What is a Search Engine?

A search engine is a website that allows people to enter in keywords and then shows them results for those keywords. They are often used by people who want to know about something, but don’t know where to start their research. Search engines should be optimized so that they show the most relevant information at the top of the list!

Search engines are systems that actually search for information on the internet and then index it so that you can find it more quickly.

There are different types of search engines available depending on what you want to use one for – you might have heard of things like Google, Bing, Yahoo!, and DuckDuckGo!

The most popular search engine by far is Google, but there are many other options out there as well. In this post we will discuss what a search engine is, how they work, and the different types of search engines available to you.

Process of searching:

  • When you type in a search query, your browser sends the request to one of many servers.
  • The server then searches its index for the most relevant pages and returns them to your browser.
  • Your browser then displays the results on your screen.
  • If you click on a link, it will take you to that page and display it in your browser window.
  • You can also use shortcuts like “Ctrl+F” or “Command+F” to find words or phrases within a web page.
  • Search engines is not always accurate because they rely on other websites for their information.

Popular Search Engines

Google

Google is the most popular search engine on the internet. It was created by Larry Page and Sergey Brin, two Stanford graduate students in 1998 who were dissatisfied with existing search engines at that time which relied heavily on keyword matching to provide results.

The indexing process of Google has been focuses around its “PageRank” system since 2001, where a page’s rank will increase over time if it receives links from other pages.

This web-ranking algorithm provides relevance based upon how many people are linking to these sites rather than simply what keywords they contain. To better understand this type of ranking, imagine your website linked to another site about soccer – even though there might not be any mention of soccer anywhere else on your own site you can still be considered relevant to the search term “soccer.”

Bing

Microsoft’s Bing search engine was launched in 2009 and has been steadily growing.

Bing uses a technique called “decision trees” to find the best results for any given set of inputs. The decision tree algorithm is based on probability rather than simply matching keywords, allowing it to provide more useful information about what you are looking for (if not an exact result). It also provides better answers from less popular sources by using algorithms that calculate which websites have the most accurate answer or offer the highest quality content.

DuckDuckGo

DuckDuckGo is a search engine that gathers information from over 400 sources, including Bing and Yahoo. DuckDuckGo uses filters to filter out spam results and avoid showing you links with malware or inappropriate content. It also protects your privacy by not storing any of the personal information it collects about its users (unlike most other popular search engines).
