ROI

Return on Investment measures the profitability and efficiency of an investment relative to its cost, expressed as a percentage or ratio. The basic formula divides net profit by the cost of investment and multiplies by 100. In digital contexts, ROI evaluates the effectiveness of marketing campaigns, technology investments, and web development projects.

Calculating ROI for web projects requires defining what counts as return. For an e-commerce site, revenue attribution is relatively straightforward. For a corporate website redesign, returns might include increased lead volume, reduced bounce rates, or improved conversion rates that translate into downstream revenue. Attribution modeling becomes important when multiple channels contribute to a single conversion. Understanding and optimizing ROI helps businesses allocate budgets strategically and justify expenditures on digital initiatives, making it one of the most important metrics in any project proposal or post-launch review.
