ANGA — bilingual site and attribution

Context

Marketing spend was visible in four tools and nowhere as a single visitor journey. Arabic/English content and WhatsApp close the sale off-site, which breaks naive pageview attribution.

Architecture

Laravel owns the request. Locale and content are first-class. Attribution IDs travel into WhatsApp so a conversation can still be tied to the session that produced it.

Decisions

Locale is routing, not CSS

Arabic/English is a content and URL concern. RTL is a consequence, not a theme toggle.

Carry IDs off-site

WhatsApp is part of the funnel. If the click ID dies at the button, attribution is theatre.

One event vocabulary

GA4, Meta, and internal conversions share names. Three taxonomies is how numbers stop matching.

When it fails

Condition	Detection	Response
Consent / pixel blocked	Tag load failure	First-party event still records; ads tags degrade
Locale mismatch	Accept-Language vs URL	Honor explicit URL; do not silent-swap content
WhatsApp ID stripped	Outbound URL audit	Fail the handoff link build; do not send a bare wa.me

Infrastructure

WhatsApp deep links
cache headers
uptime checks

Outcome

A site where bilingual content and paid acquisition report against the same visitor identifiers, including WhatsApp.

Current state

Live. Attribution and performance work continue on the same request path.
