Descripción
Hydori is the SEO + AI translation platform built for WordPress. Connect your site, choose your target languages, and Hydori translates your posts and pages into 20+ languages; then publishes them directly to WordPress as SEO-ready posts with hreflang tags, translated meta titles and descriptions, and proper source-translation relationships.
This plugin is the bridge between your WordPress site and the Hydori platform. It handles content export, translation delivery, SEO metadata sync, multilingual plugin wiring, and a live SEO and AI-readiness scoring panel inside the Gutenberg block editor.
The Problem Hydori Solves
Going multilingual on WordPress involves a lot more than translating text. You need hreflang tags set correctly so Google serves the right language to the right audience. You need translated meta titles and descriptions in your SEO plugin. You need multilingual plugins to recognise the posts as a translation group. You need slugs localised, categories mapped, featured images carried across, and brand terms left untranslated.
Most translation solutions stop at generating text and leave the rest to you. Hydori handles the full chain – from AI translation through to a properly published, SEO-configured WordPress post in every target language.
How Hydori Works
- Install and connect – Activate this plugin, visit Hydori & link your site.
- Choose your languages – Select target languages and a translation style (Professional, Casual, or Technical). Existing posts are indexed in Hydori automatically.
- Translate – Click Translate on any article, or bulk-translate your entire site in one action. Hydori’s AI handles the content while respecting your Brand Glossary terms.
- Publish – Translated posts are pushed to WordPress automatically as drafts or live posts, with SEO metadata, hreflang tags, featured images, categories, and multilingual plugin relationships all set.
- Track – Monitor translation status across every post and language from the Hydori dashboard: Done, Pending, Failed, or awaiting review.
Key Platform Features
- AI Translation in 20+ Languages – Accurate, context-aware translations powered by AI, not word-for-word substitution
- Translation Style Control – Choose Professional, Casual, or Technical tone per site
- Brand Glossary – Define terms that must never be translated (product names, brand names, proper nouns)
- Bulk Translation – Translate your entire site’s content in one action
- Translation Status Dashboard – See every post’s status per language: Done, Pending, Failed, or Missing
- Auto-Translate New Posts – Newly published WordPress posts are picked up and translated automatically
- Require Review Mode – Translations arrive as drafts so your team can review before they go live
- Team Collaboration – Invite team members with Admin, Editor, or Viewer roles
WordPress Integration Features
- SEO Metadata Sync – Translated meta titles, descriptions, focus keywords, Open Graph tags, Twitter Card tags, and canonical URLs are written directly to Yoast SEO, Rank Math, All in One SEO, or SEOPress – whichever is active
- Multilingual Plugin Integration – Translation relationships are created automatically as Source-Translation pairs along with an easy to digest admin panel view
- hreflang Fallback – If no multilingual plugin is active, Hydori emits native
rel="alternate"hreflang tags in<head>so Google still understands your language structure - Live SEO & GEO Scoring Sidebar – A panel in the Gutenberg block editor shows your SEO score (0-100) and AI-readiness grade (A-F) with per-check breakdowns and an editable focus-keyword field, fetched from Hydori and cached locally
- Score Columns in Posts and Pages List – SEO and GEO scores appear as colour-coded, sortable columns across your entire content library (green ≥80, amber 60-79, red <60)
- Language Switcher Block – A native Gutenberg block that renders translation links on single posts and available languages on archive pages, with dropdown, list, inline, and button display styles
- Featured Image Sync – Images are downloaded and attached as post thumbnails on each translated post
- Category and Tag Mapping – Categories and tags are created and assigned automatically during publishing
- Auto-Export on First Connect – Existing published posts are indexed in Hydori in the background the moment you connect, with no manual action needed
- Secure API Key – Auto-generated on activation and stored securely in your WordPress database

Why Choose Hydori Over Other Translation Solutions?
Generic AI translation tools give you text. They do not set hreflang tags, do not write translated meta descriptions into Yoast, do not create source-translation groups, and do not preserve your brand terminology. You end up doing all the SEO configuration by hand, in every language, for every post.
Hydori handles the complete multilingual publishing chain. Translation, SEO metadata, hreflang tags, multilingual plugin relationships, featured images, categories, and tags – all delivered to WordPress in a single sync. And unlike per-word translation services, Hydori uses a credits-based lifetime deal so the cost does not grow with your content volume.

