Exploring Search Engines The Backbone of the Internet

Search Engines - A search engine is a software system designed to search for information on the World Wide Web. It uses algorithms to retrieve and organize data from web pages and other online sources based on a user's query or search terms.

Understanding Search Engines Example - A student wants to learn Machine Learning, so he searches the “Machine learning tutorial” in the search engine. The student gets a list of links that contain the tutorial links of machine learning. A search engine is an internet-based software program whose main task is to collect a large amount of data or information about what is on the internet, then categorize the data or information and then help user to find the required information from the categorized information.

Importance of Search Engine Marketing in the Digital World

In 1994 the first recognized crawler search engine was developed. WebCrawler was the first search engine to provide full text search. In 1994, Brian Pinkerton, a computer science student at the University of Washington, create WebCrawler with a database of 4000 sites. Unlike its predecessors, it let users search for any word in any web page, which became the standard for all major search engines since. It was also the first one to be widely known by the public.. World Wide Web – 1994 Evolution of Search Engines

In June 1995, America Online (AOL), acquired WebCrawler. But just over 2 years later in April 1997 WebCrawler was sold by AOL to Excite. WebCrawler still exists today but it no longer uses its own database to display results. 2018 was the last time the engine had a face lift and new spider logo

AltaVista was launched in 1994 and established itself as the standard among search engines for a number of years. It was the first with its own index. Alta Vista continued to be prominent in the search market for a long time because it used a robot called “Scooter” that was particularly powerful. These days, AltaVista.com redirects to Yahoo!

Lycos came onto the market in the summer of 1994. The function and the principle were ground-breaking, because Lycos not only could search documents, but also had one algorithm which measured the frequency of the search term on the page and also looked at the proximity of the words to each other.

HotBot was launched using a “new links” strategy of marketing, claiming to index the entire web weekly, more often than competitors like AltaVista to give its user far fresher and more up to date results. At the time their claims were that they were the “most complete Web index online” with over 54 million documents in their database.

YAHOO! was founded in 1994 by David Filo and Jerry Yang and was initially a pure web directory. Yahoo was also very prominent in the world of online chat. Before instant messaging services, the 1990s web was full of chat room, with Yahoo chat being on of the most popular options due to their wide choice of subject matter chat rooms.

The name “Backrub” came from how the search engine analyzed “backlinks” pointing to websites to understand their importance for ranking purposes. Page and Brin assembled Backrub using leased servers and parts they bought at discounted prices. It operated on Stanford’s network for over a year, eventually processing around 10,000 queries a day. The Google homepage launched in 1998 with a basic, uncluttered interface showing just a “Google!” logo, search bar and Search button.

Bing was launched by Microsoft in 2009 as the successor to live.com (Live Search) in order to finally be able to compete with Google and has increasingly included social media content since 2012. In October 2010 Bing started been working with Facebook . Bing’s integration with Facebook’s search engine was seen as a potentially important way that Microsoft could compete with Google. Alongside Facebook’s own semi-programmable search queries, users could plug in web searches that would return structured information like the local weather.

DuckDuckGo was developed by Gabriel Weinberg and went live in 2008. This search engine with the unusual name is a combination of a meta search engine and its own web crawler. The search results are delivered from over 400 external sources, such as Bing, Yandex, Yahoo Search BOSS or Wikipedia. In addition, there are the results of our own web crawler called DuckDuckBot , which regularly crawls the web itself for information. According to Wikipedia, on November 13, 2017, there were more than 20 million searches in one day via DuckDuckGo.

The Russian search engine Yandex ( Яндекс ) was founded in 1997 and, it is a company based in Amsterdam and has its operational headquarters in Moscow. There are also branches in Belarus, Switzerland, the USA, Turkey and Germany.

Baidu is the leading search engine in China. Baidu is the most popular search engine in China with a staggering 84.26% of the market share. Bing hold 6.65% and Google only see a 1.33% share of the Chinese market.

Ecosia GmbH was founded on December 7th, 2009 and is based in Berlin. Ecosia search results are provided by Bing and no personally identifiable information is stored on Ecosia. They claim they use the search technology of the search expert Bing – and make it even more efficient with their own algorithms.

Impact of Search Engines Search engines have become integral to our daily lives, profoundly influencing how we access and process information. They employ crawling methods to discover content, using links as signposts to navigate the vast expanse of the web. The effectiveness of search engines is critical, as they shape our understanding of the world by determining the information we encounter. Their architecture can significantly affect the results they produce, impacting everything from environmental footprints to societal dynamics. Search engines are evolving with AI enhancements, promising to revolutionize user experience through improved storytelling and search result relevance. As such, they hold a powerful role in shaping society and the dissemination of knowledge

Future Trends in Search Engines As voice recognition technology continues to improve, expect search engines to prioritize results optimized for conversational language and natural responses. Businesses need to ensure their websites and content are voice-friendly to stay ahead of the curve.
