What is SEO?
SEO or Search Engine Optimization is known as a process of maximizing a particular website’s visitors. This is done by making certain that the site appears high and more frequent on the result list returned by a search engine. This is also known as organic or earned result and SEO (Search Engine Optimization) may target different kinds of searches. These different searches include academic research, image research, video research and local search along with industry-specific vertical search and news search engines. Search engines such as Google show the content rankings based on what the search engine considers most relevant for its users.
THE HISTORY OF SEARCH ENGINE OPTIMIZATION
It began in the mid-1990s, when the content provider and webmasters started optimizing sites for search engines as the web was being catalogued by the first search engines. The process was as such that all the webmasters needed to submit the page’s URL or address to the many engines, which sent a ‘spider’ to ‘crawl’ that page while extracting from it the links, to other pages, and on that page, the information found had to be return and then indexed. A search engine spider downloads the page and stores it on to the server of the search engine, after which the next program which is known as the indexer extracts all the information available regarding the page like the words and the location of those words along with specific words and all the links contained by the page. All of this information is then placed for crawling, into a scheduler for a later date.
Soon after, site owners started to acknowledge the value of having their websites ranked highly while being visible in the search engine results. Then it created an opportunity for black hat and white hat SEO practitioners. However the phrase “search engine optimization” had came into use in around 1997, according to Danny Sullivan who was an industry analyst. Bruce Clay was amongst the first people to make the term Search Engine Optimization popular, and Danny Sullivan credits him for that as well.
The search algorithms’ early versions relied exclusively on information provided by webmaster; information such as index files in engines and the keyword meta tag. Meta tags provide a guide to every page’s content and so using the meta data to index pages was then found to be extremely unreliable since the webmasters keyword choice in the meta tag could have been an inaccurate representation of the actual content of the site. Due to this the early search engines suffered from inconsistency, inaccuracy and manipulation in ranking. Hence to provide improved and fair results to its users, the search engines had to improvise. Basically the success of a search engine is determined by the ability of the search engine to produce relevant results to any given search and irrelevant searches could lead users to find other search engines. Thus the search engines developed a rather more complex algorithm analyzing additional information that the webmasters would find difficult to manipulate.
