load one-off page fast I want to create a landing page for my Google Ads on my site so that potential customers will be able to download and see the page very quickly. My site can be a bit heavy with CCS and javascript and other stuff sometimes.

All I want is to avoid losing potential clients due to a slow website. So I wonder if there's a simple way of the landing page being a light version of my site (with links to the "real" drupal site).

Many thanks

If you want your website to load fast, you need to cache.

Go to Performance (/admin/config/development/performance)

and enable caching and aggregate css and javascript
