Common Mistakes in Web Site Design
Your web site is in many cases the first impression
a potential customer gets about your business.
You have about 30 seconds to make that impression
count.
Unfortunately all the good intentions in the world
will not make your web site effective (at selling and persuading) if it is badly
designed. Here are the most common errors:
Slow Pages
Why don’t people like to wait? They don’t like to
queue. They don’t like to wait to see someone, to have something delivered, to
be replied to. Its part of the Western way of life that we are indoctrinated
from an early age to fill our lives to the brim with interesting and
constructive activities. Waiting is not one of those. We spend millions on ‘time
saving’ gadgetry, we drive fast to get wherever we’re going quickly. So, where’s
all this time we’re saving? Do we build up a great credit by the time we reach
70? Of course not. We fly home at the end of the day to lie in a chair with beer
in our hand.
New technology of course has to perform – and be quick about
it. The internet, as we’re told repeatedly in emphatic terms, is the new
frontier, the information superhighway. Superhighway? An overladen donkey
staggering down a rutted cart track would be faster.
So, when it comes to
the Internet, we have even less patience than we would queuing for a loaf of
bread or a tank of gas.
Its been said plenty of times before and is
consistently the number one complaint by those who use the Internet – slow pages
frustrate and irritate and are almost guaranteed to send users
elsewhere.
This is particularly true in this part of the world where
broadband is virtually unknown and dialup connections are the rule. Even where
broadband is popular, a snappy download will be appreciated. Having extra
bandwidth shouldn’t be an excuse to load pages with doodads.
Let’s face
it, people don’t like looking at web pages. Its not the pages of course, just
the experience. Give them a book with all the information they seek in it and
they will be happy, flipping to and fro for hours.
Even after the site
has downloaded, reading the pages is at least 25% slower than reading from a
book – and that is if the type on the page is readable.
The technical
reasons for slow pages are easy to find – graphics, connections and the like –
but the real reasons are more subtle.
Ignorance
Sometimes on the part of the web designer but more
likely on the part of the client.
Slow pages are a recurring theme on the
Internet so most designers will have read something on the subject and be aware
of the problem.
In any event, many HTML editors have a ‘Document Weight’
tool that gives web designers an idea of the length of time the page will take
to download at various modem speeds. These are useful but only in a relative
way.
Firstly, although they measure page size and associated image and
script sizes, they normally do not include images used as backgrounds, which can
be very large in some cases. Secondly, they cannot anticipate the users
immediate environment. Many users download more than one page at once which
slows everything down even more.
So, although a Document Weight reading
will indicate a download time of 10 seconds, in practice, this will be nearer 30
– 45 seconds, particularly if it’s the first page of a site and no images are
available from the browser cache.
Clients will generally have Internet
experience at some level and have endured their fair share of slow pages.
However, THEIR new site won’t be like the others, regardless of the fact that
they want to cram 100kb of photos onto the front page along with a variety of
animations and their logo writ large upon the header.
Clients compound
the problem by requesting such sites from designers. It is the old ‘cup holder’
competition that raged between two vehicle manufacturers in the US recently that
ended when one manufacturer managed to incorporate no less than 17 cup holders
in a car. “If the competition has three animations, then it stands to reason
that four must be better”.
It is this ‘if a little is good, then more
must be better’ syndrome that ruins many pages – not only with graphics but also
with other aspects of site design.
Many clients regard a ‘busy’ web page
– one that has lots of complex graphics and animations – as a good page. It must
be good – look at all the gorgeous graphics, the animations, the link farm, the
jazzy, fading buttons and the wall–to-wall text. If it has a migraine-inducing
Flash animation, so much the better.
Many designers will collude with
clients and their requests just to get the job. Telling the client to ditch just
about everything on the front page – including the grandkids photo is not going
to bring a smile to their face.
Once their site is complete, they of
course will manage to wait the two minutes for the masterpiece to appear. Their
clients won’t.
Web designers know clients are usually impressed with
‘razzle dazzle’ of course and if asked, will be happy to provide it. The client
is delighted and shows his new site off. He says smugly to his friends “Of
course we have Flash and tremendous graphics with lots of curves, gradient fills
and drop shadows not like our competition with its plain old site. Cost us a
fortune but its worth it.”
