Core Web Vitals Benchmarks for Magento Stores (2026 Data)

Public Magento Core Web Vitals tables often put Adobe Commerce in the middle of the ecommerce pack: roughly four to five in ten Magento origins pass all three vitals on mobile CrUX, depending on who measured. Open a multi-page Lighthouse sample on real Magento storefronts and the picture changes around Largest Contentful Paint. Mobile Performance averages sit near the high 50s, lab LCP medians stretch past Google's 2.5 s good line, and unused JavaScript shows up on almost every domain.

Both views can be true. Population CrUX describes popular origins under field conditions. Portfolio monitoring needs URL-level and multi-page evidence, because catalog templates, checkout, and extension scripts decide what shoppers feel.

We published a reproducible sample from Magento users we analyse in Apogee Watcher after a strong-signal platform check (n = 76 stores; median 13 analysed pages per store). Store-level lab averages, not single-URL CrUX p75s:

• Median mobile Performance about 58; desktop about 75.

• Lab LCP remains the hard problem across category, PDP, cart, and checkout templates.

• Unused JavaScript on 72 of 76 stores in the sample.

• Attention-Free Score near 0% means almost every completed lab test failed at least one gate (usually Performance ≥ 90 and/or LCP ≤ 2.5 s).

Fix LCP candidates, extension weight, and caching on money-path templates before treating a platform migration as the first move. Re-measure the same URL set after each change.
