SEO forecasting: how to predict organic traffic and revenue [free calculator]
A step-by-step method to forecast the organic traffic, leads and revenue your website can get from SEO, adjusted for AI Overviews, with a free calculator you can use right now.
Short answer
An SEO forecast multiplies the monthly search volume of each target keyword by the click-through rate expected at your target position, adjusts for AI Overviews, and then applies your conversion rate and customer value. For example, 1,900 searches a month at position 3 (about 10% CTR) with an AI Overview (−40%) gives roughly 114 visits per month.

Add up to three keywords with their monthly search volume, your current position (use 50 if you do not rank) and your target position.
| Keyword | Volume | Now | Target | AI Overview? |
|---|---|---|---|---|
CTR by position based on public CTR studies; keywords with an AI Overview are reduced by 40%. Estimates, not guarantees.
How to build an SEO forecast in 6 steps
- List your target keywords and group them by page.
- Get search volume from Ahrefs, Semrush or Google Keyword Planner.
- Get current positions from Google Search Console.
- Set realistic target positions by looking at the authority of the pages that rank today.
- Apply a CTR curve (about 28% for #1, 15% for #2, 10% for #3) and reduce keywords with AI Overviews: Ahrefs estimates the top result loses about 58% of clicks when one appears.
- Turn traffic into money with your conversion rate and customer value, and add a timeline: most results arrive between months 4 and 12.
Common forecasting mistakes
- Assuming position #1 for every keyword.
- Ignoring AI Overviews and ads that push organic results down.
- Using one global CTR curve for brand and non-brand searches.
- Forgetting seasonality.
- Never comparing the forecast with real results.

FAQ about SEO forecasting
What is SEO forecasting?
SEO forecasting estimates how much organic traffic, leads and revenue a website can get if it reaches certain positions for its target keywords, using search volume, expected click-through rate by position and conversion rates.
How accurate is an SEO forecast?
It is an estimate, not a promise. Rankings depend on competitors and algorithm updates, and AI Overviews reduce clicks on some searches. Use ranges and update the forecast every quarter with real Search Console data.
What data do I need for an SEO forecast?
Target keywords with search volume (Ahrefs, Semrush or Keyword Planner), current positions (Search Console), a CTR curve, your conversion rate and the average value of a customer.
Is there an SEO forecast template?
Yes: the calculator on this page follows the same logic as a spreadsheet template: volume × CTR at the target position × AI adjustment × conversion rate × customer value.
