Insert tracking snippet in Astro for performance metrics

[sharp ermine]

I am trying to make a case against WordPress. Astro is so much faster than WordPress. I am testing with Pingdom and their "Real User Monitoring". They ask me to put this snippet on my page:

<script src="//rum-static.pingdom.net/pa-671d36847a5fd400120000de.js" async></script>

I am unsure how to do that with Astro in an elegant and efficient way. Any ideas or hints to the docs where I could read this?

I have started to read this page. But I am unsure what to make of it: https://docs.astro.build/en/guides/client-side-scripts/#using-script-in-astro

Does it need to be on every page?

And do you have a layout file in your project?

if you have a base layout you use for each page you could drop the script in there

If you only need it on the landing page for example you could drop it in index.astro
