What is a Search Engine Crawler?

A Search Engine Crawler is a computer program that visits websites, parses the website's content and stores this information in the search engine's database. Search Engines like Google re-visit your website anywhere from every few days to every few weeks in order to pickup any changes you have made to your website content.

What are some Crawler-Based Search Engines?

All the major search engines use crawlers to gather information about the Internet. Google, Bing and Yahoo are the largest search engines that use crawlers but this is just the tip of the ice-berg. There are literally thousands upon thousands of Search Engine Crawlers scouring the Internet any given second of the day.
