element (or role=main) around the primary content #### Page served uncached (no-store/private or CDN bypass) - Rule: `cache.not_cacheable` · Category: Cache · Occurrences: 1 - [https://vnexpress.net/](https://vnexpress.net/) — Cache-Control: max-age=60, stale-while-revalidate=6, stale-if-error=864000, private #### Low text-to-HTML ratio - Rule: `content.low_ratio` · Category: Content · Occurrences: 1 - [https://vnexpress.net/](https://vnexpress.net/) — 3.6% #### robots.txt blocks AI search/citation crawlers - Rule: `geo.ai_bots_blocked` · Category: Geo · Occurrences: 1 - [https://vnexpress.net/](https://vnexpress.net/) — robots.txt disallows AI search crawler(s): oai-searchbot (ChatGPT search), perplexitybot (Perplexity), claude-searchbot (Claude (search)). These fetch pages to cite in AI answers, so blocking them removes you from that citation pool. Allowing them is required for AI citations (though not a guarantee of them); blocking training bots like GPTBot/ClaudeBot is a separate, valid choice. #### Likely hero image lacks fetchpriority=high - Rule: `images.hero_no_fetchpriority` · Category: Performance · Occurrences: 1 - [https://vnexpress.net/](https://vnexpress.net/) — the likely hero/LCP image (logo_tagline.svg) 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. #### Images without width/height (layout shift / CLS) - Rule: `images.missing_dimensions` · Category: Images · Occurrences: 1 - [https://vnexpress.net/](https://vnexpress.net/) — 33 of 33 images without width/height #### Internal link has no anchor text / accessible name - Rule: `links.no_anchor_text` · Category: Links · Occurrences: 1 - [https://vnexpress.net/](https://vnexpress.net/) — 35 internal link(s) have no anchor text, aria-label, or image alt — they pass no keyword signal and are unusable to screen readers. Add descriptive text or an aria-label. #### Legacy tag present (Google ignores it) - Rule: `meta.keywords_present` · Category: Content · Occurrences: 1 - [https://vnexpress.net/](https://vnexpress.net/) — a tag is present — Google has ignored it since 2009; remove it to cut template debt #### Meta description too long - Rule: `meta_desc.too_long` · Category: Meta Description · Occurrences: 1 - [https://vnexpress.net/](https://vnexpress.net/) — 192 chars #### Legacy image format (jpg/png/gif) with no next-gen fallback - Rule: `perf.images_legacy_format` · Category: Performance · Occurrences: 1 - [https://vnexpress.net/](https://vnexpress.net/) — 5 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 Last-Modified header (no conditional GET for unchanged pages) - Rule: `perf.no_last_modified` · Category: Performance · Occurrences: 1 - [https://vnexpress.net/](https://vnexpress.net/) — 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. #### Slow server response - Rule: `perf.slow_response` · Category: Performance · Occurrences: 1 - [https://vnexpress.net/](https://vnexpress.net/) — 4886 ms #### Deprecated schema type with no Google rich result - Rule: `schema.deprecated_type` · Category: Structured Data · Occurrences: 1 - [https://vnexpress.net/](https://vnexpress.net/) — deprecated rich-result type(s) present: Sitelinks Searchbox. The markup is valid schema.org but Google no longer generates a rich result for it — remove or repurpose the block. ## Checks & coverage Crawlinx ran **157 technical-SEO checks** across 27 categories.

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
