Similar and Related Products for JoomShopping 5+
The extension automates the creation of similar and related product lists in JoomShopping. Instead of assigning links manually for every product, you define a selection rule, choose the products to process, specify the donor product source, and run the operation.
For JoomShopping 5+
Below is a step-by-step workflow: from selecting recipient products to running a specific donor selection method.
Key concepts: recipients and donors
To use the extension correctly, first separate products into two roles.
Simple example
If you generate similar products for smartphone A, smartphone A is the recipient. Other smartphones selected by the rule are the donors.
Step 1. Select products to generate relations for
Open the JoomShopping product list. If you only need to process specific products, select them with checkboxes. Then click the Product linking button.
The screenshot shows the selected recipient products. Similar or related product lists will be generated for these products.
You can process more than selected products
The extension also supports bulk processing for products from a category, manufacturer, or vendor. Selecting individual products is useful for testing a rule on a small set first.
Step 2. Choose the relation type
In the Target products section, choose which list should be generated:
Then, in Processing type, choose the method the system should use to find donor products.
Step 3. Choose the product selection method
Each selection method follows the same basic workflow: define the number of products, choose the donor source, set the matching condition, and optionally apply additional quality filters.
By price
Use this mode when similar or related products should be selected relative to the current product price.
Example: add 6 products from the selected segment whose price matches the specified condition relative to the recipient product price.
By product ID
Use this mode when you already know exactly which products should be added.
This mode does not search by properties — it adds exactly the products whose IDs you specify.
By text in product name
Allows products to be selected when their names contain the specified text.
This mode is useful when product names contain consistent words or identifiers for a series, model, or purpose.
By SKU (EAN)
Use this when related products can be identified by a common part of the SKU.
Useful for catalogs where part of the SKU identifies a series, group, manufacturer, or another shared property.
By characteristics
One of the most flexible modes. It allows products to be linked by one or more characteristics.
In AND mode, a product must match all specified characteristics; in OR mode, matching any one of them is enough.
By labels
Selects products by JoomShopping labels.
In the older interface, multiple selection is done while holding Ctrl; in newer versions, use the current multi-select control.
Random selection
Generates a list of randomly selected products from the specified donor segment.
This method does not search for similarity by a specific property — it randomly selects products from the allowed segment.
Step 4. Define the donor product segment
In most modes, you can limit exactly where the system may take products from for the generated list.
Why limit the donor segment
The more precisely the donor source is defined, the more predictable the result will be.
Step 5. Enable product quality filters
Before running the process, define which products are allowed to be added to the recommendation list.
Step 6. Run processing
After selecting the relation type, matching method, number of products, donor segment, and add conditions, click Process.
Test the rule first
Before processing a large catalog, it is better to select a few recipient products, run the linking process, and verify the result on the product pages.
Practical scenarios
Installation and updates
Install the extension using Nevigen Installer. After installation, enter the license key for the domain specified in the order.
Updates
Nevigen Installer is recommended for updating Nevigen extensions because it shows update availability and additional information before installation.
Support
If the automatically generated result is not what you expected, check which products are selected as recipients, which processing type is used, which donor segment is defined, how many products should be added, and which quality conditions are enabled.
