CONSUMER INFORMATION
Many of the Internet sites that use dirty tricks are the ones
that would arrive in a plain brown wrapper if that were possible
on line, but even some G-rated Web sites use the same schemes.
Here are two techniques that are used by a software company to
keep unsuspecting surfers stuck to its pages.
A banner ad that looks very much like a system alert box
appears at the top of the screen. The surfer, fearing that
something has gone wrong with the connection, clicks O.K.
The software company’s home page appears. The surfer, now
realizing that the system alert box was really just a banner ad
with an embedded link, clicks on the Back button to return to
the previous page.
Instead of returning the surfer to the previous page, the
Back button (with some help from a sneaky piece of code) sends
the surfer to a pop-up box from the same company.

On the Web, dirty tricks are everywhere. Last month, would-be
visitors to 25 million popular Web pages were intentionally rerouted
to and then stuck at pornography sites. The incident brought to light
one of the annoying aspects of Web surfing: You cannot always go where
you want and, if you are in a place you don't want to be, you cannot
always get out easily.
Some side trips are the result of mistakes by surfers, but many are
the work of Webmasters who bend and twist HTML code into trapping
people in one spot like overeager used-car salesmen.
Sites that specialize in pornography are the most obvious
practitioners of user manipulation.
"From my experience, they were definitely the ones leading it,"
Daniel Glovich, the manager of Web development at the E-commerce site
Cybershop, said of the use of these tricks. "But then, like a lot of
things on the Web, everybody saw that it worked -- and followed."
All of these tricks are irritating. Some are downright deceptive.
The Federal Trade Commission filed an injunction against the parties
responsible for last month's page-jacking case. One reason the agency
took such aggressive action was that "there isn't a whole lot the
consumer can do," said Paul H. Luehr, assistant director of marketing
practices at the Federal Trade Commission. "They were deceptively
driven to these sites and then held there against their will." The
F.T.C. has a form on its Web site (http://www.nytimes.com/library/tech/99/10/circuits/articles/07tric.html#1)
and a toll-free number (1-877-FTC-HELP) for consumers to file
complaints about misleading sites.

headaches: disabled browser buttons and cloned search keywords.

Of course, creative coders are constantly thinking up new ways to
turn Web pages evil. Here are some of the more common and more
frustrating dirty Web tricks.
Breaking Your Back Button
You're clicking your way around the Web, exploring pages and
following links. On one site, you click on the Back button at the top
of the browser. Nothing happens. You click again and repeat until
bedtime.
Most likely, the button was intentionally disabled by the Web page
itself. The button may even be "grayed out" on some sites. Why does it
do this? To keep you right where you are so you'll look at the content
(and the advertising). This type of rude behavior was used in last
month's scheme: the user's Back and Home buttons were rigged to lead
to more pornography sites.
The dastardly deed is commonly performed with Javascript, a
powerful programming tool used with HTML, a common programming
language used for making Web pages. Programmers can use Javascript to
create a loop: Each time a window closes, a new one opens. Because the
window is "new," there is no Back button because the browser thinks
there is no place to go back to.
"Every time that window closes," Mr. Glovich said, "there's another
Javascript that will do the same thing. You try to close it, and it
opens up another one."
Is there any way out of these endless loops? "There really isn't a
way to beat it," Mr. Glovich said. "You just have to shut it down."
You can disable Java: most Web browsers will let the user do this
in the program's preferences. "There are some trade-offs in doing
that," Mr. Luehr said. "Turning off your Javascript reduces the power
and interactivity of the Internet in some respects."
A Game of Metatag: You're It
Has your favorite search engine ever brought back all sorts of
results that had nothing to do with your request? Take the tale of a
certain volunteer who was teaching a roomful of 10-year-old girls how
to use search engines during a Take Our Daughters to Work Day event.
(O.K., it was me.)
The class, being of That Age, wanted information on the pop star
Britney Spears. Back came the results, most from pornography sites
that had cleverly embedded variations on the Britney Spears name --
which the girls had misspelled -- in a special area of their pages
that search engines use for indexing.
A metatag is a place in the HTML code where information about the
page can be listed -- like who made it and how often they update it --
as well as keywords that indicate what the page is about. HTML coders
can put whatever they want in the metatags, including things that have
nothing to do with it. According to a recent list in a site that
tracks search terms, "MP3," "sex" and "Hotmail" were the most popular
search words. Imbedding popular terms in the metatags of a site on,
say, lobster traps in Nova Scotia will draw many more surfers, not
just the ones that searched for "traps AND lobsters."

