A search engine searches for documents and then indexes them according to the user's search requests. The term these days mostly refers to web or internet search engines.
For more information
There are many websites that explain the different types of search engines and how to get the best results from searches. These can be found by typing in the words 'search engine information' into a search engine.
Search engines and online businesses
Most search engines do not attempt to validate content or endorse the businesses that are found via searches.
Different search engines use different criteria or policies for indexing sites found through a search.
Some search engines, for instance, include websites in their listings that use keyword advertisements or paid placements. This allows individual websites to pay for a higher ranking in a search results list so that the ranking is not necessarily based on relevance to the search request.
It is worthwhile checking the search engine’s policy when it comes to search results. Such information should be available at the home page of the site.
Businesses using search engines
Most search engine home pages provide advice to online businesses on how to access their services.
