Frequently asked questions

How does the projection work?

It’s a marketing funnel: your monthly visitors convert to leads at your website conversion rate, leads convert to customers at your sales close rate, and each customer is worth your average customer value. Multiply through and you get projected monthly revenue.

What conversion rates should I use?

Website (visitor → lead) conversion is often 2–10% depending on the offer; sales (lead → customer) close rates vary widely by industry. Use your own analytics where possible — even rough numbers give a useful estimate.

What’s the difference between ROI and ROAS?

ROAS is revenue ÷ cost (e.g. 6×) — gross revenue per rupee spent. ROI is (revenue − cost) ÷ cost × 100 — the net profit as a percentage. A 6× ROAS equals a 500% ROI.

How do I calculate SEO ROI?

SEO ROI is (revenue from SEO − cost of SEO) ÷ cost of SEO × 100. This SEO ROI calculator does it for you: enter your traffic, conversion rates, average customer value and SEO investment, and it returns your projected return on investment as a percentage.

Is this SEO ROI calculator free to use?

Yes — this online SEO ROI calculator is completely free with no sign-up. Use it to forecast the return on investment of your SEO or content marketing campaigns before and after you spend.

How long does it take to see SEO ROI?

SEO is a long-term investment — most campaigns take 4 to 12 months to show meaningful return as rankings and traffic build, then compound over time. This calculator projects the return once your traffic and conversion assumptions hold, so revisit it as your real numbers come in.

What's a good ROI for SEO?

Because SEO traffic is 'owned' and compounds, mature SEO often delivers a very high ROI (several hundred percent) compared to paid ads that stop the moment you stop paying. Any positive ROI where revenue exceeds your SEO spend is worthwhile — this tool shows the exact percentage.

Is my data sent anywhere?

No. Everything is calculated in your browser with JavaScript — nothing you enter is uploaded.
