Lesson 3

Still with me, Wendi?
	Do I have a choice, Will? Obviously, you're not going to the mall with me until you make me a World Wide Web expert!
In that case, let's see how much you remember from Lesson 2. First of all, how does a directory search engine work?
	A directory search engine employs people who search the Web to find quality web sites. They then organize these sites into categories on the search engine's server.
Very good, Wendi! Now tell me about keyword search engines.
	Keyword search engines use spiders, which are software programs, not bugs, to find web pages containing the keyword you're searching for. The spider then brings back those pages and saves them on the search engine's server.
Excellent, Wendi. You can pay attention and whine at the same time!
	Very funny, Will. I also learned that Yahooligans and Yahoo are popular directory search engines. You promised that you'd teach me about keyword search engines, too.
And I always keep my promises. Here we go!
