Indicative estimate based on your inputs. Real results depend on your market, competition and execution quality.

How does this calculator work?

SEO increases the number of qualified visitors who find your site on Google. This calculator applies an organic-traffic growth assumption to your current numbers, then multiplies that extra traffic by your conversion rate and average order value — giving you a clear estimate of the revenue SEO can unlock.

The formula used

Extra revenue = (Current traffic × SEO growth %) × Conversion rate × Average order value

Frequently asked questions

Is this estimate accurate?

It is an educational estimate. A real SEO audit factors in your sector, competition, search intent and keyword potential for a reliable projection.

What traffic growth is realistic?

Depending on your starting point, a well-executed SEO strategy can grow organic traffic 1.5–3× within 6–12 months. Newer sites often see larger percentage gains.

How long until I see results?

First gains typically appear within 3–6 months, accelerating beyond the first year.

What order value should I enter?

Use your average basket for e-commerce, or the average value of a customer / lead for services (e.g. the margin a new client generates).
