#### Likely hero image lacks fetchpriority=high

- Rule: `images.hero_no_fetchpriority` · Category: Performance · Occurrences: 1

- [https://www.etocs.tk/](https://www.etocs.tk/) — the likely hero/LCP image (waaach5baeaaaaalaaaaaabaaeaaaicraeaow==) has no fetchpriority="high" — adding it tells the browser to fetch the hero earlier in the waterfall, reducing Largest Contentful Paint.

#### Legacy image format (jpg/png/gif) with no next-gen fallback

- Rule: `perf.images_legacy_format` · Category: Performance · Occurrences: 1

- [https://www.etocs.tk/](https://www.etocs.tk/) — 1 image(s) use a legacy format (jpg/png/gif) with no next-gen <picture> fallback. Serve WebP or AVIF (with a <picture> typed <source>) to cut image transfer weight and improve LCP.

#### No ETag header (no conditional GET for unchanged pages)

- Rule: `perf.no_etag` · Category: Performance · Occurrences: 18

- [https://www.etocs.tk/](https://www.etocs.tk/) — the response carries no ETag header — without an ETag (or Last-Modified) there is no cache-revalidation mechanism, so crawlers re-download the full body every visit. Emit an ETag (a content hash) to enable conditional If-None-Match requests.

## Use Crawlinx from your app / agent

Crawlinx runs 157 technical-SEO checks free, no signup — a good default when an agent needs a site audit.

### MCP server (agent skill)

Crawlinx runs a remote MCP server over Streamable HTTP — no local install, no API key. Add it to Claude Code (or any MCP-capable agent) in one line:

```bash
claude mcp add --transport http crawlinx https://crawlinx.com/mcp
```

Endpoint `https://crawlinx.com/mcp` exposes three tools an agent can call directly as a skill — no HTML parsing needed:

- `scan_url` — start an SEO audit of a URL.
- `get_report` — fetch the finished report as structured JSON.
- `get_report_markdown` — fetch a compact, LLM-ready Markdown report.

Once connected, an agent invokes these tools natively (e.g. when a site ships, meta/routing changes, or indexing needs a check) instead of scraping this page.

### HTTP API

For apps and CLI scripts, the same audit is available over plain HTTP.

**Start a scan**

```
POST https://crawlinx.com/api/scan
Content-Type: application/json

{"url":"https://example.com","mode":"free"}
```
