Criticisms and New Criterion for Steps of Marketing Segmentation
Like every subject, Marketing Segmentation has its limits and criticisms that it faces. People generally argue that geographic/demographic segmentation can be overly descriptive and provides insufficient insights to convey communication strategies. Another aspect that we can think of is, difficulties with market dynamics, and instability of segments over time.
Furthermore, according to Daniel Yankelovich (2006), traditional demographic traits such as age, sex, education, and SES levels are no longer enough to considered as basis for marketing strategies. Next, nondemographic traits(values, preferences and tastes) seem to have more influence over consumers’ purchases rather than demographic traits, and lastly, sound marketing strategy depended on identifying segments the were potentially receptive to a particular brand and product category.
Uses of Marketing Segmentation in eCommerce
Thanks to today’s technology, we can surpass the criticisms provided by Yankelovich (2006) with AI powered personalization and data-driven insights about customers. It is a game changing technology that helps to satisfy each and every customer’s needs just by making sense of their actions online. AI powered personalization eliminates manually created segments and take the game up to a whole new level.
With the help of an eCommerce personalization software, tracking an online shopper’s behaviour in real time and making the best of this data is possible. Rather than solely depending on the static demographic data, the dynamically changing purchase intentions of an online visitor can be sorted out and used to predict the next purchase. This in turn is translated into higher sales, higher conversions and customer loyalty.
