# Managing Duplicate Products

If your store is **not on Shopify Plus**, Eraya uses **duplicate products** to safely run price tests without affecting live listings. This requires a few one-time setup steps to ensure your storefront, inventory, and third-party integrations work smoothly.

## Remove Duplicate Products from Sales Channels

To prevent duplicate test products from appearing on your sales channels (like Facebook, Google, or POS), keep them active only in your **Online Store** channel.

{% stepper %}
{% step %}

### Locate test products

* Go to **Shopify → Products**.
* In the search bar, type your test tag:

```
eraya-price-test-<testId>
```

Example: `eraya-price-test-68c6e8d04c4e505e4f18ea4e`
{% endstep %}

{% step %}

### Select duplicate products

* Select the duplicate product(s) by clicking the checkbox in the product list.
  {% endstep %}

{% step %}

### Exclude from sales channels

* Click the **three dots (⋯)** above the product list.
* Choose **“Exclude from sales channels.”**
* In the popup window:
  * De-select “Online Store.”
  * Keep all other channels selected.
* Click **“Exclude products.”**
  {% endstep %}
  {% endstepper %}

***

## Remove Duplicate Products from Collections

To avoid showing duplicate products in your store collections, remove them from all existing collections.

{% stepper %}
{% step %}

### Find duplicate products

* Go to **Shopify → Products**.
* Search for your test tag:

```
eraya-price-test-<testId>
```

{% endstep %}

{% step %}

### Select duplicate products

* Select the duplicate product(s) by clicking the checkbox.
  {% endstep %}

{% step %}

### Remove from collections

* Click the **three dots (⋯)** above the product list.
* Choose **“Remove from collection(s).”**
* In the popup:
  * Select all collections.
* Click **“Save.”**
  {% endstep %}
  {% endstepper %}

***

## Inventory Tracking

Eraya automatically keeps inventory synchronized between your **duplicate** and **original** products.

{% hint style="info" %}
No action required — Eraya handles inventory synchronization:

* Real-time stock adjustments
* Updates on purchases, refunds, and restocks
* Prevention of mismatched inventory or overselling
  {% endhint %}

***

## Configure Search App

If your store uses a **search app** (e.g., Boost, Searchanise, InstantSearch+), set a rule to hide duplicate test products.

{% stepper %}
{% step %}

### Open search app settings

* Open your search app’s settings or filters.
  {% endstep %}

{% step %}

### Exclude duplicates

* Add a rule to **exclude** any product with the tag:

```
eraya-duplicated
```

{% endstep %}

{% step %}

### Save and reindex

* Save and reindex the search results.
  {% endstep %}
  {% endstepper %}

***

## Configure Duplicate Products in Third-Party Apps

If your store uses additional third-party apps that reference products, make sure to **add your duplicate products** to those apps.

Examples:

* Review apps: Judge.me, Loox, Yotpo
* Size chart apps
* Bundle or Upsell apps
* Frequently Bought Together apps
* Subscription apps: Recharge, Skio, Appstle

Adding your duplicate products ensures these apps display accurate data for all test variants.

***

## Hide Duplicate Products from Collection Pages (Theme Edit)

If your storefront theme displays products from collections, you can hide duplicate test products directly in your theme code.

{% stepper %}
{% step %}

### Open theme code editor

* In Shopify Admin, go to **Online Store → Themes → Edit Code.**
  {% endstep %}

{% step %}

### Find collection template

* Find the file that renders collection pages (example filenames):
  * `collection.liquid`
  * `collection-template.liquid`
  * `main-collection-product-grid.liquid`
  * `collection-page.liquid`
    {% endstep %}

{% step %}
\## Locate product loop

* Locate the product loop in the template:

```liquid
{% for product in collection.products %}
  ...
{% endfor %}
```

{% endstep %}

{% step %}
\## Wrap rendering in an unless block

* Wrap the existing product display code inside an `unless` block:

```liquid
{% unless product.tags contains "eraya-duplicated" %}
  <!-- existing product display code -->
{% endunless %}
```

* Click **Save** and preview your collection page.
  {% endstep %}
  {% endstepper %}
