Draw the global-versus-domestic channel boundary first
The scope lists every requested platform, account owner, billing owner, operator and data export. Google, Meta and TikTok work does not imply management of Naver, Kakao or another domestic ecosystem. Those channels enter scope only with verified access and a named qualified specialist.
Make Korean review part of conversion design
A Korean reviewer checks more than an advertisement. Search terminology, landing evidence, form fields, mobile usability and the language used after an enquiry all affect whether paid demand can convert. Each approval and response owner is recorded before the campaign opens.

Outbound demand for Bali or another Asian destination is reported by source market, travel dates, inventory and booking path. A campaign serving a business inside South Korea uses a different geographic and sales model. The two are not merged into a vague regional return figure.
