1. Tagging
 A tag is a non-hierarchical keyword or
term assigned to a piece of information (such as
an Internet bookmark, digital image, or computer
file).
 Tagging was popularized by websites associated
with Web 2.0 and is an important feature of many
Web 2.0 services.

2.  Labeling and tagging are carried out to perform
functions such as aiding in classification and
indicating online identity.
 They may take the form of words, images, or other
identifying marks.

3.  In 2003 social bookmarking websites like Delicious, provided
a way for its users to add “tags”
 Delicious also provided browseable aggregated views of the
bookmarks of all users featuring a particular tag.

7.  The success of Flickr and the influence of Delicious
popularized the concept, and other social
softwarewebsites – such
as YouTube, Technorati, and Last.fm – also implemented
tagging. "Labels" in Gmail are similar to tags.

8. Tag clouds
 Websites that include tags often display collections of tags
as ”Tag clouds”
 A tag cloud (word cloud, or weighted list in visual design)
is a visual representation for text data, typically used to
depict keyword metadata on websites, or to visualize free
form text.

9.  Over-saturation of the tag cloud method led to a noted
decline of usage among these early adopters.

10. Folksonomy
 A folksonomy is a system of classification derived from the
practice and method of collaboratively creating and
managing tags to annotate and categorize content
 Some websites include tag clouds as a way to visualize tags in
a folksonomy. A good example of a social website that utilizes
folksonomy is 43 Things.

 Search engine optimization (SEO) is the process of
improving the visibility of a website or a web page in
search engines.
 The more frequent a site appears in the search results
list, the more visitors it will receive from the search
engine's users.

14.  Search Engine Optimization can be done using
different methods.
1) Getting indexed.
