The State of E-Commerce Search: An Evaluation of UK Top Retailers’ Websites

An Analysis of the Top 10 E-Commerce Search Features & Functionalities

According to Econsultancy, while only 30% of e-commerce visitors use site search, conversion rates through site search can be up to 50% higher than the average. But even the top-tiered e-commerce websites can fail to provide the most optimised search experience for online shoppers.

To learn about the overall trends of how site search features are performing on UK e-commerce websites, Search Technologies’ technical architects conducted research to evaluate a sample of 70 websites from InternetRetailing’s list of UK Top 500 E-Commerce Sites. The full report with our findings and best practice examples can be downloaded here.

For this evaluation, our experts analysed the top 10 key e-commerce site search features. Using our search quality analysis methodology, they scored the features based on whether they were present and how well they performed on each of the 70 sample websites.

Below are the site search features and functionalities evaluated. Our experts also provided recommendations on how these features and functionalities can be achieved.


  • “Did you mean?” 
  • Synonyms 
  • Stemming 
  • Hyphenation
  • Type-ahead 
  • Searchable categories 
  • Searchable descriptions
  • Product code search
  • Offensive language filter 
  • Query response time 


From our experience delivering e-commerce search solutions to global customers, these features and functionalities are the minimum requirements for good e-commerce search. Once they are implemented and well-tuned, e-tailers aspiring to become leaders can start defining their roadmaps for achieving more innovative features. An example of such roadmap is Search Technologies’ E-Commerce Scorecard, which is discussed in detail in our report.
