What makes a perfect landing page?

I would like to get advice on my landing page. My website provides mentorship services to professionals and entrepreneurs

I currently have the following sections:

  • Header with a call to action
  • Social Proof (Company logos where experts worked at)
  • Images of 4 mentors on our platform with their titles
  • How it works
  • What we can help you with?
  • Why Choose us
  • Testimonials
  • A call to action

Here's the wireframe - https://gomockingbird.com/projects/u99vg01

Can someone please give me some feedback on what I should include/remove?
