What are Search Engines?
Search engines are large databases of web page files that have been grouped and assembled together by machine.
How do Search Engines work?
Search engines employ ‘spider’ or ‘robots’ to crawl through the web space from link to link, identifying and recording web pages. Sites with no links and other pages may be entirely missed. Once these spiders get to a web site they index most of the publically available words on that site.
Web page owners can submit their site URL’s to the search engines for ‘crawling’. These will eventually be added to the search engine databases. So, whenever you conduct a search on the web you are essentially asking the engine to scan it’s database of sites to match your keywords and phrases. This is how search engines work.
