By consolidating several essential tools into one cohesive admin interface, this plugin helps you maintain a clean codebase and optimize server resources. This plugin incorporates the following major components: 1. SEO & Optimization Advanced RSS Control: Disable non-essential RSS feeds (returning HTTP 410) to reduce crawler load. Only keeps homepage, category, and author feeds active. HTML Head Cleanup: Removes redundant feed links, RSD, WLManifest, shortlink, and REST API header markings. Robots Meta Customization: Automatically tags tags archive, date archive, internal search, and deep pagination (page 3+) as `noindex, follow` to focus search authority. Sitemap Sanitization: Excludes `post_tag` from WordPress native sitemaps to prevent indexing low-quality archive pages. XML-RPC Hardening: Optionally strips all WordPress XML-RPC methods (wp.*, metaWeblog.*, blogger.*, mt.*, pingback.*), keeping only three harmless system methods, to shut down xmlrpc.php brute-force and pingback abuse without touching .htaccess. Also removes the X-Pingback response header. 2. Comments Control Disable Comments Everywhere: Completely turn off comments, trackbacks, and pingbacks across all post types. Hides historical comments and removes comment menus and widgets from the WordPress dashboard. 3. Media & Thumbnail Optimization Selective Thumbnail Disabling: Stop WordPress from generating specific sizes on upload to save storage space. AJAX Thumbnail Cleanup: A safe, batch-based AJAX cleanup tool (50 attachments per run) to recursively delete historical thumbnail files with a live progress bar. 4. Slug Translator Auto Asian Title to English Slug: Integrates with Google Cloud Translation API to translate Asian-language titles (Chinese, Japanese, Korean, Thai) into clean, lowercase English URL slugs, preventing duplicate URLs and character overflow. The source language is auto-detected. This module shares its core logic with the standalone plugin Chinese to English Slug Converter (zh-to-en-slug): https:// github.com/ivanusto/zh-to-en-slug — use the standalone plugin if slug translation is the only feature you need. 5. Meta Pixel Tracking Meta (Facebook) Pixel integration with PageView, ViewContent, and Search event tracking. Site staff are excluded by default to keep ad audience data clean. 6. Post Data Export Preview and export monthly post data (including a configurable page-view meta key) as CSV from the admin panel. 7. Homepage Meta Tags & Structured Data Outputs Meta Description, Open Graph social sharing tags (og:title, og:description, og:image, twitter:card), and Schema.org WebSite/Organization JSON-LD on the homepage — a lightweight alternative when no full SEO plugin is installed. Automatically disables its output when a major SEO plugin (Yoast SEO, Rank Math, All in One SEO, SEOPress, The SEO Framework) is detected to prevent duplicate tags. #### Origin Projects This suite grew out of six standalone plugins previously written by the author, consolidated and optimized into one toolkit: * disable-all-thumbnails: https://github.com/ivanusto/disable-all-thumbnails * disable-all-comments: https://github.com/ivanusto/disable-all-comments * zh-to-en-slug: https://github.com/ivanusto/zh-to-en-slug * smart-image-upload-resizer: https://github.com/ivanusto/smart-image-upload-resizer * smart-file-renamer: https://github.com/ivanusto/smart-file-renamer * modern-rss-image-feed: https://github.com/ivanusto/modern-rss-image-feed ### External Services This plugin utilizes third-party and external services to provide specific functionalities: 1. Google Cloud Translation API & Google Translate Public Endpoint: 2. * What it is: Used to translate Asian-language post titles into English lowercase slugs. * Data sent: The text of the post title is sent to Google’s translation endpoints when a post whose title contains Asian-script characters (Chinese, Japanese, Korean, Thai) is created or updated. No personally identifiable information ( PII) or user data is transmitted. * Terms and Privacy: - Google Terms of Service: https://policies.google.com/terms - Google Privacy Policy: https://policies.google.com/privacy 3. Meta (Facebook) Pixel: 4. * What it is: Used for tracking website visitor interactions (PageView, ViewContent, and Search events) for analytics and advertising. * Data sent: Sends visitor interaction data (visited page URL, search queries) to Meta. By default, logged-in site staff (users with `edit_posts` capability) are excluded, and tracking is disabled on feeds, previews, and oEmbed pages. * Terms and Privacy: - Meta Business Tools Terms: https://www.facebook.com/legal/controller_addendum - Meta Privacy Policy: https://www.facebook.com/privacy/policy/ ## Screenshots [⌊SEO & Site Optimization settings tab with toggles for RSS control, HTML head cleanup, robots meta, sitemap sanitization, and XML-RPC hardening.⌉⌊SEO & Site Optimization settings tab with toggles for RSS control, HTML head cleanup, robots meta, sitemap sanitization, and XML-RPC hardening.⌉[ SEO & Site Optimization settings tab with toggles for RSS control, HTML head cleanup, robots meta, sitemap sanitization, and XML-RPC hardening.

