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.
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.
