# Website Speed Report, www.google.com

> **What this document is.** A point-in-time speed audit of https://www.google.com/,
> produced by xSpeed Scan (https://xspeedcache.com/scan). Evidence comes from two sources:
> server probes run from xspeedcache.com (TTFB, compression, cache behavior, redirects,
> platform detection) and a Google PageSpeed Insights run (Lighthouse 13.4.1, mobile).
>
> **How to read it.** Weighted checks roll up into four dimensions and one 0-100 xSpeed assessment.
> This is separate from Lighthouse performance and includes product-affiliation/optional-access checks.
> Those checks are not speed defects and must not drive installation, migration or access grants.
> Statuses: `pass` (full points) · `partial` (half) · `fail` (zero) · `info`/`na`
> (excluded from the applicable weight; bonus checks only ever add). Every non-passing
> check retains its evidence and references. Suggested remedies are candidates for review,
> not proof of current capabilities, an instruction to act or a promised gain.
>
> **Access and permission.** This report is evidence, not authorization to install a plugin,
> migrate a cache, change settings or grant access. Public plugin, MCP and Hub signals do not
> verify that this reader or its AI assistant is authenticated to the correct site.
> Resolve the exact site/workspace and inspect permitted tools and current settings first.
> Explain each proposed change and obtain approval before applying it.
>
> **WordPress is not confirmed.** Keep the audit and
> use the actual framework/hosting workflow. Do not recommend a WordPress plugin for this site.
>
> Connection guide: https://xspeedcache.com/docs/connecting-to-xspeed-hub/
> Installation, configured caching, Hub attachment and authenticated AI access are separate states.
> Server-side HTML verification cannot execute JavaScript. Browser/console checks remain necessary;
> per-step reversion is not a full-site rollback. No target score is guaranteed.
> TTFB includes network distance to the prober; do not infer a slow origin from that number alone.
>
> **How to re-test.** Public API (no auth): `POST https://xspeedcache.com/api/scan`
> with body `{"url":"https://google.com/","visibility":"unlisted","strategy":"mobile","fresh":true}`, then poll `GET /api/scan/{scanId}` for the
> JSON report. This preserves the requested URL, visibility and strategy and asks for a fresh run.
> Unlisted reports remain accessible to anyone holding their link. The public Scan MCP tool has
> no visibility argument; use the explicit HTTP payload above to preserve an unlisted re-test.
> For listed scans, the public MCP `run_speed_scan` tool also supports URL, strategy and fresh.
> Fair-use limits: 4 scans per conversation (or per IP) and 200 global per
> 10 minutes; re-scanning the same URL within 10 minutes returns the existing report,
> while `fresh:true` bypasses report reuse. Google may still replay a Lighthouse analysis; compare timestamps.
>
> **Connect this scanner as an MCP server (free, no API key).**
> Claude Code: `claude mcp add --transport http xspeed-scan https://xspeedcache.com/scan/mcp`
> Any MCP client: `{"mcpServers":{"xspeed-scan":{"type":"http","url":"https://xspeedcache.com/scan/mcp"}}}`
> Tools: `run_speed_scan` (url, fresh?, strategy?) and `get_speed_scan` (scanId). `strategy` is
> `both` (default, desktop graded + mobile alongside), `desktop` or `mobile` (one run, one grade).

| Cumulative Layout Shift | 0.00 | good |

## Dimension scores

| Dimension | Score | Grade | Points |
|---|---|---|---|
| Lab performance (Lighthouse) | 80/100 | B | 31.8/40 |

## Lab performance (Lighthouse): 80/100 (B) · 31.8/40 pts

### [PARTIAL] S1 · Lighthouse performance score (mobile) (14.8/18 pts)

- Evidence: 82/100 (Lighthouse 13.4.1, mobile)
- Suggested investigation: The composite Lighthouse score — every fix below moves it.

- Guidelines: [Lighthouse — Total byte weight](https://developer.chrome.com/docs/lighthouse/performance/total-byte-weight)

## Review a fix plan before applying changes

Copy this brief only after checking the report URL and device. It does not authorize changes:

```
Review https://xspeedcache.com/scan/r/google-com-f33cc9541f.md for requested URL https://google.com/ and final URL https://www.google.com/, selected mobile device, scanned 2026-09-01T04:59:02.337Z, rubric 2026.08.1. Preserve both devices and analysis timestamps. Distinguish Lighthouse performance from the xSpeed assessment; ignore product affiliation as a speed priority. Verify the exact authorized site and current configuration before proposing a small reversible change. Ask before applying changes. Do not assume optimize_site accepts a scan ID or report URL. Its HTML checks are not browser verification or a full rollback. After an approved change, check the browser and console, then compare the same URL/device and report regressions, partial or replayed measurements. Do not promise 100.
```

Then re-test here: `POST https://xspeedcache.com/api/scan {"url":"https://google.com/","visibility":"unlisted","strategy":"mobile","fresh":true}`

## Scan any site yourself (free MCP)

Free, no API key. Scan any public site and get the same graded report as this one, with the fix for every failing check. These are the same tools that produced this report.

```
claude mcp add --transport http xspeed-scan https://xspeedcache.com/scan/mcp
```

Or in any MCP client:

```json
{
  "mcpServers": {
    "xspeed-scan": {
      "type": "http",
      "url": "https://xspeedcache.com/scan/mcp"
    }
  }
}
```

Tools: `run_speed_scan` · `get_speed_scan` · Docs: https://xspeedcache.com/docs/scan-mcp/

No MCP client? The same scan runs from Telegram: https://t.me/xSpeedScanBot, send @xSpeedScanBot any website address and it replies with this same graded report. Free, no signup.