Upload the `omni-webmaster-seo-suite` folder to the `/wp-content/plugins/` directory. 2. Activate the plugin through the ‘Plugins’ menu in WordPress. 3. Configure the settings under ‘Settings > Omni Webmaster’. ## FAQ ### Does translation require an API Key? No, an API key is optional. With a Google Cloud Translation API key configured, the official Cloud API is used. If the key is left blank (or a Cloud API call fails), the plugin falls back to the key-less public Google Translate endpoint automatically. ### Does deleting thumbnails delete my original images? No. It only deletes resized sub-sizes. Your original uploaded images remain completely safe. ### Will settings from separate legacy plugins be migrated? No. This plugin uses a clean, unified settings array (`omni_webmaster_settings`) to prevent database clutter. You will need to check the desired options in the new admin settings panel. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “Omni Webmaster & SEO Suite” is open source software.

removed a legacy zip from the repository. #### 2.1.1 * Slug Translator settings now recommend using a Google Cloud Translation API key: the keyless fallback endpoint can produce lower-quality slugs (e.g. `how-was- it-able-9`), and the description links to Google’s API key setup guide. * Refined the zh_TW translation of the Slug Translator description to mention Chinese, Japanese, Korean, and Thai support. #### 2.1 * Interface is now English by default with full internationalization (i18n) support; Traditional Chinese (zh_TW) translation is bundled so existing Chinese sites keep their localized UI. * Slug Translator generalized beyond Chinese: now detects Chinese, Japanese, Korean, and Thai titles, and lets Google Translate auto-detect the source language. * Added directory screenshots and screenshot captions. #### 2.0 * Resolved official WordPress.org Plugin Directory review feedback: removed persistent database updates to core media size options (thumbnail_size_w/h) so core media settings remain intact. * Replaced direct style tag outputs with wp_add_inline_style() calls using version tags for cleaner CSP compliance and caching. * Added External Services section in readme.txt to comply with Guideline 6 regarding Google Translate and Meta Pixel. #### 1.9 * Added XML-RPC Security Hardening option (SEO tab, off by default): removes all WordPress XML-RPC methods (wp.*, metaWeblog.*, blogger.*, mt.*, pingback.*), keeping only system.multicall, system.listMethods, and system.getCapabilities. * Blocks xmlrpc.php credential brute-force (e.g. via wp.getUsersBlogs) and pingback amplification abuse; works on any web server without .htaccess rules. * Removes the X-Pingback response header when hardening is enabled. #### 1.8 * Added Homepage Meta Tags & Structured Data module: outputs Meta Description, Open Graph tags (og:type/site_name/title/description/url/image/locale, twitter: card), and Schema.org WebSite + Organization JSON-LD on the homepage. * Output is limited to the first page of the homepage (paginated pages excluded) to avoid duplicate descriptions across URLs. * Automatic conflict detection: output is suppressed when Yoast SEO, Rank Math, All in One SEO, SEOPress, or The SEO Framework is active, with a notice shown in the settings panel. * Added og:image picker with WordPress media library integration and live preview in the admin panel. * Added live character counter (90-160 recommended range) for the homepage meta description field. * Organization logo uses the Site Icon when set, falling back to the configured share image. * JSON-LD is printed via wp_print_inline_script_tag with wp_json_encode for safe, CSP-friendly output. * Added omni_meta_tags_enabled filter so themes or consent plugins can conditionally disable output. #### 1.7 * Rewrote the Slug Translator module to align with the standalone zh-to-en-slug plugin (v1.2.2) implementation, with shared