Unlike Google search engine, Meta Search engine do not have its own database. In a returned result, relevant information from various databases are collected together making it convenient for users as they do not need to access multiple search engines.
Subject directories on the other hand makes browsing the easiest and most effective as users can find their way through a hierarchy of topics. However, search results do not go into millions like Google search engine. Hence, the probability of finding what u need or what is relevant to your topic would be lower.
Thus, I did a search on Yahoo directory using the same search query but the number of times the search term appears in the results is the lowest compared to Google and MetaCrawler. The returned searches are places of volcanic eruptions and mostly irrelevant topics like prophecy, alien VS predator.
By using different search facilities, we are open to wider and broader information related to our search topic as the different search facilities may provide us with assorted information. As some search facilities may provide little information relevant to our search topic, by using different search facilities, the chances of finding useful information would increase. This would greatly enhance our resources.
With the use of site feeds, information is organized in a structured format. Hence, reading of blogs and other related sites would be easier. Furthermore, browsing my friend’s blog or any related site would be more effective and convenient!