Preguntas frecuentes
-
What is Hydori?
-
Hydori is an autonomous SEO platform that detects ranking issues, generates AI-powered content fixes, publishes them directly to your WordPress site, and proves which actions moved rankings. It handles the full SEO operations loop so you can focus on strategy instead of manual work.
-
How is Hydori different from Rank Math or Yoast?
-
Rank Math and Yoast are on-page SEO plugins that help you optimize individual posts inside WordPress. Hydori is a full SEO operations platform that works alongside them – it detects ranking drops across your entire site, generates AI content fixes, publishes updates directly to WordPress (with Yoast/Rank Math metadata filled automatically), and proves which fixes improved rankings. They complement each other.
-
Can Hydori detect content decay and declining rankings automatically?
-
Yes. Hydori connects to your Google Search Console and scans for six types of issues every day: declining pages, low-hanging fruit opportunities, content cannibalization, content decay, missing topics, and AI search optimization gaps. Detection is fully automatic – no manual audits or spreadsheets required.
-
Does Hydori work with Google Search Console and Google Analytics?
-
Hydori requires Google Search Console for its core detection engine. Google Analytics (GA4) integration is available on Scale and Command plans for linking rankings to traffic and conversion data.
-
Can I use my own OpenAI or Anthropic API key with Hydori?
-
Yes. Hydori supports BYOK (Bring Your Own Key) on all plans. Connect your own OpenAI or Anthropic API key and run unlimited AI operations at the provider’s cost instead of using Hydori credits.
-
How does Hydori prove that SEO fixes actually worked?
-
The Agentic Impact Scorecard tracks every fix and links it to specific ranking changes. It separates the effect of your actions from algorithm updates, seasonality, and competitor changes – so you can show exactly what worked. For example: “Content refresh on /blog/guide: +8 positions in 12 days.”
-
Can agencies use Hydori for multiple client WordPress sites?
-
Yes. The Scale plan supports 5 sites and the Command plan supports unlimited sites from a single dashboard. Command also includes white-label branded reports and client portals.
-
Does this plugin work on WooCommerce-powered sites?
-
Yes. If your site uses WooCommerce, Hydori can publish blog posts and pages to your WordPress site. The plugin currently supports the
postandpagepost types. WooCommerce product descriptions (theproductpost type) are not supported at this time. -
Do I need a Hydori account?
-
Yes, you need an active Hydori account to use the platform features. The WordPress plugin is free and handles the connection between your site and Hydori. Sign up at hydori.io.
-
Is the WordPress plugin free?
-
Yes, the WordPress plugin is completely free. Hydori platform access is based on your subscription plan, starting at $79/month with a $5 trial available.
-
Which SEO plugins does Hydori work with?
-
Hydori automatically syncs SEO metadata with Yoast SEO, Rank Math, All in One SEO Pack, and SEOPress. Meta titles, descriptions, and focus keywords are set during content publishing.
-
Which multilingual plugins are supported?
-
We support WPML, Polylang, and TranslatePress. Translation relationships are automatically created when you publish translated content, including proper hreflang tag configuration.
-
Can I edit content after Hydori publishes it?
-
Yes. Content publishes as drafts by default, giving you full editorial control. You can review, edit, and publish using your familiar WordPress editor.
-
What happened to my API key?
-
The API key is automatically generated when you activate the plugin and stored securely in your WordPress database. If it is missing, click “Regenerate API Key” in the settings page.
-
This usually means the API key in Hydori does not match your WordPress key. Go to Settings > Hydori, copy the current API key, update it in your Hydori dashboard, and click “Test Connection” to verify.
-
How do I troubleshoot connection issues?
-
- Enable “Debug Mode” in Settings > Hydori
- Click “Test Connection” to see detailed results
- Check your WordPress debug.log file for entries starting with “Hydori”
- Contact support at hydori.io/contact if issues persist
-
Is my data secure?

Registro de cambios
2.9.0
- New: SEO & GEO scoring panel in the block editor sidebar. Displays live SEO (0–100) and GEO/AI readiness (A–F) scores with collapsible check categories, a circular progress ring, and an editable focus keyword field. Scores are fetched from the Hydori backend and cached in post meta for instant display on re-open. Compatible with Yoast and Rank Math focus keywords.