He is not so delighted if he sees his server
log and under ‘average time spent in site’ it says 37.4 seconds. Even if he
doesn’t see his log, after a few months, there are few enquiries. He is now
convinced that the Internet is a waste of money. In the meantime, his lowly
competitor’s visitors have seen his site download chop chop and been through his
twenty or so pages to see what he has to offer and off out again, all within a
couple of minutes. Mr. Bigmouth’s visitors are still waiting for the Flash to
finish.
And what will the latter’s visitors remember? The disco-like
Flash? The 3D graphics?
Nope – just the interminable length of time it
took to see anything on the screen. Will they come back to see his Newsletter?
His new service?
Ego
The worst offender is often the web designer left
to his own devices by a client with little Internet experience. The temptation
to go berserk on the site is heightened by the fact that if the site is a
disaster, he can explain it away in highly technical terms and blame the client
for a lack of strict guidelines and a parsimonious budget.
Many web
designers come from a graphics background and may be strong and competent in
that area and less so in the technological side of site design. It is natural
therefore that graphical aspects of sites from such designers may overshadow and
in some cases overwhelm the design.
The web designer isn’t always to
blame in this regard.
The web designer for a large corporation may be
employed by them but will probably in any case be at the bottom of the ego food
chain. Above him will be the sales department, the marketing department, the PR
department, graphic design section and finally, if he’s lucky, the bloke who has
to cobble the whole sorry mess together.
Graphics
‘A picture is worth a thousand words’ –
actually about twenty thousand in many cases in web pages. If it’s not
necessary, leave it out. If it doesn’t add value to the page, leave it out. If
it cannot earn its place, leave it out.
Most graphics are too large
anyway, rather halve the dimensions and quarter the download time. Many
designers are beloved of the enlargeable thumbnail. In many cases, the
thumbnails are so small as to be indecipherable. Anyone enlarging such a
thumbnail will do so simply to find out what the thumbnail was actually of. A
properly treated photograph can be displayed with all its information visible in
a form little larger than a thumbnail.
Poor cropping is at fault in many
cases. Rather choose just a portion of a picture – the message will still get
across. Instead, we get the 10 pixel high squiggles that are supposed to
represent a herd of buffalo. Photos taken with the average lens will include a
fair amount of ‘sea and sky’ – crop out the top and bottom 25% of the picture
and save time.
Stitching several of these ‘panorama’ aspect photos can
yield a realistic effect without waiting for hours for it to
download.
Some people just love videos. All should come with a warning
related to the huge file size. Walk-throughs are similar and apart from the huge
file size, most of the content is of questionable relevance.
Corporations
love the ‘office clipart’ pic – the telephonist, the earnest consultation, the
euphoric purchaser, the computer keyboard. I’m not quite sure what they think
such pics add. If they were smaller, I could condone them but not when they’re
7kb each.
JPEGs
Useful for full colour graphics like
photographs but should not be used in high contrast situations like graphic text
on a plain background because of all the edge artifact that occurs.
JPEGs
can be compressed almost to nothing but it is a ‘lossy’ compression and as the
compression ratio increases, so do the ‘blocks’ of the image increase in
size.
A common problem with JPEGs is over sharpening which results in a
‘scratchy’ image – and an increased file size. For maximum effect, JPEGs should
be very slightly fuzzy with saturated colours.
GIFs
A maximum of 256 colours but can still render
most small photographs well. A colour can be chosen for a transparent background
that can yield many interesting effects.
Unlike JPEGs, the number of
colours can be reduced - to 2 if necessary – minimizing the file size. For some
reason, when large blocks of colour are called for in a web site, many designers
opt for huge GIFs rather than the use of table or DIV background
colours.
The problems related to GIFs are mainly two, and they’re
related. Drop shadows and gradient fills.
They are less seen now than
before but their effect is to increase the file size significantly. Because its
just a push of a button to create these effects, web designers love them – they
add pizzazz to an otherwise very average image. There are ways of creating a 3D
effect in many cases that do not involve drop shadows.
