Creating effective web presence
1
Strategic Premise
Building a Web Site for an Enterprise or
Non-Profit is Not an Exercise
in Either Technology Or Aesthetics.
It is an Exercise in Creating Satisfying
Customer Experience in a Way that Leads to
Cost-Effective Execution of Marketing Strategy.
COMP7880-web-2
Effective Execution of Marketing Strategy





Building Web sites that deliver satisfying
customer experience and do so in a way that fits
both strategy and budget.
Visual attractiveness is a plus, but not a
necessity.
If technology gets in trouble, it is a negative, not
a plus, e.g., flash intros/demos.
Web sites is an important marketing strategy but
not the only one - that must be cost-effective.
Most Web sites should eventually be expected to
produce a reasonable return on investment.
COMP7880-web-3
Web Site Development Process




Not too different from marketing / communications planning
Planning a Web site should be first
Foremost a business/marketing planning process
Good business sense should take precedence
COMP7880-web-4
Establishing Site Objectives

Enterprise/Unit Marketing Objectives



cascade with levels
The Interactive Nature of the Internet

Communications/Branding Objectives

Behavioral Objectives
Role of Web Site on Overall Marketing/ Marketing
Communications Strategy

integration of online and offline strategy for multichannel marketers
COMP7880-web-5
Identify / Describe Target Market

Demographics, Life Styles

Motives for using the site

Tasks they wish to perform

Consider utility and customization

Stepwise scenario development / use case
analysis
COMP7880-web-6
Site Content / Navigation Structure

What content do visitors need/expect?

How do they access content?


More than just a straightforward replication of offline content

Interactions

Marketing research
What role should visuals/graphics play?

Simple and Usable

Content and structure more important
COMP7880-web-7
Typical Site Hierarchy



Enough second-level pages to clearly categorize content but not create
confusion
Visitor should never be more than 2-3 intuitive mouse clicks away
Avoid dead ends 
COMP7880-web-8
Site Design Issues
Content
 Navigation
 Color (especially background)
 Font
 Minimize Scrolling
 Artwork
 Animation/Graphics/Rich Media

COMP7880-web-9
Deployment and Tuning




Uploading site server / hosting service raises
many technical issues
Calibrating and fine tuning for best site
performance is highly technical
Reliability and scalability issues
Test at your target customers’ regions and
environment!
COMP7880-web-10
Measure / Evaluate / Improve
Performance & Effectiveness


Measuring and Improving site performance is
a technical task
Measuring and improving the business
effectiveness of site is a marketing task
COMP7880-web-11
Measurement Techniques

Concept Tests - basic marketing research techniques

Prototype Tests - tests of sites with limited functionality,
usually done in a laboratory setting.

Beta (Functional) Tests –

testing a fully-functioning Web site.

can be done in a laboratory setting or by giving trusted
users/customers access to a site on a server, before the site has been
deployed to the Web.

Customer Usability/Satisfaction Feedback - uses conventional
marketing research techniques to measure satisfaction with
the Web site experience.
COMP7880-web-12
Measuring Web Customer Satisfaction



Employs research methods developed offline
Adapted for the online environment
Single measures vs multiple measures

COMP7880-W2-22
The Power of Clickstream to Produce
Internet Metrics


Tremendous amount of data produced on the
Internet.
One of the main challenges for the Internet marketer
is to control this data to improve existing marketing
programs and to gain insights into additional
marketing efforts that have a high probability of
being productive
COMP7880-web-23
Purpose of Usability Testing
Visitors expect smooth navigation suiting their
need
 To be pleased and not frustrated
 The fundamental basis of Web site usability is
user task performance.
• Visitors come to the Web site motivated to
accomplish some goal, to perform some task.
• Usability testing is designed to ensure that task
performance is not only possible, but hopefully
efficient and entirely satisfactory.

