Frequently asked questions
How accurate is this calculator?
The math itself is exact given your inputs, but the output is only as accurate as the traffic, conversion rate and value estimates you provide — it is a projection tool, not a guarantee.
Where do I find my conversion rate?
Check Google Analytics or your ecommerce platform's reporting for the percentage of organic visitors who complete a purchase or form submission.
What does a negative ROI mean?
It means your projected revenue is lower than your investment at the current traffic and conversion levels — often expected in the early months of an SEO campaign.
