How to Calculate the ROI of SEO
Step 1: Determine Your Current Organic Traffic
Use Google Analytics or a similar tool to find your current monthly organic search traffic. Focus on non-branded search terms to isolate the impact of your SEO efforts.
Step 2: Estimate Traffic Increase
Based on your SEO strategy and historical data, estimate the percentage increase in organic traffic you expect to achieve. Be realistic – SEO is a long-term game.
Step 3: Calculate Conversion Rate
Divide the number of conversions from organic search by the total organic search visitors. For example, if you have 10,000 organic visitors and 250 conversions, your conversion rate is 2.5%.
Step 4: Determine Average Order Value (AOV)
Calculate your AOV by dividing total revenue by the number of orders over a specific period.
Step 5: Estimate Profit Margin
Factor in your costs to determine your profit margin percentage.
Step 6: Calculate SEO Costs
Sum up all costs associated with your SEO efforts, including staff time, agency fees, tools, and content creation.
Step 7: Put It All Together
Now, let’s use these metrics to calculate your SEO ROI:
- Additional Traffic = Current Traffic × Estimated Traffic Increase
- Additional Conversions = Additional Traffic × Conversion Rate
- Additional Revenue = Additional Conversions × Average Order Value
- Additional Profit = Additional Revenue × Profit Margin
- ROI = (Additional Profit – SEO Costs) / SEO Costs
Example Calculation
Let’s say:
- Current monthly organic traffic: 10,000 visitors
- Estimated traffic increase: 30%
- Conversion rate: 2.5%
- Average order value: $150
- Profit margin: 40%
- Monthly SEO cost: $2,000
Calculating:
- Additional Traffic = 10,000 × 30% = 3,000
- Additional Conversions = 3,000 × 2.5% = 75
- Additional Revenue = 75 × $150 = $11,250
- Additional Profit = $11,250 × 40% = $4,500
- ROI = ($4,500 – $2,000) / $2,000 = 125%
In this example, the SEO ROI is 125%, meaning for every dollar spent on SEO, the business gains $2.25 in profit.
Interpreting Your SEO ROI
- A positive ROI indicates your SEO efforts are profitable.
- The higher the percentage, the more efficient your SEO investment.
- If your ROI is negative, it’s time to reassess your strategy or give it more time (SEO often takes 3-6 months to show significant results).
Beyond the Numbers
While ROI is crucial, don’t forget about other SEO benefits:
- Increased brand awareness and credibility
- Long-term, sustainable traffic growth
- Improved user experience
- Competitive advantage in your industry
