How to Add Filter by Tags in WooCommerce?

Product tags help shoppers narrow products by style, theme, collection, or use case when categories feel too broad. They add another layer of product discovery and make it easier to connect related items across different parts of the store.

In this guide, you will learn how to add filter by tags in WooCommerce, and which setup methods work best for different store types. You will also see when tag filters make sense, how to prepare tags before setup, and what to watch for in usability and SEO.

Quick Answer

To add a filter by tags in WooCommerce, most stores use a filter plugin or a custom setup that supports frontend tag filtering. A plugin-based method is usually the easiest option because it gives you better control over how tags appear and how shoppers use them on shop or category pages.

• Install a WooCommerce filter plugin that supports product tags
• Enable the Product Tags filter from the plugin settings
• Place the filter on your shop or category page
• Save changes and test the filter on the front end

What a Tag Filter Does in WooCommerce?

Tag filters help shoppers narrow products by shared themes that do not always fit into your main category structure. They are useful for things like style, collection, season, occasion, or product use case, especially when those traits connect products across different categories.

Someone browsing a fashion store, for example, might use tags like Summer, Casual, or New Arrival to explore related products more naturally. That makes product discovery more flexible and helps shoppers find matching items without depending only on categories.

When Tag Filters Are the Right Choice?

Tag filters work best when shoppers need a flexible way to explore products beyond your main category structure. They are more useful for discovery than for store navigation, especially when products share themes, styles, or use cases across different categories.

• Products are connected by style, occasion, theme, or collection
• Shoppers browse by trends or use cases rather than product type
• Tags help link related products across multiple categories
• Visitors need a looser discovery path before narrowing further
• The catalog includes seasonal, promotional, or themed product groups

Set Up Product Tags Before Adding the Filter

Tag filtering only works well when the store already has a clear tag structure behind it. Before adding the filter itself, make sure your product tags are created properly and assigned to the right products. That way, the filter helps shoppers discover related items instead of showing random or unhelpful tag groupings.

• Go to Products → Tags
• Create the product tags your store actually needs
• Use clear, shopper-friendly tag names
• Keep tag usage consistent across similar products
• Assign tags to the right products before adding the filter

How to Add Filter by Tags in WooCommerce?

You can add a tag filter in WooCommerce in a few different ways, depending on how your store is built. Some setups support it through blocks, while others need a plugin or custom code to make tag-based filtering work properly on the front end. Below are the main methods to choose from.

Method 1: Add a Tag Filter Using a WooCommerce Filter Plugin

A filter plugin is the most practical way to add tag-based filtering on the front end. For stores that need more flexible WooCommerce product filters, this method gives you better control over how tags appear, how results update, and where the filter is placed.

Step 1: Install and Activate the Plugin

• Go to Plugins → Add New
• Search for Dynamic AJAX Product Filters for WooCommerce
• Click Install Now
• Click Activate

Pro version:

• Purchase the pro version from the official website
• Download the plugin ZIP file
• Go to Plugins → Add New → Upload Plugin
• Upload the ZIP file, install it, and activate it

Step 2: Enable the Tag Filter

• Go to Product Filters → Form Manage
• Find the Show Tags option
• Turn it on

Step 3: Choose the Tag Filter Style

• Go to Product Filters → Form Style
• Select Tags from the filter dropdown
• Choose a filter style for the tag filter
• Adjust the related display settings if needed
• Configure the Optional and advance setting

Step 4: Save and Display the Filter

• Click Save
• Copy the [[plugincy_filters]] shortcode
• Paste it into your shop page, category page, or filter area where you want it to appear

Step 5: Test the Filter on the Front End

• Open the page where the filter is placed
• Click different tags and confirm products update correctly
• Test the filter on both desktop and mobile

Method 2: Add a Tag Filter With Custom Code

Custom code is a better fit when you want full control over how tag filtering works on the front end. It gives you more flexibility over query logic, layout placement, and filter behavior, but it also takes more effort to build and maintain.

