There are two types of tags that can be used in WooCommerce – product tags and post tags. Product tags are used to describe products in your WooCommerce store, and post tags are used to describe blog posts.
Product tags can be used to help customers find products that are similar to ones they have viewed or purchased before. They can also be used to up-sell and cross-sell products. For example, if a customer has bought a dress from your store, you could use a product tag to suggest other items of clothing that would go well with the dress, such as a scarf or a pair of earrings.
Post tags can be used to categorize your blog posts. This is useful for both customers and search engines, as it helps them to find relevant content more easily. You can add post tags to your blog posts when you edit them in the WordPress editor.
To sum up, tags are a useful way of organizing products and content in WooCommerce stores. They can help customers find what they’re looking for, and they can also help boost your store’s SEO.
