What Is Head/Tail Analysis?

Head and Tail analysis corrects misspelling, strange word orders, or other mistakes users make when they search.

Here’s a quick explainer on how head tail analysis and AI can fix searches to help users find what they need.

‘How They Search’ Is as Important as ‘What They Search’

No one searches the same way. To optimize your site, get a handle on where people are getting frustrated, and find out what terms they use  — you’ll need head/tail analysis to do a thorough query analysis.

Head Tail Query Graphic

Head queries make up the largest volume of queries and tend to be short words or phrases. Tail queries are a higher volume of fewer queries that tend to be longer words or multi-word phrases. The torso is everything else in between.

Why Worry About the Tail?

Many believe you only need to worry about the popular head queries. But head queries tend to be more topical in nature — and may represent only a small fraction of the total search queries on your site or application.

Tail queries, on the other hand, may mean missed opportunities. It could mean a typo, a number not typed correctly, or even a synonym.

How Much Opportunity Are You Missing?

Lucidworks Fusion runs offline head/tail analysis on all your queries and classifies tail distribution.

So you can see what you are missing – and fix it.

Use Head/Tail Analysis to Increase Engagement

Log File Analysis

You could spend your days digging through log files to see all the queries used. Or you could use Head/Tail Analysis to see why Tail queries are forming.

Head/Tail Analysis Relies on User Signals

Looking at only the query analysis is only half the job. Lucidworks Fusion ingests users’ behaviors too: what they clicked on, what they didn’t, and what they rewrote. We feed these signals into Fusion to find synonyms, misspellings, and more popular “head” queries. For example, if users frequently type “manger” and “manager” in succession If “carpet” typically follows “rug” Fusion learns those are synonyms.

Head/Tail Analysis allows us to look at historical behavior and rewrite the query for greater relevance.
