Ecommerce search is one of the most important but overlooked areas of ecommerce optimisation.

As product catalogues grow and customer expectations increase, onsite search becomes increasingly important for helping users find products quickly and reducing friction throughout the buying journey.

Many retailers focus heavily on:

  • SEO
  • paid advertising
  • email marketing
  • frontend redesigns

while customers still struggle with poor search relevance, confusing filtering and weak product discovery once they arrive onsite.

Strong ecommerce search functionality can significantly improve:

  • conversion rates
  • average order values
  • customer experience
  • product discovery
  • engagement across large catalogues

However, good ecommerce search is rarely achieved simply by installing a new search platform.

Having worked across a range of ecommerce search implementations on both Shopify and Magento stores, this guide covers some of the most important ecommerce search best practices retailers should focus on operationally.

Prioritise Search Relevance

Search relevance is the foundation of a strong ecommerce search experience.

Customers expect search results to feel intelligent and relevant, even when:

  • queries contain spelling mistakes
  • wording is inconsistent
  • search terms are incomplete
  • customers use natural language

Modern ecommerce search platforms use:

  • typo tolerance
  • behavioural ranking
  • AI-driven relevance
  • natural language processing
  • synonym matching

to improve product discovery.

However, search relevance still depends heavily on product data quality.

Even advanced ecommerce search platforms struggle when:

  • product titles are inconsistent
  • attributes are poorly structured
  • categories are unclear
  • filters are incomplete

Retailers often underestimate how much catalogue management influences ecommerce search performance long-term.

Improve Filtering and Faceted Navigation

Filtering is just as important as search itself, particularly on larger ecommerce stores.

Poor filtering creates friction and makes product discovery significantly more difficult, especially on mobile devices.

Strong filtering should help customers narrow products down quickly using:

  • size
  • colour
  • price
  • brand
  • material
  • compatibility
  • category-specific attributes

Filtering also needs to remain commercially sensible.

Too many filters can overwhelm users, while inconsistent filtering structures can create confusing user experiences across categories.

For larger catalogues, filtering strategy often overlaps closely with wider ecommerce conversion rate optimisation and frontend UX improvements.

Customers increasingly expect immediate feedback while searching.

Autocomplete and instant search functionality help users:

  • refine queries quickly
  • discover products faster
  • reduce search friction
  • avoid zero-result searches

Well implemented autocomplete can also:

  • surface categories
  • suggest brands
  • promote products
  • improve product discovery
  • reduce navigation complexity

For stores with larger catalogues, autocomplete often becomes one of the most heavily used ecommerce search features.

Mobile ecommerce search behaviour differs significantly from desktop.

Customers are:

  • typing less accurately
  • searching more quickly
  • relying more heavily on autocomplete
  • navigating smaller screens

This makes:

  • filtering usability
  • autocomplete quality
  • search speed
  • result relevance

particularly important on mobile devices.

Retailers often focus heavily on desktop search experiences while mobile product discovery remains unnecessarily difficult.

Reduce Zero-Result Searches

Zero-result searches are one of the clearest indicators of search friction.

Customers reaching dead ends within onsite search often:

  • abandon the session
  • return to Google
  • leave the website entirely

Modern ecommerce search platforms can reduce zero-result searches through:

  • synonym handling
  • typo correction
  • AI-driven relevance
  • broader matching logic
  • merchandising rules

Retailers should also regularly monitor:

  • failed search terms
  • misspellings
  • high-volume zero-result queries
  • catalogue gaps

These insights often highlight wider merchandising and product discovery opportunities.

Prioritise Search Speed

Search performance matters.

Customers expect search results and filtering interactions to feel instant, particularly on mobile devices.

Slow search responses create friction and negatively affect:

  • user experience
  • engagement
  • conversion rates
  • product discovery

This becomes particularly important for larger Shopify and Magento development projects with complex catalogues and layered navigation structures.

Search performance should be considered alongside:

  • frontend optimisation
  • catalogue structure
  • indexing strategy
  • infrastructure performance

rather than purely as a standalone feature.

Use Merchandising Strategically

One of the biggest ecommerce search misconceptions is that search should operate entirely automatically.

In reality, merchandising plays a major role in delivering commercially effective search experiences.

Retailers often need the ability to:

  • boost products
  • prioritise stock availability
  • promote seasonal items
  • influence rankings
  • prioritise higher margin products
  • improve category visibility

AI-driven ecommerce search platforms can support merchandising automation, but strong commercial oversight still matters significantly.

Search optimisation is rarely purely technical.

Analyse Search Behaviour

Search analytics provide some of the most commercially valuable insights within ecommerce.

Understanding:

  • what customers search for
  • which searches convert
  • where users struggle
  • which filters are heavily used
  • where customers abandon sessions

can reveal:

  • catalogue weaknesses
  • navigation problems
  • merchandising opportunities
  • missing products
  • content gaps

Retailers often sit on valuable search data without using it operationally.

Keep Product Data Clean

Strong ecommerce search depends heavily on strong product data.

Search platforms generally perform best when:

  • product titles are consistent
  • attributes are structured properly
  • categories are logical
  • filtering is maintained carefully
  • metadata is accurate

Poor product data often causes:

  • weak relevance
  • poor filtering
  • inconsistent autocomplete
  • low-quality recommendations

Even AI-powered ecommerce search platforms cannot fully compensate for inconsistent catalogue management.

Choose the Right Ecommerce Search Platform

Different ecommerce search platforms suit different operational requirements.

For example:

  • Algolia is often well suited to highly customised ecommerce experiences
  • Klevu focuses heavily on AI-driven merchandising and search relevance
  • Nosto combines personalisation with product discovery
  • Mirasvit offers cost-effective Magento-focused search functionality

I’ve also covered:

The right solution depends heavily on:

  • catalogue complexity
  • platform requirements
  • merchandising needs
  • technical capability
  • operational maturity

Final Thoughts

Strong ecommerce search functionality can significantly improve product discovery, conversion rates and customer experience across both Shopify and Magento stores.

However, successful ecommerce search optimisation depends on much more than software selection alone.

The strongest ecommerce search experiences are usually built around:

  • clean product data
  • strong filtering
  • effective merchandising
  • fast performance
  • thoughtful UX
  • ongoing optimisation

Retailers often focus heavily on frontend design and acquisition channels while overlooking the operational impact of onsite search and product discovery.
