signals.
8. Payday
Loan:2013
It's a search filter that targets
"very spammy queries" that are
frequently associated with spam
-- often for payday loans,
accident claims, and other
insurance-related sites.
10. ** February 2014: Page Layout #3
In February, Google refreshed their Page Layout algorithm,
also known as "Top Heavy," which dings sites that load too
many ads above the fold. This smaller update is meant to
improve user experience -- users want to see the content they
were looking for right away when they click on a search result,
and Google heard them loud and clear.
11. **May 2014: Panda 4.0, Payday Loan 2.0
In May, Google released a major update to its Panda algorithm, and a smaller one
to its Payday Loan algorithm.
1.Panda 4.0: Google announced the rollout of its major Panda 4.0 update to help
small businesses and websites that create great content do better in Google
search results. Search Engine Land called this change a "softer and gentler" Panda
algorithm that specifically helps out smaller businesses with shallower pockets.
2.Payday Loan 2.0: The details of the Payday Loan 2.0 update are a little fuzzy,
but Google did release the update to specifically target "very spammy queries."
Google told Search Engine Land this update was an international update and
affected different languages to different degrees.
12. ** June 2014: Payday Loan 3.0, Authorship Photo Removed
.payday loan 2.0 targeted specific sites while 3.0 targeted spammy queries
Authorship Photo Removed: Google decided to drop Authorship photos from
most search results, frustrating marketers everywhere. Instead, authors' names
would be linked to their Google+ profiles, without including circle count.(this was
because it decluttered search results, particularly for mobile users )
13. **July 2014: Pigeon 1.0
The changes are meant to help users find "more useful, relevant, and accurate
local search results that are tied more closely to traditional web search ranking
For example, if you search for "chicago hotels," the search results favor URLs from
sites like Hotels.com, Travelocity, and Kayak, while individual hotels' websites
don't show up until page two.
14. **August 2014: Authorship Removed + HTTPS/SSL As a Ranking Signal
1.This move meant Google would no longer track the rel=author tag data.
**HTTPS/SSL As a Ranking Signal: With the update, adding a SSL 2048-bit key
certificate on your site -- what Search Engine Land calls "going HTTPS" -- began
giving websites a small ranking benefit.
15. **September 2014: Panda 4.1
In September, Google released the 27th version of its Panda Update that will
make the search filter more precise to better identify low quality content and
therefore allow more small and medium-sized sites that generate high quality
content to rank better. Although this is a much smaller change than Panda's May
2014 update, it still shows Google's listening to user feedback and doing what it
can to reward smaller sites putting out good content.
