I'm Richard - CRO Expert at PageFly Shopify Page Builder. Welcome to Shopify world and congrats on your very first store.
I can see that you are new to Shopify because your store hasn't had anything yet. You just added a theme to the store and your homepage only has element templates.
So to start, you need to add products to your store, customize critical pages (homepage, product page, collection page...). You can check this Shopify basic guide to create a Shopify store: https://www.shopify.com/blog/start-online-store
After having a basic and complete store, you can make more customization for your pages. Optimize the images, add more elements to make your page more professional, use 3rd party elements (reviews, up-sell, cross-sell...). To get more tips to personalize your pages, please refer to this guide.

Hello @k882as, I hope you are doing well! you haven't added anything in your store. You need to add products and everything in your store on the homepage. Make sure to optimize images. Currently, you have just added a theme in your Shopify store. After you build a store by adding products & everything you can add customer engagement tools in your store. Customer engagement tools are essential in an eCommerce business. It includes reviews, loyalty program, web push notifications, announcement bar, chatbot, email marketing, product recommendations & many more.
Moreover, I suggest trying out the 'All in one' Shopify app AiTrillion, a full-fledged marketing solution. It will help you to capture visitors coming to your store and will help in getting more conversions.
