I need someone to give me his first impression on my store and to tell me what i need to change to start getting sales as im already doing some facebook ads and getting clicks but still 0 sales.
Getting clicks without sales means the issue is your store’s ability to build trust, which is fixable.
First, this would just take a few clicks, add a favicon to your site. Use this page for your instructions.
Next, consider buying a domain name. The default .myshopify.com URL might be a reason that new customers will not trust your store. This is a small cost for a massive improvement in professionalism.
Lastly, to be honest, your site currently looks very new and generic. My recommendation is continue working on your store, make it stand out and pause the Facebook ads until you have improved on your store identity.
All that @PieLab said is very true. Have you seen any store from myshopify subdomain that is either a test store or a fake/scam store? Finding a domain is hard, but that investment is a must.
Also getting products and some description is a good start, but just a base. You need to show your store as trustworthy, and currently, there are not many good signs for that. No reviews, yeah, I know it is a new store, but still, no contact information, except for some Gmail email that does not bring any trust and one address. But then on product pages, you have some other email and address in Cyprus, from a supplier or what?
And one thing about design, maybe that is just me but I think all prints would look better if you had a transparent background not a black one. This way you see a box, and to me that does not look great.
You can use some more collections and better navigation, both in header and footer. Also do not use words like “Cheap price” it is a negative word, does not bring value. Use affordable instead.
Also, spend some time here in the community, search for “no sales” and check tips that are given to store owners like you. Some you can apply to your store and make it better.
