Q: What is the basic difference between
a search engine and a directory?
A: "Search Engines are sites that are run
completely by computers (bots/spiders)
while directories are sites that are managed
mostly by humans."

Meta Search Engines are search engines
that get their content from other search engines.
You can't actually submit to them
but it is worth knowing about them.
Some Meta Search Engines:
· www.metacrawler.com
· www.megaspider.com
· www.dogpile.com
· www.mamma.com

These are some of the best-known directories:
· www.yahoo.com - Fees for commercial sites.
· www.dmoz.org - Free
· www.looksmart.com - All Fee based
· www.goto.com - Pay per click model

A "referrer" site is the address of the page your
visitor was looking at before he/she came to your site.

You can look up the referrer sites in your sites
statistics to find where you or your Webmaster
need to focus.
