In
the first half of this year, there has been a lot of SEO-related news
coming out from Google. Google has pushed out many new algorithms, made
many changes to the search result interfaces, penalized many websites
and tactics, as well as sent out many warnings about upcoming penalties
or actions.
All of this was covered in depth on our sister site, Search Engine Land, but a recap is in order for our Marketing Land readers.
Below,
I will summarize the changes in order of Google’s Panda algorithm,
Penguin algorithm, and other algorithm updates and launches. I will
then discuss some of the manual actions taken and then some of Google’s
warnings and statements.
Google Panda Algorithm
Google’s Panda algorithm launched
in February 2011 and has since been at the top of the minds of
webmasters and SEOs. In the past six months, we learned a lot about
Panda. Google recently started to roll out Panda updates over a 10 day
period and promised to not give us confirmations of Panda updates going
forward. Below are some of the stories we covered in the past six
months on this content hungry algorithm.

Google Penguin Algorithm
Google’s Penguin algorithm launched
in April 2012, and while Panda looked closely at content, Penguin went
after links pointing to a page. While Panda’s algorithm impacted a
larger percentage of the search results, i.e., 12%, the Penguin update
was probably felt more by SEOs, but only impacted about 3% of the search
results. We counted four updates to the algorithm since its launch,
but in 2013, Google significantly updated the algorithm calling it Penguin version 2.0.
The previous updates happened as such:
- Penguin 3 on October 5, 2012 (impacting ~0.3% of queries)
- Penguin 4 on May 22, 2013 (impacting 2.3% of queries)
Other Google Algorithm Updates/Launches
Outside
of the big guns, Penguin and Panda, we had many other algorithm and
launches from Google in the past six months. From the PayDay loan
algorithm, to mobile site speed and domain clustering – Google has been
busy working on improving their relevancy and combating spammers. Here
are some of the major changes to the algorithm in the past six months.

Google’s Manual Actions:
Algorithms,
such as those mentioned above, impact a wider base of sites, but
Google also has an army of search quality analysts that patrol the Web
to find sites manipulating their search results and getting by the
algorithm. There is a difference between algorithm and manual penalties,
and below are some of the manual actions Google has taken or promised
to take in the past six months. Some of these impacted huge brands,
while others impacted specific industries or techniques.
