For you newbies, going back to what @skoh said about be as unique as possible. Here is a oldie from Eli written in 2006 about proxy servers.
So I’d like to use this post to announce that I am officially selling
out. At the moment Blue Hat SEO is the only site on the internet
dedicated to the art of advanced SEO. However I have gotten lonely of
writing to advanced audiences and would like to start drawing the
attention of beginnner SEOs. So instead of teaching advanced ways of
manipulating proxy servers I’m just going to explain what they are in
plain english. So from now on please expect these kinds of newbie posts
on Blue Hat SEO because that is all you are going to get. Sorry, but I
wouldn’t of had to do this if more people had clicked on that big donate
button.Definition of a proxy server–A
server that acts as an intermediary between a workstation user and the
Internet so that the enterprise can ensure security, administrative
control, and caching service. A proxy server is associated with or part
of a gateway server that separates the enterprise network from the
outside network and a firewall server that protects the enterprise
network from outside intrusion.
Basically a proxy server is a computer someone sets up that works as a
middleman between you and other websites. In other words when you go to
a website, first your computer goes to the proxy server and says hey I
want to go to www.google.com. Then the proxy server goes to google.com
and downloads the page. The proxy server then sends the page to you. So
in a sense you download only from the proxy server and the proxy server
downloads what you ask.This has several benefits. Security is the biggest. Large corporate
networks can track and watch what everyone in the network is going to.
It provides a great deal of control because the proxy server can first
retrieve the page and easily block it, should the need arise. Blocking
other web addresses on a proxy server is easy. The other benefit comes
from “anonymous proxies.” This popular form of proxy never passes your
ip address. Intead it uses the ip address of the proxy server. So people
don’t know who you are.How Are Proxy Servers Useful To Web Spammers?There
are some great sites on the Internet that allow you to download large
lists of public proxy servers. These are servers that allows anyone to
connect to them and use them. This creates a huge advantage because then
you can fake it so it looks like you have TONS of different IP
addresses. It makes you much less traceable when you are spamming. It
also allows you to look like you are different users. So the places you
are spamming and link bombing can’t identify a single person making all
these accounts or posts on their site.
Since I plagiarized this post a bit here are some sites that have
some more information on Proxy Servers. If you aren’t familiar with them
definitely do some research and find out as much as you can. They are a
very useful thing to know about.What Is A Proxy Server-Wediopedia
Proxy Servers-Wikipedia
Firewall and Proxy Server HOWTO-TLDPSo I know a few of you just read this whole thing and are like What
the fuck! Wow, Eli really did sell out didn’t he? I know I know, writing
a little tutorial on what a proxy server is definitely is not advanced
and for most experienced SEOs it should even be common knowledge.
Perhaps there is something else going on here. Maybe I just wrote this
because I got a new post coming out that’s going to knock your proxy
loving world on its ass and I just had to get this information out of
the way and into a reference mark so it wouldn’t pollute the real
information with beginner stuff. There may even be a little something
for the white hats in the possible upcoming post, or perhaps I really
did just sell out
