If you are offering a service to create a landing page then you really need a top notch landing page yourself. Some improvements:

* Don't offer a call to action that directs straight to a signup page, it is very off-putting and you lose users there

* Put more content above the fold. There is too little useful content above the fold.

* The images are lovely but they are massive over 1MB for this one which could be less than 10kB at the rendered size in my browser https://cdn2.oneprofile.page/assets/3-b57554fe9a488e6cdc3c9a...
