## 📥 Installation

1. Upload the plugin folder to `/wp-content/plugins/`

2. Activate the plugin via **Plugins > Installed Plugins**

3. Go to **Tools > Duplicate Post Manager**

---

## 🚀 How to Use

### 📍 Step 1: Scan for Duplicates

- Navigate to **Tools > Duplicate Post Manager**

- Select a content type:

  - Posts, Pages, Custom Post Types

  - Media Library

  - Categories

- Click **Scan for Duplicates**

### ✅ Step 2: Review and Select Duplicates

- Duplicates will appear in a table

- For each:

  - Check the box to delete

  - (Posts/Pages only) Choose a redirect target:

    - Select from other duplicates

    - Or enter a manual URL

> ⚠️ Media and categories are delete-only — no redirects.

### 🗑️ Step 3: Process

- Click **Delete Selected & Redirect**

- Posts will be sent to trash

- Redirects will be saved and added to `.htaccess` output

---

## 📜 .htaccess Management

Go to **Tools > .htaccess Manager** to:

- View generated redirect rules

- Write them directly into your real `.htaccess` file

- Clear all stored redirects

- Download `.htaccess` backup

---

## 💾 .htaccess Backup/Restore

Go to **Tools > .htaccess Backups** to:

- One-click backup your current `.htaccess` to `/uploads/htaccess-backups/`

- Restore the last backup anytime

---

## 📥 CSV Export

- Each time you scan, a CSV file is saved to `/wp-content/uploads/advanced-duplicate-posts.csv`

- After scanning, a **Download Duplicates CSV** button will appear

- Useful for keeping audit logs or pre-approval before deletion

---

## 🔒 Best Practices

- 🔄 Always **back up `.htaccess`** before writing changes

- 📁 Only assign redirects to valid, working URLs

- ✅ Let the plugin check for 404s — it won’t save invalid redirects

- 🧹 Delete media duplicates with caution — this cannot be undone

- 🧪 Test in staging before cleaning large content batches

---

## 🧠 Why Use This Plugin?

- Prevent SEO penalties from duplicate content

- Safely redirect deleted pages instead of serving 404s

- Keep your database and media library lean and organized

- Avoid slug collisions and orphaned content

- Maintain editorial and audit control with CSV logs

---

## 💼 Use Cases

- Bulk-imported WordPress sites with many auto-generated posts

- Migrated content from older CMSs

- eCommerce or directory sites with repeated titles or categories

- Media-heavy sites needing cleanup of duplicate images

---

## ❓ FAQ

**Q: Can I use this for WooCommerce products?**  

A: Yes! Products are a custom post type. Just select them from the dropdown.

**Q: Are deleted posts permanently removed?**  

A: No — posts/pages are moved to trash. Media is permanently deleted.

**Q: Does it affect SEO?**  

A: In a good way! 301 redirects preserve SEO value by avoiding 404s.
