<p>Slug-Free Permalinks lets you switch selected post types and taxonomies to simple ID based permalink formats.</p>
<p>You can choose between:</p>
<ul>
<li><code>/post/123/</code></li>
<li><code>/post-123/</code></li>
</ul>
<p>The plugin only affects the post types and taxonomies you enable in the settings screen.</p>
<p>Features:</p>
<ul>
<li>Select individual public post types</li>
<li>Select individual public taxonomies</li>
<li>Choose slash or hyphen based ID permalink format</li>
<li>Optionally redirect legacy slug URLs to the current ID based permalink when WordPress can resolve the request</li>
<li>Preserve prefixed permalink bases such as <code>/en/</code> when another plugin adds them</li>
<li>Flush rewrite rules automatically when settings change</li>
</ul>
<p>This plugin is focused on permalink structure only. It does not add content features or front-end UI.</p>
<p>Plugin page (English): https://happas.jp/en/slug-free-permalinks/<br />
Plugin page (Japanese): https://happas.jp/slug-free-permalinks/</p>
<p>Development repository: https://github.com/1008k/slug-free-permalinks</p>
<p>This plugin is best suited to new sites, sites still defining their permalink policy, or structured-content use cases where slug management is unnecessary.</p>
<p>If your site already has a large number of published posts and established slug based URLs, review the impact carefully before enabling it. Check existing inbound links, search traffic, social shares, and editorial workflow assumptions.</p>
<p>Known limitations:</p>
<ul>
<li>If a post type slug and taxonomy slug are identical, their ID based rewrite patterns can conflict.</li>
</ul>

<p>Greek text turns into a long series of non-readable symbols when appeared in URLs, which makes it look bad. This plugin solves the problem and it just works! This plugin converts Greek characters in post, page and term slugs to Latin characters. (Greeklish). The title of an article in Greek “https://www.problogger.gr/κατασκευή-και-προώθηση-ιστοσελίδων” will be “https://www.problogger.gr/kataskevi-proothisi-istoselidon”.
