Sessions sourced from analytics sibling if connected; else Jetpack Stats fallback. Below 1.5% on a Woo store usually = checkout / page-speed issue, not traffic. ## At a glance > Orders divided by sessions. The funnel-health number for Woo. Below 1.5% on a Woo store usually signals a checkout, page-speed, or trust-friction issue, not a traffic problem. | | | | ------------------------------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **What it counts** | `COUNT(orders WHERE status IN ('completed', 'processing')) / COUNT(sessions)` x 100. Sessions are sourced from a connected analytics integration (GA4, Jetpack Stats, or Matomo plugin); orders come from the Woo REST API. | | **REST API endpoint** | Orders: `GET /wp-json/wc/v3/orders` filtered by status and date. Sessions: GA4 `sessions` metric, or Jetpack Stats `views`, or Matomo `nb_visits`. | | **VAT / tax treatment** | Not applicable, this is a count ratio. | | **Status filter** | Numerator is `completed + processing` (the realised-revenue orders). Denominator is all sessions in the window. | | **Shipping / discounts** | Not applicable. | | **Refunds** | Not deducted, refunds happen post-conversion. | | **Cancelled / failed orders** | Excluded from the numerator, customers who attempted checkout but failed do not count as "converted". | | **Currency** | Currency-agnostic ratio. | | **Channels / sources** | Not filtered. The denominator measures **all** sessions on the storefront; the numerator counts every payment channel. POS plugin orders are excluded from the numerator (no web session) which means heavy POS stores see this card under-report by 5-10%. | | **Self-hosted vs managed-Woo** | Self-hosted on slow shared hosting structurally suppresses conversion (page-speed correlation; every 100ms of TTFB drops conversion \~1%). Managed-Woo on enterprise-grade hosts shows higher baseline. | | **Session source dependency** | If GA4 is connected, GA4 sessions are used. If only Jetpack Stats, fallback. If neither, the card cannot compute and shows "no data". | | **Time window** | `30D vsP` | | **Alert trigger** | `<1.5%` (Tier-1 Woo baseline) | | **Roles** | owner, marketing | ## Calculation Calculated automatically from your WooCommerce data. See the At a glance summary above for what the metric tracks and the worked example below for a typical reading. ## Worked example A UK fashion brand on self-hosted Woo with GA4 connected. The 30-day window covers 14 Mar 26 to 12 Apr 26. | Metric | Value | Source | | --------------------------------- | --------- | ------------------- | | Sessions (GA4) | 142,400 | GA4 sessions metric | | Orders (`completed + processing`) | 2,152 | Woo REST API | | **Conversion Rate** | **1.51%** | Computed | Versus prior 30D where the rate was 1.78% (2,210 / 124,200). The card flags a -0.27 ppt drop and the rate is right at the \<1.5% alert threshold. Four observations: 1. **Sessions grew but orders did not.** Sessions up 14.7%, orders down 2.6%. The funnel got less efficient. Common cause on Woo: a recent theme or page-builder update added 200ms+ of TTFB (pre-fix the host was at 800ms, now at 1.05s). Pair this card with [Pagespeed Cart Loss](/nerve-centre/kpi-cards/woocommerce/pagespeed-caused-cart-abandonment-loss) for the speed-correlation view. 2. **Self-hosted server slowness is a structural drag.** This brand's Bluehost host averages 1.0s TTFB on the cart page. A 200ms reduction (achievable with a CDN like Cloudflare or a host upgrade to managed-Woo) would lift conversion by approximately 2%. The merchant currently leaves about 4-6 orders / month on the table for every 100ms of avoidable TTFB. 3. **GA4 is the trustworthy session source on Woo.** Jetpack Stats undercounts compared to GA4 because it does not track ad-blocked sessions either, but uses a different sampling model. If you switched the session source mid-period, conversion rates appear to jump artificially. 4. **POS orders are missing from the numerator.** This brand runs occasional pop-up POS events (\~30 orders/month). Those orders have no web session, so they do not appear in the numerator. The headline 1.51% is the **web-only** conversion rate; the merchant's blended number across all channels would be slightly higher. ## Sibling cards merchants should reference together | Card | Why pair it with Conversion Rate | | ---------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------ | | [WC Total Orders](/nerve-centre/kpi-cards/woocommerce/total-orders) | The numerator. Always check the absolute number on small samples. | | [WC Total Revenue](/nerve-centre/kpi-cards/woocommerce/total-revenue) | Conversion times AOV times sessions = revenue. Read together for the full picture. | | [WC Failed Order Rate](/nerve-centre/kpi-cards/woocommerce/failed-order-rate) | A spike in failed orders shows up as a conversion drop first. | | [WC Pagespeed Cart Loss](/nerve-centre/kpi-cards/woocommerce/pagespeed-caused-cart-abandonment-loss) | The speed-conversion correlation. Self-hosted