avoid some tricks by turning off Java, but that makes Web
surfing less interactive.

Some companies will even imbed the name of business rivals into the
metatags on their own home page. "That way, if someone searches for
them, they'll find you," said Danny Sullivan, editor of the Search
Engine Watch site.
"It's kind of part art, part science, but they really know how to
work the search engines using metatags," Mr. Glovich said. "But
metatags are only a part of it. It's keyword density, how many times
that word appears in the document, in what locations in appears, in
what format does it appear in -- a bunch of things like that
contribute to the placement in the results. They totally know how to
work it, and it's not all that difficult to do."
The solution lies with the search engines, not the surfers. "Search
engines are moving away from crawling and just indexing anything
automatically," Mr. Sullivan said. "Now, what the search engines are
doing is relying on humans to categorize Web sites." Lycos and the
search engines on AOL and the Microsoft Network are adopting this
tactic, he said. "It's harder to spam, if you will, a human being," he
added. "You can't just flip it past them, because they're smarter than
a machine."
The law has already caught up with a few companies using
trademarked terms just to get search hits. Playboy has sued a number
of sites for embedding its name in their code.
Windows Begetting Windows
Have you ever called it quits after hours of surfing, closed your
browser window and discovered several other open browser windows still
on your screen, all neatly piled one on top of another?
That trick is also used to keep users connected to one site, even
if they are looking at another. The HTML code writer can tell the
browser to treat the desired link as a new window, which opens on top
of the first one.
Many sites use this tactic to smack you in the eyes with
advertisements, but also to display supplementary information or to
lead you to a different section of the site. Sites that specialize in
MP3 downloads are often guilty of this "window farming."
Some sites will open even more windows that contain paid
advertisements. "They get paid per view in general for these cases,"
Mr. Glovich said. "So the more they pop, the more they make."

