Frequently Asked Questions
How do you calculate SEO ROI?
SEO ROI = (Revenue from Organic Traffic - SEO Investment) / SEO Investment × 100. This calculator estimates revenue from organic traffic using your conversion rate and average deal value, then projects growth at 2x, 3x, and 5x traffic multipliers.
What is a good SEO conversion rate?
The average organic search conversion rate is around 2-3% across industries. E-commerce tends to sit around 1.5-2%, while B2B services can reach 3-5%. This calculator defaults to 2% but you should use your actual conversion rate from Google Analytics for accurate projections.
How long does it take to see ROI from SEO?
Most businesses start seeing measurable ROI from SEO within 6-12 months. The exact timeline depends on your starting position, competition level, and the quality of your SEO strategy. Unlike paid ads, SEO compounds over time — the ROI typically improves month over month.
Is SEO more cost-effective than Google Ads?
In most cases, yes. Organic search delivers a lower cost-per-acquisition over time because you're not paying per click. While SEO requires upfront investment, the traffic it generates doesn't stop when you stop spending. This calculator includes a CPA comparison so you can see the difference for your specific numbers.
