Ecommerce Core Web Vitals benchmarks by platform
BootLeads matched 1,497,780 active ecommerce storefronts to July 2026 Chrome UX Report data. CrUX covers 23.0% of the active six-platform set; among origins with all three metrics, 62.5% pass LCP, INP, and CLS.
All figures are monthly, all-device, and origin-level. They are not PageSpeed Insights mobile results, traffic estimates, or evidence that a platform causes performance outcomes.
What the snapshot shows
Read coverage and performance together before comparing platforms.
CrUX coverage ranges from 12.6% for Wix to 58.0% for Magento, so platform pass rates should not be compared without their sample coverage.
Within origins that have complete LCP, INP, and CLS data, the observed pass share ranges from 39.5% for WooCommerce to 81.9% for Shopify. This is descriptive, not causal.
A store passes only when at least 75% of eligible Chrome experiences are good for each of LCP, INP, and CLS. The displayed p75 values are coarse monthly summaries and are not used alone for the pass flag.
Core Web Vitals by ecommerce platform
Coverage is measured against active storefronts; pass share is measured only against origins with complete LCP, INP, and CLS data.

A single origin can miss more than one metric. Median p75 values describe the middle origin in each complete platform sample; the pass flag uses each metric's good-experience fraction, not the coarse p75 value alone.

Questions about the benchmark
Why can Shopify's pass rate look high?
The rate is calculated among Shopify origins with complete CrUX metrics, not every Shopify store in the database. The coverage and complete-sample counts are shown beside it.
Is this the same as Shopify's web performance report?
No. Shopify can report 30- or 90-day performance by device, page type, and events for a merchant's own store. This public benchmark uses one monthly all-device origin snapshot for cross-platform comparison.
Does passing Core Web Vitals guarantee better rankings?
No. Core Web Vitals are one part of page experience, and a passing result does not guarantee indexing, rankings, traffic, or conversions.
Methodology and limits
How to interpret this cross-platform snapshot without overstating it.
Denominators
Coverage uses all active supported storefronts. Pass rate uses only origins with complete LCP, INP, and CLS good-experience fractions.
Device and URL scope
This snapshot uses all-device origin-level CrUX metrics_summary data. It does not split phone and desktop experiences or individual URLs.
Interpretation
CrUX availability indicates that an origin met Chrome's reporting eligibility and sample requirements. It does not disclose traffic volume, search traffic, revenue, or ranking impact.
Platform comparison
Store maturity, themes, apps, hosting, geography, and audience mix can differ between platforms. These aggregates show observed associations and do not establish platform causation.
