The History of Search Engines
Modern search engines are pretty incredible – complex algorithms enable search engines to take your search query and return results that are usually quite accurate, presenting you with valuable information nuggets amidst a vast information data mine.
Search engines have come a long way since their early prototypes, as our Internet Search Engines History infographic illustrates. From improvements in web crawlers and categorizing and indexing the web, to introducing new protocols such as robots.txt so that webmasters have control what web pages get crawled, the development of search engines has been the culmination of multiple search technologies that developed from different search engines. Alta Vista was the first search engine to process natural language queries; Lycos started strong with a system categorizing relevance signals, matching keywords with prefixes and word proximity; and Ask Jeeves introduced the use of human editors to match actual user search queries,
How Do Search Engines Work?
First of all, let’s ask what is a search engine? A search engine is a program that searches the web for sites based on your keyword search terms. The search engine takes your keyword and returns search engine results pages (SERP), with a list of sites it deems relevant or connected to your searched keyword.
The goal for many sites is to appear in the first SERP for the most popular keywords related to their business. A site’s keyword ranking is very important because the higher a site ranks in the SERP, the more people will see it.
SEO, or search engine optimization, is the method used to increase the likelihood of obtaining a first page ranking through techniques such as link building, SEO title tags, content optimization, meta description, and keyword research.
Google search engines and other major search engines like Bing and Yahoo use large, numerous computers in order to search through the large quantities of data across the web.
Web search engines catalog the world wide web by using a spider, or web crawler. These web-crawling robots were created for indexing content; they scan and assess the content on site pages and information archives across the web.
Algorithms and Determining the Best Search Engines
Different internet search engines use different algorithms for determining which web pages are the most relevant for a particular search engine keyword, and which web pages should appear at the top of the search engine results page.
Relevancy is the key for online search engines – users naturally prefer a search engine that will give them the best and most relevant results.
Search engines are often quite guarded with their search algorithms, since their unique algorithm is trying to generate the most relevant results. The best search engines, and often the most popular search engines as a result, are the ones that are the most relevant.
Search Engine History
Search engine history all started in 1990 with Archie, an FTP site hosting an index of downloadable directory listings. Search engines continued to be primitive directory listings, until search engines developed to crawling and indexing websites, eventually creating algorithms to optimize relevancy.
Yahoo started off as just a list of favorite websites, eventually growing large enough to become a searchable index directory. They actually had their search services outsourced until 2002, when they started to really work on their search engine.
History of Google Search Engine
Google’s unique and improving algorithm has made it one of the most popular search engines of all time. Other search engines continue to have a difficult time matching the relevancy algorithm Google has created by examining a number of factors such as social media, inbound links, fresh content, etc.
As evidenced by the above infographic, Google appeared on the search engine scene in 1996. Google was unique because it ranked pages according to citation notation, in which a mention of one site on a different website became a vote in that site’s favor. This was something that search engines
Google also began judging sites by authority. A website’s authority, or trustworthiness, was determined by how many other websites were linking to it, and how reliable those outside linking sites were.
Google search history can be witnessed by taking a look at Google’s homepage progressions over the years. It’s remarkable to see how basic and primitive the now most popular search engine once was.
