Cloaking and Page-Jacking
by Michelle Anderson
"Page-jacking" is the new artform whereby unscrupulous webmasters copy
popular sites such as Microsoft and the Harvard Business Review to their own
servers and use a cloaking system to deliver those stolen pages to search
engines.
Once the search engine spiders find the pages, they are indexed, and
unwitting surfers looking for, say, Microsoft, would click on what they thought
were going to the Microsoft site and would be instead page-jacked to an
unrelated site which used this method.
Last year, the FTC "cracked down" on pagejacking, bringing the technique to
the attention of the general public.

"Cloaking" or "IP Delivery" is a technique which allows you to deliver
different pages for the same URL based upon the IP address of the requesting
agent.
When the server receives a page request, a script checks the IP address of
the user agent (or browser) using a database of known search engine IP
addresses. If a match is found, the server delivers an optimized, "search engine
friendly" page for the spider to index. This page is optimized for each search
engine, according to each search engine's algorithm. These pages are invisible
to the regular user.
If no match is found, the requesting user agent is sent to the page the
public sees.
In other words, cloaking shows an optimized doorway pages to the search
engines while displaying different and beautiful pages to human visitors.
Aside from the obvious advantage of being able to feed the search engines
pages which are specifically designed for high placement, IP delivery also hides
the meta tags from anyone who might want to steal them to boost their own
placement.
While IP delivery is clearly appropriate and ethical when used, say, to
optimize a page which is only a flash page or just a graphic, the potential for
abuse is there.
Anyone can learn to write their own cloaking script at sites like the one at

from $25 to more than $1,000.
An interesting situation arose last month, when a search engine optimization
firm filed a complaint with the FTC about another SEO firm allegedly pagejacking
using cloaking. The two principals made appearances at
SearchEngineDiscussion.com, each airing his own side of the case.

Is cloaking ethical? When used appropriately, yes. The problem is that since
everything is hidden, webmasters and search engine optimizers who use this
technique are on their honor.
Will the search engines penalize you for using it? Not yet. But it's probably
going to happen. Given that the main objective of search engine alogrithms are
to prevent manipulation which renders relevancy irrelevant, as it were, surely
this is yet another trick that isn't going to be around for long. I certainly
wouldn't counsel anyone to spend money on cloaking at this point.
