How can I improve my online store and is switching to a paid theme beneficial?

Hello! going through your web store I believe that there is genuine need of User Generated content/ social proof for your business.

Displaying your current customers’ experience on your store will build trust for potential customers as well as increase your conversion rate/LTV.

Note:- Use Idukki app on app store to build beautifully designed widgets and add to your store without writing a single line of code!

In addition,
PDP’s need more than just one image.
