Understanding Your SEO ROI
Calculating the Return on Investment (ROI) for Search Engine Optimization is crucial for validating marketing budgets and strategizing future growth. Unlike paid advertising, SEO is a long-term investment that compounds over time.
How This Calculator Works
This tool uses your current performance metrics to forecast the financial impact of increased organic traffic. Here is a breakdown of the inputs:
- Current Monthly Traffic: The number of visitors currently landing on your site via organic search.
- Conversion Rate: The percentage of visitors who take a desired action (like filling out a form).
- Close Rate: The percentage of leads (conversions) that turn into paying customers.
- Customer Lifetime Value (LTV): The total revenue you expect from a single customer over the course of your relationship.
- Projected Traffic Increase: A conservative estimate of how much your traffic will grow due to SEO efforts (typically 10-50% in the first year depending on the strategy).
The Formula for SEO ROI
The core calculation for SEO ROI is: ((Net Profit from SEO) / (SEO Costs)) × 100.
To find the Net Profit, we first calculate the additional revenue generated by the increase in traffic, then subtract the cost of the SEO services. A positive ROI indicates that your strategy is profitable, while a negative ROI suggests that the generated revenue hasn't yet covered the investment costs—common in the early months of an SEO campaign.
Why LTV Matters
Many businesses underestimate SEO ROI because they only look at the first sale. By using Customer Lifetime Value, you get a more accurate picture of the long-term wealth generated by acquiring a new customer through organic search.
