Search Engines and Internet Research
Their answers are usually very different. For example, the first page results of Google and Yahoo often have only a couple of results in common.
If you are searching for an "answer," or general information, one search engine is fine. But for more in depth research, perhaps about you, your company, or someone you're considering doing business with (or maybe even dating!), you need to use several search engines.
This was slammed home recently after I noticed that people kept coming to demop.com by searching on "fun persuasion speech topics" - apparently a popular search. I'm not in the first couple of pages of Google results, but My Blogging for Business speech is the #1 hit on Yahoo! Microsoft's search http://search.msn.com/ shows it as the #2 hit and AOL's search http://search.aol.com/ doesn't show it on the first few pages.
Google, Yahoo!, etc. are examples of general search engines. They will find blog information also, but it's worth checking blog specific search engines such as Technorati, Feedster, and Google Blog Search as well.
Don't be surprised if an interesting piece of information shows up in only one search engine, and NONE of the rest!!
