Routing Meta and Facebook Ad Traffic with Clear Boundaries

Document how Facebook and Instagram placements open the campaign URL, including in-app browser steps and any tracker redirect. Use separate test notes for feed, story, and other materially different paths rather than assuming every click exposes identical context.

Preserve explicit campaign parameters and compare them with referrer and browser context. Treat referrer absence as a condition to understand, not automatic suspicion, because application and privacy behavior may legitimately remove it.

Check viewport layout, navigation, cookie behavior, redirects, and parameter retention in the actual in-app journey. A page that works in desktop Chrome can fail before the routing system receives a meaningful event on mobile.

Some verification traffic may resemble ordinary sessions while some real people use restricted networks or browsers. Combine evidence, maintain a safe fallback, and avoid claims that the system can know a visitor's employment or exact purpose.

Segment events by placement and campaign identifiers, then review unexpected destination ratios and repeated reasons. Re-run controlled visits whenever creative links, tracking settings, or the mobile landing experience changes.
