I have 2 ads. Ad1 spent 170 EUR and Ad2 around 70 EUR.
Both in the same ad set.
Ad1 has 11.1 EUR CPL and Ad2 has 19 EUR CPL.
Ad1 has 0.78% CTR and Ad2 1.58% CTR.
From the beginning when I activated Ad2 it had incredible CTR. Which metric is better to follow? Also, I was thinking to check which one brought the most appointments but that's hard through GHL.
