PageSpeed audit

Overview

Every report includes a Google PageSpeed Insights audit of the store's homepage, providing Lighthouse scores across four categories. Use these to benchmark store performance, find optimization wins, or track SEO health over time when combined with monitoring.

Categories

Scores are returned as floats between 0 and 1 (multiply by 100 for the familiar 0-100 Lighthouse display). Individual audits include numeric values in milliseconds for metrics like largest-contentful-paint and total-blocking-time.

Accessing audit data

The full audit data is available via GET /api/pagespeed/:jobId, returning the raw PageSpeed Insights JSON. See the reports API for the full schema.

Tracking performance over time

Pair PageSpeed audits with store monitoring to track how a store's performance evolves across deployments. Every snapshot includes a fresh PageSpeed run, so you can graph LCP, CLS, and category scores over weeks or months.
