To create your own personal visit counter, copy the cookie function script from Column 8 and paste it in the <HEAD>...</HEAD> portion of your HTML document. Once you do that, you can embed a script that employs the universal cookie functions in your document. Take a look at the following script:

<SCRIPT LANGUAGE="JavaScript">
<!--

// create an instance of the Date object
var now = new Date();
// fix the bug in Navigator 2.0, Macintosh
fixDate(now);
// cookie expires in one year (actually, 365 days)
// 365 days in a year
// 24 hours in a day
// 60 minutes in an hour
// 60 seconds in a minute
// 1000 milliseconds in a second
now.setTime(now.getTime() + 365 * 24 * 60 * 60 * 1000);
var visits = getCookie("counter");
// if the cookie was not found, this is your first visit
if (!visits) {
  visits = 1; // the value for the new cookie
  document.write("By the way, this is your first time here.");
} else {
  // increment the counter
  visits = parseInt(visits) + 1;
  document.write("By the way, you have been here " + visits + " times.");
}
// set the new cookie
setCookie("counter", visits, now);

// -->
</SCRIPT>

Note that this script can be placed anywhere on the page. It prints the number of times the user has visited your site.
