I wanted to get your opinion or find out if there is any evidence around using a minimal header (logo and secure checkout icon) and footer on basket page which essentially reduces checkout abandonment.
For example... Basket (Minimal header/footer) > Checkout (Minimal header/footer) > Receipt (Global header/footer)
From some competitor analysis I have found 10/10 basket pages in the UK continue to use a global header and footer which gives users another opportunity to continue shopping. It's only when the user progresses from their basket to the checkout process where you'd find a minimal header and footer.
For example... Basket (Global header) > Checkout (Minimal header) > Receipt (Global header)
I'd greatly appreciate your help.
