Where the calculator can flatter the result
“A 30% uplift and a 6.3x return read cleanly, but the model multiplies a single conversion rate and order value across every incremental visitor, which assumes new AI-search traffic converts as well as your existing best traffic. It rarely does at first. Treat the net ROI as a ceiling for budgeting, run the conservative 15% scenario alongside it, and weight the early months lower than the headline before you commit a retainer.”

How to use this calculator

Enter your current monthly organic visitors, baseline conversion rate, average order value, target uplift, and monthly agency cost. The calculator estimates incremental visitors, conversions, annual revenue, total agency spend over 12 months, net ROI, return multiple, and months to break even.

What good looks like for UK AI SEO

  • Conservative scenario (15% uplift): appropriate for established sites with strong existing SEO. Expect break-even in months 4-6.
  • Realistic scenario (30% uplift): typical for mid-market UK SMEs with foundational SEO and headroom for AI citation growth. Break-even in months 2-3.
  • Aggressive scenario (60%+ uplift): achievable for sites starting from a low base or in low-competition verticals. Break-even within month 1.

What this calculator does not capture

Brand search uplift (AI citations build awareness even without click-throughs), reduced reliance on paid acquisition, lower customer acquisition cost over time, and improved win rates from being the cited authority in your category. Conservative ROI estimates underweight these compounding effects.
