Monthly scenario results

This is a steady-state monthly scenario, not a forecast or observed incremental SEO result. Search volume × CTR is a simplified click assumption, not unique visitors. Existing organic revenue, branded-query overlap, implementation time, taxes, refunds, and other costs are not modeled. Conversion value is treated as revenue per conversion; apply margin consistently if you enter lead value. Expected conversions may be fractional. At zero SEO cost, ROI is undefined. The English interface displays USD; keep conversion value and cost in the same currency and period.

Worked monthly example

With 5,000 searches, 5% CTR, and a 2% conversion rate, the model gives 250 clicks and 5 expected conversions. At $2,500 revenue per conversion, 40% gross margin, and $10,000 SEO cost: revenue is $12,500, gross profit is $5,000, contribution after cost is −$5,000, and scenario ROI is −50%. These are illustrative inputs, not a benchmark.

Formula and assumptions

Clicks = search volume × CTR; conversions = clicks × conversion rate; revenue = conversions × value per conversion; gross profit = revenue × gross margin. Scenario ROI = (gross profit − SEO cost) / SEO cost × 100. Rates are divided by 100 and intermediate values are not rounded.

Use low, base, and high assumptions side by side. Do not count existing organic revenue as new SEO gain; measuring realized impact requires a separate baseline, attribution method, and cost record. Calculations run in this browser and inputs are not sent to the server by this tool.

For observed inputs, compare Search Console clicks and impressions with analytics events and key events; the tools measure different parts of the journey. Read Google's Search Console and Analytics data guide and the current key events and conversions explanation.