Bevels are much
used by logo and button designers and have a similar effect on download time.
Masks can yield impressive effects but also can increase download
time.
There is a place for all these effects but the overhead that each
of them add to the page weight must be checked all the time to ascertain whether
they are acceptable.
Flash Animation
Gif and Java/Javascript animations are but
small cheese to the Big Daddy of them all – Flash.
Apart from being the
worst offender, it unfortunately is the most impressive example of graphic
‘razzle dazzle’ and therefore the most persuasive.
In a bewildering way,
web designers in their own right, and big corporations love Flash. I have lost
count of the number of times I have left pages because of excessive use of Flash
– picturesquely known as ‘Flashturbation’.
Flash almost inevitably is
found on the Home page – the most critical page in any web site. Occasionally it
stampedes untrammeled through every page in the site.
Some even come with
built in ‘progress bars’ in the vain hope that as long as a visitor can see
something happening, he will wait two minutes for the page to load. Many pages
come without a ‘Skip’ link to get rid of the Flash.
This is contempt of
the worst sort.
Firstly, you are forcing the visitor – from whom you are
hoping to part his money – to download the Flash plugin. Never mind that he
probably already has it, you are constraining him to your design. Is he going to
be so dribbling at the lips with the prospect of the wonders of your site that
he will sit while the plugin downloads and installs itself?
Secondly, you
are forcing your visitor to wait again while the whole animation loads –
sometimes well over a minute – and thirdly, many Flash animations are completely
bereft of any meaning and don’t even end up with a menu.
Fourthly, even
if there is a ‘Skip’ option, why force the user to click the mouse? The whole
subject of usability is to get the long suffering visitor through your site with
as few mouse clicks as possible and here you are, right on the Home page,
forcing him the use his mouse.
Lastly, and the ultimate insult, many
pages don’t incorporate a ‘Skip’ link. You are simply telling your visitor, your
valued visitor, that he must sit there and wait and watch your ego filling the
screen because you have spent a couple of weeks on the thing and besides – the
rest of the site, even though it hasn’t the benefit of my great Flash talent –
is brilliant.
If you have any aspirations at all about getting somewhere
noticeable on a search engine and you want a Flash intro then forget it. Search
engines hate Flash.
The sad fact is that often, the ‘rest of the site’ is
even more irritating than the Flash for a variety of reasons. Inexplicably, even
some web designers on their own sites use a Flash Home page and again, sadly,
clients are REALLY impressed with Flash despite the fact that it is expensive to
create.
Graphic Sea Anchors
If an image is to go on a web page, it must earn
its place there – every image. If it is absolutely relevant, then of course
include it. If it is incidental then look very hard at it. Yes, its “only 4kb”
but the 4kbs mount up. If it is to be included to break up the text and add a
little visual relief then reduce its size and colour depth and wash it out. It
will then be only 2kb or less and not distract the reading of the reason the
page exists in the first place – the content.
In the opposite of print
media, Internet visitors look at text first and pictures after. And, to
paraphrase the aphorism ‘ a picture is worth a thousand words’ – in the world of
the Internet, it is worth several thousand words in download time – and that’s a
small image. Secondly, it may not be worth any words if it doesn’t add value to
the page.
Elaborate icons also inevitably add weight to pages. The
Warthog (www.warthog.co.za) site has 27 small graphics crammed into 7kb and yet
it is not uncommon to see a single icon take up 3kb.
Rollover buttons
using Javascript are still being used. Six buttons, six rollover states equals
twelve images. If each image is ‘only’ 2kb, that is 24kb and your visitor is
having to wait an extra 8 seconds or so just for your buttons to load. Style
sheet buttons can be just as attractive and take no time at all to
download.
Summary
Fast pages are good.
Attractive pages are also good but not as good
as fast pages.
High speed and quality content (another hot topic) are
two things paramount when putting a site together from the lowliest
couple-of-pager to a thousand page corporate site.
Producing an
attractive yet fast page is a balancing act but unfortunately, the balancing
pole is usually weighted to the graphics end.
