Consider Back Links Popularity Votes

Consider Back Links Popularity Votes

Quintessentially, Google calculates the importance of a page by the number
of such ‘votes’ it receives. Not only that, Google also assesses the
importance of the pages that are involved in the voting process.
Consequently, pages that are themselves ahead in ranking and are
important in that way also help to make other pages important. One thing
to note here is that Google’s technology does not involve human intervention
in anyway and uses the inherent intelligence of the internet and its
resources to determine the ranking and importance of any page.

Hypertext-Matching Analysis: Unlike its conventional counterparts, Google
is a search engine which is hypertext-based. This means that it analyzes all
the content on each web page and factors in fonts, subdivisions, and the
exact positions of all terms on the page. Not only that, Google also evaluates
the content of its nearest web pages. This policy of not disregarding any
subject matter pays off in the end and enables Google to return results that
are closest to user queries.

Google has a very simple 3-step procedure in handling a query submitted in
its search box:

1. When the query is submitted and the enter key is pressed, the web
server sends the query to the index servers. Index server is exactly
what its name suggests; it consists of an index much like the index
of a book which displays where is the particular page containing the
queried term is located in the entire book.
2. After this, the query proceeds to the doc servers, and these servers
actually retrieve the stored documents. Page descriptions or
“snippets” are then generated to suitably describe each search
3. These results are then returned to the user in less than a one
second! (Normally)

Approximately once a month, Google updates their index by recalculating
the Page Ranks of each of the web pages that they have crawled. The period
during the update is known as the Google dance.
