What would better rankings be worth to your business?

It's directional, not precise. The actual revenue impact of SEO depends on dozens of factors this calculator doesn't know about — your competition, your current rankings, your site's technical health, your content quality, and how aggressively you pursue the program. Use the output to understand the order of magnitude of the opportunity, not as a budget forecast. A 75% traffic increase in 12 months is achievable for most small businesses starting from a low baseline — it's not a stretch goal.

Use your actual conversion rate from organic traffic if you have it in GA4 — organic visitors who completed a contact form, called, or booked. If you don't track this yet, 1–3% is a reasonable assumption for a local service business. B2B businesses typically run 1–2%; local consumer services 2–5%; ecommerce varies widely. Don't inflate this number — the calculator is more useful with a conservative input.

Because that's how SEO actually works. Technical fixes and content optimizations start in month 1, but Google needs time to recrawl, re-evaluate, and re-rank the updated content. Most businesses see the first meaningful ranking movements in months 3–5, with significant traffic increases in months 6–9. Month 12 is typically when compounding really shows up — pages that ranked at position 8 in month 3 reach position 3 in month 9, which can triple click volume from the same query.

For a small business starting from under 500 monthly organic visitors with a site that hasn't had dedicated SEO work, 75–150% growth in 12 months is achievable with consistent execution. The lower end (30–50%) is more typical if you're in a competitive market or starting from a larger baseline. Very low-traffic sites (under 100 visitors/month) sometimes see higher percentage growth simply because the baseline is low — but the absolute revenue impact is also smaller.
