HOW A SEARCH ENGINE WORKS
How a search engine works, how web pages are added to search engine lists
Web Crawler - continually searches the web looking for new pages and recording information they find/browsers the web and keeps an index of what it finds. Run by search engines, these programs ‘visit’ web sites and collect URLs which can be indexed to help with searches. Good for finding new sites.
A web crawler searches around the Internet looking at heavily used servers or popular webpages. The web crawler looks at significant words and notes their location on a page and where they were found. The web crawler also looks at meta tags, titles and sub-titles. This process never stops.
Search Engine - An application accessed over the internet that maintains indexes of web pages; and allows you to use logical operators/key words to find the information you require.