API-call helpers for the save-time translation and the AJAX key test. * Cloud Translation API requests now ask for plain-text responses (format=text) so HTML entities can no longer pollute generated slugs. * Translation now only runs for an allow-list of post statuses (draft, publish, future, pending, private), customizable via the new omni_slug_allowed_statuses filter. * Plugin settings are now loaded lazily on first use instead of on every page load. * Hardened the AJAX API test endpoint: added a manage_options capability check and escaped all dynamic output. * Generated slugs now keep a minimum length of 8 characters, and the max-length setting is clamped to 20-200 so the ID reserve can no longer truncate slugs to an empty string. * Fixed the OMNI_WEBMASTER_VERSION constant lagging behind the actual plugin version. * Documentation: corrected the API-key FAQ (key-less fallback) and cross-linked the standalone zh-to-en-slug project. #### 1.6 * Optimized Meta Pixel module: settings are now cached per request instead of being re-read on every output hook. * Added “Exclude site staff” option (enabled by default) so logged-in users with edit_posts capability are no longer tracked, keeping ad audience data clean. * Pixel tracking is now skipped on feeds, post previews, customizer previews, and oEmbed pages. * Pixel ID is strictly sanitized to digits only on save and on output. * Added preconnect/dns-prefetch resource hints for connect.facebook.net to speed up fbevents.js loading. * Advanced event parameters (ViewContent/Search) are now encoded with wp_json_encode for safer output. * Inline pixel script is now printed via wp_print_inline_script_tag() for CSP-nonce compatibility. * Fixed unescaped ampersand in the noscript fallback image URL. * Added omni_meta_pixel_enabled filter so themes or consent plugins can conditionally disable tracking. #### 1.5 * Added Meta Pixel tracking integration. * Added PageView, ViewContent (on single posts/pages), and Search tracking. * Added Meta Pixel tracking settings tab and options in admin console. #### 1.4 * Fixed Google Translate API double URL-encoding issue that caused translation failures. * Fixed post slug getting stuck as ‘auto-draft’ when saving Chinese-titled posts. * Excluded ‘auto-draft’ and ‘inherit’ statuses from trigger translation workflow to optimize performance. #### 1.3 * Hardened the oEmbed cache cleanup query (escaped LIKE wildcard, prepared statement) and now flush the object cache after purging so stale embed cards regenerate reliably. * Auto-purge oEmbed failure cache when the “HTML Head Cleanup” or embed-style options change, so degraded embed cards recover without a manual reset. #### 1.2 * Updated version and Tested up to compatibility with WordPress 7.0. * Resolved various official Plugin Check report warnings including database caching, parameter escaping, input sanitization/unslashing, hook prefixing, and WP_Filesystem usage. #### 1.0.1 Fixed settings tab panel display issue where settings were overwritten. Fixed coding standards, text domain mismatches, output escaping, and database query caching. Renamed global initialization function for prefix safety. #### 1.0.0 Initial release. Integrated SEO cleanup, comment block, thumbnail control with AJAX cleanup, and slug translation. ## Meta * Version **2.1.2** * Last updated **15 hours ago** * Active installations **Fewer than 10** * WordPress version ** 6.0 or higher ** * Tested up to **7.0.2** * PHP version ** 7.4 or higher ** * Tags * [comments](https://wordpress.org/plugins/tags/comments/)[performance](https://wordpress.org/plugins/tags/performance/) [seo](https://wordpress.org/plugins/tags/seo/)[thumbnails](https://wordpress.org/plugins/tags/thumbnails/) [translation](https://wordpress.org/plugins/tags/translation/) * [Advanced View](https://wordpress.org/plugins/omni-webmaster-seo-suite/advanced/) ## Ratings No reviews have been submitted yet.
