# PageSpeed

Integrated performance check that measures how fast your site loads for real users. Runs on demand from hPanel, reports Core Web Vitals, and surfaces concrete improvements.

## What it measures

* **Largest Contentful Paint (LCP)** — when the main content becomes visible
* **Cumulative Layout Shift (CLS)** — visual stability while the page loads
* **Interaction to Next Paint (INP)** — how snappy the page feels when clicked or typed into
* **Time to First Byte (TTFB)** — how fast the server starts responding
* **Total page weight** — HTML, JS, CSS, images, fonts

Scores are reported separately for mobile and desktop.

## Run a test

1. Open your website dashboard in hPanel.
2. Click **PageSpeed** (sometimes grouped under **Performance**).
3. Click **Run test**.

Results appear in under a minute.

## Read the results

Each metric is graded:

| Grade                 | Meaning                                              |
| --------------------- | ---------------------------------------------------- |
| **Good**              | Meets Google's Core Web Vitals thresholds            |
| **Needs improvement** | Borderline — affects SEO under real-world conditions |
| **Poor**              | Fails the threshold — high-priority to fix           |

Below the metrics, PageSpeed lists actionable recommendations ordered by estimated impact — e.g., "Serve images in next-gen formats", "Reduce unused JavaScript", "Enable text compression".

## Applying fixes

Many recommendations map to other Hostinger features:

* **Cache / compression** → [Cache](/websites/cache.md)
* **Global asset delivery** → [CDN](/websites/cdn.md)
* **Image optimization** → Hostinger's auto-optimization (enable in **Performance** settings)
* **PHP version** → [PHP Configuration](/websites/php.md) (newer versions are faster)

Some require code changes — the report links to the specific file or resource.

## Notes

* Results vary by network conditions, time of day, and visitor geography. One test isn't a trend — look at multiple runs.
* Lighthouse scores from different tools (Google PageSpeed Insights, WebPageTest) may differ from Hostinger's because of network profiles and thresholds.
