Hi everyone,

I’m integrating Calendly into my website to allow visitors to book appointments directly. I’ve used the embed code provided by Calendly, and it’s working fine. However, I’ve noticed a slight delay in page load times since adding the embed.

Here’s what I’m currently doing:

  1. Using the inline embed option to display the booking widget on a dedicated page.
  2. My website is built on WordPress, and I added the embed code using a custom HTML block.

The problem is:

  • Page load times have increased by about 1-2 seconds since embedding Calendly.
  • Tools like Google PageSpeed Insights are flagging external scripts as the cause.

I’d love advice on:

  1. Optimizing the Calendly embed for faster load times.
  2. Whether there’s a way to lazy-load the widget so it doesn’t affect initial page rendering.
  3. Any alternative methods for integrating Calendly that might perform better.

Thank you in advance for your help!

 Hi ​@Kimpollard! Thanks for reaching out

To ensure that the Calendly embed is loading as quickly as possible, there are a few steps that you can take:

  • Ensure that the key term async is on the Javascript link on the embed code. 
    <script type="text/javascript" src="https://assets.calendly.com/assets/external/widget.js" async></script>
  • Add the Javascript code to your HTML file directly before the closing </body> tag instead of loading it with the embed code. You can see details about this here in the section Optimize Javascript Placement.
    <script type="text/javascript" src="https://assets.calendly.com/assets/external/widget.js" async></script></body>
     
  • If you are using a website builders (Squarespace, Shopify, Wordpress), they may have specific suggestion for you as well for improved performance, so I would suggest looking at the documentation for any tips they provide. 

Hope this helps - Let me know if you have any questions!
