Understanding link building ROI helps justify investment and optimise resource allocation. Use this framework to estimate the value of your link building efforts.
ROI Calculation Framework
Basic ROI Formula
ROI = (Value Generated - Total Cost) / Total Cost × 100

- Total Cost: £20,000
- ROI = (£50,000 - £20,000) / £20,000 × 100 = 150%
