PageSpeed Insights
Run mobile Lighthouse audits from WordPress with plan-based daily quotas.
PageSpeed Insights tooling in the Cache Rocket WordPress plugin lets you queue a mobile Lighthouse audit for your site without leaving wp-admin. Scores and lab metrics help you validate the impact of warming, Managed CDN assets, Critical CSS, and image optimization—within a daily audit quota set by your plan.
Highlights
- One-click mobile PageSpeed from Media settings
- Lighthouse performance and related lab metrics
- Daily audit quotas on Starter and above
- Validate cloud optimization and warming changes
Measure what you ship
Optimization without measurement is guesswork. PageSpeed Insights gives you a repeatable lab check after you enable cloud image formats, Critical CSS, or LQIP—or after you expand warming coverage.
Audits consume your daily PageSpeed quota. When the quota is exhausted, new runs wait until the next day or a plan upgrade.

Frequently asked questions
- Is this a field-data Core Web Vitals report?
- PageSpeed Insights includes lab (Lighthouse) data from the queued audit. Treat it as a diagnostic tool, not a substitute for CrUX field data.
- Which plans include PageSpeed?
- Starter and above include PageSpeed scores with a daily audit cap that increases on higher tiers.
- Does an audit use Managed CDN bandwidth?
- PageSpeed audits are measurement jobs; they do not upload assets to Managed CDN. Image, Critical CSS, and LQIP jobs are what consume CDN bandwidth quotas.
