| Phone | €7-15 |
How to Use It
CPC is most valuable when paired with CSAT. However, optimising CPC in isolation leads to cost cutting that destroys experience. Instead, track CPC and CSAT together, and optimise for the ratio of satisfied customers per euro spent, not either metric alone.
Frequently Asked Questions
