Search Engine SEO
Search engine SEO is a technique of search engine marketing. Search engine optimization (SEO) is a process that improves the number and quality of visitors to a web page. It is done by ranking high in search engines’ search results. If a web site comes on top of search results that website will be visited by more number of visitors. It is vital for a site to get top position in order to direct more visitors to the site, as many of them pay no attention to visit every page of search result. Search engine SEO ensures that a website is available to search engines.
Search engine SEO was introduced in the 1990s. Search engines use programs called “spiders” that crawl a web page and collect necessary data. This data contains the contents on the web page and some codes used to build the page. The contents and basic codes that the spiders search for on a page mainly consist of recommended articles, article archives, discussion forums, reports and books.
Articles that attempt to explain the key concepts of the topic given are called recommended articles. These articles can be opened in a new window. Article archives contain a record of thousands of search engine articles. Article archives places articles by date and this helps the visitor to get the newest information. Discussion forums include the page element on discussion. Books and reports that cover the page element being discussed is included it they are available.
Formerly webmasters themselves used to supply information about the pages to the search engines. Meta tags provided by them directed the users to the contents of web pages. But this was found to be defective since webmasters mistreated Meta tags by adding keywords that is not needed in the contents of their pages. This was done in order to wrongly increase page impressions for their websites and so increase their Ad revenue.
Mistreatment of meta tags by webmasters made search engines to develop more complex ranking algorithms by including additional factors for instance text within the title tag, domain name, HTML tags, file names, term frequency, URL directories, keyword proximity, keyword adjacency, keyword sequence, all attributes for images, web content development, text within NOFRAMES tags and sitemaps. These factors were also in charge of webmasters. Hence search engines continued to undergo abuse and ranking manipulation. This led to the introduction of a new reliable search engine called Google.
Google applies the PageRank concept to assess web pages. PageRank algorithm of Google assesses the importance of web pages based up on the incoming links. With the efficacy of PageRank algorithm, Google became one of the most dependable and popular search engines.
