SEO content as a long-term investment — know the numbers
Unlike paid ads that stop working the moment you stop paying, well-optimized SEO content drives traffic for months or years after it's published. But how do you know if the upfront cost is worth it? This calculator gives you a concrete answer: payback period in months and first-year ROI, based on your production cost and estimated traffic value.
Formula: Monthly Revenue = Visitors × Revenue per Visitor. Payback Period = Cost ÷ Monthly Revenue. 1-Year ROI = (12-Month Revenue − Cost) ÷ Cost × 100. Example: $300 content, 500 monthly visitors, $0.20/visitor → $100/month, 3-month payback, 300% 1-year ROI.
To estimate revenue per visitor: ad-based sites use RPM ÷ 1,000; e-commerce uses conversion rate × average order value; lead gen uses close rate × deal value. SEO content typically ranks in 3–6 months, so treat this calculator as a steady-state projection, not a day-one forecast.
