Google Panda Update:
"This update is designed
to reduce rankings for low-quality sites—sites which are low-value add for
users, copy content from other websites or sites that are just not very useful.
At the same time, it will provide better rankings for high-quality sites—sites
with original content and information such as research, in-depth reports,
thoughtful analysis and so on".
Basically, Panda updates
are designed to target pages that aren't necessarily spam but aren't great
quality. This was the first ever penalty that went after “thin content,” and
the sites that were hit hardest by the first Panda update were content farms (hence
why it was originally called the Farmer update), where users could publish
dozens of low-quality, keyword stuffed articles that offered little to no real
value for the reader. Many publishers would submit the same article to a bunch
of these.
Google Penguin Update:
The Google Penguin
Update launched on April 24. According to the Google blog, Penguin is an “important algorithm change targeted
at web spam. The change will decrease rankings for sites that we believe are
violating Google’s existing quality guidelines.” Google mentions that typical
black hat SEO tactics like keyword stuffing (long considered web spam) would get
a site in trouble, but less obvious tactics (link incorporating irrelevant
outgoing links into a page of content) would also cause Penguin to flag your
site. Says Google,
"Sites affected by this
change might not be easily recognizable as spamming without deep analysis or
expertise, but the common thread is that these sites are doing much more than
white hat SEO; we believe they are engaging in web spam tactics to manipulate
search engine rankings".
