e. Commerce Technology 20 -751 Lecture 10: Mass Personalization
Personalization • “Real world”: humans conduct the customer relationship • Web: Too many users, too few humans, too little time – Answer: mediate the relationship by machine • How to get the necessary information? How to use it? • What is the underlying technology? • Benefit to vendor – Higher sales per visit – More return visits • Benefit to customer – Tailored, efficient web experience – Saving in time and convenience

“Real World” v. Web Personalization • In the real-world – – Too expensive (requires humans) Too intrusive (customers don’t like being watched) Too slow (capture-analyze-decide cycle inefficient) Data not centralized • On the Web – – Cheap (performed by computer) Non-intrusive (user is not aware of monitoring) Fast (real-time, while user is visiting) Data captured permanently and centrally
Web Personalization • Creates “relationship” – Human tendency to show loyalty to the familiar (Mc. Kinsey) • Stickiness – Tendency of customers to return – Tendency to stay longer (“shelf space in the brain”) • Competitive necessity • Effective use of customers’ time • Increased “cleverness” + convenience
Empowering the User • Users have tremendous leverage on the Web – Leave your site freely – Compare prices cheaply – Exchange information quickly – Gómez. com, epinions. com • How can business recover the advantage? – Personalize! If everyone is treated differently, power cannot be concentrated
What is Personalization? • Addressing customers by name and remembering their preferences • Empowering the customer. Examples: Land’s End, llbean • Showing customers specific content based on who they are and their past behavior • Product tailoring. Example: dell. com • Connecting to a human being when necessary • Allowing visitors to customize a site for their specific purposes • Users are 20%-25% more likely to return to a site that they tailored (Jupiter Communications, Inc. )
The Secret: Know the User • IP address, e. g. 205. 228. 12. 204 Look it up. – Anonymous, but I might know your employer • Domain name, e. g. www. mckinsey. com – I probably know your employer • Name, address, phone no. – A good start • Social security number – I know everything 20 -751 ECOMMERCE TECHNOLOGY SUMMER 2000 COPYRIGHT © 2000 MICHAEL I.

Know Your Customer • • • Insider trades (search PNC) Inmate release (search Jones with photos) Tax records Marriage records (look up Snelling in Berks Co. ) Property assessments (look up 101 Main) Home sale prices (search zip 10471, $1. 5 -$3 million, year 2000) Phone number by address (look up 5026 Arlington Bronx) Census data (look up 5026 Arlington 10463) Altavista (search “jonathan bram”, “susan bram”) Nationwide searches Death index 20 -751 ECOMMERCE TECHNOLOGY SUMMER 2000 COPYRIGHT © 2000 MICHAEL I.
