Clustering for
Market Segmentation
Presentation by Mike Calder
Clustering
• Used for market segmentation
– Researchers want to find groups that can be
targeted with the same marketing strategy
• Given data of which users click on certain
adds, derive discriminative clusters
Strategy seen in use for almost 2 decades!
2
Motivation
• Marketing companies want to produce as
few ads as possible while tailoring to the
largest possible audiences
• Search engines already collect enough
statistics to make these derivations
– No extra methods needed to obtain data
3
Sample Click Data from Yahoo!
Taken from (Haider, 2012)
Represents the volume of advertisement clicks
on Yahoo! (different colors indicate categories)
4
How Can We Use The Data?
• Sample Data Attributes
– Time advertisement was clicked on
– Location of the click on the page
– Category the advertisement falls into
– Type of marketing strategy used in the ad
• Must decide on a clustering algorithm and
a number of clusters to use
5
Clustering Method Options
• Algorithms
– K-means
– Hierarchal
– Centroid-based
– Distribution-based
– Novel combinations of the above
• Attempting to maximize “log-likelihood”.
6
Sample Algorithm Testing
Taken from (Haider, 2012)
Novel algorithm details are described in
