How SEO Began?
Web masters (usually website owners) and content providers began optimizing sites for search engines in the mid-1990s, at first this merely meant you built a website, checked it for spelling errors and then submit it to search engines to be cataloged. Much like a self service library might be run. This was the early World Wide Web.
Once a web master or website owner had submitted a page, or URL, to the a variety of engines they would send a spider to “crawl” that page, extract links to other pages from it, and return information found on the page to be indexed.
The process has now evolved so that a Search Engine Spider downloads a target page and keeps it on the Search Engine’s own server, where a second program, known as an indexer, breaks down the information, extracts a range of elements that compose the page, such as the words it contains, the coding information, META tags, description, title, keywords, link text, and where these are located, and any weight or added significance for specific words as well and all links the page contains, which are then placed into a scheduler for crawling at a later date. The Indexer then provide every element a value according to the search engine algorithm, the mathematical formula used to verify the overall importance of the website in regard to definite search terms.
As site owners started to know the value of having their sites highly ranked and able to be seen in search engine results webmasters started to attempt to know the ways to influence the Search Engines. And this made way to the birth of SEO, Search Engine Optimization. As more users began to search for goods and services online, it was really possible to track how the search results were used. It became obvious that searchers would not often go through many pages of results to find what they wanted. The competition for those high search results became stronger and SEO became and remains very important to website promotion.
Larry Page and Sergey Brin developed “backrub” while they were graduate students at Stanford University, a search engine that relied on a mathematical algorithm to rate the prominence of web pages. The function of the quantity and strength of inbound links which is called the PageRank, is the number calculated by the algorithm. Meaning, some links are stronger than others, or it gives more weight to the PageRank as the contents of the page are more likely to be related to the searcher.
The grad students founded Google in 1998. Google attracted a faithful following among Internet users, who liked the outcome their produced system. Off-page factors such as PageRank and hyper link analysis were taken into account, as well as on-page factors, to allow Google to keep away from the kind of manipulation seen in search engines that only considered on-page factors for their rankings. Although PageRank was more complex, web masters went to work using link building schemes to control search results to their favor. Web masters are paying attention on exchanging, buying, and selling links, often on a massive scale. Some of these schemes, or link farms, involved the creation of thousands of sites for the single purpose of link spamming.
In order to counter the unfavorable impact of link schemes, as of 2007, search engines again had to evolve to consider a wider range of undisclosed factors for their ranking algorithms. Google has since disclosed that it now uses more than 200 different elements to rank pages. Google, Yahoo and Microsoft’s Live Search, are the three leading search engines that closely guard the algorithms they use to rank pages.
