- [https://diemel.renaturiert.org/](https://diemel.renaturiert.org/) — no llms.txt found at the site root — add one so AI agents get a curated site summary

#### Low text-to-HTML ratio

- [https://diemel.renaturiert.org/renaturierung](https://diemel.renaturiert.org/renaturierung) — 3.3%

#### Images without width/height (layout shift / CLS)

- Rule: `images.missing_dimensions` · Category: Images · Occurrences: 6

- [https://diemel.renaturiert.org/](https://diemel.renaturiert.org/) — 27 of 27 images without width/height

#### Large DOM (over 1500 elements) slows rendering & interaction

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

- [https://diemel.renaturiert.org/renaturierung](https://diemel.renaturiert.org/renaturierung) — the page has 2511 DOM elements (recommended maximum is around 1500) — a large DOM increases style-recalculation, layout and paint cost, hurting LCP and INP. Flatten deep nesting, paginate long lists/tables, and lazy-render off-screen elements.

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

- Rule: `perf.images_legacy_format` · Category: Performance · Occurrences: 3

- [https://diemel.renaturiert.org/](https://diemel.renaturiert.org/) — 3 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.
- [https://diemel.renaturiert.org/hinter-dem-projekt](https://diemel.renaturiert.org/hinter-dem-projekt) — 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.
- [https://diemel.renaturiert.org/renaturierung](https://diemel.renaturiert.org/renaturierung) — 14 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.

#### Large HTML document

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

- [https://diemel.renaturiert.org/renaturierung](https://diemel.renaturiert.org/renaturierung) — 2.6 MiB

#### No Last-Modified header (no conditional GET for unchanged pages)

- Rule: `perf.no_last_modified` · Category: Performance · Occurrences: 6

- [https://diemel.renaturiert.org/](https://diemel.renaturiert.org/) — the response carries no Last-Modified header — Googlebot can't send an If-Modified-Since request, so it re-downloads the full page body on every crawl even when nothing changed. Emit Last-Modified (or an ETag) on stable pages to enable 304 Not Modified responses.

#### robots.txt missing (root returns 404/none)

- Rule: `robots.txt_missing` · Category: Robots · Occurrences: 1

- [https://diemel.renaturiert.org/](https://diemel.renaturiert.org/) — robots.txt did not return a 200 at the site root — a healthy site should serve one (declare your sitemap and confirm the host serves root files)

#### target=_blank link without rel=noopener (tab-napping)

- Rule: `security.unsafe_cross_origin_links` · Category: Security · Occurrences: 3

- [https://diemel.renaturiert.org/](https://diemel.renaturiert.org/) — 4 external link(s) use target="_blank" without rel="noopener" — the opened page can hijack your tab (reverse tab-napping). Add rel="noopener noreferrer".

## 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"}
```

`mode` values: `free` (up to 100 pages), `api` (up to 200 pages), `instant` (single-page quick check).
Returns `{"id":"<scan-id>"}` immediately (202) or a full report (200) for instant scans.

**Get the JSON report**

```
GET https://crawlinx.com/api/scan/{id}/report
```

Returns the full structured report JSON once the scan completes.

**Get this Markdown report**

```
GET https://crawlinx.com/r/{id}.md
```

Returns this LLM-ready Markdown document.

**List recent public audits**

```
GET https://crawlinx.com/api/reports
```

### Quick start (curl)

```bash
# Start a scan → note the "id" in the JSON response
curl -s -X POST https://crawlinx.com/api/scan \
  -H 'Content-Type: application/json' \
  -d '{"url":"https://example.com","mode":"free"}'

# Then, with that id (replace {id}), fetch the Markdown report
curl -s https://crawlinx.com/r/{id}.md
```
