This article provides an overview of search engines and a list of the best search engines. An internet search engine is a searchable online database of internet resources, websites and information. A typical web search engine has several primary components:
- Search engine software
- Spider and index software
- An index (the database)
- A relevancy algorithm (rules for evaluating and ranking content)
Search engines are also known as: web search engines, internet search engines, search websites, search directories, etc.
How are Search Engines Used?
Each day, search engines are used to process billions of queries from millions of people all over the world. People use their computer, laptop, tablet, and mobile devices to submit keyword queries to their preferred search tool. In addition, artificial intelligence (AI) devices such as Amazon Echo, Google Home and Apple Siri submit queries based on user voice commands.
The results that are provided in response to keyword queries depend on the device being used. In most cases, such as with computers and mobile devices, the results are provided on a page in a list format, with the most closely matched content being listed first. Most lookup tools provide a hyperlink to the website along with a brief description or blurb of text to describe the result. Results can usually be viewed in different categories, such as web pages, images, videos, news and other types of files.
In some cases, as with Google’s results, the answer is provided on the results page itself, saving the user the extra step of clicking through to the website. When questions are submitted to AI devices, the response comes back in a spoken format. Unlike web directories, which are maintained by human editors, search engines operate using an algorithm or are a mixture of algorithmic and human input.
