e-Visibility v Getting the site noticed and the online customers visiting the store. v e-Visibility v Getting the site noticed and the online customers visiting the store. v Ways of advertising a web presence and getting customers in through the door include: § Site Name § Conventional Advertising § Portals § Malls § Search Engines § Links § Personal Recommendations E-Commerce ©David Whiteley/Mc. Graw-Hill, 2000 4

e-Visibility – site name v The surest way of finding a site is the e-Visibility – site name v The surest way of finding a site is the url. v If the url is memorable then the site is made: § amazon. com v A sensible simple site name can be guessed by users: § britishairways. com E-Commerce ©David Whiteley/Mc.

E-Commerce ©David Whiteley/Mc. Graw-Hill, 2000 6

e-Visibility – portals v The first page a user sees is the portal. v e-Visibility – portals v The first page a user sees is the portal. v An advert on a popular portal is the web equivalent of a TV advert at half time in the cup final or in a break during the Superbowl – it is seen by millions. v An advert on a popular web search engine is a similar piece of property. v Adverts on the portal can be: § Banners § Little boxes § Menu of services E-Commerce ©David Whiteley/Mc. Graw-Hill, 2000 7

e-Visibility – malls v An Internet shopping mall models itself on the American shopping e-Visibility – malls v An Internet shopping mall models itself on the American shopping mall, a lot of shops, under one roof with a pleasant shopping atmosphere. v The intention is to generate interest and thus trade for all the shops. v An Internet mall can provide common services. Possibilities include: § Shared advertising. § Common facilities. § e-Cash. § Common customer files. v The drawback of joining a mall is that, as for any good retail location, the rents can be high.

e-Visibility – search engines v A search engine is a standard way to find e-Visibility – search engines v A search engine is a standard way to find any Internet site and that includes e‑Shops. v Finding a specific e-Commerce site may or may not be easy - a successful e-Shop could do with appearing in that top ten list of hits. v The search engines index the web by: § Manual indexing; § Automatic Indexing (web crawlers). v Crawlers look at: § The tag is a prime target. § The <META> is also checked … and many other aspects of the site and its use, v Also one can ask the search engine to list the site. v Note, the best of the search engines list only about 15% of internet sites.

It is less information than would be required to open a bank account but more than is normally needed to buy some cornflakes. v Providing this information raises privacy issues: § Will the information be put to other uses? § Will the e-Vendor compile a customer profile? § Is the information secure? v The context in which the e-Commerce vendor asks for this information is also important: § Customer registration prior to using the site § Customer details only when an order is placed.

People that are frustrated with the site don’t bookmark, don’t buy, don’t revisit, and won’t tell other people about the site. ” (Rhodoes, 1999) v Site navigation is aided by: § A site index; § A site search engine; § Logical sequencing of facilities with clear links to the next stage in any process.
