Shopify product tags: A complete guide for store owners

Shopify product tags are one of the most underused organizational tools in a store’s admin.  Used well, they power automated collections, filter admin views, and enable tag-based marketing automation for your business.

This guide covers what tags are, how to add them to your catalog, what to use them for, and the best practices that make a tagging system useful over time. By the end of this article, you’ll be able to keep your data clean and your campaigns running smoothly.

What are tags in Shopify?

Tags are short text labels you attach to products and other Shopify objects to organize, filter, and automate store management. While you can add tags to orders, customers, blog posts, and draft orders, we’ll focus entirely on product tags in this guide.

Product tags help ecommerce brands manage their catalogs in several ways:

• Organize products in the admin: Filter by tag to quickly find specific product groups.
• Power automated collections: Products with a specific tag automatically appear in a collection without manual curation.
• Integrate with apps: Tags sync with connected tools, including email marketing and SMS campaigns. 
• Enable front-end filtering: Some themes surface tags as filter options on collection pages.

By default, tags are internal labels. Customers don’t see them unless your theme is configured to display them. Shopify allows up to 250 tags per product, which is a generous limit, but the best tagging systems use far fewer tags.

How to add tags in Shopify

There are three main methods for tagging products, and it depends on whether you’re updating individual items or organizing the entire catalog.

Adding tags to a single product

Follow these steps to update an individual item:

1. Go to your Shopify admin and click Products
2. Click the product you want to tag
3. Scroll to the Tags field in the right-hand sidebar
4. Type a tag and press Enter, or type a comma to add it
5. Add multiple tags as needed — separated by commas
6. Click Save

Keep in mind that tags are case-sensitive, so decide on a strict capitalization rule before you start and stick to it.

Adding tags to multiple products at once

Here’s how to apply updates in bulk:

1. Go to your Shopify admin and click Products
2. Select the checkbox next to each product you want to tag
3. Click Actions, then click Add tags
4. Type the tag you want to add
5. Click Save

Bulk tagging is essential when setting up a new tagging system across an existing product catalog, as tagging each product individually isn’t viable at scale.

Adding tags during product import (CSV)

You can also add tags in bulk via CSV import. The Tags column in your file accepts comma-separated values. This is the most efficient method for stores migrating from another platform or setting up a large initial product catalog.

These tags must follow the same formatting conventions as your manually added tags. Otherwise, inconsistent capitalization in a CSV import will eventually create cleanup problems.

What to use Shopify product tags for

Tags are most valuable when used with a clear purpose. Here are the main applications for a Shopify tagging system.

Powering automated collections

It’s by far the most powerful use case of product tags in Shopify.

Automated collections use specific conditions, including tags, to automatically add matching products. A product tagged “summer-2026”, for example, automatically appears in the “Summer Collection” the moment the tag is added.

Manual collections require adding each product individually. Automated tag-based collections update themselves as tags are added or removed, which means no manual maintenance is required.

For example, if a store creates an automated collection with the condition “product tag equals sale”, every product tagged “sale” appears automatically. When the sale ends, removing the tag instantly removes the product from the collection.

Filtering products in the admin

Tags make large product catalogs easier to navigate in the Shopify admin.

You can use the “filter by tag” option to quickly surface product groups for bulk actions, such as price updates, inventory checks, promotion setup, and more. For example, filter by “new-arrival” to see all products added this month and apply a promotional price in bulk.

The practical value of this scales with your catalog size. A store with 50 products doesn’t need tags for navigation, but a store with 5,000 products certainly does.

Triggering marketing automation

Tags sync with connected marketing apps, including Omnisend, where product tags can be used as:

• Segmentation criteria: Segment customers by the tags of the products they have purchased. Customers who bought a product tagged “skincare” can receive a skincare-specific email campaign, which improves your customer lifetime value. 
• Automation triggers: A purchase of a product with a specific tag can trigger a different post-purchase flow. For example, a customer who buys a product tagged “high-value” enters a VIP post-purchase sequence, and a customer who buys a product tagged “first-time offer” enters a new customer nurture flow.

The consistency and logic of the underlying tagging system directly determine the quality of tag-based marketing automation. If you use inconsistent tags, you’ll produce unreliable segments.

