Content Marketing ROI Calculator for Agency Client Reporting
Why This is an Opportunity
Content agencies live and die by proving value, but the math connecting blog posts to revenue is multi-step and different for every client. A generic ROI calculator won't work because each client has different conversion funnels and deal sizes. The solution is a per-client calculator where the agency inputs the client's funnel metrics once, then updates traffic numbers monthly to generate a rolling ROI view. The app does the multiplication chain and outputs a shareable report. This is a form + calculator + PDF/link report generator. Extremely simple math, but the presentation layer — a professional, branded report — is the real value. CRUD for client profiles, form inputs for monthly metrics, calculated output with a report template.
Key Pain Points
- •Clients ask 'what's the ROI of our content investment?' and the agency scrambles to build a one-off spreadsheet
- •The math connecting traffic → leads → revenue requires 4-5 multiplication steps that are easy to mess up in a spreadsheet
- •Each client has different funnel metrics so there's no reusable template — every calculation starts from scratch
- •Reports showing only traffic and rankings feel weak compared to competitors who present dollar-value attribution
- •Agency account managers who aren't data-savvy avoid the ROI conversation entirely, increasing churn risk
Original Discovery
Content marketing agencies struggle to prove ROI to clients in concrete dollar terms. They can show traffic growth and keyword rankings, but connecting that to revenue requires a chain of assumptions: organic traffic → leads → conversion rate → average deal value → attributed revenue. Most agencies either skip this calculation entirely or build one-off spreadsheets per client. A calculator-style web app where agencies input client-specific metrics (monthly organic sessions, lead conversion rate, sales close rate, average deal value) and generate a clean, branded ROI report showing the dollar value of their content work would help agencies retain clients and justify rate increases.
