History And Evolution Of SEO

SEO

Search Engine Optimization (SEO) is the task of influencing the online visibility of a website or a web page in a web search engine's results. It can be boiled down to 3 core elements crawling, caching and indexing for publishing the results. Crawling basically means following a path. SEO begins with crawl experience of Google bot, for example, crawls our site, details of which are recorded in a file within our server log files. Indexing is the process of adding web pages into Google search depending upon which meta tag you used(index or no-index). Caching helps you to improve the load time of your web pages and thus optimize your site for the search engines.

SEO practices can be broadly classified into two, ie, White hat and Black hat SEO. White hat SEO refers to the most genuine practices to gain higher page rank. They strictly stick into on to the Googles guidelines for SEO. Black hat SEOs look for loopholes in Googles algorithm in order to rank higher in the search engines.

SEO techniques adopted include On Page Optimisation and Off Page Optimisation. On page optimisation refers to the activities carried out in the page which is to be published. This activities helps in giving high ranking in the search engine result pages. Off page optimisation activities are done on a page after it become live on the web. 

Where did SEO begin, and how did it become so darn important . Let us step back in time and try to unravel the story.

There is no evidence that Dr. Bush's article went into bringing forth of the search engine, but it would have planted a seed in the minds of tech heads of 90's.
