Description

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.)

Installation

In your WordPress admin go to Plugins Add New, search for “NINJA AI SEO” and click Install Now — or upload the plugin ZIP under Plugins Add New Upload Plugin.
Click Activate.
Open NINJA AI SEO in the admin menu. The Overview tab shows your site SEO-health score and AI-visibility signals; the Audit tab scores every post and page; the AI Crawlers tab lets you allow or block individual AI bots.
On any post or page, set the SEO title and meta description from the Audit tab — NINJA AI SEO outputs them, and the schema.org JSON-LD, on the front end immediately.

No account, API key or external service is required.

FAQ

Does the free plugin phone home?: No. It makes no external requests. Everything runs inside your install.
Will it conflict with another SEO plugin?: NINJA AI SEO outputs a meta description and title only when you set them. If another
SEO plugin already manages those, run one or the other to avoid duplicate tags.
