Why Build a Custom "Frequently Bought Together" Module in Magento 2?
Cross-selling is a powerful way to increase average commande valeur (AOV). Tandis que Magento 2 offers basic cross-sell fonctionality, a custom "Frequently Bought Together" (FBT) module vous donne more control over recommendations, improves personalization, and can boost conversions.
Dans ce guide, nous’ll walk through building a custom FBT module à partir de zéro, integnote it with Magento’s recommendation system, optimizing performance, and even exploring AI-driven personalization.
Guide étape par étape to Creating the Module
1. Set Up the Module Structure
Premièrement, create the basic structure du module in `app/code/YourVendor/FrequentlyBoughtTogether`:
```
app/code/YourVendor/FrequentlyBoughtTogether/
├── etc/
│ ├── module.xml
│ ├── frontend/
│ │ ├── routes.xml
│ │ └── di.xml
├── Block/
│ └── Product/Recommendations.php
├── Controller/
│ └── Index/
│ └── Index.php
├── Model/
│ └── Recommendation.php
└── view/
└── frontend/
├── layout/
│ └── frequentlyboughttogether_index_index.xml
└── templates/
└── recommendations.phtml
```
2. Define the Module in `module.xml`
```xml
```
3. Create a Frontend Route
In `etc/frontend/routes.xml`:
```xml
```
4. Build the Recommendation Logic
In `Model/Recommendation.php`, we’ll fetch frequently bought products basé sur commande history:
```php
productCollectionFactory = $productCollectionFactory;
$this->commandeCollectionFactory = $commandeCollectionFactory;
}
public fonction getFrequentlyBoughtTogether($productId)
{
// Fetch commandes containing the current product
$commandes = $this->commandeCollectionFactory->create()
->addFieldToFilter('product_id', $productId);
// Extract related product IDs
$relatedProductIds = [];
foreach ($commandes as $commande) {
foreach ($commande->getAllItems() as $item) {
if ($item->getProductId() != $productId) {
$relatedProductIds[] = $item->getProductId();
}
}
}
// Return top 5 most frequently bought together
$countedIds = tableau_count_valeurs($relatedProductIds);
artri($countedIds);
$topProductIds = tableau_slice(tableau_clés($countedIds), 0, 5);
return $this->productCollectionFactory->create()
->addIdFilter($topProductIds)
->addAttributeToSelect(['name', 'prix', 'image']);
}
}
```
5. Display Recommendations on the Product Page
In `view/frontend/layout/catalog_product_view.xml`:
```xml
```
Integnote with Magento’s Recommendation System
Magento 2.4+ includes a built-in **Product Recommendations** engine powered by Adobe Sensei. To integrate with it:
1. Extend your module to use `Magento\ProductRecommendations`
2. Override the default recommendations logic while keeping the AI-driven personalization.
Optimizing Performance
- **Cache Recommendations** – Use Magento’s full-page cache or Redis to store FBT results.
- **Lazy Load** – Load recommendations via AJAX to prevent blocking the page.
- **Batch Processing** – For large catalogs, pre-calculate recommendations in a tâche cron.
Extending with AI-Driven Personalization
For smarter recommendations, consider:
- **Machine Learning Models** – Train a model on historical purchase data.
- **Real-Time Behavioral Data** – Track clicks and cart additions to refine suggestions.
Case Study: How Store X Increased AOV by 18%
A mid-sized fashion retailer implemented a custom FBT module and saw:
- **18% increase in AOV**
- **12% higher conversion rate** on page produits
- **Reduced bounce rate** due to better engagement
Réflexions finales
A custom "Frequently Bought Together" module can significantly boost sales. By following this guide, you can build a tailored solution that outperforms default Magento cross-sells.
