How do you track ROI when using native ads to promote affiliate services?

[Brajet]

I recently learned that native ads can be tricky when promoting offline services since tracking direct results isn't as straightforward as online sales.

I ran a few campaigns with clear calls to action and unique phone numbers to see if that would help measure interest.

I also tested using landing pages with booking forms to capture leads. Some campaigns generated calls and visits, though connecting those back to the ads took extra effort. I'm still figuring out the best way to link offline actions to native ad performance.
