You can--you need to check the signature of the visiting client and
determine whether it is a spider (for example, Google indexers are called
"googlebot"s). This is in $_SERVER['HTTP_USER_AGENT']. Here's a thread on
the subject:

You can also use the browscap-related functionality to extract more
information from the user-agent string, although this is not always 100%
reliable:

Remember, however, that most search engines shun this practice and may drop
your site from their indices if you adopt it.
