Dr. Ehud Reiter, Computing Science, University of Aberdeen1 E-Commerce (2) l Attracting and keeping customers »Issue: security, trust l Legal issues l Personalisation l Adverts

Dr. Ehud Reiter, Computing Science, University of Aberdeen2 Customers are different! l Consumer types »Individual consumers »Organizational buyers l Goal of shopping »Pragmatic: buy something useful, cheaply »Hedonic: have fun l Personality »Impulsive buyerspurchase quickly »Patient buyersmake some comparisons first »Analytical buyersdo substantial research before buying

Dr. Ehud Reiter, Computing Science, University of Aberdeen5 Security/Trust l Security/trust »Will the company actually deliver the correct product in reasonable shape, in a reasonable time, at correct price »Will the customer pay up (is the credit card stolen, will it be repudiated) l Technical aspects (CS5401) l Focus here on trust

Dr. Ehud Reiter, Computing Science, University of Aberdeen6 Trust in physical shops l Experience: shoppers trust shops theyve used before l Appearance: shoppers trust store that look reputable l Complaints: easy to complain, shop cant hide l Transactions are simple

Dr. Ehud Reiter, Computing Science, University of Aberdeen7 On-line trust l What makes you trust an e-commerce shop?

Dr. Ehud Reiter, Computing Science, University of Aberdeen8 On-line Trust l Experience: I trust Amazon because Ive used them before »Reputation: because my friends use them »Very important with e-shops l Appearance: do I trust Amazon because they have a nice website??? »Less important than with physical shops »Marketing helps

Dr. Ehud Reiter, Computing Science, University of Aberdeen9 On-line trust l Complaints: Harder to complain since dont know where shop is l Transactions are complex because of delivery »Where many e-shops mess up l Third-party: do I trust Amazon more if another web site says good things about Amazon (???)

Dr. Ehud Reiter, Computing Science, University of Aberdeen10 Does Amazon Trust Me? l Amazon trusts me because »Experience: Ive always paid Amazon before »Reputation: Ive used other companies and always paid up »Marketing: Amazon threatens nasty things to customers who dont pay up

Dr. Ehud Reiter, Computing Science, University of Aberdeen11 Trust l We know how trust is established in physical shops. l We are developing mechanisms for establishing trust in e-shops »Partially technology, but psychology and sociology probably matter more »Lack of trust mechanisms is barrier to new e-shops

Dr. Ehud Reiter, Computing Science, University of Aberdeen12 Legal Issues: Tax l In USA, one driving force behind early e-store success was less tax »Because of a tax loophole, sales tax (VAT) was not charged on e-commerce sales l Automatically gave price advantage to e-commerce sites!

Dr. Ehud Reiter, Computing Science, University of Aberdeen13 Legal Issues: Intl E-Commerce l In theory, e-commerce means sites can sell globally l In practice, difficult because of different tax rules, regulations, customs, etc »More common to set up subsidiaries in different countries, as Amazon has done l Lack of global legal/regulatory framework hinders ecommerce

Dr. Ehud Reiter, Computing Science, University of Aberdeen14 Personalisation l E-Commerce sites can treat customers differently »Offer recommendations, special deals »Personalise web site »Adjust prices l In theory, personalised shop one of the great benefits of e-commerce

Dr. Ehud Reiter, Computing Science, University of Aberdeen15 Recommendation l Build profiles »What has X bought? »What has X looked at? »Demographics: age, gender, etc l Recommendation »Rules: If X buys Harry Potter 6, recommend HP 7 »Data Mining: Other people who bought Harry Potter also bought Lord of the Rings »Collaborative: Xs overall buying profile is similar to Y, so recommend whatever Y bought

Dr. Ehud Reiter, Computing Science, University of Aberdeen16 Recommendations l If done well, perceived very positively »Real benefit, not just marketing spam »Credit-card companies have done this well –Have the most purchasing data? l Data privacy issues »Can Visa sell data about you to Amazon? »Spyware to track all of your web browsing?

Dr. Ehud Reiter, Computing Science, University of Aberdeen17 Personalise Web Sites l Let customers create their own shop front focusing on their interest l Adjust appearance (eg, for visually disabled, or strict Muslims) l Doable, not huge success

Dr. Ehud Reiter, Computing Science, University of Aberdeen18 Personalised Pricing l Companies would love to be able to charge people different amounts for the same product »Airline seats, cars, etc »Full price for people who are keen, in a rush, dont care about money »Discount for choosy/finicky

Dr. Ehud Reiter, Computing Science, University of Aberdeen19 Personalised Pricing l Amazon, etc have tried this, but customers hated it. l So has gone underground for now. l Technology permits this, but societys expectations does not allow it

Dr. Ehud Reiter, Computing Science, University of Aberdeen20 Advertising l E-Shops (and other sites) can make money via advertising »Google makes billions from its sponsored links »Amazon has adverts as well

Dr. Ehud Reiter, Computing Science, University of Aberdeen21 Web Advertising l Conventional advertising focuses on visual appeal l Less successful on web »Flashy animated banner adverts are a nuisance and distraction

Dr. Ehud Reiter, Computing Science, University of Aberdeen22 Targeted adverts l Web allows relevant adverts to be associated with a web page »Google sponsored links based on search »Amazon could display different adverts for sci-fi and romance novel l Very effective if done well »So Web sites can charge more for targeted adverts

Dr. Ehud Reiter, Computing Science, University of Aberdeen23 Web adverts l Initially treated like TV adverts, put huge effort into flashy multimedia banner ads l Now focusing on simple targeted adverts instead l Advertising models cannot be blindly moved from TV to web »need new models!

Dr. Ehud Reiter, Computing Science, University of Aberdeen24 E-Commerce Summary l Initially tried to make e-shops similar to high street shops. But »Need different business model »Trust issues much more important »Need appropriate legal framework

Dr. Ehud Reiter, Computing Science, University of Aberdeen25 E-Commerce Summary l Sometimes technology really helps »Recommender systems, targeted adverts l Sometimes technology works but society doesnt like it »Differential pricing
