Practical, no-fluff guides on attribution, chat commerce and AI for performance teams. How tracking really works, where funnels leak, and what to do about it.
Meta rejects an event_time over 7 days old and fails the whole request. Google keeps a gclid 90 days. TikTok gives offline events 28. Each vendor quoted, with what none of them publish.
Where the click identifier appears in the referral object, how to return it unhashed through the Conversions API, when it is missing, and what Meta does not document about it.
Nothing is broken and nothing is blocked. The pixel is JavaScript reading cookies on your domain, and the person left the browser. The documented chain, step by step.
Telegram allows 64 characters from A-Z, a-z, 0-9, underscore and hyphen. That is 48 bytes. Why a Meta click ID does not fit, and what to carry instead.
ChatMemberUpdated field by field, per-visitor invite links, join requests, the joins that can never be attributed, and why Telegram Ads issues no click ID.
Only WhatsApp gives you a real click ID. Messenger and Instagram give you ref, ad_id and a scoped user ID. A field-by-field comparison of all three.
Twenty-nine terms defined from primary vendor documentation: fbclid, gclid, ttclid, ctwa_clid, CAPI, postbacks, deduplication, event_id, deep links and start parameters.
Why the browser pixel misses conversions, how server-side events fix it, and how deduplication and match quality actually work.
The attribution trail dies the moment a lead opens Telegram. Deep links, start parameters and postbacks bring it back.
Message categories, template messages and per-country rates, and how to budget for WhatsApp campaigns without nasty surprises.
Ad blockers, ITP and shrinking cookie lifetimes are eating your data. Where pixels still help, and where the server has to take over.
Click IDs, registration and FTD events, Cellxpert-style networks and how to reconcile postbacks against what you actually get paid.
Better conversion signals, placement hygiene, creative cadence and kill rules. Levers that move ROAS before you touch the budget slider.
