Let users try your product on their websites so they can see how it works and fits in with their brand and aesthetic, along with discovering it's features. We're often told that actions speak louder than words, and it's just as true in this instance.
For example, a live chat software company might introduce a Try it Yourself widget which you can use by pasting your URL, and the widget will return a simulated version of your website with their live chat software on it. This is a great way to show users how the software would look, feel and function on their website.
