- 01 Consent banners result in 30-60% of traffic being unmeasurable; if consent rate is below 60%, browser-side data alone is insufficient
- 02 Agent commerce bypasses the traditional funnel (landing > PDP > ATC > checkout) entirely; site-centric and agent funnels need separate KPI sets
- 03 Server-side tracking (sGTM or Cloudflare Zaraz) is now mandatory; pixels alone cannot compensate for consent and agent commerce data loss
- 04 Enhanced conversions provide cross-device attribution without cookie dependency using first-party data
- 05 Email-based identity resolution is the only reliable way to unify data from both channels (site + agent)
- 06 UCP event pipeline (checkout_session_created, order_created) must be prepared to capture agent commerce conversions
+ How does Consent Mode v2 affect KPIs?
Consent banners result in 30-60% of traffic being unmeasurable. GA4 session counts can be half the actual number. Since consenting users tend to be more engaged, conversion rates appear higher and bounce rates lower than reality. The dashboard paints an optimistic picture while actual performance may differ.
+ Why does agent commerce break KPI measurement?
In agent commerce, users can purchase without ever visiting the merchant's website. Traditional funnel metrics (sessions, cart abandonment, upsell) don't work on the agent surface. Even the conversion rate denominator is undefined because there are no sessions in the agent funnel.
+ Why has server-side tracking become mandatory?
Pixels miss a significant portion of events due to ad blockers, ITP/ETP, and consent restrictions. In agent commerce, browser-side measurement is completely bypassed. Server-side tracking (sGTM or Cloudflare Zaraz) addresses both problems.
+ What do enhanced conversions provide?
When a user converts, their email or phone number is hashed and sent to Google. Google matches these hashes with its own data to perform cross-device and cross-session attribution without cookie dependency. This is critical for attribution quality in the post-consent era.
