NINJA AI SEO
Search is shifting from ten blue links to AI answers. When ChatGPT, Claude, Grok, Perplexity or Gemini crawl your site, a handful of signals decide whether they can read, understand and cite your content. NINJA AI SEO scores those signals and shows you exactly what to fix.
AI visibility (site-level):
- AI crawler access — checks whether your robots.txt lets GPTBot, ClaudeBot, Google-Extended, PerplexityBot and Common Crawl in. Block them and you can never be quoted.
- Structured data — emits schema.org JSON-LD (Article/WebPage) on every post and page, turning your prose into facts a model can extract and trust.
- llms.txt — detects the site-root file that tells LLMs what your best content is (Pro generates it for you).
- XML sitemap — confirms crawlers can discover every page.
On-page audit (per post/page, scored 0–100):
- Meta description — the summary engines read first and often quote
- SEO title length — how your page is titled and attributed
- Image alt text — the only thing a text model “sees” in an image
- Content length, subheadings, internal links
The Overview tab gives you a site SEO-health score, an AI-visibility panel, and your top opportunities. For every page you can set the SEO title and meta description by hand; NINJA AI SEO outputs them (and the JSON-LD) on the front end immediately. The free plugin is fully functional on its own and makes no external connections.
NINJA AI SEO Pro (optional add-on)
NINJA AI SEO Pro is a separate add-on (available from https://ninja.si — not from the WordPress.org directory) that adds a one-click auto-fix engine: it generates meta descriptions and SEO titles from each page’s own content and backfills missing image alt text, per page or across the whole site. Pro is the only part that connects to ninja.si, and only after you choose to activate it.
Privacy
The free plugin sends no data anywhere — all auditing happens locally in your WordPress install. (The optional Pro add-on contacts ninja.si only when you register it; see the Pro readme.)
