Metacrawlers and Metasearch Engines

Metacrawlers and Metasearch Engines By Chris Sherman, Search Engine Watch, Mar 23, 2005 Unlike search engines, metacrawlers don't crawl the web themselves to build listings. Instead, they allow searches to be sent to several search engines all at once. The results are then blended together onto one page. Below are some of the major metacrawlers.

this site is a mother lode!

Great site to research various award winning search engines.Also some of the top searc engines that are used.

Metacrawlers and metasearch tools don’t crawl the web and build indexes like search engines. Instead, they send searches out to multiple search engines at the same time and compile the results for you. These tools are great for testing out your search keywords and gathering more information to continue searching.

Web databases are considered “invisible” because the information they contain is not searchable by typical web search engines and crawlers. That is because these tools are databases NOT web pages and sites. However, they are rich in information and should not be overlooked.
