LeSEP – 多合一搜索引擎提交插件

LESEP helps WordPress site owners notify search engines when content is published, updated, or removed. It supports multiple search providers from one settings screen.

Supported search engines

• Google — Indexing API with a service account JSON key
• Bing — official IndexNow endpoint
• IndexNow alliance — public IndexNow endpoint for multiple engines
• Yandex — IndexNow endpoint for Yandex Search
• Baidu — active URL push API from Baidu Webmaster Tools
• Toutiao — auto-push script from Toutiao Webmaster Tools (only allowlisted CDN script URLs are output)

IndexNow-based engines can share one API key. The plugin can serve a virtual {key}.txt file so you do not need to upload it manually.

Key features

• Event-based auto submission — only pushes when you publish, schedule publish, update published posts, or delete/trash content. Existing site content is not scanned or re-submitted automatically.
• Async queue — URLs are queued and submitted via WP-Cron without blocking post saves.
• Manual batch submit — paste up to 500 URLs per request on a dedicated admin tab.
• Connection tests — test API credentials from the admin screen.
• Key file check — verify IndexNow key files are publicly reachable.
• Submission logs — charts, recent entries, export to JSON/CSV, delete and clear actions.
• Encrypted secrets — API keys, tokens, and JSON credentials are encrypted before storage.
• Migration — imports settings from the legacy webmastersubmit plugin slug.

External services

This plugin connects to third-party search-engine APIs and CDNs so it can notify those services about your content URLs. No visitor personal profiles are collected by the plugin itself. When an enabled engine runs, the plugin may send the public post/page URLs of your site (and, where required by the provider, your configured site host, API token/key, or OAuth credentials). Data is sent only when you enable an engine and a submit action occurs (publish/update/delete auto-queue, manual batch submit, or connection test), except Toutiao which loads its script on frontend page views while enabled.
