help with my sales letter - low conversions! | warrior ... - putting on a facial mask

Hello my IM is not good I always like to focus on AdWords and links --
Instead of perfecting my sales page.
After realizing that many people do have a higher conversion rate than I did, I decided to try to make the page better.
I got about £ 1% but many claim £ 1.
5 to 2% is entirely possible without major reconstruction.
I would like some feedback from experts in this regard.
Any general or detailed comments (font, color, length, etc ).
) Would be grateful.
I was surprised to see people link directly to their sales page here --
I want to avoid it for SEO (and business) purposes.
Thank you in advance for your help!
