Most of the websites use tools like Google Analytics or chat widgets like Crisp or Intercom.

Though they have a purpose but they affect the load time of your website which affects the SEO score. You can check the same on Google Lighthouse.

The effective way to solve this is by delaying the script load by 3-5 seconds.

Here's a sample script to get it done.

    <script>
        setTimeout(function () {
            // Your script goes here.
        }, 3000);
    </script>
