Problem

Currently, website scan happens only once during business creation.

If the website later:

• Adds new pages

• Updates existing pages

• Changes structure

There is no way to re-scan.

The only option is:
Delete business → Add again → Full re-scan

This causes:

• Credits wasted on already scanned pages

• Loss of historical data

• Poor user experience

• Not scalable for growing websites

What We Need

1️⃣ Manual Incremental Re-Scan

Add a “Re-Scan Website” button inside each Business.

When user clicks Re-Scan:

1. Crawl website again

2. Compare with previously scanned pages

3. Detect:

• ✅ New pages → Scan + deduct credits

• 🔁 Existing pages → Skip (no credits)

• 📝 Changed pages (optional) → Scan only if needed

• ❌ Deleted pages → Mark as inactive

Important:

• Do NOT delete existing data

• Do NOT consume credits for already scanned pages

• Show how many credits will be used before confirming

Example UI message:

We found 5 new pages.
Credits required: 5
Do you want to continue?

2️⃣ Automatic Change Detection

Add option to automatically detect website changes.

How it works:

System periodically checks:

• Sitemap

• Page URLs

• Content changes

If new pages are detected:

Option A:
Notify user:

We found 3 new pages. Scan now?

Option B:
If Auto-Scan is enabled → scan automatically and deduct credits.

Business Settings Additions

Under Website Settings:

• Enable Auto-Scan for New Pages

• Scan Frequency: Weekly / Monthly

• Auto-scan changed pages: Yes / No

Acceptance Criteria

• User can re-scan without deleting business

• Only new pages consume credits

• Existing pages remain untouched

• Historical data stays intact

• Clear credit preview before scan

• Auto-scan toggle works

• System logs scan timestamp per page

Why This Matters

• Saves credits

• Protects user data

• Supports growing websites

• Reduces churn

• Makes ClickGrow scalable
