How to Calculate SEO ROI
Search Engine Optimization (SEO) is one of the most powerful digital marketing channels, but measuring its Return on Investment (ROI) can sometimes be elusive compared to paid advertising. Unlike PPC where costs are per-click, SEO costs are often time-based or retainer-based, making the calculation distinct.
Using the SEO ROI calculator above, you can determine if your current strategy is profitable. Understanding these metrics is crucial for justifying marketing budgets and scaling your organic search efforts.
The SEO ROI Formula
To calculate the return on investment for your SEO campaigns, we use a standard financial formula adapted for digital marketing metrics:
ROI = ((Total Revenue from SEO – Cost of SEO) / Cost of SEO) × 100
However, to get the "Total Revenue" figure, we first need to break down the funnel:
- Estimated Traffic: The number of visitors landing on your site from organic search.
- Conversions: Traffic × (Conversion Rate / 100).
- Revenue: Conversions × Average Order Value (AOV).
Example Calculation
Let's look at a realistic scenario for an e-commerce website:
- Monthly Organic Traffic: 10,000 visitors
- Conversion Rate: 2% (0.02)
- Average Order Value: $100
- Monthly Agency/Tool Cost: $5,000
First, we calculate revenue: 10,000 visitors × 2% = 200 sales. 200 sales × $100 = $20,000 Revenue.
Next, we calculate profit: $20,000 Revenue – $5,000 Cost = $15,000 Net Profit.
Finally, the ROI: ($15,000 / $5,000) × 100 = 300% ROI.
This means for every $1 you spend on SEO, you are getting $4 back (your dollar back plus $3 in profit).
What is a Good SEO ROI?
While benchmarks vary by industry, a ratio of 5:1 (400% ROI) is widely considered excellent in digital marketing. However, because SEO has a compounding effect (content written today drives traffic for years), even a lower initial ROI can be acceptable in the early stages of a campaign. Over time, as traffic grows without a proportional increase in costs, your SEO ROI should trend upward significantly.
