What is SEO?
Nowadays the internet has become an effective new media for anyone and specially
for businesses and consumers alike. It is playing a major role in all walks of life
like online shopping, paying bills, internet banking and more. The business vendors
are also depending on the internet to increase sales, increase visibility and brand
themselves like never before. People have made their online presence through websites.
Day by day people are more and more dependent on search engines as a way to access
the vast amount of information available.The search engines, for their part, were
battling it out amongst one another to have the largest databases and to provide
the most relevant search results for any query.
To display relevant results from its database, search engines follow an algorithm
based on content links and other factors. To tell search engines that a particular
keyword is relevant to a particular industry, webmasters aim to make their sites
to be search engine friendly with some of their algorithmic factors. As this practice
developed it became known as “SEO”.
or in other word,
Search engine optimization (SEO) is the process of improving the volume and quality
of traffic to a web site from search engines via "natural" ("organic" or "algorithmic")
search results. Usually, the earlier a site is presented in the search results,
or the higher it "ranks," the more searchers will visit that site. SEO can also
target different kinds of search, including image search, local search, and industry-specific
vertical search engines.
Overview of search engines algorithms
Every search engine follows its own algorithm for ranking and showing results in
their searches. And every search engine has an automated program called “robots”
that spider the web and index the pages of a website. They are programmed to follow
virtually any link and as they go they index all the data on that page.
When the data is passed back to the database it is analyzed for various factors
such as keywords, titles and inbound links.
The search engine algorithm is then
used to determine the ranking of a site for a particular keyword. Though search
engines consider several factors for ranking in their own search, it had become
a critical issue to webmasters to optimize a single site for one search engine –
because the cloaking was no longer working. Hence webmasters and SEO specialists
did some research and come up with some common factors that worked for all search
engine rankings and defined them as the “SEO basic factors”.
Usually search engines consider several factors to show a site in top position of
their searches. For example the top most well known search engine Google considers
650 factors to rank a site in the top position of its searches. But it gives certain
weight-age to each factor and based on the average weight-age of each factor it
ranks the site on top position in its search for a particular phrase.