Step 1: Open Your Theme Functions File

• Open your theme’s functions.php file or use a small custom plugin
• Avoid editing WooCommerce core files directly
• Use a child theme if you are adding code through the theme

Step 2: Add the Tag Query Logic

Use this code to filter shop and category pages by a selected product tag from the URL:

add_action(‘pre_get_posts’, ‘custom_filter_products_by_tag’);

function custom_filter_products_by_tag($query) {

if (is_admin() || !$query->is_main_query()) {

return;

}

if (!is_shop() && !is_product_category()) {

return;

}

if (!empty($_GET[‘filter_tag’])) {

$tag_slug = sanitize_text_field($_GET[‘filter_tag’]);

$tax_query = (array) $query->get(‘tax_query’);

$tax_query[] = array(

‘taxonomy’ => ‘product_tag’,

‘field’ => ‘slug’,

‘terms’ => $tag_slug,

);

$query->set(‘tax_query’, $tax_query);

}

}

Step 3: Create the Front-End Tag Filter

Add this code where you want the filter to appear, such as before the product loop in your shop template:

$product_tags = get_terms(array(

‘taxonomy’ => ‘product_tag’,

‘hide_empty’ => true,

));

?>

<form method=”get” action=””>

<select name=”filter_tag” onchange=”this.form.submit()”>

<option value=””>Filter by tag</option>

<?php foreach ($product_tags as $tag) : ?>

<option value=”<?php echo esc_attr($tag->slug); ?>” <?php selected(isset($_GET[‘filter_tag’]) ? $_GET[‘filter_tag’] : ”, $tag->slug); ?>>

<?php echo esc_html($tag->name); ?>

</option>

<?php endforeach; ?>

</select>

</form>

Step 4: Handle the Filter Output Properly

• Keep the selected tag visible after reload
• Make sure the filter works with pagination
• Test it alongside any other active filters on the page

Step 5: Test Everything on the Front End

• Open the shop or category page
• Select different tags and confirm the right products appear
• Test on desktop and mobile
• Recheck the filter after theme or WooCommerce updates

Which Method Fits Best

Store setup, maintenance comfort, and filter behavior usually decide which path makes more sense. One option keeps things easier for day-to-day use, while the other gives deeper control when the default setup is not enough.

Can I Combine Tag Filters With Price and Category Filters?

Yes, tag filters can be combined with other filters to make product discovery more precise. This works especially well when shoppers want to narrow products step by step instead of relying on a single filter type.

• Tag + Price: Tags can group products by theme or collection, while filter by price in WooCommerce helps shoppers stay within budget.
• Tag + Category: Categories keep shoppers inside the right product group, and tags help narrow results further by style, season, or use case.
• Tag + Price + Category: Using all three together gives shoppers a more focused path, especially in stores with broader catalogs.
• Better Product Discovery: Combined filters help reduce unrelated results and make browsing feel more relevant.
• Useful for Exploratory Shopping: Shoppers who are still comparing options can narrow products gradually without feeling boxed in too early.
• Stronger Front-End Experience: When filters are arranged clearly, combining them makes the shop page feel more usable and more efficient.

How to Keep Tag Filters SEO-Friendly and User-Friendly?

Tag filters work best when they help shoppers explore products without creating extra clutter. Clean tag structure, clearer naming, and better filter control can improve usability while keeping low-value filter pages from causing SEO issues.

• Use Tags Selectively: Not every product label needs to become a tag. Keep tags focused on themes, styles, occasions, or collections that actually help shoppers explore related products.
• Avoid Thin or Repetitive Tag Combinations: Too many overlapping tags can create weak filter paths and confusing browsing choices. Try to avoid tag structures that say nearly the same thing in slightly different ways.
• Keep Important Pages Separate From Filter States: Main shop, category, and product pages should stay the stronger SEO targets. Tag-filtered views are usually more useful for navigation than for indexing.
• Keep Tag Names Clear for Shoppers: Simple and recognizable tag names make filtering easier to understand. If shoppers cannot quickly tell what a tag means, they are less likely to use it.
• Do Not Overload the Filter Area: A long list of tags can make the filter harder to scan, especially on mobile. Focus on the tags that improve discovery instead of showing every possible option.
• Make Combined Filters Easy to Read: If shoppers use tags with category, price, or other filters, the active selections should stay visible. That makes the browsing path easier to follow and easier to reset when needed.

