Choosing an e-commerce search platform means more than helping buyers in finding items to buy. Selecting this platform should also mean finding out what the shopper intends to find, and personalizing his shopping experience with the goal of turning passive searching into active buying.
This is the purpose of Fast Simon. The company offers a combination of AI based search, efficient product recommendations, personalization of the user experience and merchandising tools.
But is it worth the money spent? What are the nuances of purchasing Fast Simon? And can you find better alternatives to Fast Simon to ensure more efficient search?
What Is Fast Simon?
Fast Simon is a product discovery platform for e-commerce that provides consumers with useful products using advanced search capabilities, personalization, and excellent collection pages.
Fast Simon was known as InstantSearch+, but later became more than just a search solution.
The primary users of Fast Simon are:
- Shopify and Shopify Plus merchants
- Medium, as well as larger, online stores
- Retailers with extensive product inventories
- Companies desiring to enhance their recommendations.
Fast Simon’s position today revolves around Commerce-Native AI combining data on shopping behaviors, product information, stock availability, pricing, and merchandising.
What Makes Fast Simon Stand Out? Key Features
Fast Simon offers several capabilities that extend beyond a conventional search bar.
1. AI-powered site search
With the help of its AI-search feature, shoppers can locate products through simple natural language queries, through the use of autocomplete, and even correcting typos. For instance, rather than being directed solely by keyword matches, a shopper searching for “comfortable black running shoes” will receive appropriate matches.
2. Personalized product recommendations
Fast Simon uses shopper behavior to personalize suggestions of products for each customer. It can show recommendations across search pages, collections, and product pages.
3. AI merchandising
Both merchants and AI solutions can influence product search. Merchants are able to control catalog content while AI optimization can facilitate processes by interacting with applied methods.
4. Visual search and discovery
Fast Simon offers visual detection functionalities like product resemblance, visual searching, and Shop the Look. These functionalities are beneficial for firms in the fashion, décor, cosmetics, and lifestyle sectors where pictures play a part in influencing buyers’ decisions.
5. Search analytics and A/B testing
Analyzing the data assists retailers in tracking browsing activities, shoppers patterns, and performance of discovery. A/B testing enables teams to consider different strategies and see the effects they produce.
How Does Fast Simon Work?
Fast Simon works with an e-commerce website that shares its product catalog with the solution, which includes product attributes, pricing, and availability.
When a customer writes a query, the system processes the input in order to provide results based on product data, relevance factors, and personalization options available.
