## How it calculates

The core formula is: Traffic Value = Monthly Organic Visits x Average CPC. This represents the equivalent PPC spend for your organic traffic volume. SEO ROI is calculated as: (Traffic Value x 12 - SEO Cost x 12) / (SEO Cost x 12) x 100, expressing the percentage return on your annual SEO investment. Revenue from organic traffic is calculated as: Monthly Visits x Conversion Rate x Average Order Value, giving you the estimated monthly revenue attributable to organic search. Cost per acquisition divides your monthly SEO spend by the number of monthly conversions (visits x conversion rate) to show what each organic customer costs you.

## Who should use this

SEO professionals justifying budgets to clients or leadership, marketing managers comparing organic vs paid channel efficiency, startup founders evaluating whether SEO investment is worthwhile, content marketers quantifying the business value of organic rankings, and agency teams building SEO proposals or performance reports.

## Worked examples

Example 1: A SaaS company gets 25,000 monthly organic visits with an industry CPC of $3.00. Traffic Value = 25,000 x $3.00 = $75,000/month. They spend $3,000/month on SEO. SEO ROI = ($75,000 x 12 - $3,000 x 12) / ($3,000 x 12) x 100 = ($900,000 - $36,000) / $36,000 x 100 = 2,400%. With a 2.5% conversion rate and $150 average order, monthly organic revenue = 25,000 x 0.025 x $150 = $93,750.

Example 2: A legal services firm receives 5,000 monthly organic visits at a CPC of $7.00. Traffic Value = 5,000 x $7.00 = $35,000/month. With $5,000/month SEO spend, ROI = ($420,000 - $60,000) / $60,000 x 100 = 600%. At 1% conversion rate and $2,000 case value, organic revenue = 5,000 x 0.01 x $2,000 = $100,000/month.

Example 3: An eCommerce store has 50,000 monthly organic visits at $1.50 CPC. Traffic Value = 50,000 x $1.50 = $75,000/month. With $2,000/month SEO spend and 3% conversion rate at $45 average order, organic revenue = 50,000 x 0.03 x $45 = $67,500/month. Cost per acquisition = $2,000 / 1,500 conversions = $1.33 per customer.

## Limitations

This calculator uses a single average CPC value, while in reality different keywords carry vastly different CPC rates. Branded keywords often have low CPCs but high volume, which can inflate perceived traffic value. The tool assumes every organic visit would otherwise require a paid click, which overstates value since some users would find your site through other channels. Conversion rate is applied uniformly across all organic traffic, but actual conversion rates vary significantly by landing page, keyword intent, and user segment. The calculator does not account for organic traffic growth or decline trends over the projection period.

## FAQs

**Q:** How do I find my average CPC?


**A:** Check Google Ads Keyword Planner, Ahrefs, SEMrush, or similar tools for your target keywords. The industry presets in this tool provide reasonable starting estimates based on published averages.


**Q:** Why is my SEO ROI so high?


**A:** Organic traffic value often significantly exceeds SEO investment because SEO compounds over time. Unlike PPC where you pay for every click, SEO builds lasting visibility. High ROI percentages in the hundreds or thousands are common for established organic traffic.


**Q:** Should I use this to compare SEO vs PPC?


**A:** This tool is best used to quantify SEO value in terms stakeholders understand (equivalent ad spend). Direct SEO vs PPC comparisons should also consider factors like conversion rate differences between channels, time to results, and long-term sustainability.


**Q:** What conversion rate should I use?


**A:** Industry averages range from 1-5% for most websites. eCommerce sites typically see 2-3%, SaaS around 2-5%, and lead generation 3-8%. Use your own analytics data for the most accurate results.
