Confirm period boundaries and filter settings match the Vortex IQ profile to reconcile cleanly. **Why the Vortex IQ value may legitimately differ:** | Reason | Direction | What to do | | ---------------------------------------------------------------------------------------------------------- | --------- | ------------------------ | | **Period boundary.** Vortex IQ uses 30-day rolling by default; vendor dashboards may use calendar periods. | Variable | Match the period range. | | **Time zone.** Vendor uses account time zone; Vortex IQ aligns to merchant reporting time zone. | Marginal | Confirm time zone match. | | **Filter scope.** Profile-level filters (channel, B2B, test orders) may narrow the Vortex IQ view. | Variable | Match filter settings. | **Cross-connector reconciliation:** complement with sibling cards in the same category for the full diagnostic picture. For divergence investigations, use Vortex Mind. ## Known limitations / merchant FAQs **Q: How often does Health Score Trend update?** The card refreshes on the standard data refresh (typically every 30-60 minutes for live integrations). For real-time signals, force a manual refresh from the dashboard. **Q: Why does my Website Performance (PageSpeed + CrUX) dashboard show a different number?** The most common reasons are period-boundary differences (Vortex IQ uses 30-day rolling vs vendor's calendar months), time-zone alignment, and filter scope (profile-level vs vendor's all-account view). Match these settings before assuming a real divergence. **Q: How does Health Score Trend relate to other executive overview metrics?** Track this card alongside the siblings listed above to build a complete picture. Single-metric reads can mislead; the diagnostic value is in the cross-reference. **Q: Can I customise the alert threshold?** Yes, alert thresholds are configurable per profile in the Alert Rules tab. Adjust to match your business baseline rather than relying on the generic default. *** ### Tracked live in Vortex IQ Nerve Centre *Health Score Trend* is one of hundreds of KPI pulses Vortex IQ tracks across Website Performance (PageSpeed + CrUX) and 70+ other ecommerce connectors.
