Wrong. That's an argument against using "click here" as the only link
text, but even still it's a poor argument.

This is a faulty assumption. Links in web pages aren't meant to be
yanked out of context. It's hypertext, and it's structured context
for a reason. Removing that context is harmful, and screenreaders
which do this are harmful, long-term, to the accessibility of the web.

It makes no sense at all to demand that web pages make sense when
individual links are read out with all structure stripped.

And, yes, there are many cases in which "click here" alone is just
silly, but it's not a huge accessibility problem, and yet I've been
amazed how many web accessibility folks seem to think that, oh my
gosh, we'd better fix that right away, it's a major error.

It's not. It's insignificant if someone uses the terminology "click
here" versus "follow this link."

Compare/contrast:

1. click here for "alt text,"
2. here for "alt tag",
3. and here for "alt attribute."

versus

1. follow this link for "alt text",
2. this link for "alt tag",
3. and this link for "alt attribute."

They're all identical, but you'll find people who would swear up and
down that "click here" somehow ruined everything, as if blind folks
using the web would have no idea what this alien "click" concept could
possibly ever mean.

I prefer "Kynn," by the way. If you're using a screenreader it may
sound subtly different -- K y n n.

This is an incorrect oversimplification of how sighted users approach
web pages. It's completely untrue that they gain nothing from
context. In fact, it is completely impossible -- visual users always
use the context when locating links.

For example, I am reading this in google mail. I know where to find
the "reply" and "forward" links, because of where they are visually
located on the page. That's because it's where I expect it to be,
based on the layout of the page.

There is also, somewhere, a link called "preview invite" and another
called "create a filter." I had no idea those were there until I
specifically went hunting. If you asked me, without looking at the
screen, to name the links on the page, I wouldn't have found those.

Why? Because they're out of the way, they're hidden over THERE and up
there THERE, where I can't see them because I don't look.

There's also a pair of links at the bottom which say:

Get the Gmail Notifier for the Mac. Learn more.

"Gmail Notifier for the Mac" is one link. "Learn more" is another.
Yes, "Learn More" doesn't make sense out of context, given that it
could be about anything on the page. There are other "Learn more"
links on the page. But it's also presented in logical, structured
order, and if I broke that order, it would fail to work as well.

(Note: I'm not holding up Gmail as an example of accessible design,
but rather using it to illustrate how visually dependent users are
forced to process information, due to our dependency.)

No, it's a different kind of functionality.

Because "click here to buy tickets" has increased usability for
everyone, actually.

I also think you're not reading carefully what I am saying. You
probably should, because it is more complex than what people are
usually taught about web accessibility, which is simplifications such
as "click here is bad!"

"Click here" is neither good nor bad. And trying to argue that it's
necessarily bad because some people intentionally break the structure
of structured markup and then attempt to use a page is a poor, poor
argument.

They're always redundant. What else do you do to a link besides
click/follow it online? The very premise of html is the HYPERTEXT part
of it. Links are what make the web what it is.

> Most links aren't all that explicit about what they do.

That's exactly why 'click here' is bad practice.

I did that just yesterday. I was on a site that was basically directing
me to other sites that had the potential to provide me with the detailed
information I was looking for. What was emphasized on the page (and thus
drew my eyes) were the links. Unfortunately, all of the links said
"Click Here". Visually scanning that page for what I was looking for
felt very clunky and counter-intuitive.

Except, not all of the links said "click here." There were navigation
links all over that page which said plenty of things besides "click
here."

Not necessarily. Sometimes they they're helpful and increase the
usability of a page.

Most links aren't all that explicit about what they do. Many times it
actually is helpful to specify what a link is all about. And hiding
it in title attributes isn't always the best.

I can't say that I agree with you here Ken. When a sited person visits a
page looking for a link to take him or her to more information about
something that he or she knows is mentioned within a page, they will
frequently do this by visually scanning the links on the page. (Gaining
nothing from context) The link list feature of screen readers allows
blind users to gain that same functionality. Well chosen link text helps
both the sited and unsited alike in this situation. Example: I have
arrived on a page promoting an event that I would like to attend. I want
to purchase tickets to the event but don't want to bother reading all
about the event, I already know I want to go. If the page has 30 links
that say nothing but "Click Here" with the contextual phrase that tells me
where I am going either before or after "Click Here" it takes me a lot
longer to find the link to the tickets visually, and I cannot do it
without listening through the page using a screen reader. If instead
there is a link that says "Purchase Tickets" I can get my tickets quickly
whether I am scanning visually or using a link list on a screen reader.
Of course the link text could be "Click Here to Buy Tickets" but why
bother with all the extra words.

Yes. Both are bad practice. Both from an accessibility standpoint and
just in the fact that they are completely rudundant in the context of
the web.

And that's fine, because all links do the same thing, namely nothing.
Links are data (indicating relationships), not commands or programs.

The link text is supposed to tell that, with the textual content giving
additional information. But it's not about what a link _does_. It's about
the resource that the link points to, especially in the context of the
referring document.

The title attribute was originally a useful idea, but it has largely been
spoiled by abuse. The title attribute is never the best way to specify
what a link is all about.

You might think so, but in fact they _are_ yanked out of context, just as
normal text is. Search engines do it all the time. People do it all the
time.

> It's hypertext,

Hypertext is text that contains links. There's not much magic in it, and
it's not an ideology. In the early days of the web, there were many people
who exaggerated the use of links - even saying that every word should be a
link (to a dictionary entry if nothing else). Experience has shown that it
is better to use links mostly as organized into link lists or as
references used sparingly e.g. at the end of a document, a section, or
perhaps a paragraph. Pure inline links tend to make texts harder to read,
and they make many people nervous, since they don't know whether they
should follow every link or not. They are not comfortable in speech
browsing either. When you hear a link in the midst of a statement, you
have little way of knowing whether you should follow it or not, and
following it later is not convenient. It's better to have things read
first as text without links, then perhaps followed by a statement like
"The document [link] foobar contains more detailed information about
[link] zip and [link] zap."

> and it's structured context for a reason.

Structured context? Structure and context are two different things.
Anyway, for _understandability_ especially to people with cognitive
disabilities, the text should be as readable as possible "out of context"
too. If the reader has to remember much of the context, many people simply
won't, even if they have no serious _intellectual_ difficulties in
understanding the content.

Aiming at link texts that are understandable out of context helps to make
the entire text more understandable.

It's a common mistake that is easy to fix, once people understand the
issue. This is a good reason to keep reminding of it - which is a
relatively new message being carried out. Actually I had never seen a
document summarizing the basic arguments against "Click here", so I
wrote one: http://www.cs.tut.fi/~jkorpela/www/click.html

When a blind person starts using the web, he may or may not have an idea
of what "click" means. It is still an unnecessarily alienating expression.
Besides, it gives misleading information to _everyone_. On all browsers I
have used, clicking on a link is (at most) _one_ way of following a link,
and other methods can be more suitable in particular contexts. Many people
are ignorant of the other methods, and "click here" helps in keeping them
ignorant.
