# Products groups
After setting up the [Placement](/recommendations-and-merchandising_deprecated/recommendations/introduction/placement.md), the next step is to define the product groups for your recommendation. These groups determine how products are selected and displayed in your recommendations.
### Step 1: Define Product Blocks
#### Rename Product Blocks:
Each product group is represented by a block. You can rename these blocks to reflect their purpose or the type of products they include.
*Example: Rename blocks as "Most Viewed", "New Arrivals", or "Bestsellers".*
#### Algorithm Selection:
Assign an algorithm to each block. The algorithm determines which products are included in that block (e.g., most viewed, recently added, bestsellers).
The final recommendation will concatenate the results from all blocks in sequence:
* Products from Block 1 + Products from Block 2 + Products from Block 3, etc.
[Discovery Default Algorithms](/recommendations-and-merchandising_deprecated/recos-and-merch-algorythms/default-algorithms.md)
### Step 2: Advanced Configuration (Optional)
#### Access Advanced Options:
* Click the ‘Advanced’ button beneath each product block to configure it further.\
Set Product Limits:
* Limit the number of products displayed for each block by adjusting the settings under the tabs named after your blocks.
*Example:*\
\&#xNAN;*Block 1: Display up to 5 products from "Most Viewed".*\
\&#xNAN;*Block 2: Display up to 5 products from "New Arrivals".*\
\&#xNAN;*Block 3: Display up to 5 products from "Bestsellers".*
#### Shuffle Products:
Enable the option to randomly shuffle the products within a block to add variety.
### Step 3: Adjust Display Order
Use the drag-and-drop system to rearrange the order of your blocks.\
The display order of products in the recommendation will reflect the order of your blocks.
*Example Configuration*\
\&#xNAN;*Block Names:*
*Block 1: Test 1 (Best Views – Limit: 5 Products).*\
\&#xNAN;*Block 2: Test 2 (Products viewed by the user – Limit: 5 Products).*\
\&#xNAN;*Block 3: Test 3 (Bestsellers – Limit: 5 Products).*\
\&#xNAN;*Result: The final recommendation will display:*
*5 Most Viewed products, followed by*\
\&#xNAN;*5 Products viewed, and finally*\
\&#xNAN;*5 Bestsellers.*
*Total Display: The recommendation is limited to 15 products.*
### Step 4: Preview Your Configuration
At any point, click the ‘Preview’ button in the top-right corner to visualise the results of your changes.\
Use the preview to ensure the recommendation meets your expectations.
### Step 5: Save Your Changes
Once you’re satisfied with the configuration, click the ‘Save’ button to finalise your settings.
**Additional Configuration Options**\
You can further refine your recommendation by exploring the following options:
* [**Placement**](/recommendations-and-merchandising_deprecated/recommendations/introduction/placement.md): Define where the recommendation will appear on your website.
* [**Filters:**](/recommendations-and-merchandising_deprecated/recommendations/introduction/filters.md) Apply filters to refine the product selection based on criteria like price, category, or stock.
* [**Products Highlight:**](/recommendations-and-merchandising_deprecated/recommendations/introduction-1/products-highlights.md) Pin specific products to feature them prominently in the recommendation.
* [**Exceptions:** ](/recommendations-and-merchandising_deprecated/recommendations/introduction/exceptions.md)Add dynamic rules to tailor recommendations based on specific triggers or conditions.
* [**Options:**](/recommendations-and-merchandising_deprecated/recommendations/introduction/options.md) Customise additional settings, such as excluding cart items or setting a fixed number of products.
#### Final Notes
* Configuring product groups allows you to create targeted and dynamic recommendations that align with your business goals.
* Regularly review and adjust your blocks to reflect changing trends or priorities.
* For further assistance, refer to the platform documentation or contact your **Customer Success Manager (CSM)**.
