SEO ROI &Traffic Value Calculator

The engine of this calculator is the click-through-rate curve. Each Google position earns a roughly predictable slice of the clicks for a search. Position one captures around a quarter of all clicks; by position ten that's down to a couple of percent; on page two it's a rounding error. So a ranking jump isn't linear — moving from #8 to #3 can multiply your traffic several times over for the same keyword.

Multiply those extra clicks by how often visitors convert and what each conversion is worth, and an abstract SEO goal becomes a concrete monthly and annual revenue figure — the kind of number that justifies the work to a client or a boss.

CTR values are industry-average estimates drawn from public organic click-through studies. Real CTR varies with SERP features, brand, intent and device, so treat the output as a directional projection, not a guarantee.
