📋 Requirements

  • WordPress 5.8 or higher
  • PHP 7.4 or higher
  • Pretty permalinks enabled (or write access to the site root for a physical key file)
  • OpenSSL extension (required for encrypting the Google JSON key)

🚀 Installation

  1. Upload the milyutin-instant-indexer folder to wp-content/plugins/ (or upload a ZIP file via Plugins → Add New → Upload Plugin).
  2. Activate the plugin. Upon activation, it automatically generates an IndexNow key, registers rewrite rules, and schedules WP-Cron tasks.
  3. Go to the Instant Indexer menu and follow the on-screen instructions (the "Setup Instructions" section covers both IndexNow and Google).

🔒 Security Settings API: All forms use settings_fields() (nonce) and options.php (capability checks).

AJAX Security: All AJAX requests are protected by check_ajax_referer() and current_user_can( 'manage_options' ).

Data Encryption: The Google service account JSON is stored in a separate option (autoload = false) encrypted via AES-256-CBC + HMAC-SHA256. Keys are derived from WordPress salts and are never exposed in the UI.

Safe Logging: Logs never contain secrets. Private keys, JWTs, and access tokens are automatically masked.

File Protection: Log files are protected by .htaccess and index.php. The physical key file is restricted to /{key}.txt.

❓ Troubleshooting Symptom Cause & Solution IndexNow 403/404 Key file is inaccessible. Enable pretty permalinks, clear cache, or create a physical key file. IndexNow 422 URL doesn't belong to your site's domain. Check "Settings → General" and www prefix. IndexNow 202 Key is still being verified. The plugin will automatically retry the request. Google 403 Service account email isn't added as an Owner in Search Console, or Web Search Indexing API isn't enabled. Google 429 Daily quota (200) exceeded. URLs will be queued and processed automatically later. "Failed to decrypt JSON" WordPress salts changed in wp-config.php. Please re-upload the JSON key.
