Here's how I do it:

1. Make a list of the things your service offers customers. 2. Make a list of the thing(s) you want from customers.

In your page, tell the story of your service, using the items from list #1 to get the desired result(s), list #2.

Also focus on showing instead of telling. This is a pretty common concept that most people without a writing background aren't familiar with. Imagine the difference between saying, "My service uses trusted web technologies to ensure security." and showing a collection of AWS, etc., icons.
