Select the correct answer. What is the most common type of attribution method in the affiliate and partnerships industry?

Last-click attribution is the most common method because it's straightforward to implement and universally understood. It assigns 100% of the conversion credit to the very last touchpoint a customer engaged with before making a purchase. While not always the most accurate reflection of the entire customer journey, its simplicity makes it a default for many affiliate programs. First-click attribution gives all credit to the initial interaction, which can undervalue later efforts. Multi-touch attribution models distribute credit across multiple touchpoints, offering a more nuanced view, but they are more complex to set up and analyze, making them less common as a default. CPA (Cost Per Acquisition) attribution is a payment model, not an attribution method.