Common Problems When Adding Tag Filters (And How to Fix Them)

Tag filters can improve product discovery, but setup issues often make them less useful than expected. Missing tags, poor placement, inconsistent naming, or weak filter behavior can all get in the way. Even with WooCommerce product filter plugins, the result still depends on how well tags are organized and how clearly the filter works on the front end.

Filter Shows but Returns Weak Results

Check whether products actually have the right tags assigned. A tag filter only works well when the tag structure is meaningful and used consistently.

Too Many Tags Make the Filter Hard to Use

Trim the list down to tags that actually help shoppers discover products by theme, occasion, style, or collection. Remove vague, duplicate, or low-value tags that add clutter without adding value.

Tag Names Feel Confusing or Repetitive

Standardize naming so similar products use the same tag language. Clear and consistent tags make the filter easier to scan and easier for shoppers to trust.

Filter Placement Gets Ignored by Shoppers

Move the filter to a more visible area on the shop or category page so it feels like part of the browsing flow rather than something users have to hunt for.

Filter Works Poorly on Mobile

Keep the tag list compact, use collapsible layouts when needed, and make sure shoppers can tap, view, and clear tags without the screen feeling crowded.

Combined Filters Become Hard to Follow

Show active selections clearly so shoppers can understand what is narrowing the results and remove filters without resetting everything.

Filtered Tag URLs Create SEO Clutter

Keep main product and category pages as the stronger index targets, and avoid letting low-value tag filter states turn into searchable pages.

FAQs About WooCommerce Tag Filters

Once tag filters are in place, the next questions usually come down to how they behave in real shopping situations. Store owners often want to know when tags add value, where they fit beside other filters, and how far they should be used across the catalog. These FAQs cover the practical side of tag filtering without repeating the setup steps.

Can Tag Filters Help With Curated Product Collections?

Yes, they can work well for curated collections. Tags are useful when you want to group products around ideas like gift picks, seasonal edits, trending items, or campaign-based selections that do not fit neatly into one category.

Are Tag Filters Better for Browsing or for Precise Filtering?

They are usually better for browsing. Tags help shoppers explore related products by theme, style, or use case, while more precise filtering often comes from things like price, size, color, or stock status.

Should I Use the Same Tags Across Multiple Categories?

Yes, when the tag has the same meaning across those categories. Doing that can make discovery more consistent and help shoppers find related products without being limited by the store’s category structure.

Can Tag Filters Support Merchandising Goals?

Yes. They can help highlight products tied to promotions, seasonal campaigns, new arrivals, or special collections. That makes them useful not just for navigation, but also for guiding shopper attention.

Do Tag Filters Make Sense for Niche Stores?

Sometimes, but not always. A niche store with a very small catalog may not need them, while a niche store with layered styles, occasions, or collection-based shopping can still benefit from tag filtering.

How Often Should Product Tags Be Reviewed?

It is a good idea to review them regularly as the catalog grows. Tags can become messy over time, especially when new collections, campaigns, or product types are added without a clear tagging standard.

Final Thoughts

Product discovery gets easier when shoppers can narrow products by theme, collection, or use case instead of relying only on categories. That is really how to add filter by tags in WooCommerce comes down to: giving visitors a more flexible way to explore related items across the store.

For most stores, a plugin-based setup is the easiest path, while custom code makes more sense when deeper control is needed. What matters most is keeping tags clear, useful, and consistent so the filter improves browsing instead of making it harder.
