How to optimize faceted search for mobile and tablet devices in WordPress and WooCommerce

Introduction

Faceted search is a powerful feature that allows users to narrow down their search results by applying multiple filters or facets. This functionality is especially crucial for e-commerce websites that provide a variety of products. However, optimizing faceted search for mobile and tablet devices can be a challenge due to limited screen space and slower performance. In this post, we will discuss how to optimize faceted search for mobile and tablet devices in WordPress and WooCommerce, along with relevant code examples.

Optimizing Faceted Search for Mobile and Tablet Devices

Faceted search optimization for mobile and tablet devices involves optimizing both the front-end and back-end of your website. Here are some best practices to consider:

1. Minimize the number of facets

On mobile devices, it’s crucial to prioritize usability and simplicity. Limit the number of facets displayed by default to prevent overwhelming the user. Consider data analysis to determine which facets are the most relevant and display them accordingly.

2. Collapse and expand facets

To save space, use collapsible facet menus that can be expanded or collapsed by the user. This allows them to choose specific facets without cluttering the screen with too much information. This can be achieved using JavaScript or CSS animations.

3. Responsive design

Ensure that your website’s design is responsive and adapts to various screen sizes. This includes making sure that the faceted search interface is displayed properly on smaller screens, such as tablets and mobile phones.

4. Lazy loading

To improve performance and page load speed, implement lazy loading for facet values. This means loading facet values dynamically as the user scrolls, instead of loading all values upfront. This technique reduces the initial page load time and improves the overall user experience.

Code Examples

PHP Client (Embedded in HTML tags):

To implement facets in WordPress and WooCommerce, you can use the WooCommerce REST API in conjunction with custom queries. Here’s an example of a PHP client script to retrieve product facets:


$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_URL => 'https://yourdomain/wp-json/wc/v3/products/facets',
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => '',
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 0,
  CURLOPT_FOLLOWLOCATION => true,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => 'GET',
  CURLOPT_HTTPHEADER => array(
    'Authorization: Bearer your_token_here'
  ),
));

$response = curl_exec($curl);

curl_close($curl);

echo $response;

JavaScript Client (Embedded in HTML tags):

To enhance user interaction on mobile and tablet devices, you can use JavaScript to dynamically update facets. Here’s an example of a JavaScript client script to update facets based on user selections:


function updateFacets() {
  // Retrieve selected facet values from user interaction
  const selectedFacets = getSelectedFacets();

  // Make an AJAX request to retrieve updated facet values
  const xhr = new XMLHttpRequest();
  xhr.open('POST', 'https://yourdomain/wp-admin/admin-ajax.php', true);
  xhr.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded; charset=UTF-8');
  xhr.onload = function () {
    if (xhr.status >= 200 && xhr.status < 400) {
      const response = JSON.parse(xhr.responseText);

      // Render updated facets on the page
      renderFacets(response.facets);
    }
  };
  xhr.send('action=update_facets&selected_facets=' + encodeURIComponent(selectedFacets));
}
