What's different or special about your site? Nothing stood out to me. Your about us page doesn't tell me anything at all. Is "us" two people, or one hundred? Your contact page doesn't have a phone number or street address.
We offer free shipping and fast shipping 1-3 days. Us we are small company we huge impassioned people. We respond to the emails very fast. Please advise how we make sales.
That's the bare minimum of what people expect. Although these days I'd question the reliability of shipping in 1-3 days. I'm chasing an "overnight" delivery across my city that is probably going to be 3 days. I don't know how you can promise a Saudi Arabia to America in 3 days. Back to the basics: What is your unique selling proposition? If you can't tell me in a few sentences how you make your customers lives better then they're not going to stick around either. Your categories seem very generic. Your offerings look like you're a drop shipper not a real ecommerce site.
Warehouses in America and free shipping within 3 days What are the solutions to be able making sales ?
Shipping worldwide or just to America. You probably need to make that clear. I honestly can't suggest anything other than to work on something to differentiate your site from all your competitors. You're not going to get sales with what you have right now because it's not trustworthy, has no "hook". There's nothing for Google to grab and put you at the top of the SERPs. I've been known to google "gifts for teenage girls" but you don't have that. What about "spring cleaning essentials", nope, nothing there. Use google trends to find out what your customer searches with - but I'm sure you've already done that. You know your vision better than me, you've done your competitor analysis and know your company's strengths and weaknesses. Put that into your site, make your site stand out. Until you do you're not going to stop the visitors you can get from bouncing. Oh, and give your US address and make sure it's a real address and not a postal service or serviced office. Give your phone number. Put a chat tool on the site. Find a different way to tell people to "hurry up" because that's got to be a huge turn-off. Even "hurry" is better than "hurry up"!
