The Similar by Tag add-on provides you with new abilities such as:

  • automatically link products to each other by specifying matching tags
  • recommend products that are similar to the viewed one

  • limit the maximum number of products shown per page

To learn how to create a block for similar products, add tags and link products to each other, follow quick and easy steps below.

Managing in the admin panel

Installing the add-on

Install the “Similar by Tag” add-on on the add-ons list page (“Add-ons” → ”Manage add-ons”). Click the + button in the top right corner, select an archive and click Upload & install. You can now find the installed add-on in the list of installed add-ons, just make sure it is set to Active.


For correct operation of the “Similar by Tag” add-on, make sure that the Tags add-on is installed and set to Active on the add-ons list page.

Creating blocks

In order to display similar products on the product page, let’s add a block.

Go to Design - Layouts and open Products tab. Locate the Main Content block and click the + button to add a new block.

In the opened pop-up window, open the Create new block tab and select Products.

In the General tab enter the name of the block and select the template type you like.

In the Content tab set Filling to Tags, specify the number of products you want to display per page in the Limit field and click Create.

You should see the created block on the editing layout page.

You can also add a block with products by tag to a page, if necessary. For example, you have a page containing an article about cotton clothing. So, you add the ‘cotton’ tag both to the page and cotton products from your store and these products will be displayed in a block on the corresponding page.

Go to the Pages tab on the same page, locate the Main Content block and click the + button to add a new block.

In the opened pop-up, select the previously created block or create a new one.

Adding tags

In order to add tags to products, go to Products - Products, select the desired product and open the Tags tab. Enter tags to the Tags field, by clicking Enter each time you add a new tag.

When you specify the same tags for products, they will be displayed as similar products for each other.
