Answer 1

You can either change the User Agent in the HTTP headers, or look for bot like activity, such as a very high frequency of hits over a wide range of pages coming from a single ip address (though you might see that with a Proxy Server too). You can also look for hits on Robots.txt and assume that other visits within the same session where also from a robot.

In reality there is no sure fire way of doing it, as sophisticated robot writers could pretend to be browsers.

Answer 2

Time can be good measurement of whether a visit was a human or a bot.

If you set a time-out or delay on the JavaScript which tracks the user visit to execute after 1 or 2 seconds. Most humans will visit a page for at least that time (even if they don't like it) whereas a bot should be able to scan and move on in that time.

Just a thought.

Answer 3

if(strstr(strtolower($_SERVER['HTTP_USER_AGENT']), "googlebot"))
{
    // Google Bot visits you
}

This is an PHP example of finding out, if the visitor is GoogleBOT.
