Introduction
"Flag Store Online" is a site dedicated to the
sale of flags, flagpoles and accessories. Ordering can take place online,
by telephone or by fax.
The home page of the site links to areas for specific
types of flag or accessory. It also links to an ordering section, and
a contact section.
Little information can be found on the background of the
site, as the "About Us" link results in an error page.
2. Usability Analysis
2.1 Accessibility
Page titles
Throughout the site, the page titles reflect the content
well, for example home page contains the title "Flag Store Online",
and the U.S. Flags section contains the title "U.S. Flags".
This is maintained throughout the various sections.
"Alt" tags
Most pages contain a banner-type image containing the
site logo. This image contains no "alt" text.
Other images, for example the linked flag images on the
home page, do contain appropriate "alt" tags.
Use of Images
Images are used sparingly, or only when necessary throughout
the site. Pages load quickly, and the information is displayed in a
clear manner.
The company logo does not act as a "home" link.
This is a popular and easily implemented method to allow the user to
return to the home page at any stage.
Errors
In
total, the site contains 77 "broken" links (links resulting
in a "Page Not Found" error). These links include some options
on the main menu, as well as many "Order" links within the
site.
While most of the product sections contain functioning
pages, the "Ordering By Phone", "FAQ", "Customer
Service" and "About Us" pages do not work. As a result
it is difficult to obtain online assistance or find out more information
about the company.
2.2 Navigation / Site structure
The home page, and some of the interior pages, contain
a long left-hand navigation bar. Though this is a tidy approach, the
number of links may be overwhelming.
It is not immediately apparent what the difference between
"Indoor Flags & Sets" and "Indoor U.S. Flags &
Sets".
Other sections could be combined, such as "Miniature
U.S. Flags" and "U.S. Flags".
Multiple missing pages give a bad impression, and do nothing
to reassure the user that the site is a genuine, professional company.
2.3 Consistency
Some
pages retain the navigation described above, along with the layout (for
example, "State & Territory Flags") while others discard
the navigation completely (for example, "U.S. Flags").
The background colour changes (from blue on the home page,
to white on interior pages) and on some pages several fonts are used
where one font should be used.
In the "U.S. Flags" section, three links lead
to pages of flag listings. On these pages, the site logo is not used.
Trying to return to the home page from these pages is
not possible without using the browser's back button, as the "home"
link on each page results in a "Page Not Found" error.
2.4 Ordering Process
In each product section, the products are listed in tables,
with their size, price, and sometimes, an item number. On the right
of each is an "Order" link.
On
most of the "U.S. Flags" section, the order link results in
an error page.
When the order link works, it results in a secure section
of the site, containing an order form.
It soon becomes apparent that though the "order"
link was situated beside a specific product, the information is not
carried across into the form. Instead, it is necessary to enter the
item number, size, description and price by hand. It is also not possible
to order more than seven items.
There is no total indicated on the form, yet the form
asks for credit card information on the same page.
Some information is marked as a required field, using
an asterisk. This is clear and easy to see. However, on submitting the
form, the information is not checked for missing or invalid data.
Once the form is submitted, the user is still not informed
of the total or order content. Instead the user must print a page, and
write by hand the time of the order, day and date ordered.
2.5 Ease Of Use
While the home page navigation ensures that it is not
difficult to locate a specific flag or accessory, the order process
offers little or no assistance, and is almost impossible to use.
To fill the order form, it would be necessary to either
take note of order numbers, sizes and prices, and fill them out on the
form. If a user returns to the site, perhaps to check a flag size, the
information on the form is lost and should be retyped.
As there is no error checking in place, the user is not
told of any errors. For example, it is possible to mistype a credit
card number, and because the site does not check the syntax, the error
is not alerted.
The navigational obstructions offered by the multitude
of missing pages would only slow or frustrate the user.
3. Conclusions & Proposed Improvements
While the home page of the site is clear and relatively
easy to use, there is inconsistency within much of the interior of this
site. Colours, layout and fonts are not consistent. It would be an improvement
to offer a consistent interface, with tested links that work.
A more streamlined navigation area would help users locate
their choice of item more quickly. Similar sections could be combined
under one heading, so that the user is not presented with an overwhelming
number of options.
Aside from the missing information, the most troubled
area of the site is the order form. Offering no feedback or error checking,
the form places unnecessary demands on the user, and could result in
errors or lost sales.
JavaScript form verification, and the use of cookies to
store users' purchase choices could improve the functionality of the
form, streamline the ordering process and result in fewer errors.
In terms of maintaining the site, the <font>
tags and inline CSS commands will be removed and stored as CSS definitions
in a separate CSS file. Multiple redundant tags add bulk to the page
size, and are considerably more difficult to edit than when stored in
a CSS file. The separate CSS file would save time both for the users
and the developers.