COMP7880-web-24
Types/Stages of Usability Testing



Concept Testing - testing site design concepts
to see if they make sense. This is primarily site
structure, not design approaches.
Prototype Testing - testing prototypes to see if
they fit the manner in which users expect the
site to be organized and laid out in order for
them to complete tasks in an orderly fashion.
Full Usability Testing - Testing the full usability
of the site when it is functionally complete and
most if not all of the content is there.
COMP7880-web-25
Pareto Curve for Usability Testing

Over 75% of the problems can be identified with 5
user tests; only 15 are need to find 100% 
COMP7880-web-26
No Website can Ignore the Need for Usability
Testing



Usability testing is critically
important.
A careful marketer can
learn to do it, especially
one who has had focus
group training or
experience.
It can be outsourced to
interactive marketing
agency or a specialized
marketing services firm.
COMP7880-web-27
Site Performance Metrics
COMP7880-web-28
Traffics & Audience Metrics

Site Administered


Hit Counters
Purchased Services

Server Request Log Data

Coded Web Pages

Customer Panel Data
COMP7880-web-29
Hit Counters are Often Free
They Provide Simple But Useful Reports
COMP7880-web-30
What is a Server Log?



Server logs record every hit (every file
requested) and most pages have many files.
This is a necessary lead-in to understanding
that the IT people use server log data to run
the site and marketers use it (after much
processing) to understand the performance of
their marketing programs.
Includes, e.g. IP address, date and time of
request
COMP7880-web-31
Basic Metrics – Site Traffic

Hits



Impressions.



recorded each time a file is requested
little value in measuring site effectiveness.
Typical advertising usage applies here.
Each time a visitor has an opportunity to view an
item, an impression is recorded.
Page views (page impressions).

recorded each time a page is requested.
COMP7880-web-32
Basic Metrics – Site Audience





Visitors - simple count of the number of people who visit
a site
Unique visitors - the number of different people
Identified visitors - the next step up; now we know who
they are
Unduplicated audience - the number of unique
visits/exposures in a specified time frame.
Traffic and audience measures are obviously related.


Traffic simply measures the activity on the site.
Audience measures are of more interest to marketers who need
information about the composition of that traffic.
COMP7880-web-33
Need for Ratings





Management to assess performance
Investors to assess potential & returns
Advertisers for traffic numbers
Must be accurate & verifiable
External audit is the preferred option
COMP7880-web-34
Television Ratings






Create-once-sell-many medium
Production costs don’t change with number of
audience
Producers cannot directly count their audience
Independent panel-based measurement companies
are preferred, e.g. ACNielsen
Survey a representative sample of viewers and the
TV channels to which they tuned
Set-top box is used to record the viewing behavior
COMP7880-web-35
Magazine Ratings






Create-many-sell-many medium
They can count how many copies printed & sold
No way to count magazines actually opened and read
Independent companies verify circulation numbers
based on audits of financial documents, mailing lists,
postal receipts, and printing bills
Survey is much harder than TV as the number of
magazines is much higher than TV channels
No mechanism similar to set-top box
COMP7880-web-36
Web Ratings







Create-once-sell-many medium
Supply side resembles magazines but demand side
resembles TV
Can count using server logs how many pages were
“printed”
Can install set-top box like software to record viewing
behavior
Millions of web sites with billions of web pages require
prohibitively large samples
Representative samples are impractical to put together in
addition to difficulty of installing measurement software
Don’t guess but count!
COMP7880-web-37
Something You Can Know




The referral links let you know how much
traffic is coming from where?
Also captured are the search terms visitors
typed into portals like Yahoo!
Can discover the most-used entry and exit
pages
How long did they stay on each page?

Page Impressions

A measurement of responses from a web
server to a page request from the user
browser, which is filtered from robotic activity
and error codes, and is recorded at a point as
close as possible to the actual viewing of the
page by the user browser.
COMP7880-web-45
Clicks



A measurement of the user-initiated action of clicking
on an ad element, causing a re-direct to another web
location.
Tracked and reported as a 302 redirect at the ad
server.
This measurement is filtered for robotic activity and is
recorded at a point as close as possible to the actual
viewing of the destination web location by the user
browser.
COMP7880-web-46
Uniform Use of 302 Redirects




All 11 participants track clicks &
share a common definition
A click is a user-initiated action of
clicking on an ad element causing
a redirect to another web location
A click does not include
information on whether or not the
user completed the redirect
transaction
All base click metric on 302
redirects (or transfers)
successfully processed by the ad
server
