<p><strong>Hreflang Customizer</strong> is a free plugin that generates hreflang tags for your WordPress pages automatically. It works on any site — no multilingual plugin is required.</p>
<p>Hreflang tags tell search engines which language and region each page targets. This prevents duplicate-content issues across multilingual or multi-regional sites and helps the right version of your page rank in the right country.</p>
<h4>Key Features</h4>
<ul>
<li>✅ Works <strong>without</strong> any translation plugin — standalone mode out of the box</li>
<li>✅ Also integrates with <strong>Weglot</strong> for translated URL mapping</li>
<li>✅ Searchable language picker with 180+ languages and regional variants</li>
<li>✅ Selected languages shown as removable tag chips with language codes</li>
<li>✅ Language list cached via WordPress Transients API (no repeated API calls)</li>
<li>✅ Clean, modern admin UI — fully responsive</li>
<li>✅ No upsells, no premium tier — 100% free</li>
</ul>
<h4>How It Works</h4>
<p><strong>Standalone mode:</strong> Select your target language codes in the settings page. The plugin outputs one <code><link rel="alternate" hreflang="..."></code> tag per selected code in the <code><head></code> of every page, pointing to the canonical URL of that page.</p>
<p><strong>Weglot mode:</strong> If Weglot is installed and active, the plugin maps Weglot’s translated URLs to your selected hreflang codes automatically.</p>
<h4>Example Output</h4>
<pre><code><link rel="alternate" href="https://yoursite.com/about/" hreflang="en-AU" />
<link rel="alternate" href="https://yoursite.com/about/" hreflang="en-GB" />
<link rel="alternate" href="https://yoursite.com/" hreflang="x-default" />
</code></pre>
<h4>Third-Party Service</h4>
<p>This plugin optionally fetches an extended language list from <strong>https://app.seo-hreflang.com/api/languages</strong> to supplement its built-in language database. The request is made at most once every 12 hours. No personal data, user data, or site content is transmitted — the request contains no body payload. The result is cached locally using the WordPress Transients API.</p>
<p>If the external service is unavailable, the plugin automatically falls back to its built-in list of 180+ languages and continues to work normally.</p>