- New: SEO and GEO score columns in the Posts/Pages admin list. Scores are color-coded (green ≥80, amber 60–79, red <60) and sortable, giving you a site-wide content health snapshot at a glance.
- New: Bulk-scores REST endpoint (POST /wp-json/hydori/v1/bulk-scores) lets the Hydori backend push cached SEO/GEO scores for multiple posts in a single server-to-server call after import.
- New: Posts list REST endpoint (GET /wp-json/hydori/v1/posts) returns paginated published posts with full Hydori metadata, enabling the backend to fetch and index your content without relying on the standard WP REST API.
- New: Onboarding bulk export. When Hydori credentials are saved for the first time the plugin automatically schedules a background export of all existing published posts so your content is indexed immediately without any manual action.
- Improved: Site languages are now fetched live from the Hydori API (1-hour cache) so the language list stays accurate as you add or remove languages in the dashboard. Falls back to the last-known list when the API is unreachable.
2.8.0
- New: Language Switcher Gutenberg block. Adds a native WordPress block that renders translation links on single posts and available site languages on archive/index pages, with dropdown, list, inline, and buttons display styles.
- Improved: Posts/Pages admin list now groups translation rows under their source post, with an expand/collapse toggle, so multilingual content is easier to manage at a glance.
- Improved: Admin settings page restructured — Help & Support section added, Diagnostics moved below Advanced settings.
2.7.0
- New: Multilingual support. Hydori now manages language-prefixed URLs and hreflang tags for translated posts. Enabled by default on all installs (new and upgraded).
- New: “Add translation” button in the WordPress editor lets you create a translated post for any source post without syncing to Hydori first.
- New: Language and Type columns in the WordPress Posts/Pages admin list show each post’s language and whether it is a source or translation, with links to related posts.
- New: Admin language filter dropdown above the Posts/Pages table for quick filtering by language.
- New: _hydori_wp_source_post_id postmeta key tracks the WP-native source post ID for translations created before a Hydori sync.
- Improved: Import from WordPress modal now fetches draft posts (including WP-native translations) when WordPress application passwords are configured.
- Improved: Source/Translation Type column links correctly resolve for posts created and translated entirely within WordPress, without requiring a Hydori sync first.
2.6.0
- New: Translation loop prevention. Posts created by Hydori (translations pushed back to WordPress) are now marked with the _hydori_managed postmeta flag and are skipped by the auto-export hook. This eliminates the rare but catastrophic feedback loop where a translated post could be re-pushed to Hydori, re-translated, and republished, multiplying content exponentially.
- New: Hydori postmeta keys (_hydori_managed, _hydori_source_article_id, _hydori_translation_language, hydori_article_id, hydori_language, hydori_translation_of) are now exposed via the WordPress REST API so the Hydori backend can dedupe inbound posts and prevent the same loop on legacy plugin versions.
- Internal: Layered defense documented inline in class-hydori-export-manager.php so future contributors do not silently regress the guard.
2.5.0
- Streamlined settings UI focused on connection status. Removed redundant import, featured-images, and export controls now handled inside the Hydori dashboard.
2.4.0
- New: Automatic sync mode is now the default for both new installs and upgraded sites (sites that never explicitly chose manual). Publish once in WordPress, Hydori translates and republishes as live posts. Existing users who explicitly picked “manual” keep their choice.
- New: Translated posts now carry the full SEO metadata set. Open Graph title/description, Twitter Card title/description, canonical URL, focus keyword, featured-image alt text, and per-post robots flags are written to Yoast, Rank Math, All in One SEO, and SEOPress in every supported language.
- New: hreflang fallback. When no multilingual plugin (WPML, Polylang, TranslatePress) is active, Hydori emits rel=”alternate” hreflang tags in linking every translated version of a post, plus an x-default fallback.
- New: Self-referencing canonical URL on translated posts when no SEO plugin is active.
- New: REST endpoint POST /wp-json/hydori/v1/settings so the Hydori dashboard can flip sync mode and default post status remotely.
- New: Featured image alt text is now translated per language on the attachment (via _wp_attachment_image_alt).
- Note: Upgrading from 2.3.x flips inherited “manual + draft” defaults to “auto + publish” only on sites that never toggled the setting themselves. Explicit choices are preserved.

- Updated: Admin settings section renamed from “Settings” to “Import Settings” for clarity
