Paid to Organic Traffic Ratio
The proportion of your website traffic that comes from paid channels versus organic channels.
Formula
Why it matters
A highly paid-dependent traffic mix means CAC is vulnerable to ad platform changes, iOS privacy updates, and rising CPCs. As organic grows relative to paid, blended CAC falls and the business becomes more resilient.
How to improve Paid to Organic Traffic Ratio
Invest in SEO and content consistently over 12–24 months, build email list to own a direct channel, and create referral programs that generate organic word-of-mouth.
A healthy mature business targets 1:3 or better (1 paid visitor per 3 organic visitors). Early-stage: often 2:1 paid-heavy is normal.

Why does the paid-to-organic ratio matter for investors?
Investors evaluate this ratio as a proxy for CAC sustainability. A business 90% dependent on paid traffic faces significant CAC risk from platform changes. A business with strong organic traffic has a more defensible and lower-cost acquisition model.
