Top Search Engines by Usage-Other Statistics
Knowing where your users hang out is pretty important as that is where you
want your site to be *hanging out* as well. Ask yourself: budget permitting,
would you rather advertise on a dirt road in the middle of nowhere or on
national television? According to recent statistics, humans tend to do
their searches using the *big three* or as I call them *GYM*; Google, Yahoo!
and MSN. This is why the *we'll submit you to 1000 search engines for $19.95*
services are NEVER a good idea. Concentrate your efforts, monitoring, etc
on GYM. These search engines are the "national television ad" of
the Internet and that's right where you want to be.
