I have really not put much effort into my landing page because I have been working head down on the project.
I think I have lost a lot of potential opportunity to collect an email from interested people.
I know I should probably have: a headline, maybe a sub headline, a call to action, some features, some testimonials, and a second call to action at the bottom.
I am curious if there is one thing that would make a real difference on a landing page.
What is your best tip based on your own experience with landing pages?
Other than that, I compiled a list of tips a while back that should help you get a better intuition of what you need beyond the mechanics (sure, you need a headline, but what makes it good?):

If I tried to boil it down to the basics, it's mostly about trying to put yourself in the shoes of a potential customer with very little time to waste:
* What's in it for me? => Value proposition / claims
* Prove it => Proof
