Traffic Acquisition Cost (TAC)
A key digital marketing metric that quantifies what a business spends to draw visitors to its online properties through paid channels.
Definition
Traffic Acquisition Cost (TAC) represents the total amount of money a company allocates to attract visitors to its website or app via paid online channels such as search engines, social media ads, display campaigns, and affiliate networks. It helps organizations understand how much they are spending to generate traffic and evaluate the efficiency of their marketing efforts. TAC is often used to assess the return on investment (ROI) of marketing and advertising strategies. Monitoring this metric enables marketers to refine budget allocation and optimize campaigns for better performance. In broader digital business contexts, TAC can also impact profitability and financial health.
