4. Google PANDA
 Launch date : February 24,2011
 Hazards: Duplicate, plagiarized or thin content; user-generated
spam, keyword stuffing.
 Panda assigns a so-called “quality score” to web page; this score
is the used as a ranking factor. Initially Panda was a filter rather
than part of Google’s ranking algorithm, but in January 2016, it
was officially incorporated into the core algorithm. Panda rollouts
have become more frequent, so both penalties and recoveries
now happen faster.

5. Google PENGUIN
 Launch date : April 24, 2012
 Hazards: Spammy or irrelevant links; links with over–optimized
anchor text.
 Penguin’s objective is to down-rank sites whose links it deems
manipulative. Since late 2016, Penguin has been part of Google’s
core algorithm; unlike Panda, it works in real time.

6. Google HUMMING BIRD
 Launch date : August 22, 2013
 Hazards: Keyword stuffing; low-quality content
 Hummingbird helps Google better interpret search queries and
provide results that match searcher intent ( as opposed to the
individual terms within the query)
 While keywords continue to be important, Hummingbird makes it
possible for a page to rank for a query even if it doesn’t contain
the exact words the searcher entered.

7. Google PIGEON
 Launch date : July 24, 2014 (US); December 22, 2014 (UK,
Canada, Australia)
 Hazards: Poor on and off-page SEO

an important part. The update created closer ties between the
local algorithm and the core algorithm: traditional SEO factors are
now used to rank local results.

8. Google MOBILE
 Launch date : April 21, 2015
 Hazards: Lack of a mobile version of the page, poor mobile
usability

optimized for mobile are filtered out from the SERPs or seriously
down ranked.

9. Google RANK BRAIN
 Launch date : October 26, 2015
 Hazards: Lack of query-specific relevance features; shallow content;
poor UX
 Rank Brain is part of Google’s Hummingbird algorithm. It is a
machine learning system that helps Google understand the meaning
behind queries, and serve best-matching search results in response
to those queries.
 Googles calls Rank Brain the third most important ranking factor.
While we don’t know the ins and outs for Rank Brain, the general
opinion is that it identifies relevance features for web pages ranking
for a given query, which are basically query-specific ranking factors.

10. Google POSSUM
 Launch date : September 01, 2015
 Hazards: Tense competition in your target location
 The Possum updated ensured that local results vary more depending
on the searcher’s location. The closer you are to a business’s
address, the more likely you are to see it among local results.
 Possum also resulted in greater variety among results ranking for very
similar queries like “Dentist Denver” and “ dentist Denver co.”
 Interestingly, Possum also gave a boost to businesses located
outside the physical city area.
