What criteria can be used to differentiate between good and bad traffic on a website?

One way to differentiate between good and bad traffic on a website is by analyzing the behavior of the visitors. Good traffic typically consists of visitors who engage with the content, spend time on the site, and visit multiple pages. Bad traffic, on the other hand, may come from bots, click farms, or other malicious sources that artificially inflate traffic numbers without providing any real value.

// Sample PHP code to differentiate between good and bad traffic

// Check if the visitor's behavior indicates good or bad traffic
function analyzeTraffic($visitor) {
    if ($visitor['time_spent'] > 30 && $visitor['pages_visited'] > 3) {
        return "Good traffic";
    } else {
        return "Bad traffic";
    }
}

// Example usage
$visitor1 = ['time_spent' => 45, 'pages_visited' => 4];
$visitor2 = ['time_spent' => 10, 'pages_visited' => 1];

echo analyzeTraffic($visitor1); // Output: Good traffic
echo analyzeTraffic($visitor2); // Output: Bad traffic
