Gregius Optimizer gives content editors and site administrators a unified control panel for search, social, and AI metadata — without leaving the block editor.
<h4>Panels</h4>
<ul>
<li>Sitemap — Toggle post types, taxonomies, and authors in your XML sitemap. Exclude individual posts from search engines with a single click.</li>
<li>Robots.txt — Edit your robots.txt file from a modal textarea with dynamic row sizing. Reset to WordPress defaults at any time.</li>
<li>Schema — Full schema.org type map with 176 subtypes across 9 categories (Article, WebPage, CreativeWork, Event, Organization, Person, Place, Product, Review). Assign global defaults per post type, override per post, and preview JSON-LD with clipboard copy. Organization JSON-LD includes sameAs and logo.</li>
<li>Social Cards — Per-platform title, description, and image overrides for Google Search Snippets, Open Graph (Facebook, LinkedIn), and Twitter/X Cards. Inline live previews with character counters (Google 60/160, OG 55/65, Twitter 70/200). Global fallback image with kebab menu.</li>
<li>LLMs — Auto-generate <code>/llms.txt</code> from site content for AI agent discoverability. Custom context editing with live preview. Per-post include toggle with custom descriptions.</li>
</ul>
All panels are accessible from <code>PluginDocumentSettingPanel</code> in the Gutenberg sidebar, listed in order: Sitemap → Robots → Schema → Social Cards → LLMs.
<h4>Key Features</h4>
<ul>
<li>Meta description and canonical URL output via <code>wp_head</code></li>
