its price. I’ve tried others but SiteGround stands out. I’ll also try new affiliate networks, something from the list you have just provided. I think Amazon is too saturated at the moment, and I need a better network. 2018 will be interesting indeed.
It’s important to know where your traffic is coming from and the demographics of your audience. This will allow you to customize your messaging so that you can provide the best affiliate product recommendations. You shouldn’t just focus on the vertical you’re in, but on the traffic sources and audience that’s visiting your site. Traffic sources may include organic, paid, social media, referral, display, email, or direct traffic. You can view traffic source data in Google Analytics to view things such as time on page, bounce rate, geo location, age, gender, time of day, devices (mobile vs. desktop), and more so that you can focus your effort on the highest converting traffic. This analytics data is crucial to making informed decisions, increasing your conversion rates, and making more affiliate sales.
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]
