Each WordPress verdict uses the same rankd quota as the web product: free accounts get 2 verdicts per day; Pro gets 500 verdicts per month. What it does Editor sidebar verdict — opens as a meta box on every post and page edit screen Six axes scored 0-100 — readability, structure, length, links, images, title Actionable suggestions — short, specific, ranked by impact Quota-aware — runs only when you click, so typing does not burn verdicts Works in Gutenberg and Classic Editor — auto-detects which one you are using External Services This plugin connects to https://rankd.voiddo.com/api/wp/content-score when you click run rankd verdict.

The basics that lift any post regardless of niche. Six axes scored Readability — sentence length and word complexity (lower is easier) Structure — H2/H3 distribution and section count Length — sweet-spot around 800-2000 words; penalty at the extremes Links — outbound + internal density (1 per ~250 words is healthy) Images — at least one image with alt text on posts over ~200 words Title — 30-65 characters is the SEO sweet spot The composite is a weighted average; each axis is exposed individually so you can see what is dragging. How it differs from generic readability tools Lives where you write — the WordPress editor sidebar — not a separate site Uses the same rankd quota and upgrade path as the main product Runs on explicit click only — no quota burn while typing Keeps the verdict separate from publishing — you decide what to change About Built by vøiddo — a small studio shipping AI-flavoured products, free dev tools, Chrome extensions and weird browser games.

The SEMrush SEO Writing Assistant plugin read only from post title and post content elements for the real time check. This lightweight plugin allows you to use an arbitrary value for that check in addition to those values. So, if you are using some kind of a page builders, field managers and so on, you have only to define a constant in your wp_config.php file and eventually to write a little bit of JavaScript code in order to specify which fields. Note that the plugin don’t replace SEMrush SEO Writing Assistant but is intended to be used together. Usage Once the plugin is activated you can configure it by defining following constants in your wp-config.php: SWA_SEMRUSH_CUSTOM_FIELDS_PLUGIN_AUTOENABLE Automatically enable use of additional text value for SEMrush check. The default value is false. This is the only configuration you have to do in order to have the plugin feature working. For example: define( 'SWA_SEMRUSH_CUSTOM_FIELDS_PLUGIN_AUTOENABLE', true ); SWA_SEMRUSH_CUSTOM_FIELDS_PLUGIN_INTERVAL Allows to change the interval between automatic updates of the text used by SEMrush checks. The default value is 5 seconds.For example: define( 'SWA_SEMRUSH_CUSTOM_FIELDS_PLUGIN_INTERVAL', 10 ); You can alernatavely control the plugins programmatically, by using semrush_seo_writing_assistant_post_types (optional) filter and SeoWritingAssistantSEMrushCustomFields JavaScript object (see below). API WordPress Hooks **swa_semrush_custom_fields_settings ** Filters plugin settings values. apply_filters( 'swa_semrush_custom_fields_settings', array $settings ) semrush_seo_writing_assistant_post_types Filters post types where to enable plugin. Default to array( 'post', 'page', 'product' ). apply_filters( 'semrush_seo_writing_assistant_post_types', array $post_types ) The filter has the same name as the one used by SEMrush SEO Writing Assistant plugin (since version 1.0.4) used for the same purpose. JavaScript Event seo-writing-assistant-semrush This event allows you to update the text for SEMrush analysis. The following example will update text for SEMrush check every 5 seconds, using excerpt and my_custom_fields custom field values (working both with block and classic editors): jQuery( document ).ready( function() { var swa = new SeoWritingAssistantSEMrushCustomFields( { interval: 5 } ); jQuery( document ).on( 'seo-writing-assistant-semrush', function( event, data ) { data.html += jQuery( '#excerpt' ).val() + "\n" + jQuery( '.editor-post-excerpt__textarea textarea').val() + "\n" + jQuery( '#my_custom_fields' ).val(); } ) } ); Note that if you have previously defined constant SWA_SEMRUSH_CUSTOM_FIELDS_PLUGIN_AUTOENABLE to true, you don’t have to create new SeoWritingAssistantSEMrushCustomFields object. JavaScript API setHtml() The following example will update programmatically the text used by SEMrush check with an arbitrary value: jQuery( document ).ready( function() { var swa = new SeoWritingAssistantSEMrushCustomFields( { interval: 0 } ); swa.setHtml( 'foo baz bar' ); } ); Advanced Custom Fields The plugin checks if Advanced Custom Fields is active in your WordPress instance and adds a custom setting to each field (only for input within text, radio and checkbox type, textarea and select elements) allowing you to add his value to SEMrush check without having to write any additional JavaScript code. Autodiscovery The plugin also automatically add to text used by SEMrush checks, the values of all HTML elements with swa-scf class or data-swa-scf attribute. This will applied only for input (within text, radio and checkbox type), textarea, and select elements.
