eCommerce Faceted Search: Implementation & Best Practices

As you may already know, there are tens of millions of eCommerce websites around the world. Plus, the eCommerce statistics are going off the charts. So if you want to stand out, one of the key things you need to ensure is a seamless customer experience. To that end, faceted search can be a powerful, helpful tool.

With faceted search, the users can refine their search results based on specific attributes or facets. That means the results will be more focused on what they are looking for.

So how do you implement eCommerce faceted search? Well, our eCommerce developers have helped me compile this blog to show how it’s done. First, though, let’s see what faceted search is.

What is Faceted Search?

Faceted search is a type of search functionality that allows users to refine their search results based on specific criteria or attributes. It’s often used in eCommerce websites and databases to help users quickly narrow down their options and find the exact products or information they’re looking for.

Imagine you’re shopping for a new pair of shoes. Instead of typing “shoes” into a search bar and getting a vast list of results, faceted search might allow you to filter by:

• Color: Red, blue, black, etc.
• Size: Men’s, women’s, kids’
• Style: Sneakers, sandals, boots
• Brand: Nike, Adidas, Converse, etc.
• Price: Under $50, $50-$100, over $100

With these filters (or “facets”) and more, you can quickly and easily find the specific shoes that meet your needs.

Benefits of eCommerce Faceted Search

Faceted search goes beyond traditional search bars by providing a dynamic filtering system. It allows the shoppers to refine their search based on specific criteria. The benefits of this feature are enjoyed by both the eCommerce businesses and customers.

How to Implement eCommerce Faceted Search?

Integrating the faceted search feature in your eCommerce website involves identifying the facets, creating a robust indexing system, and developing a user-friendly interface. Here’s how this process unfolds.

Step 1: Identify Relevant Facets

First and foremost, you need to identify the right facets per your eCommerce website (and the products). It’s crucial for the success of your eCommerce faceted search implementation. These facets act as filters that help customers narrow down their search results and find the exact products they’re looking for.

Key Attributes for Faceted Search in eCommerce

• Core attributes: Consider fundamental product characteristics like color, size, brand, price, and material.
• Specific attributes: Depending on your product category, you might need more specific facets, such as style, material, or features.
• Hierarchical attributes: For products with multiple levels of categorization (e.g., clothing with categories like tops, bottoms, and dresses), consider hierarchical facets to allow for more granular filtering.

You can define more attributes through customer surveys and competitor research. Learn from their approach and incorporate effective facets into your own implementation.

Step 2: Create a Robust Indexing System

A robust indexing system is essential for providing fast and accurate search results in eCommerce faceted search. This system efficiently stores and organizes product data, making it easily searchable based on various facets.

Let’s take a look at the key considerations for indexing systems.

Indexing Technology

• Database: Relational databases like MySQL or PostgreSQL can be used for smaller datasets.
• Search Engines: Elasticsearch or Solr are popular choices for handling large-scale indexing and search operations.
• Specialized eCommerce Platforms: Many eCommerce platforms have built-in indexing capabilities.

Indexing Frequency

• Real-time indexing: For dynamic product catalogs, consider real-time indexing to ensure that new products or changes to existing products are immediately searchable.
• Batch indexing: For less frequent updates, batch indexing can be more efficient.

Indexing Depth

• Full-text indexing: Index the entire product description for more comprehensive search results.
• Attribute-based indexing: Index specific attributes like color, size, and brand for faster filtering.

Data Quality

• Ensure data consistency: Maintain data integrity to avoid inconsistencies in search results.
• Handle synonyms and variations: Consider techniques like stemming and lemmatization to handle different variations of the same word.

Scalability

• Design for growth: Your indexing system should be able to handle increasing amounts of data as your product catalog expands.
• Consider distributed systems: For very large datasets, distributed indexing systems can improve scalability and performance.

Performance Optimization

• Caching: Implement caching mechanisms to store frequently accessed data in memory for faster retrieval.
• Query optimization: Optimize your search queries to improve performance and reduce load on the indexing system.
• Hardware considerations: Ensure that your hardware resources (CPU, memory, storage) are sufficient for your indexing needs.

Make sure you work on these factors carefully. They will help you create a fast, accurate, and scalable indexing system for your eCommerce faceted search.

