What are the potential pitfalls of tracking banner clicks on your own server?

One potential pitfall of tracking banner clicks on your own server is the potential for inaccurate data due to factors such as ad blockers or users disabling cookies. To solve this issue, you can implement a client-side tracking solution using JavaScript to track clicks and send data to your server asynchronously. 

// Example of client-side tracking using JavaScript
<script>
document.getElementById('banner').addEventListener('click', function() {
    fetch('track-click.php', {
        method: 'POST',
        body: JSON.stringify({banner_id: 123}),
        headers: {
            'Content-Type': 'application/json'
        }
    });
});
</script>
