If you want to increase conversion, I recommend taking a full CRO audit. It will help you understand where exactly users are getting lost and what problems are hindering your results. The audit includes UX analysis, user testing, studying their behavior using heat maps and session recordings. It is also very useful to use conversionrate.store/cro-audit/ for more in-depth analysis. Based on the audit results, you will receive recommendations for improving the site: how to fix problems with forms, what to change in the design and what improvements will help increase AOV. This will give you accurate data to work on.
