eCommerce search platforms have evolved substantially over the last 30 years. In the 1990s, they were simple tools that only displayed results based on keyword matching, and if the user made a typographical error, the tool would return no results.
As of today, 2024, these search engines are capable of understanding when a user makes a typographical error, recommending search terms, recognizing synonyms, and even analyzing user behavior to display products according to their interests.
Major platforms like Amazon, Mercado Libre, and Netflix have raised the bar for what a good search experience should be like. Today, users expect search to be just as simple, intuitive, and fast as it is on these platforms. This puts pressure on companies that want to optimize the search engine for their eCommerce site.
Search has become a relevant topic in online stores, both to improve user experience and to increase sales, which has led more and more companies to establish their own departments exclusively dedicated to improving search results.
Below, we will present the evolution of search in eCommerce and the trends your company needs to adapt to.
What Is an eCommerce Search Engine?
A search engine is a functionality integrated into an eCommerce platform that allows users to find products within an online store's catalog.
Its main objective is to facilitate product search and navigation, improving the user experience and increasing the likelihood that visitors will find and purchase the items they desire.
Search engines index the product catalog to display results based on the keywords entered in the search bar.
These search engines are an essential tool that not only helps users find what they are looking for quickly and efficiently but also plays a crucial role in the commercial success of the online store by enhancing the user experience and increasing sales.
Background of Search Engines in eCommerce
eCommerce search engines have a long history that has developed in parallel with the evolution of information technology and online commerce. Here is an overview of the background of search engines in eCommerce:
1. Origin and Keyword Search
Static Catalogs: Early eCommerce sites featured static catalogs where users navigated through categories to find products. There were no sophisticated search tools.
Basic Search (1990s): The first versions of eCommerce search engines allowed users to search for products by exact keyword matches in product titles or descriptions.
Limitations: These systems were basic and had little ability to handle typographical errors, synonyms, or variations in keywords. Results were often irrelevant if exact terms weren't used.
2. Development of Search Algorithms
Advances in Algorithms (early 2000s): Search algorithms began to evolve to improve the relevance of results. Techniques such as phrase matching, proximity analysis to evaluate the distance and relationship between words to improve result accuracy, and term weighting to identify the most relevant terms for a specific query were introduced.
Semantic Search (late 2000s): Semantic search algorithms were developed to understand the context and intent behind user queries. An example of this type of search is when entering "headache," the results would directly show a remedy for this pain. This allowed for greater accuracy in search results by interpreting the meaning of words rather than just looking for exact matches.
Spell Correction and Suggestions: Features like automatic correction of typographical errors and search suggestions were added to help users find what they were looking for even if they made mistakes while typing.
3. Integration with eCommerce Platforms
Early Integration (mid-2000s): eCommerce platforms began to integrate more advanced search engines directly into their systems. This allowed online stores to offer more sophisticated and personalized search experiences.
Filters and Facets: Filters and facets were introduced, allowing users to refine their searches by various criteria such as price, category, brand, among others. This significantly improved the search experience by enabling users to find specific products more quickly and efficiently.
Visual Search (late 2010s): Image recognition technology allowed users to search for products using photos. This innovation was driven by advances in machine learning and artificial intelligence.
Voice Search: With the popularization of virtual assistants (like Siri, Alexa, and Google Assistant), voice search capabilities were introduced on eCommerce platforms, making it easier to search on mobile devices and smart homes.
4. Current and Future Trends
Predictive Recommendations (2020s): Search engines began using Artificial Intelligence (AI) and machine learning to analyze large amounts of data and offer predictive recommendations based on user behavior patterns.
Multimodal Search: The integration of multiple search modes (text, voice, visual) into a unified and seamless experience.
Omnichannel Experience: Search engines are evolving to offer a consistent and continuous search experience across multiple channels and devices. Thanks to this, you can check inventory availability in each store or filter to show only what is available in online inventory.
Conversational Search: Chatbots and virtual assistants are being used to interact with users in a conversational manner to help them find products more naturally and efficiently.
Augmented Reality and Virtual Reality: The integration of these technologies is being used to offer more immersive search and shopping experiences. In furniture stores or clothing shops, a virtual fitting room is being integrated, allowing users to try the product from home.
The evolution of eCommerce search engines has gone through several stages, from simple keyword matching engines to sophisticated semantic and personalized search systems. Integration with eCommerce platforms has been crucial to improving the relevance and accuracy of search results, providing users with more efficient and satisfying shopping experiences.
