What are the potential pitfalls of using a custom visitor counter script compared to using Google Analytics?

Potential pitfalls of using a custom visitor counter script include inaccurate tracking due to coding errors, lack of real-time data, and potential security vulnerabilities. Google Analytics, on the other hand, provides more reliable and comprehensive tracking, real-time data, and is maintained and updated by Google to ensure security. 

// Example of implementing Google Analytics tracking code in PHP

<script async src="https://www.googletagmanager.com/gtag/js?id=GA_TRACKING_ID"></script>
<script>
  window.dataLayer = window.dataLayer || [];
  function gtag(){dataLayer.push(arguments);}
  gtag('js', new Date());

  gtag('config', 'GA_TRACKING_ID');
</script>
