Hey guys, i have been required to calculate CPA for SEO for a lead gen site. So the way i`m thinking about calculating is calculate the difference in YoY conversions with SEO spend e.g. lets say goal completions was 10, 000 in year 2019 and 18, 000 in year 2020, with $20, 000 invested into SEO. The difference is a 8, 000 increase. So then the SEO CPA would be total SEO spend $20, 000 / 8, 000 leads which is a $2.50 CPA. If you had to calculate CPA is that how you would do it?
