SEO ROI & AI visibility calculator 2026

Estimate the traffic, pipeline and ROI of SEO, and your share of voice in AI answers.

Classic SEO mode works from search volume and target rankings. AI visibility mode works from your mention rate in ChatGPT, Perplexity and Gemini answers. Both give traffic, revenue, ROI and break-even.

Calculate my SEO ROI

How to use the SEO ROI calculator

In Classic SEO mode, enter the monthly search volume of the keyword set you target, your current average position and the position you aim for. In AI visibility mode, enter how often buyers ask AI assistants about your category, how often you are mentioned today and the rate you aim for. Then add your conversion rates, deal value and monthly SEO investment.

The formulas

Incremental traffic = search volume × (CTR at target position − CTR at current position)
AI traffic = AI prompts × (target − current mention rate) × click-through from the answer
Revenue = traffic × visitor→lead × lead→customer × deal value
ROI 12 months = (revenue − investment) / investment, with results ramping up linearly over 6 months
Break-even = first month where cumulative revenue covers cumulative investment

The CTR curve used

Position 1 captures about 28% of clicks, position 3 about 11%, position 10 about 2.4%, and page two about 1%. Moving from position 18 to position 4 on a 12,000-search keyword set is worth roughly 900 visits a month.

Why measure AI visibility in the same place

Buyers now shortlist vendors in AI answers before they search. Being cited less than your main competitor means losing the deal before the first visit. This is the only calculator that puts SEO ROI and AI share of voice side by side, because one SEO/AEO/GEO programme moves both.

Limits

AI prompt volumes are estimates: no platform publishes them yet. Use a conservative value and compare scenarios rather than reading one number.
