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.
With offline marketing, it's very difficult to tell how people are interacting with your brand before they have an interaction with a salesperson or make a purchase. With digital marketing, you can identify trends and patterns in people's behavior before they've reached the final stage in their buyer's journey, meaning you can make more informed decisions about how to attract them to your website right at the top of the marketing funnel.
With affiliate marketing, you have no control over the product you are promoting. You cannot control the look, description, pricing, or the after-sale service of the product. This does not suit everyone. This can limit what you can do as an affiliate marketer from an advertising point of view. You may not be able to mention certain features due to your terms and conditions. If you do not personally receive the product you may rely on photos. These may be outdated or of low-quality, making it hard to promote the product effectively.
Google, if you a relying on search traffic, can change how they send traffic, rank your page, and how you show up on the SERPS at the drop of a hat. Really, you don’t have control on boosting your traffic when relying on organic search results because it’s not paid. If you are relying on other people’s traffic or other people’s affiliate offers, it can run dry very quickly. It’s not up to you with affiliate marketing. With drop shipping (or selling your own products or private labeling), you have that control over traffic sources.
“Cost of goods changes from time to time, product prices drop, etc. One mistake I made was not re-calculating all commissions to determine they were set correctly. After doing some digging, I realized that commissions on a few of our products were way higher than what they should have been. One way to fix this is to re-adjust commissions each year,” she explained.
