1. Use real Content while working on the web typography
The very first thing you should do is to dump the Lorel Ipsum [Dummy Text] text while working on the typography design. The reason I am keeping this rule because there is a huge difference in the dummy text and real content.
You may not experience the actual look of the content when you are having dummy text thus using real content should be preferred so that you can see what will display actually to the audience.
So you should ask your client to provide actual content before proceeding with typography design.
