Congrats. In addition to finding a mentor, I would suggest check out Google Analytics Academy. They have a few free courses, which you can get certificates for in short turn around (can take them in a few hours). This help our team during an e-comm venture project. You can get a sense of all the important data on your e-commerce site - website visits, mobile visits, abandoned carts, most visited pages, products, etc. You can assess keywords, filters, etc. to gain more insights into your CAQ, how to improve CLTV, retention, google ads and more. It can help you in figuring out ways to optimize and lower your costs, as well as strategize more favorable ways to keep winning with sales. Also remember - content is king. Good luck!
