Some are common sense and other may be harder to understand, but never the less here they are.
{1} The user must
know what the site is about in the first couple of seconds. Attention is one the
most valuable currencies on the Internet. If a visitor can not figure what your
site is about in a couple of seconds, he will probably just go somewhere else.
Your site must communicate why I should spend my time there, and FAST!
{2} Make the content
scannable: this is the Internet, not a book, so forget large
blocks of text. Probably I will be visiting your site while I work on other
stuff so make sure that I can scan through the entire content. Bullet points,
headers, subheaders, lists. Anything that will help the reader filter what he
is looking for.
{3} Do not use fancy fonts that are unreadable: sure
there are some fonts that will give a sophisticated look to your website. But
are they readable? If your main objective is to deliver a message and get the
visitors reading your stuff, then you should make the process comfortable for
them.
{4} Do not use tiny fonts: the previous point applies
here, you want to make sure that readers are comfortable reading your content.
My Firefox does have a zooming feature, but if I need to use on your website it
will probably be the last time I visit it.
{5} Do not open new browser windows: I used to do that
on my first websites. The logic was simple, if I open new browser windows for
external links the user will never leave my site. WRONG! Let the user control
where he wants the links to open. There is a reason why browsers have a huge
“Back” button. Do not worry about sending the visitor to another website, he
will get back if he wants to (even porn sites are starting to get conscious
regarding this point lately…).
{6} Do not resize the user’s browser windows: the user
should be in control of his browser. If you resize it you will risk to mess
things up on his side, and what is worse you might lose your credibility in
front of him.
{7} Do not require a registration unless it is necessary:
lets put this straight, when I browse around the Internet I want to get
information, not the other way around. Do not force me to register up and leave
my email address and other details unless it is absolutely necessary (i.e.
unless what you offer is so good that I will bear with the registration).
{8} Never subscribe the visitor for something without his consent:
do not automatically subscribe a visitor to newsletters when he registers up on
your site. Sending unsolicited emails around is not the best way to make
friends.
{9} Do not overuse Flash: apart from increasing the
load time of your website, excessive usage of Flash might also annoy the
visitors. Use it only if you must offer features that are not supported by
static pages.
{10} Do
not play music: on the early years of the Internet web
developers always tried to successfully integrate music into websites. Guess
what, they failed miserably. Do not use music, period.
{11} If you MUST play an audio file let the user start it:
some situations might require an audio file. You might need to deliver a speech
to the user or your guided tour might have an audio component. That is fine.
Just make sure that the user is in control, let him push the “Play” button as
opposed to jamming the music on his face right after he enters the website.
{12} Do not clutter your website with badges: first of
all, badges of networks and communities make a site look very unprofessional.
Even if we are talking about awards and recognition badges you should place
them on the “About Us” page.
{13} Do not use a homepage that just launches the “real” website:
the smaller the number of steps required for the user to access your content,
the better.
{14} Make sure to include contact details: there is
nothing worse than a website that has no contact details. This is not bad only
for the visitors, but also for yourself. You might lose important feedback
along the way.
{15} Do not break the “Back” button: this is a very
basic principle of usability. Do not break the “Back” button under any
circumstance. Opening new browser windows will break it, for instance, and some
Javascript links might also break them.
{16} Do not use blinking text: unless your visitors are
coming straight from 1996, that is.
{17} Avoid complex URL structures: a simple,
keyword-based URL structure will not only improve your search engine rankings,
but it will also make it easier for the reader to identify the content of your
pages before visiting them.
{18} Use CSS over HTML tables: HTML tables were used to
create page layouts. With the advent of CSS, however, there is no reason to
stick to them. CSS is faster, more reliable and it offers many more features.
{19} Make sure users can search the whole website:
there is a reason why search engines revolutionized the Internet. You probably
guessed it, because they make it very easy to find the information we are
looking for. Do not neglect this on your site.
{20} Avoid “drop down” menus: the user should be able
to see all the navigation options straight way. Using “drop down” menus might
confuse things and hide the information the reader was actually looking for.
{21} Use text navigation: text navigation is not only
faster but it is also more reliable. Some users, for instance, browse the
Internet with images turned off.
{22} If you are linking to PDF files disclose it: ever
clicked on a link only to see your browser freezing while Acrobat Reader
launches to open that (unrequested) PDF file? That is pretty annoying so make
sure to explicit links pointing to PDF files so that users can handle them
properly.
{23} Do not confuse the visitor with many versions:
avoid confusing the visitor with too many versions of your website. What
bandwidth do I prefer? 56Kbps? 128Kbps? Flash or HTML? Man, just give me the
content!
{24} Do not blend advertising inside the content:
blending advertising like Adsense units inside your content might increase your
click-through rate on the short term. Over the long run, however, this will
reduce your readership base. An annoyed visitor is a lost visitor.
