Spam blogs
Spam blogs, sometimes referred to by the
neologism splogs, are
weblog sites
which the author uses only for promoting affiliated websites. The
purpose is to increase the
PageRank of the affiliated sites, get ad impressions from visitors,
and/or use the blog as a link outlet to get new sites indexed. Content
is often nonsense or text stolen from other websites with an unusually
high number of links
to sites associated with the splog creator which are often disreputable
or otherwise useless websites.
There is frequent confusion between the terms "splog" and "spam
in blogs". Splogs are blogs where the articles are fake, and are only
created for spamming.
To
spam
in blogs, on the contrary, is to include random comments on the blogs of
innocent bystanders, in which spammers take advantage of a site's ability to
allow visitors to post comments that may include links. This is used often in
conjunction with other
spamming
techniques including
Sping.
History
The term splog was popularized around mid August 2005 when it was used
publicly by Mark Cuban, but appears to have been used a few times before for
describing spam blogs going back to at least 2003. It developed from multiple
linkblogs
that were trying to influence search indexes and others trying to
Google
bomb every word in the dictionary.
Problems
Splogs have become a major problem on free blog hosts such as Google's
Blogspot
service. Some estimate it may be as high as one in five blogs[1].
These fake blogs waste valuable disk space and bandwidth as well as pollute
search engine results, ruining
blog search engines and damaging bloggers community networking (e.g.
Blogspot's next blog link). Google's search engine uses PageRank, which is very
vulnerable to link flooding, especially from highly weighted bloggers. One splog
clearly states: "Google's run by people who can be bothered to post links on the
internet." Splogs could become a detractor to people using, enjoying and finding
value in the blogosphere. Splogs sometimes choose a name similar to a popular blog. That
way, they can benefit from the occasional incoming link from careless bloggers,
who think they are linking to the popular site.
Benefits
They are good at launching new websites, as Google
caches blogs
frequently. There's rumored to be a secret
webring
called the 'Google brain' that does ethical splogging to improve the ranking of
random good websites.
RSS abuse
Full content RSS
feeds are actually compounding the splog problem
[2]. RSS makes it easy to steal content from genuine blogs. Splog RSS feeds
pollute RSS search engines. Splog RSS feeds are being reproduced and plastered
all over the net.
Defense
Several splog reporting services have been created for good willed users to
report splog with plans of offering these splog URLs to search engines so that
they can be excluded from search results.
Splog Reporter was the first service of this kind. Then came
SplogSpot which actually maintains a large database of splogs and makes it
available to the public via APIs, and
A2B which blocks web server IP addresses that splog URLs resolve to. As well
as automated
attempts to find them. Blogger has implemented a system that can detect
splogs and then force them to take a Captcha
'spell this word' test. Blogger has recently deleted thousands of splogs in
September
[3] and even more in December.
