Drift Custom Chatbots turn interest into pipeline by pre-qualifying visitors then offering and scheduling a meeting with sales. But it is annoying to have it in mobile resolution. To disable the Drift chatbot in mobile, we can read the width of the device and if that is greater than 520px then we can allow to include the drift code snippet.

                  var device_width = window.innerWidth, screenType;
                  if (device_width <= 520) { screenType = "mobile"; } else if (device_width <= 820) {
                    screenType = "tablet"; } else { screenType = "desktop";  }
                  if(screenType != 'mobile') {
                    //ADD YOUR DRIFT CODE SNIPPET
                  }, 5e3);
                  

• Avoid enormous network payloads Total size was 2,896 KiB
  Based on HTTP Archive data, the median network payload is between 1,700 and 1,900 KiB. To help surface the highest payloads, Lighthouse flags pages whose total network requests exceed 5,000 KiB.

Drift chatbot generally affects your site performance. To overcome that issue, you can wrap the drift code snippet inside setTimeout function in javascript to load after 5 seconds delay.

                  setTimeout(function(){
                    //ADD YOUR DRIFT CODE SNIPPET
                  }, 5e3);
