Dazu bearbeitet man die Datei statistics.module im Verzeichnis modules/statistics. Hier ersetzt man die Funktion statistics_exit() mit folgendem Code. Anschließend wird der Zähler nicht mehr erhöht, wenn ein Administrator oder der Autor eines Nodes den entsprechenden Artikel aufruft.

function statistics_exit() {
  global $user, $recent_activity;

  drupal_bootstrap(DRUPAL_BOOTSTRAP_PATH);

  if (variable_get('statistics_count_content_views', 0)) {
    // We are counting content views.
    if ((arg(0) == 'node') && is_numeric(arg(1)) && arg(2) == '') {
      // A node has been viewed, so update the node's counters.
      // exclude admin & node author
$nid = arg(1);
$node = node_load($nid);
$node_author = $node->uid;
if (!user_access('administer nodes') && $user->uid!=$node_author) {
          db_query('UPDATE {node_counter} SET daycount = daycount + 1, totalcount = totalcount + 1, timestamp = %d WHERE nid = %d', time(), arg(1));
         // If we affected 0 rows, this is the first time viewing the node.
          if (!db_affected_rows()) {
        // We must create a new row to store counters for the new node.
        db_query('INSERT INTO {node_counter} (nid, daycount, totalcount, timestamp) VALUES (%d, 1, 1, %d)', arg(1), time());
    }
         }
    }
  }
  if ((variable_get('statistics_enable_access_log', 0)) && (module_invoke('throttle', 'status') == 0)) {
    // Log this page access.
    db_query("INSERT INTO {accesslog} (title, path, url, hostname, uid, sid, timer, timestamp) values('%s', '%s', '%s', '%s', %d, '%s', %d, %d)", strip_tags(drupal_get_title()), $_GET['q'], referer_uri(), $_SERVER['REMOTE_ADDR'], $user->uid, session_id(), timer_read('page'), time());
  }
