# How to run a full site scan

> Grade your whole site — Core Web Vitals, caching, assets and platform — and get a ranked list of fixes with the points each one recovers.

A PageSpeed score tells you how one page rendered on one test machine. **xSpeed Scan** asks a broader question: across roughly twenty checks in four weighted areas, how well is this site actually set up? It returns one grade out of 100 and — more usefully — a ranked list of what to fix, each with the number of points it would recover.

> **Where to find it**
>
> 1. In your WordPress admin, click **xSpeed Cache** in the left menu.
> 2. In the xSpeed Cache sidebar, open the **Health & insights** group.
> 3. Click the **Speed Test** card, then the **xSpeed Scan** tab.
>
> *Shortcut: open `wp-admin/admin.php?page=xspeed#/insights/score/scan` directly.*
>
> ✅ This tab is part of **xSpeed Cache (Free)**.

1. **xSpeed Scan** — what the report covers.
2. **Visibility notice** — where the report will be published.
3. **Run a scan** — starts it; becomes **Scan again** once you have a report.

## Settings at a glance

This tab has no stored settings — it's one action and its result:

| Control | What it does |
| --- | --- |
| **Run a scan** | Grades the site and stores the report. **Scan again** once one exists. |
| **Dimension bars** | The four graded areas, each with points earned out of its weight. |
| **What to fix next** | Failed and partial checks, ranked by points recovered. |
| **Full report** | Opens the hosted report. |

## How it works

Press **Run a scan** and the engine grades your site across four weighted dimensions, taking roughly 20–60 seconds:

| Dimension | What it covers |
| --- | --- |
| **Core Web Vitals** | Measured loading behaviour — LCP, CLS, TBT and friends. |
| **Server & caching** | Whether caching is actually working at the origin. |
| **Assets** | Weight and delivery of CSS, JavaScript, images and fonts. |
| **Platform** | The underlying stack — PHP, server software, configuration. |

Each bar shows the points earned against that dimension's weight, so you can see which area is costing you most rather than just the total.

## Read this before your first scan

> ⚠️ **Your report is published publicly by default.** The card says so above the button, not buried after it: *"This report will be publicly visible at xspeedcache.com, listed under your domain."*
>
> The scan engine publishes every report it stores to a per-host feed that **anyone can enumerate by domain**. Connecting [xSpeed Hub](https://xspeedcache.com/docs/mcp-server/) keeps your reports unlisted; without it, a report for a client site is discoverable by that client's domain. Decide that before you run one, because the decision is made at scan time.

## It is not a second PageSpeed score

This is the distinction worth holding on to, and the panel is careful about it.

**A Lighthouse result is one check inside this scan — worth 18 of the 100 points.** The two numbers are on different scales and measure different things, so the card labels them separately — the scan's own score *out of 100*, and *Lighthouse performance, out of 100* with the device it measured — rather than presenting one as a version of the other.

So a site can grade well here and score moderately in Lighthouse, or the reverse. They are not in disagreement — they are answering different questions. Use [Speed test](https://xspeedcache.com/docs/external-score/) for the score Google ranks on; use this for whether the site is configured well.

> 💡 **A "partial scan" is not a failure.** If some checks can't run, the panel says *"Partial scan — some checks could not run, so the score covers less than the full rubric"* and the score covers less than the full 100. Treat that total as a floor, not a verdict.

## What to fix next

The ranked list is the point of the whole feature. Each entry carries:

- **Status** — whether the check failed outright or passed partially.
- **Evidence** — what the scan actually observed.
- **Remediation** — what to change.
- **Points recoverable** — how much the grade improves if you fix it.

Sorting by points recovered means you spend effort where it counts, instead of working down a list where a trivial item sits above a structural one. It pairs naturally with the recommendations on Health's [Overview tab](https://xspeedcache.com/docs/cache-diagnostics/): those read your xSpeed configuration, this grades the site as delivered.
