## 説明

N.C Decay Scanner is a free content decay scanner by Neon.Computer. N.C stands for
Neon.Computer, the publisher of the Decay Scanner and Decay Fixer product family.

The plugin connects to Google Search Console, scans published WordPress content,
identifies pages losing clicks, impressions, or average position, and gives editors
a prioritized opportunity queue inside WordPress.

N.C Decay Scanner is fully functional as a free scanner. N.C Decay Fixer is a separate
premium product available from Neon.Computer for teams that want AI refresh briefs,
draft workflows, alerts, and premium support.

#### Key Features

 * Google Search Console connection.
 * Live scans for posts and pages.
 * Opportunity scoring for click loss, impression loss, ranking movement, and demand.
 * Dashboard health summary and scan history.
 * Opportunity queue with filters, saved views, owners, workflow statuses, and notes.
 * CSV export for scan opportunities.
 * Optional scheduled scans using WP-Cron.
 * Demo data for previewing the workflow before connecting Search Console.

### External Services

N.C Decay Scanner connects to external services only when a site administrator uses
the related feature.

 * Google Search Console: used for OAuth sign-in, property selection, and Search
   Console performance data. The plugin sends the connected site’s OAuth tokens 
   and selected property to Google APIs. Google terms: https://policies.google.com/
   terms and privacy policy: https://policies.google.com/privacy.
 * N.C Connect: the hosted connection service at https://decayfixer.neon.computer/
   helps users connect Google Search Console without creating their own Google Cloud
   app. This service is provided by Neon.Computer. It receives connection state,
   site URL, and token data needed to complete the Google OAuth flow when an administrator
   clicks Connect Google. Terms: https://support.neon.computer/policies.php#terms
   and privacy policy: https://support.neon.computer/policies.php#privacy.
 * Neon.Computer Support Hub: used when an administrator opens support or documentation
   links at https://support.neon.computer/. Support requests may include the site
   URL, plugin version, and details entered into support forms. Terms: https://support.
   neon.computer/policies.php#terms and privacy policy: https://support.neon.computer/
   policies.php#privacy.

The plugin does not send Search Console or support data on activation. Connections
are initiated by a site administrator from the plugin screens.

## インストール

 1. Upload `nc-decay-scanner.zip` from Plugins > Add New > Upload Plugin.
 2. Activate N.C Decay Scanner.
 3. Open N.C Decay Scanner > Setup.
 4. Connect Google Search Console and choose the property for this site.
 5. Run a live scan or load demo data to preview the workflow.

## FAQ

### Is Google Search Console required?

Live scans use Search Console performance data. Demo data is available if you want
to preview the workflow first.

### Does the dashboard call Google every time it loads?

No. Google Search Console is queried when a live scan, single URL scan, property
refresh, or scheduled scan runs. Dashboard views, filters, workflow screens, and
exports read the latest saved scan results from the site owner’s WordPress database.

### Where is scan data stored?

Processed opportunity rows, last-scan metadata, and up to 10 scan history summaries
are stored locally in WordPress options. Search Analytics API responses are cached
briefly with WordPress transients to reduce duplicate Google API calls. Settings
include controls to clear temporary Search Console cache and saved scan results.

### Is this the same as N.C Decay Fixer?

No. N.C Decay Scanner is the free scanner. N.C Decay Fixer is a separate premium
product from Neon.Computer for AI refresh briefs, draft workflows, alerts, and premium
support.

### Can I disconnect external services?

Yes. Search Console can be disconnected from the plugin settings at any time.

### Where do I get support?

Use the support links inside the plugin or visit https://support.neon.computer/.
