Hey there, @Tamidee!
Congrats on launching the new store! Don’t worry about being brand new; we were all in your shoes at one time or another. You’ll get plenty of great advice here.
First, the easy fixes:
Let’s start on the homepage
For reference, I’m on the Adogirl Long Maxi Dress.
You have a great start here! You are getting traffic and a few sales, and that is a wonderful start. With visitor behavior, you’ll be able to make changes that result in happier customers and more sales. Lucky Orange has heatmaps, session recordings, polls and more with a free trial (no credit card needed) and plans that start at US $10/month.
I hope this helps - good luck!
Cheers - Danny
