Engine Optimisation
A Concise History
During the period
of the mid-1990s, the first search engines had begun cataloging the
early form
of the World Wide Web, or more simply, the Web.
Consider the following
terms:
Webmaster - Also
known as the creator of the website
or its author, it is the
person
who is responsible for the upkeep of the website. The typical role of a
webmaster could involve making sure that the web servers, hardware and
software
are performing correctly, designing and redesigning the website,
creating and
revising web pages, answering any questions from users, and monitoring
web
traffic through the site.
URL - In terms of
computing, a URL, otherwise known as a Uniform
Resource Identifier, is a string (or sequence) of
characters (or units
of information) which identifies or characterises a resource (or any
entity
that can be identified) on the Internet.
Spider - A Web
crawler, otherwise known as an ant, bot, worm
or web spider, is a computerised programme that browses the Internet
automatically, and in a structured
manner. Such a process is
referred
to as Web crawling or spidering. It is common for search
engines to use spidering as a method of generating up-to-date data. Web
crawlers
have a primary task of creating a copy of the searched pages which will
then be
processed by a search engine that will classify the downloaded pages in
order
to produce fast data searches. Crawlers also provide website
maintenance tasks,
such as ensuring there are no broken links or checking the validity of
HTML
code.
Indexing – Search
Engine indexing is the process whereby data is collected and stored in
order to
provide for fast and accurate information retrieval. An alternate name,
by
which search engines obtain web pages from the Internet, is Web indexing.
It
was at this time that webmasters and the providers of
website content began optimizing websites with the purpose of making
them more
attractive for search engines when they came to view the sites.
All
that the webmaster had to do was submit the address of
the page, also known as the URL, to the various search engines whose
role would
be to direct a spider to "crawl" that particular page, then extract
links to other pages from it, and finally to return information found
on the
page in order that it may be indexed.
The
process of indexing requires a search engine spider to
download a page and store it on the search engine's own server. At this
point,
a computer program, known as an indexer, extracts various pieces of
information
concerning the page, such as:
All the words that it
contains and where they are located
Should there be any
particular emphasis or weighting for
specific words
All the links the page
contains
At
this point, the data is then placed into a scheduler that
will allocate when the page requires future crawling. The purpose of storing an index is to maximise the
speed and ability to find relevant documents for a search query.
Without an
index, the search engine would scan every document, which would be
impractible.
According
to the industry analyst Danny Sullivan, who is the editor-in-chief of
Search
Engine
Land, the
concept
of search engine optimization more than likely came into prominence
around
1997.
