The Importance of In-App Search for eCommerce

Optimizing your website for mobile responsiveness has become a well-established practice. But, considering that 72% of users find mobile shopping easier on an app, it’s increasingly important to create a dedicated app for your store, too.

Your customers will be more inclined to open and shop on your app if it's easy to use. That starts with the search bar.

A powerful search can:

  • Facilitate quick, relevant discovery: No one wants to endlessly scroll or browse categories. A great search function lets them find what they need quickly and efficiently.
  • Provide product suggestions: An effective search can do more than just find products. It can suggest related products, recommend alternatives based on personalized browsing history, and even predict what customers might like.
  • Enhance conversion rates: Optimized search makes it easier for users to make purchases, thereby improving conversion rates.

Take a look at fashion boutique That's So Fetch. With a mobile-first mentality, it integrated a highly functional search into its app experience, making products and collections easy to find.

How to Add Search to Your Mobile App

Adding a Search Bar Manually

Manually adding search functionality to a mobile app involves several technical steps and often requires development expertise.

  1. The process begins with creating a database to store searchable content.
  2. You then need to implement a search algorithm to index and search the content in the database.
  3. Add a user interface element, such as a search bar, to enter their search queries.
  4. Connect the search bar to the search algorithm.
  5. Finally, test to ensure it works properly.

If you have the expertise and resources, doing this yourself means you have more control over the user experience. However, it's often challenging and time-consuming to develop a robust and efficient search function.

Some common challenges associated with implementing a search function in mobile apps are data quality, performance, and scalability. You can mitigate these by doing the following:

  • Use data cleaning and validation procedures and regularly update the data to ensure that it is accurate and up-to-date.
  • Use efficient algorithms and data structures.
  • Use a distributed search architecture and by caching frequently accessed data.

While it's possible to build the search function on your own, there are helpful apps that can make the process seamless. Let's take a look at those.

Thankfully, third-party apps are more efficient and cost-effective than web development. This is great for businesses that don't want to deal with the technical resources required. These solutions often come with advanced features and are regularly updated and maintained by the provider.

For eCommerce apps like Princess Polly, a quick and efficient search function is key for user experience. Yet, it’s technically challenging to develop and maintain. To solve this problem, the fashion brand opted for the Fast Simon x Tapcart integration.

Focus on consistent optimization and user experience enhancement to maintain successful search functionality. Here's how to optimize:

  • Auto-complete: Implement optimized auto-complete to help users quickly enter their search queries.
  • Synonyms and misspellings: Account for synonyms and misspellings. This way users can find products even if they make a mistake in their search queries.
  • Filters: Use optimized filters by category, price, brand, and other criteria, refining search results for users.
  • Visual search: Consider implementing visual search, allowing users to search for products by uploading a photo or taking a picture, adding a unique dimension to the search experience.

Continuously Testing for Mobile App Search Effectiveness

To ensure that your mobile search app continues to achieve success, it is important to implement and maintain continuous optimization practices. These practices can help you identify and address any issues or areas of improvement and keep up with changing market trends and user needs.

  • Monitoring KPIs: Critical metrics like click-through, conversion, and bounce rates indicate overall search effectiveness. Regularly monitoring these metrics prompts investigation and improvement initiatives.
  • A/B testing variations: Experiment with variations on elements like result rankings, filter mechanics, and search suggestions to enhance user experiences.
  • Collecting user feedback: Gather insights through interviews, surveys, and reviews to identify search friction and guide future enhancements.
  • Actioning recommendations: Rapidly address feedback through search algorithm updates and new features, building long-term loyalty by showing customers their input matters.
