First-click attribution refers to the marketing attribution model that credits the first touchpoint a customer has with a brand for any subsequent sale or conversion.
Example: Imagine a software company that specializes in project management tools. They have several marketing channels, such as email campaigns, social media ads, and partnership referrals. A potential client first discovers the company through a blog post shared on LinkedIn, which leads them to visit the company's website. Months later, after exploring different options and receiving direct marketing emails, the client decides to subscribe to a service plan. Under first-click attribution, the initial blog post shared on LinkedIn is credited with sparking the interest that eventually led to the sale, despite the multiple touchpoints that occurred afterwards.
Understanding first-click attribution helps businesses allocate their marketing budget towards the channels most effective in driving initial customer engagement, guiding decision-making and strategy for acquiring new leads.
