Tips for creating a sale page that convert

Hi!
I’m currently writing a sale page on my website. I own a Discord servers list and my offer are 2 premiums slots on the homepage. I’ve already done a first version where I want the user to connect with his Discord account in order to continue, but it has a very low conversion rate.

For you, what are the main elements that convert on a sale page ? Social proofs ? Site stats (page views, monthly visitors) ? Somes advantages, like the options to custom the slot ? Others things ?

Sales copy is the most important element of your sales page.
Use a perticualr style of sales copy throughout the sales page.
For example here's one style of sales copy:
Direct marketing voice/style- Dan Kennedy

Focus on Social proofs, Clear benefits and make signup super easy. It don't force Discord login upfront.
