What’s the hardest part about scaling pay-per-call campaigns?

Hey everyone,

Running a campaign is one thing… but scaling it profitably is a completely different game.

I’ve noticed that once you try to scale, a lot of issues start showing up:

• Call quality drops
• Buyers start rejecting more calls
• Tracking becomes messy across multiple sources
• Margins shrink fast

So I wanted to ask the community:

• What’s been your biggest bottleneck while scaling pay-per-call?
• Is it traffic, call quality, buyers, or tech?
• How are you handling call tracking + routing when volume increases?

Also, are you using any platforms or tools that actually help in scaling smoothly?

Would love to hear real strategies and experiences from people who’ve scaled campaigns successfully 👇
