I went through 8 SaaS home pages and made some notes on each section so you can see what makes a high converting home page. Then I show you a Home Page template you can use to fix/improve your own home page. Check it out here: https://miro.com/app/board/o9J_kn4gZMQ=/ It's hard to say without looking at your current stats, but in my experience making improvements (like the ones I'll show you here) can add an extra 1%-2% in conversions.

What is the main problem you found on your SaaS.
