WooCommerce’s default product search is a significant conversion problem for stores with more than a few hundred products. It searches product titles and descriptions but misses SKUs, product attributes (colour, size, material), product tags, and variation data. A customer searching for “navy blue large” expecting to find a shirt in that colour and size finds nothing because those attributes are stored as structured data, not in the product description. Fixing this requires replacing or extending the default WooCommerce search.
Why WooCommerce Search Fails
WooCommerce products store most of their meaningful data as post meta (attributes, variations, SKU, dimensions, weight) rather than in the post title or content. WordPress’s default search only queries the wp_posts table for post_title and post_content. All the structured product data in wp_postmeta is invisible to the default search.
This means a store with 500 products might only have a dozen words in each product title and a short description – everything else that distinguishes products from each other (the attributes, the SKU, the tags) is unreachable through search. Customers who know exactly what they want and search for it precisely find nothing, then leave.
Option 1: SearchWP with WooCommerce Extension
SearchWP with its free WooCommerce Integration extension provides the most complete product search improvement. Configure it to index SKU, all product attributes, short description, long description, and product tags with appropriate weights. A search for a specific SKU returns that product at the top; a search for an attribute value returns all products with that attribute.
SearchWP also indexes product variation data – a variable shirt with three colour variations can be found by searching any of those colours even if the main product title does not mention them. This is particularly valuable for clothing, accessories, and configurable products.

Option 2: Relevanssi with Custom Field Configuration
Relevanssi free provides significant improvement over default WooCommerce search when configured to index relevant product meta keys. Add the WooCommerce meta keys to Relevanssi’s custom field indexing: _sku for product codes, and the attribute meta keys (pa_color, pa_size, etc. – the actual keys used in wp_postmeta for WooCommerce attributes). This is free and covers most product search needs.
Relevanssi’s limitation for WooCommerce is that it indexes the stored meta values (taxonomy term IDs for attributes) rather than the readable term names. SearchWP’s WooCommerce integration specifically handles this by indexing term names rather than IDs, making attribute search more reliable.
Option 3: Dedicated WooCommerce Search Plugins
WooCommerce-specific search plugins like FiboSearch or YITH WooCommerce Ajax Search focus entirely on product search UX – live search dropdowns showing product images, prices, and links as customers type. These plugins typically use WooCommerce’s existing product data more effectively than the default search but are less configurable for custom indexing than SearchWP or Relevanssi.
Live Search for Better Conversion
Regardless of which backend search plugin you use, adding a live search interface (as-you-type suggestions in a dropdown) significantly improves product discoverability. Customers see product thumbnails, names, and prices as they type – often clicking a suggestion before completing their full search query. This is how major ecommerce platforms (Amazon, ASOS, Shopify stores) handle product search, and it outperforms the traditional “type query, hit enter, browse results” flow for most customers.