Front-end collection filtering

Many Shopify themes support tag-based filtering on collection pages, and customers can filter products by color, size, material, or any other attribute represented as a tag.

This use case does, however, require theme support because some themes don’t natively surface tags as filter options.

For example, if a clothing store tags products with size (size-xs, size-s, size-m) and color (color-black, color-white), customers can filter the collection page by these attributes without a third-party filtering app.

If your store relies heavily on front-end filtering, a consistent tag naming convention is non-negotiable.

Shopify tags best practices

This section distinguishes stores with a working tag system from those whose tag system becomes unmanageable over time.

Establish a naming convention before you start

The single most important tagging decision you can make is to pick a format and stick to it before adding a single tag.

We recommend using all lowercase letters with hyphens, such as “new-arrival,” “sale,” “summer-2026,” “high-value,” etc. This is the most readable and consistent format.

Avoid using spaces, because “new arrival” and “new-arrival” are two completely different tags in Shopify, and it’s a recipe for creating inconsistency over time. Also, don’t use special characters beyond hyphens and underscores.

Remember that case sensitivity matters as well, so a tag labeled “Sale” is different from one labeled “sale”. If your tagging system mixes cases, it’s bound to produce broken collections and unreliable segments. 

Make sure you document your naming convention in a shared reference so every team member can use the same format while adding tags.

Use prefixes to categorize tags by type

As a product catalog grows, tags from different categories become hard to distinguish at a glance. The solution is to use a prefix system and add a category prefix to each tag so its purpose is clear immediately.

Here are a few examples:

• “season-summer” and “season-winter” for seasonal tags
• “promo-sale” and “promo-bfcm” for promotional tags
• “material-cotton” and “material-leather” for material tags
• “audience-VIP” and”audience-new” for audience-targeting tags

There are clear benefits that come with this prefix structure:

1. Admin filtering becomes faster
2. Automated collection conditions are clearer
3. Marketing app segmentation is more reliable. 

It’s especially valuable for stores with large catalogs or multiple team members managing tags.

Audit and clean tags regularly

Tags accumulate over time, which can eventually turn your library into a messy collection of unsupervised tags and categories.

To avoid that, schedule a quarterly tag audit to review all tags across your product catalog, remove outdated promotional tags, standardize inconsistent formatting, and document any new tag categories you add.

Since the Shopify admin doesn’t have a native tag manager, you’ll need to use a bulk product export in CSV format. Once exported, you can review all tags in the catalog at once and identify inconsistencies. 

There are also third-party apps such as Metafields Guru and Bulk Product Edit that can simplify large-scale tag cleanup.

Don’t use tags for data that belongs in metafields

Tags are flat labels, so they don’t have value beyond the text string itself. Data with a structured value, such as dimensions, weight ranges, or warranty period, belongs in metafields rather than tags.

A wrong use case is tagging a product “weight-1.2kg”. This is structured data with a unit of measurement, so it belongs in a metafield. A right use case is tagging a product “heavy” as a relative category label. It’s a flat organizational label that tags handle well.

Tags are for categorization, and metafields are for structured product data. If you use theme interchangeably, you’ll create a messy and hard-to-maintain system.

Keep tags relevant to a clear business purpose

Every tag in your system should serve at least one specific function: powering a collection, enabling admin filtering, triggering marketing automation, or supporting front-end filtering. Tags that serve none of these purposes only add noise with no value.

Before adding a new tag category, ask what this tag will do. If the answer is unclear, the tag doesn’t belong in the system. Try this test if you find yourself unsure: if you removed the tag from every product tomorrow and nothing broke, was the tag really earning its place?

Use Shopify product tags to power smarter marketing with Omnisend

A well-structured Shopify tag system is the foundation of tag-based segmentation and automation in Omnisend.

Omnisend reads Shopify product tags to enable customer segmentation by purchase behavior, product affinity, and collection membership. The more consistent your tag system is, the more precise these segments become.

It allows you to send highly relevant campaigns rather than relying on generic messaging. For example, customers who purchased products tagged “skincare” can receive skincare replenishment campaigns. Likewise, customers who bought “high-value” products automatically enter a VIP flow. 

This level of personalization can help you achieve the average $79 return per $1 spent that Omnisend merchants see.
