What it does

Live-site crawl: BFS crawler, health score, broken links, redirect chains, orphan pages, per-page timing.

Batch document audit: scans your markdown/HTML directory for title collisions, thin content (<300 words), broken canonicals, missing alt text.

Schema.org validator: checks JSON-LD (SoftwareApplication, Article, Organization, Product) against current spec, flags deprecated schemas.

Robots.txt / AI crawler radar: checks what GPTBot, ClaudeBot, PerplexityBot, Google-Extended, and others are actually allowed to see.

Sitemap validator: <loc>, <lastmod>, HTTPS enforcement, the 50k URL limit, hreflang.

SERP + keyword research: scrapes DuckDuckGo's HTML and suggest endpoints directly. No paid API key.

GEO scoring: citation-likelihood scoring for AI answer engines, via TypeSafe's Jev model (a typed-decision model, not a chat LLM), needs a free API key for this part only.

MCP server: jev-seo mcp exposes 10 tools over stdio JSON-RPC for Claude Code, Gemini CLI, and other agent clients.

Quick start

Everything below runs with no API key except the GEO scoring, which needs a free TYPESAFE_API_KEY.

\`bash
cargo install jev-seo

export TYPESAFE_API_KEY=your_key_here

jev-seo crawl https://example.com --max-pages 10

Why jev-seo?

Semrush and Ahrefs cost upwards of $130 per month. OpenSEO still requires paid DataForSEO credit cards. Most SEO suites are bloated web dashboards filled with vanity charts.

Zero subscriptions (₹0): Scrapes DuckDuckGo HTML and suggest endpoints directly. No credit cards, no paid API keys.

Numbers

Measured 2026-09-22, full notes in the repo's docs/EVAL.md.

Check	Result
Cold start	6ms
Local audit, 4 files	~0.2s
Live crawl, 6-10 pages	3-11s, server-bound
Score repeatability, 3 runs	99 stable

Everything deterministic (crawl, audit, schema, robots, sitemap) runs with zero API keys. Only the Jev-backed semantic scoring needs a key, and that's fractions of a cent per call.
