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):
<ul>
<li>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.</li>
<li>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.</li>
<li>llms.txt — detects the site-root file that tells LLMs what your best 
content is (Pro generates it for you).</li>
<li>XML sitemap — confirms crawlers can discover every page.</li>
</ul>
On-page audit (per post/page, scored 0–100):
<ul>
<li>Meta description — the summary engines read first and often quote</li>
<li>SEO title length — how your page is titled and attributed</li>
<li>Image alt text — the only thing a text model “sees” in an image</li>
<li>Content length, subheadings, internal links</li>
</ul>
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.
<h3>NINJA AI SEO Pro (optional add-on)</h3>
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.
<h3>Privacy</h3>
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.)

VS Meta Description

it's really foolish to stick a single meta description in the sitewide header template. that's duplicate content so google knows immediately it's poor quality. it will do more harm than good to your rankings.

1 description duplicated sitewide = bad seo

Simple plugin doing exactly what it is supposed to without bloat. 
Maybe a button could be added to the Default Open Graph Image field, to select the image directly from the library instead of pasting its URL.

Works perfectly

The plugin works perfectly, it is extremely small (8kb zipped), which is a big plus, and the developer is super nice, very responsive and simply awesome.

Thanks a million,
Nick.

A 5 star plugin

Its perfect

With this lightweight plugin you can add a meta description to your website.