Woo brands almost always have headroom here. | | [BC Channel Conversion Rate](/nerve-centre/kpi-cards/bigcommerce/conversion-rate-by-channel) | Cross-platform peer for agencies. | | [Shopify Conversion Rate](/nerve-centre/shopify/ecommerce_conversion_rate) | SaaS-platform peer. | ## Reconciling against the vendor's own dashboard **Where to look in WooCommerce Admin:** WooCommerce does not ship a native conversion-rate report. The closest views: * [WP Admin → Analytics → Overview (WC 4.0+)](/wp-admin/admin.php?page=wc-admin) shows orders alongside *Visitors* if a connected analytics integration is configured. * [WP Admin → Jetpack → Stats](/wp-admin/admin.php?page=stats) gives session counts; divide by Woo orders manually. * GA4 → Reports → Engagement → Pages and screens for sessions; cross-multiply against Woo orders. **Why our number may legitimately differ from your manual calculation:** | Reason | Direction of divergence | | ------------------------------------------------------------------------------------------------------------------------------------------------- | ---------------------------------------- | | **Session source mismatch**. GA4 vs Jetpack Stats vs Matomo each count sessions differently (timeout windows, bot filters, sampled vs unsampled). | Either | | **Time-zone**. WP-site timezone for Woo vs reporting-timezone for analytics. | Boundary effects | | **Self-hosted server uptime**. During outages, sessions are zero (no pages loaded), but the analytics integration may sample differently. | Self-resolves | | **Plugin-version compatibility**. Some caching plugins serve cached pages without firing the analytics tag, undercounting sessions. | Ours higher than analytics-derived rates | | **Multi-currency**. Currency switches can fire duplicate session events on some plugins. | Either; investigate per-merchant | **Cross-connector reconciliation:** | Card | Expected relationship | | -------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------ | | [`google_analytics.ga_ecommerce_conversion_rate`](/nerve-centre/google_analytics/ga_ecommerce_conversion_rate) | GA4 rate \<= this card's rate (GA4 misses 10-25% of orders due to ad blockers; numerator under-reports more than denominator). | ***

## Known limitations / merchant FAQs **Self-hosted vs managed-Woo, does it affect conversion rate?** Yes, structurally. Self-hosted Woo on slow shared hosting has higher TTFB, which suppresses conversion. Every 100ms of TTFB drop is \~1% conversion lift. Managed-Woo (Pressable, Kinsta, Woo.com Cloud) typically runs 200-400ms TTFB; budget hosting (Bluehost, GoDaddy shared) runs 800-1,500ms. **Status-filter selection, why exclude `on-hold`?** On-hold means BACS or bank-transfer payment-pending. From a conversion-rate perspective the customer "converted" (placed an order). But excluding it follows the convention that conversion = revenue-realised, BACS may never settle. If you want to count BACS as a conversion, the rate would be \~5-10% higher. **Refund-object accounting, does it affect conversion rate?** No, conversion is pre-refund. Refunds happen after conversion. **Plugin-induced data shape variance, what should I watch?** * Caching plugins (WP Rocket, W3 Total Cache) serve cached pages without firing GA4 tags by default; configure them to bypass cache for logged-in users and dynamic pages. * AMP plugins use a different page set; sessions split between AMP and non-AMP versions. * Multi-currency plugins fire spurious session events on currency switch; configure the plugin to suppress. **Multi-currency configuration, does it affect conversion rate?** Slightly. EU customers face heavier 3DS friction at payment time, so EU traffic mix structurally lowers conversion. Per-currency or per-country breakdowns are on the roadmap. **Why does WooCommerce and Stripe disagree?** Stripe does not measure sessions, only payment attempts. Stripe-derived conversion (Stripe charges / Stripe Elements page views) is a different metric. Use this card for the funnel-health view and Stripe's view for the payment-step efficiency view. **Today is jumpy, why?** Sessions and orders both arrive at different rates through the day. Today's conversion rate is meaningless until end-of-day. Use 7D / 30D rolling. **Sync-lag from self-hosted server slowness, can it cause false drops?** Yes. A 6-hour host outage means 0 sessions and 0 orders during the outage, but the post-outage period sees a flood of cached-but-now-loaded sessions, which depresses the rate temporarily. Self-resolves within 24-48 hours. **My WP Admin shows different numbers, debug:** 1. Confirm session source (GA4 vs Jetpack vs Matomo) and ensure the same source is used in both views. 2. Match the date range exactly. 3. Match the order status filter. 4. Confirm caching plugin is not blocking the analytics tag. *** ### Tracked live in Vortex IQ Nerve Centre *Conversion Rate* is one of hundreds of KPI pulses Vortex IQ tracks across WooCommerce and 70+ other ecommerce connectors.
