Pick one canonical host/scheme and 301-redirect the others. ### Notices (24) #### No llms.txt for AI agents - Rule: `agent.llms_txt_missing` · Category: Agent Readiness · Occurrences: 1 - [https://ctfoto.org/](https://ctfoto.org/) — no llms.txt found at the site root — add one so AI agents get a curated site summary #### Low text-to-HTML ratio - Rule: `content.low_ratio` · Category: Content · Occurrences: 4 - [https://ctfoto.org/](https://ctfoto.org/) — 2.3% - [https://ctfoto.org/contact](https://ctfoto.org/contact) — 3.1% - [https://ctfoto.org/guestbook](https://ctfoto.org/guestbook) — 1.9% - [https://ctfoto.org/portfolio](https://ctfoto.org/portfolio) — 0.7% #### Image filename is generic/auto-generated (missed image-search signal) - Rule: `images.generic_filename` · Category: Images · Occurrences: 2 - [https://ctfoto.org/](https://ctfoto.org/) — 4 image(s) use a generic/auto-generated filename (e.g. IMG_1234.jpg, photo1.png, a bare UUID). Google reads the filename as a signal of image content, so rename files descriptively (hyphen-separated words) before upload. - [https://ctfoto.org/portfolio](https://ctfoto.org/portfolio) — 36 image(s) use a generic/auto-generated filename (e.g. IMG_1234.jpg, photo1.png, a bare UUID). Google reads the filename as a signal of image content, so rename files descriptively (hyphen-separated words) before upload. #### Likely hero image lacks fetchpriority=high - Rule: `images.hero_no_fetchpriority` · Category: Performance · Occurrences: 1 - [https://ctfoto.org/](https://ctfoto.org/) — the likely hero/LCP image (dsc02252.jpg) has no fetchpriority="high" — adding it tells the browser to fetch the hero earlier in the waterfall, reducing Largest Contentful Paint. This is a low-severity nudge; verify the flagged image is actually your LCP element. #### Legacy image format (jpg/png/gif) with no next-gen fallback - Rule: `perf.images_legacy_format` · Category: Performance · Occurrences: 2 - [https://ctfoto.org/](https://ctfoto.org/) — 6 image(s) use a legacy format (jpg/png/gif) with no next-gen fallback.

Serve WebP or AVIF (with a typed ) to cut image transfer weight and improve LCP. #### No ETag header (no conditional GET for unchanged pages) - Rule: `perf.no_etag` · Category: Performance · Occurrences: 4 - [https://ctfoto.org/](https://ctfoto.org/) — 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.

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":""}` 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 ``` Full API reference & usage rules: https://crawlinx.com/api
