An Introduction to Search Engines and SEO
Searching for information on the internet would have been an impossible task if not for search engines.
A search engine is a program that has a database and related tools which are used to search the user’s
input or keywords.
Two terms with which people often get confused are search engines and web
directories.
Search engines are operated with the use of algorithms while web directories are upheld by
human editors.
Search engines have an advantage over the web directories as the algorithms regularly
return to the sites and keep track of updates.
As a result, they have the latest information on hand all
the time.
Web search engine stores information about websites that are recovered from their web addresses.
They make use of a Web crawler (also called a spider) which automatically keeps track of the links on
the webpage.
The details of the page are then indexed by using the titles or other fields.
