Growth Timeline

Net value, month by month

SEO compounds over time. The bars below show estimated net value (revenue minus monthly cost) as rankings progress from zero to your target position.

Typical ranking progression assumed: ~10% visibility at month 3, ~40% at month 6, ~75% at month 9, full ranking at month 12.

Figures are projections based on average CTR data and your inputs. Actual SEO results depend on competition, content quality, technical health, link authority, and many other factors. Codesky accepts no liability for decisions made based on these projections.

How the SEO ROI Calculator Works

Plug in your keywords

Drop in your target keywords, monthly search volumes, expected click-through rate, on-site conversion rate, average customer value, and your monthly SEO spend. Every input has a hint with realistic UK benchmarks so you are not guessing.

See your projected returns

We translate your numbers into projected monthly organic traffic, leads, new customers, revenue and a clear ROI percentage - so you can see the size of the prize before you commit to a 6- or 12-month SEO programme.

Stress-test the assumptions

Compare pessimistic, realistic, and optimistic ranking scenarios side by side. If the case for SEO still stacks up when you halve your expected CTR or shift to lower-volume keywords, you know the investment is genuinely worth making.
