wix seo for online store

As an online business owner, I want my store to be seen by as many people as possible. To do this, I need to create an SEO optimized website on Wix. Unfortunately, the store has been created but is not yet optimized for SEO. My specific goal is to increase organic traffic through targeted keyword research and improved search engine ranking. I need help finding the right keywords to target in order to achieve this goal, as I do not yet have any preferred keywords.
