Answers will vary, but should include the main points listed below: Metasearch engines do not search the Web itself; rather they search engines' indexes. By searching more than one search engine's index simultaneously, metasearch engines access more of the Web in a single search. However, metasearch engines often do not search the best search engines, because of the fees such search engines charge. Also, search engines that are busy with too many other searches at the exact moment you conduct your search are sometimes skipped, so results can be inconsistent. Metasearch results are broad, but often not as deep as a single search engine's. Metasearching is a good place to start when you want to check the first few results from several search engines.
