Hello. I've never been a fan of long ads with a lot of unnecessary information. But recently I found a great website that will help you make a short ad. Here's the link:
https://xtiles.app/en/templates/company-one-pager-template Here you can use a template to make a one-page document representing your business. It's convenient, free, and safe, and it will save you a lot of time. Be sure to try it!