One way to put a stop to this sort of thing is to visit your
favorite shareware archive for inexpensive little programs that keep
browser windows from breeding like bunnies. Intermute (http://www.nytimes.com/library/tech/99/10/circuits/articles/07tric.html#1)
sells such a program for $20.
Spellcheck Won't Save You Now
Everyone makes a typo now and then. Some of the craftier Web
entreprenuers rely on these slip-ups to send you to sites that you
were completely unprepared for.
Yahoo had the foresight to pay for an extra "O" and claim
www.yahooo.com as its own, which properly leads to www.yahoo.com. If
you don't know how it is spelled, though, and try www.yawhoo.com by
mistake, you go to The Net One, a different search site. In another
case of competitors trumping their rivals, www.microsoft.com leads to
the home page of Linux, the operating system that is challenging
Windows.
Sometimes, a transposed keystroke can be more problematic,
especially if you are teaching a child how to search the Web.
Mistyping www.excite.com can whisk you to a porn site. Missed
punctuation, like the period after the "www," may also result in
unplanned visits.
Some sites will gamble on your guessing wrong when you don't know
the exact address of a site. Many browser versions will let you type
just the middle part of the domain name, adding the "http://www." and
the ".com" automatically. A classic example of a sex site preying upon
unsuspecting users is a variation of the White House site address,
www.whitehouse.gov. If you want to drop Mr. Clinton a note, take
special note of the .gov suffix.
Two years ago, the Federal Trade Commission was involved in a case
in which an Australian company was selling domain names through a Web
site called http://www.nytimes.com/library/tech/99/10/circuits/articles/07tric.html#1
(as opposed to internic.net, the real site, run by Network Solutions).
The company was charging $250 for domain-name registration, sending
the regular fee to Network Solutions and pocketing the rest. As many
as 13,000 people in nine countries were duped.
Look, Don't Touch
Have you ever noticed two Web sites that look exactly like each
other except for the domain names and contact information? One may
just be a clever copy, made to steal the economic or creative thunder
of the original. And you may have no other clues that you are not
looking at the original site.
In last month's Internet case, as many as 25 million popular Web
pages were copied onto Web servers and code was added to reroute
viewers to pornography sites. When search engines displayed the fake
pages as search results and the users clicked on the links, they were
taken on a triple-X ride. Some people are slicker than others about
doing this type of thing.
"This is the equivalent of somebody taking a shotgun, pointing it
at the sky and hitting a whole bunch of ducks," Mr. Sullivan said. "It
wasn't subtle at all. In contrast, people who are really sophisticated
don't throw up 25 million pages and hope to pick up traffic."
The copied-pages syndrome often happens to sites celebrating
pop-culture icons like Xena the Warrior Princess, but corporate theft,
like stealing a business competitor's pages and changing the contact
information, also abounds. A successful digital communications company
had its Web site stolen by someone in Russia who presented it as his
own. (Fearing further security breaches, the company refused to
comment on the matter.) For the common user, though, paying close
attention to what is on the screen -- look out particularly for Web
addresses that bear little resemblance to the site name -- might be
the best defense.
What You See Isn't What You Get
A few years ago, when Netscape's Navigator was slugging it out with
Microsoft's Internet Explorer to be king of the browser hill, some
sites would optimize their pages for their browser of choice,
intentionally make their content look bad for the competition and even
block access to the site. Although these browser wars have pretty much
ended, a few stalwarts are probably still clinging to old grudges.
Another reason a page may look bad is that it was never intended to
be looked at in the first place. Some companies slap together Web
"landing pages," -- also called "bridge" and "spam" pages -- that are
meant to be seen, not by people but by search engines.
By playing these pages into a search engine's algorithm, businesses
that specialize in Web placement can boost a client's ranking on the
search results page.
"There are actually companies out there that their whole purpose is
just to create and maintain landing pages like that and redirect the
traffic," Mr. Glovich said. Although driving up search-engine results
is a lot harder now, he said, it was not that way a few years ago. "It
got to the point where, literally, inside of 10 minutes, you could
manipulate Infoseek and take over the top five positions for any given
query."
"It's definitely not that easy anymore," said Bill Rose, vice
president of search and content at Infoseek. "We have a lot of
technology that's analyzing the U.R.L's that people are submitting to
be sure they're not trying to spam or create bad search results."
Mr. Sullivan said that some major search engines were starting to
use different criteria to rank a page, like how many other pages are
linking to it. "If lots of links are pointing at it, then maybe it
will rank higher," he said. "It's a harder thing for somebody to go
through and try to manipulate for spam."
Advertisements in Disguise
Some Web links are intentionally misleading, or they will display
an advertisement before you can continue to your desired destination,
or they will camouflage themselves. One box on Alta Vista's Computers
and Internet page looks like a site-search line for hardware and
software, but clicking on it takes you to an on-line computer store.
Another increasingly popular trick is a banner ad -- the horizontal
strip of commercialism found at the top and bottom of Web pages --
disguised as something else, like a form to fill out or a trivia
question to answer. Yet another popular facade trick involves a
system-alert box.
Duplicitous banner advertisements can be designed by graphics
professionals to resemble ominous computer messages, and new users may
be nervous enough to click on anything that says "O.K." to make them
go away. Only after you end up in an unexpected sales environment with
a perfectly functioning computer does the ruse become apparent.
Next time you are on the Web and think your computer is complaining
about something with an alert box, look closely. Real system alert
boxes pop up in the middle of the screen and float above the active
window. Fakes are usually nestled right in there with the Web page
content.
Of course, Macintosh users will probably spot them right away --
most of the ads resemble Windows messages.
