I think you are a starter, lots of things you have to optimise from your end… especially don’t think about the Ads- otherwise.. You will burn your money.
Initially, you can consider this.
1) The header is not looking professional:
2) The featured product does not display a quick “Add to Cart” or “Checkout” button, preventing customers from initiating a purchase immediately.
3) The footer is missing important pages such as the Returns & Refund Policy, Terms & Conditions, FAQ, About Us, and Contact Us. These are essential—especially if you plan to run Google Ads or Meta Ads in the future—and are also important from an SEO perspective.
4) There is no option to check out or add products to the cart directly from the collection page. This is important, as it allows users to add multiple products to their cart in one go.
5) The logo is too small and nearly invisible; this also needs to be improved.
6) Meta information, such as the meta title and meta description, should be within 60 and 160 characters, respectively. Currently, they exceed these limits, making the store appear less professional and negatively impacting organic rankings.
7) Your store is missing social signals. You need to build a presence on Instagram and Facebook, along with TikTok and Pinterest. Additionally, consider adding a product review app to build trust through user-generated content.
8) Use a professional email address for your store. I can see a personal ID being used, which does not look professional.
9) Consider purchasing a professional .com domain if possible. Your current domain (https://fitfuelhub.com.co/) is harder for customers to remember and type in searches, which can impact brand recall and trust.
10) Add some introductory offers to attract users, such as a flat 10% discount on the first purchase or free shipping on orders above $500. Display these offers prominently above the store header to capture attention.
11) Refine your theme and overall store design to ensure it looks professional, clean, and dynamic—creating a premium experience that builds user trust.
