SEO ROI Calculator
Plug in your target monthly organic sessions, expected visitor-to-lead and lead-to-customer conversion rates, average contract value, and SEO retainer cost. Pick your currency. The calculator shows projected monthly customers, MRR, total programme revenue and ROI ratio. Useful for board-deck conversations and SEO budget justification.
B2B SaaS visitor-to-lead conversion typically runs 1-3% on well-optimised landing pages. Bottom-of-funnel intent queries (e.g. 'best B2B SEO agency') can hit 3-5%. Mid-funnel content (blog posts, calculators) typically converts 0.5-1.5% to lead. Top-of-funnel awareness content converts under 0.5%.
Qualified MQL to closed customer typically runs 15-30% for B2B SaaS, depending on segment. Self-serve SaaS often closes 25-40% of trial signups. Enterprise SaaS with sales-led motion often closes 15-25% of SQLs. Mid-market lands around 20-25%.
The calculator gives you a directional projection, not a guarantee. Real ROI depends on your specific market, ICP fit, content quality, search intent match, and competitive landscape. Use the projection as a sanity check for SEO budget conversations — not as a contractual commitment.
For B2B SaaS, expect ranking movement within 30-60 days, meaningful organic traffic within 90-120 days, and pipeline-attributable revenue within 4-6 months. Compounding really kicks in around month 9-12 as topical authority and link equity accumulate.
