## Description

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.

#### Google Indexing API and Google OAuth

 * Used for: authenticating with a Google service account and submitting URL update/
   delete notifications.
 * Data sent: JWT assertion to obtain an access token; then public content URLs 
   and notification type (`URL_UPDATED` / `URL_DELETED`) to the Indexing API.
 * Endpoints: `https://oauth2.googleapis.com/token`, `https://indexing.googleapis.
   com/v3/urlNotifications:publish`
 * Terms of Service: https://developers.google.com/terms
 * Privacy Policy: https://policies.google.com/privacy

#### Bing IndexNow

 * Used for: submitting URLs to Bing via IndexNow.
 * Data sent: your IndexNow key, key file location, host, and the list of public
   URLs being submitted.
 * Endpoint: `https://www.bing.com/indexnow`
 * Terms of Service: https://www.microsoft.com/servicesagreement
 * Privacy Policy: https://privacy.microsoft.com/privacystatement

#### IndexNow (alliance endpoint)

 * Used for: submitting URLs through the public IndexNow API shared by participating
   search engines.
 * Data sent: your IndexNow key, key file location, host, and the list of public
   URLs being submitted.
 * Endpoint: `https://api.indexnow.org/indexnow`
 * Terms of Service / Privacy: https://www.indexnow.org/terms

#### Yandex IndexNow

 * Used for: submitting URLs to Yandex via IndexNow.
 * Data sent: your IndexNow key, key file location, host, and the list of public
   URLs being submitted.
 * Endpoint: `https://yandex.com/indexnow`
 * Terms of Service: https://yandex.com/legal/webmaster_termsofuse/
 * Privacy Policy: https://yandex.com/legal/confidential/

#### Baidu URL submission API

 * Used for: pushing public URLs to Baidu Search Resource Platform for faster discovery.
 * Data sent: configured site host, API token, and the list of public URLs in the
   request body.
 * Endpoint: `http://data.zz.baidu.com/urls`
 * Terms / legal notices: https://www.baidu.com/duty/
 * Privacy Policy: https://www.baidu.com/duty/yinsiquan.html

#### Toutiao (ByteDance) auto-push script

 * Used for: loading the official Toutiao webmaster auto-inclusion script so visiting
   browsers can help Toutiao discover page URLs.
 * Data sent: when the feature is enabled, visitors’ browsers request the allowlisted
   Toutiao/ByteDance CDN script URL you configured; the script may observe the current
   page URL in the visitor browser context according to Toutiao’s own script behavior.
 * Typical CDN hosts: ByteDance/Toutiao CDN domains such as `*.bytegoofy.com`
 * Terms of Service: https://www.toutiao.com/user_agreement/
 * Privacy Policy: https://www.toutiao.com/privacy_protection/

## Installation

 1. Upload the `lesep` folder to `/wp-content/plugins/` or install the ZIP from the
    WordPress admin.
 2. Activate **lesep**.
 3. Open **Settings  Search Engine Submission**, enable the engines you need, and save
    API credentials.
 4. Configure auto-submission options on the **General** tab.
 5. Use **Test connection** on each engine to verify credentials.

If you previously used the `webmastersubmit` plugin, settings are migrated automatically
on load.

## FAQ

### Will this submit all old posts automatically?

No. Auto submission runs only when you publish, schedule publish, update published
content, or delete/trash supported post types. Use **Batch Submit** to manually 
push historical URLs.

### Baidu returns “site init fail”. What should I do?

The `site` value must be a plain domain such as `www.example.com` without `http://`
or `https://`, and it must exactly match the site verified in Baidu Webmaster Tools.

### Google test fails but other engines work. Why?

The Google Indexing API is mainly intended for specific URL types such as job postings
and broadcast events. Generic blog posts may be rejected by Google even when credentials
are valid.

### How does Toutiao work?

Paste the auto-push JavaScript from Toutiao Webmaster Tools into the Toutiao engine
settings. The plugin extracts only HTTPS script URLs on allowlisted Toutiao/ByteDance
CDN hosts and outputs a safe external `<script src>` tag in the frontend `<head>`.
Arbitrary inline JavaScript is not executed.

### What happens on uninstall?

Options, pending queue data, logs, scheduled events, and Google token transients
are removed.