Step 3: Develop a User-friendly Interface

A well-designed user interface (UI) is crucial for making your eCommerce faceted search effective and easy to use. Here are some key considerations:

Facet Placement and Organization

• Prominent placement: Facets should be easily visible and accessible to users.
• Logical grouping: Group similar facets together to improve usability.
• Clear labeling: Use clear and concise labels for each facet.

Facet Interaction

• Intuitive controls: Implement easy-to-use controls like checkboxes, radio buttons, or sliders.
• Dynamic updates: Update search results in real-time as users apply or remove facets.
• “Clear all” functionality: Provide a way for users to quickly reset all filters.

Visual Cues

• Highlight selected facets: Use visual cues like color changes or check marks to indicate selected facets.
• Show facet counts: Display the number of products that match each facet to help users make informed choices.
• Provide a “results summary”: Show a summary of the current filters applied and the total number of results.

Mobile Optimization

• Responsive design: Ensure that your faceted search interface adapts well to different screen sizes.
• Touch-friendly controls: Use larger buttons and touch-optimized elements for mobile devices.
• Consider mobile-specific features: Explore features like autocomplete and predictive search to enhance the mobile experience.

Also, try different arrangements of facets and controls through A/B testing to find the most effective design. The ultimate goal needs to be user-friendliness.

Step 4: Consider Mobile Optimization

As you may already know, a majority of the eCommerce website traffic comes from mobile devices. So it’s very important you optimize the faceted search feature for mobile usability. Here’s what you need to consider.

Responsive Design

• Fluid layouts: Design your interface to adapt seamlessly to different screen sizes and orientations.
• Touch-friendly elements: Use larger buttons and touch-optimized controls for easy interaction.
• Minimalist design: Keep your interface clean and uncluttered to avoid overwhelming mobile users.

Facet Placement and Organization

• Vertical scrolling: Consider a vertical layout for facets to minimize scrolling.
• Accordion-style menus: Use collapsible menus to save space and avoid overwhelming users.
• Prioritize essential facets: Place the most important facets at the top of the list for easy access.

Search Bar Optimization

• Autocomplete suggestions: Provide autocomplete suggestions to help users find products quickly.
• Voice search: If your platform supports it, enable voice search for a more convenient experience.
• Clear search button: Ensure that the search button is easily visible and accessible.

Performance Optimization

• Minimize load times: Optimize images and reduce the number of HTTP requests to improve page load speed.
• Leverage caching: Implement caching mechanisms to store frequently accessed data and reduce server load.
• Compress assets: Use compression techniques to reduce the size of your website’s files.

User Experience Considerations

• Intuitive navigation: Make it easy for users to navigate between facets and search results.
• Clear information: Provide clear and concise information about each facet and its options.
• Error handling: Implement robust error handling to prevent frustrating experiences for users.

After taking care of these considerations, test the feature on different devices and ensure the customers have a seamless experience.

Step 5: Integrate Third-party Plugins or Extensions

Third-party plugins and extensions can be a valuable tool for implementing faceted search in your eCommerce store. That is especially useful if you’re using a popular platform like WooCommerce, Magento, or Shopify. These plugins often offer pre-built functionality and can save you time and effort in developing custom solutions.

Here’s what you need to consider:

• Platform Compatibility: Ensure that the plugin or extension is compatible with your eCommerce platform.
• Features and Functionality: Evaluate the features offered by the plugin or extension to ensure it meets your specific requirements.
• Ease of Use: Look for plugins or extensions with a user-friendly interface and clear documentation. Consider the complexity of the installation and configuration process.
• Performance: Assess the plugin or extension’s impact on your website’s performance. Look for plugins that are optimized for speed and efficiency.
• Cost: Consider the pricing model of the plugin or extension, including any recurring fees or subscription costs.

For example, if you are using WooCommerce (with WordPress) for your eCommerce website, a plugin like FacetWP will be helpful. There are several other plugins and extensions available, but you need to choose carefully. Like Mirasvit Advanced Search (for Magento) and Klevu Search (for Shopify) among others.

Step 6: Test & Iterate

Testing and iteration are essential steps in ensuring the effectiveness of your faceted search implementation. By continuously evaluating and refining your search functionality, you can optimize the user experience and drive better results.
