Return on SEO investment from traffic value. The SEO ROI Calculator takes annual seo investment, extra organic visits per month, conversion rate, revenue per conversion, gross margin and returns seo roi (profit basis) plus annual revenue from the traffic, annual conversions, gross profit after seo cost. Results update as you type, and the formula is shown under the result so you can repeat it in your own spreadsheet.
Marketing metrics are most useful as trends and comparisons between channels. Measure every campaign the same way, over the same period, and judge it against your gross margin rather than against revenue alone. Use the worked example below to check the maths against your own figures.
How the SEO ROI Calculator works
SEO is judged on the traffic it adds over time. Value the extra visits by what they convert into, at your margin, and compare with the yearly investment; results usually lag spend by six to twelve months.
Worked example
With the example values (annual seo investment of $30,000, extra organic visits per month of 20000, conversion rate of 2%, revenue per conversion of $80, gross margin of 50%), the seo roi (profit basis) is 540%; annual revenue from the traffic $384,000.00, annual conversions 4,800, gross profit after seo cost $162,000.00. Change any figure above and the result updates immediately; use Copy results to paste the summary into a note or email.
