Alright, so here's my process, and it's pretty straightforward but kinda eye-opening every time. Started tracking weekly numbers across different campaigns and networks, just to see where the real juice is. So, last week I got these numbers: total spends 2k, leads 350, conversions 70, and the EPC on the main LP hit 0.4. Now, that sounds decent but digging into the backend, the CPL on some segments is way higher than I expected, like 30 bucks on some sources but only 10 on others. So, I run the numbers on the lander pages too, and I find that my top converting page only gets about 20% of total clicks but contributes 60% of the conversions. That's a clear sign I need to double down on the best LPs and cut the dead weight. I also look at the traffic sources, where the leads come from, and compare those to the backend quality. Some sources give me volume but crappy leads that ghost post sign-up, so I start dropping those or negotiate better margins. It's all about breaking down those stats objectively, not just chasing big numbers, but understanding where the real value is hiding. Nothing revolutionary but just staying disciplined with the data, that's how I optimize and don't get shaved.
