If you only need the bar to be displayed on specific pages of a certain category of products, such as different shoes or different T-shirts, it would be very inconvenient to choose the required pages from page targeting.

You can use the product targeting feature, which can be very convenient and efficient to complete this task.

Firstly, you need to add the same tag to your target products.

Step1：Go to the Products page in your Shopify admin.

Step2：Select the product you want and add the desired tags.

Once you have added product tags to all the products that you need to display bars for, please proceed to use product targeting in the app to publish the bar.

Step1：Go to the editing page of the bar.

Step2：Select Targeting Configuration.

Step3：In the Page Targeting, select to display the bar on All pages.

Step4：In the Product Targeting, choose to Target products based on product tags, then add your product tags.

After this setup, the bar will only be displayed on the product pages where you have added a tag.
