Billboards.lk district planning guide
Build an outdoor campaign around Colombo.
Colombo is a practical layer for comparing towns, routes and audience movement within one district. Planning begins with the campaign audience and geographic role, then moves to suitable routes, formats, timing and verified inventory—not unqualified assumptions about coverage.
Connect meaningful journeys
Review approaches, town connections and repeated audience movements. The planning unit should reflect how people travel, not simply the administrative boundary.
Confirm viable media
Static and digital opportunities are checked for current availability, viewing context, dimensions and operational requirements before recommendation.

Managed execution
