<p>Greek URL Guard helps Greek WordPress sites create clean Greeklish URLs and upload filenames from the start, without rewriting existing URLs.</p>
<p>It is built for site owners who want safer, readable, SEO-friendly slugs for new content while avoiding unexpected changes to old posts, terms, media files, or indexed URLs.</p>
<p>The plugin converts Greek characters in new posts, pages, public custom post types, categories, tags, public taxonomies, WooCommerce products, WooCommerce product categories, product tags, product attributes, and new media upload filenames. It also includes a slug preview tool and a lightweight SEO safety check for existing Greek slugs, media filenames, and possible overlapping custom slug code.</p>
