We have recently found a good step-by-step guide on how to create a landing page that converts: https://marketingexamples.com/landing-page/guide
This is our updated landing page created based on it: https://scrapingfish.com
Please let us know what you think about the guide and how we implemented it on our landing page.
By the way, there are other useful resources on https://marketingexamples.com.
Looks pretty good!
Putting a results based Social Proof first can help build trust quickly and get more conversions. If people see a concrete example of how your service helped others, they're more likely to reach out to you for the service.
An example could be:
"Helped X person (or company) save Y amount of money."
Studywebdevelopment.com has good info on landing pages (and niching down) to improve conversions.
