site which contains Unique contents are started to get on to the top
position in google search results. And the sites which have low quality
contents [spam , copyright , full of images] are started to fell down in
ranks...
If panda records about poor quality content then your site will never
be at top and of-course the sites traffic will drop down... Google says
that , if you need to recover from panda attack your site's poor quality
content should be "removed, removed or it should not be indexed with
google".

8.  “Hummingbird” is the name of the new search
platform that Google is using as of September 2013, the
name comes from being “precise and fast” and is
designed to better focus on the meaning behind the
words. Read our Google Hummingbird FAQ here.
 Hummingbird is paying more attention to each word
in a query, ensuring that the whole query — the whole
sentence or conversation or meaning — is taken into
account, rather than particular words. The goal is that
pages matching the meaning do better, rather than
pages matching just a few words.
 Google Hummingbird is designed to apply the
meaning technology to billions of pages from across
the web, in addition to Knowledge Graph facts, which
may bring back better results.

9.  Good Content With Strong Backlinks May No Longer
Be Enough

 Don’t Play Link Jeopardy
 Continue To Focus On Quality
 Authorship, Authorship, Authorship
 Know Your Options — And Use Them!

and useful for local search results, and allowing local
search results to be user-friendly and functional as a
traditional web search is. Users will able to see these
changes when they will search specific for local
information. This information will appear differently
in a standard web search as well as on Google Maps.
 The Pigeon update does more to gather information for
Google’s Knowledge Graph as well as recognize
similar keywords within a local search function. This
algorithm update also does more to ensure that a
company’s local listing is active and correct. Be sure to
check for broken links, correct phone numbers, and
spelling in your Google Local listing.

12.  Black hat SEO is often referred to as unethical
SEO. Some of the techniques and strategies
used in black hat SEO consists of doorway
pages, keyword stuffing and invisible text.
Black hat SEO depends on trying to trick search
engine algorithms into believing them to be
credible sites. People use black hat SEO when
they want to get quick results without
considering the consequences.
