<h3>External Services</h3>
<p>This plugin connects to the following external services:</p>
<h4>RationalWP Plugin Directory</h4>
<p>This plugin fetches a list of available RationalWP plugins from <a href="https://rationalwp.com/" rel="nofollow ugc">rationalwp.com</a> to display in the WordPress admin menu. Only the menu file version number is sent as a cache-busting query parameter. No user data is transmitted. The response is cached locally for 24 hours.</p>
<ul>
<li>Service URL: <a href="https://rationalwp.com/plugins.json" rel="nofollow ugc">https://rationalwp.com/plugins.json</a></li>

<li>Privacy Policy: <a href="https://rationalwp.com/privacy/" rel="nofollow ugc">https://rationalwp.com/privacy/</a></li>
</ul>
<h4>OpenAI API (optional)</h4>
<p>This plugin provides optional AI-powered SEO suggestions using the <a href="https://openai.com/" rel="nofollow ugc">OpenAI API</a>. When a site administrator configures an OpenAI API key in Settings > Rational SEO > General, users can click “Suggest” or “Generate” buttons in the post editor to receive AI-generated focus keywords, SEO titles, and meta descriptions.</p>
<p>Data is only sent when a user explicitly clicks an AI suggestion button. The data sent includes the post title and up to 2000 characters of post content (stripped of HTML), along with the user’s own API key for authentication. No data is sent automatically or in the background.</p>

</ul>
<h3>Hooks for developers</h3>
<p>RationalSEO exposes a complete set of filters and actions so themes and plugins can customize or extend output without forking the plugin. All hooks were introduced in version 1.0.6.</p>
<h4>Short-circuit filters</h4>
<p><strong>Return non-null to short-circuit default resolution; return null to fall through to internal logic.</strong></p>
<p>These filters let you override the data that RationalSEO resolves internally. Return a non-null value to bypass the built-in logic entirely, or return null to let RationalSEO proceed as normal.</p>
<ul>
<li><code>rationalseo_og_image_data</code> — Return a (partial) image data array; missing keys are filled with safe defaults. Signature: <code>($pre, $context)</code>.</li>
<li><code>rationalseo_meta_description</code> — Return a string to override the meta description. An empty string <code>''</code> means “explicitly no description” and suppresses the tag. Signature: <code>($pre, $context)</code>.</li>
<li><code>rationalseo_post_seo_meta</code> — Return an array of post SEO meta to override the database lookup. Signature: <code>($pre, $post_id)</code>.</li>
<li><code>rationalseo_term_seo_meta</code> — Return an array of term SEO meta to override the database lookup. Signature: <code>($pre, $term_id)</code>.</li>
</ul>
<h4>Per-value filters</h4>
<p>These filters run on the resolved value just before it is output. All use the signature <code>($value, $context)</code>.</p>
<ul>
<li><code>rationalseo_document_title</code> — string. The <code><title></code> tag value before output.</li>
<li><code>rationalseo_canonical_url</code> — string. The <code>rel=canonical</code> URL before output.</li>
<li><code>rationalseo_robots</code> — array. The robots directives array (joined with <code>,</code> for output).</li>
<li><code>rationalseo_og_locale</code> — string. <code>og:locale</code> value before output.</li>
<li><code>rationalseo_og_type</code> — string. <code>og:type</code> value (e.g. <code>website</code> / <code>article</code>) before output.</li>
<li><code>rationalseo_og_title</code> — string. <code>og:title</code> value before output.</li>
<li><code>rationalseo_og_description</code> — string. <code>og:description</code> value before output.</li>
<li><code>rationalseo_og_url</code> — string. <code>og:url</code> value before output.</li>
<li><code>rationalseo_og_site_name</code> — string. <code>og:site_name</code> value before output.</li>
<li><code>rationalseo_twitter_card_type</code> — string. <code>twitter:card</code> value before output.</li>
<li><code>rationalseo_twitter_title</code> — string. <code>twitter:title</code> value before output.</li>
<li><code>rationalseo_twitter_description</code> — string. <code>twitter:description</code> value before output.</li>
</ul>
<h4>Skip filters</h4>
<p>Return a truthy value to suppress an entire output block. Signature: <code>($skip, $context)</code>.</p>
<ul>
<li><code>rationalseo_skip_meta_description</code> — Skip the meta description tag entirely.</li>
<li><code>rationalseo_skip_canonical</code> — Skip the canonical link tag entirely.</li>
<li><code>rationalseo_skip_open_graph</code> — Skip all Open Graph tags entirely.</li>
<li><code>rationalseo_skip_twitter_cards</code> — Skip all Twitter Card tags entirely.</li>
</ul>
<p>Example — disable Open Graph on the entire site:</p>
<pre><code>add_filter( 'rationalseo_skip_open_graph', '__return_true' );
</code></pre>
<h4>Action injection points</h4>
<p>These actions fire immediately before and after each social meta block is emitted. They fire only when the block is not skipped via the corresponding skip filter. Signature: <code>do_action( '...', $context )</code>.</p>
<ul>
<li><code>rationalseo_before_open_graph</code> — Fires before the Open Graph tags are output.</li>
<li><code>rationalseo_after_open_graph</code> — Fires after the Open Graph tags are output.</li>
<li><code>rationalseo_before_twitter_cards</code> — Fires before the Twitter Card tags are output.</li>
<li><code>rationalseo_after_twitter_cards</code> — Fires after the Twitter Card tags are output.</li>
</ul>
<p>Example — append a custom og:* tag after the standard Open Graph block:</p>
<pre><code>add_action( 'rationalseo_after_open_graph', function( $ctx ) {
    // Append extra og:* tags here.
    echo "<meta property=\"og:custom\" content=\"value\" />\n";
} );
</code></pre>
<h4>The $context array</h4>
<p>All per-value filters, skip filters, and action hooks receive a <code>$context</code> array as their last argument. It is built by the internal <code>build_context()</code> method and always contains the following keys:</p>
<ul>
<li><code>mode</code> — string. One of: <code>front_page</code>, <code>home</code>, <code>singular</code>, <code>archive_term</code>, <code>archive_post_type</code>, <code>archive_author</code>, <code>archive_date</code>, <code>search</code>, <code>404</code>, <code>fallback</code>.</li>
<li><code>queried_object</code> — mixed. Result of <code>get_queried_object()</code> at resolution time. May be <code>WP_Post</code>, <code>WP_Term</code>, <code>WP_Post_Type</code>, <code>WP_User</code>, or <code>null</code>.</li>
<li><code>post_id</code> — int. Queried post ID when on a singular view; <code>0</code> otherwise.</li>
<li><code>term_id</code> — int. Queried term ID when on a taxonomy archive; <code>0</code> otherwise.</li>
</ul>
<h4>Worked example</h4>
<p>Override <code>og:type</code> to <code>event</code> for a custom post type, leaving all other post types unchanged:</p>
<pre><code>add_filter( 'rationalseo_og_type', function( $type, $context ) {
    if ( 'singular' === $context['mode'] && 'tribe_events' === get_post_type( $context['post_id'] ) ) {
        return 'event';
    }
    return $type;
}, 10, 2 );
</code></pre>
<p>(<code>tribe_events</code> is illustrative — works for any CPT slug.)</p>
