Blocking the Annoyance of Trackback Spam
Trackback is one of a few
methods a used by webmasters and bloggers to keep up with who is commenting on,
linking, and referring to their content.
It was originally created by Six Apart and first implemented into
blogging software in August of 2002.
Since then, trackback has become integrated with most blogging tools and
is used rather frequently in the promotional efforts of several ambitious
bloggers.
Understanding trackback
Trackback is actually a
feature used in many content management systems. A blog or another type of CMS driven site
will consist of various functions that allow visitors to interact by making
comments on web pages or by submitting trackback links to their site. Some of the programs making use of these
functions include Community Server, Blogspot, Typo, Wordpress, and Six Apart's
popular creation, Movable Type.
The spam vulnerabilities of trackback
Though the trackback
feature may be great for legitimate users, it is also one that has become
widely abused by millions of conniving spammers. Both trackbacks and comment fields can be
compromised and typed in by robot programs.
This enables them to serve as a viable platform for a high amount of
spam traffic.
Comments are a basic
feature on any blog; this is how the user receives feedback on their
postings. They can be enabled, disabled,
or assigned a certain criteria indicating just who is able to leave comments
and how they are able to do it. Users
can also add links for their website just as you would any kind of text. So when the search engine spiders comb your
site, it is a great chance that the links in your comment boxes will be
detected and possibly receive a quality ranking - free promotion for your regular
visitors and the spammers who have invited themselves into your community.
The concept behind
trackbacks is even simpler. On a website
you may find an area that reads, "Trackback for this URL," which will be
followed by the corresponding link. Most
of the blogging software on the market allows users to send a trackback because
it aids the webmaster by notifying them when others have written something
about their content. When it has been
received, the software will automatically create a link on the web page
referring to the trackback. This helpful
procedure provides great motivation for individuals looking to clutter your
site with trackback and comment spam. It
provides the spammer with a cost-effective means for promoting their products
or services.
Fighting trackback spam
The major search engine
companies recently collaborated and devised a solution to the evolving problem
of trackback and comment spam. Together
they concluded that if a search engine spider detects links that carry the attributes
of spam, the link will not be regarded as popular and stands little to no
chance of receiving a high rank. When
totally implemented, this technique has the ability to completely falter the
efficiency of trackback and comment spam.
Unfortunately, many content management systems are not configured to
these rules, continuously leaving an open window of opportunity to the millions
of spammers freely roaming in cyberspace.
