A landing page is a great way to prototype and tests an idea, as for many services, people will first compare services based on a search they've done online.
I find that the Sales Copy Generator of Podia offers a good structure to help you create the base structure of a landing page. This tool asks you a few questions in five steps and then generates a PDF of a landing page that you can use to create your own prototype.
Lately, I've used this generator to help create the texts and then I used Typedream to create a landing page using one of their free templates.
Another inspiration that can be used when it comes to creating the texts for a landing page is the messaging framework "The Five Lightbulbs". In short, your landing page will show:
The painful status quo
What people have already tried
Your approach
Your offer
The new life people get
Service Blueprint
A Service Blueprint can be a great way to see all that it takes to build a new service and then test the idea for feasibility internally.
A basic structure you can use for your service blueprint is:
Aware: How do people discover that the service exists?
Join: What are the steps people take to get access to the service?
Use & develop: how do people use the service and develop a relationship with it?
Leave and re-join: What happens when people leave the service and when they want to come back?
