Most businesses achieve positive ROI within 6–12 months. Months 1–3: technical fixes. Months 3–6: initial rankings. Months 6–12: organic leads offset the investment.
Professional services 3–5% · Healthcare 2–4% · Home services 3–6% · eCommerce 1–3% · Financial services 2–4%.
After 18–24 months, organic CPL is typically 30–60% lower than paid search. No ongoing cost per click once rankings are established.
Well-maintained SEO programs deliver 500–2,000% ROI by month 24 depending on industry and average customer value.
SEO ROI measures the incremental revenue generated by SEO-driven organic traffic growth, relative to the cost of the SEO program. This calculator uses: ROI = ((Projected organic revenue − Current organic revenue − SEO cost) ÷ SEO cost) × 100. It accounts for only the incremental gain, not total revenue, which is the most accurate way to evaluate SEO's contribution.
Most businesses see positive ROI within 6–12 months of a well-structured SEO campaign. Months 1–3 cover technical fixes. Months 3–6 produce initial ranking improvements. By months 6–12, organic traffic typically grows enough to offset monthly investment. SEO compounds — ROI improves significantly after year one.
Positive ROI within 12 months is a reasonable benchmark. By month 24, well-maintained programs typically deliver 500–2,000% ROI depending on industry, average customer value and competition level. High-value professional services tend to see the strongest returns because customer value is high relative to organic acquisition costs.
Use your actual organic-specific conversion rate from Google Analytics (Acquisition → Traffic acquisition, filter by Organic Search). Australian averages: professional services 3–5%, healthcare 2–4%, home services 3–6%, eCommerce 1–3%, financial services 2–4%. Generic homepages average 0.5–1.5% — purpose-built landing pages perform significantly higher.
Google Ads delivers faster ROI because traffic is immediate. SEO requires a 3–6 month ramp-up. After 12–24 months, SEO typically delivers lower CPL because there is no ongoing cost per click once rankings are established. The two channels are complementary — paid search delivers immediate pipeline while SEO builds long-term compounding organic growth.
