Advertisement Detail Page

This document describes the /advertisement/[id] detail page (when data has loaded) and how to use it for operational checks.

In development, an invalid or missing ID may only show a loading message ("Loading data..."). In production, a valid ID will reveal all sections.

1. Expected Section Layout (Roadmap Oriented)

Section	Contents	Purpose
Basic Info	Title, Description, Type, Status, Display Order	Quick identification & prioritization
Content Info	Image thumbnail, Link URL	Verify asset health & destination
Schedule Info	Start, End, (future Remaining days)	Detect approaching expirations
Targeting Info	Language, Device, Countries	Validate exposure scope
Action Panel	Edit, Activate/Deactivate, (future) Delete	Routine lifecycle adjustments

Item	Question
Link Validity	Does the URL resolve correctly?
Image Quality	Proper resolution/ratio without heavy load?
Schedule Integrity	End date not in the past?
Target Accuracy	Confirmed exposure in test user session?
Duplication	Redundant similar active ads?

Planned additions as sub-sections or cards:

Until released, interim measurement approach:

Symptom	Possible Cause	Resolution
Loading never ends	Bad ID / network error	Verify ID, refresh
404 after click	Internal path typo	Edit and fix Link URL
Image missing	Upload failed / file removed	Re-upload new asset
Not displaying	Inactive status or out-of-range schedule	Re-check status/dates
