Search Log Analysis
A practical IA and product method for understanding user intent, search failures, and findability gaps.
How to use search log analysis to uncover what users are looking for, where search is failing, and how to improve findability.
What it is

Search log analysis is useful because it shows what users are actively asking for, not just what your navigation suggests they should want.
When to use it
Use this method when glossarySearchSearch is the functionality that allows users to find content or information by entering queries. It relies on indexing, metadata, and relevance algorithms to return useful results.Open glossary term is a key part of the experience.
It is most useful when:
It is less useful when:
Search log analysis is often used alongside card sorting and tree testing to improve findability.
Key takeaway
Use search log analysis when you need direct evidence of what users are trying to find and where your structure is falling short.
How to run it
Set up properly
Be clear on what is actually being logged before you analyse anything: the query, the results returned, what was clicked, and what happened next. Query volume without outcomes tells you what people asked, not whether they were answered.
Make sure failed glossarySearchSearch is the functionality that allows users to find content or information by entering queries. It relies on indexing, metadata, and relevance algorithms to return useful results.Open glossary term are captured. Most analytics setups record what succeeded and quietly discard the zero-result queries, which are the ones you needed.
