Search Engine Optimization

In today’s net-savvy world, it has become common for any business to have a website which they use mostly for advertising their products and services. With the advent of search engines, it has become even easier for the customers to search for the stuff online. For a website to be successful, its link should land in the first three pages which the search engine brings, and the rank of the page should be high which means many visitors come to the site. This can be achieved by applying search engine optimization, popularly known as SEO. This is a marketing strategy which increases the quality and quantity of traffic flow to a particular website via search engines.

SEO not only affects the search engine results, but also image search, video search and industry specific vertical search engines.

It determines how a search algorithm functions and searches what is popular with people. When a website link is submitted to a search engine, a spider crawls through a page to gather links which lead to other pages and stores those pages on the server of the search engine. The information collected from these pages is sent to the indexer, whose job is to extract information from those pages such as the keywords and their weights, the location of the page and other links that are stored for the spider to crawl in future.

In the beginning, the search engine optimizer algorithms were dependant on the keywords, Meta tags, and index files provided by the Webmaster.

Meta tags provided information about a particular page, but using them for indexing the pages didn’t prove to be successful as some Webmasters added irrelevant Meta tags to increase the number of hits and earn huge ad revenue. They even changed the HTML of the web pages to achieve a good rank for the page. But, this was a case of abuse as it fetched irrelevant pages.

Search engines then began utilizing complex ranking algorithms, which were difficult for the webmasters to manipulate. These provide web surfers with genuine results. The rank of the web page was calculated mathematically by functions using strength and quantity of the inbound links. The higher the rank of the page the more chances it had to be viewed by a person. Later, algorithms were developed which considered various other on-page factors such as rank and off-page factors such as hyperlink. Since the webmasters couldn’t manipulate the page rank, they began exchanging, selling and buying links, which led to link spamming. Numerous sites were even created for this purpose.
