Please have a look at my website. I am stuck here.

Here might be the reason. I had loads of unnecessary content so I given them the noindex tag. I tried to change the robot.txt file but that shouldn't be a problem in SEO. First my site had a country specific domain and then a year later I changed it to .Com, as to target globally (Mainly US).

My site is ranking well in that specific country  (never been close to page 1) on page 3 almost every time. It's not ranking in other countries, despite the fact that I've not targeted it to any specific country since the domain was changed.

A month ago, I deleted 404 pages and all the thin content which was indexed in the SERP and also deleted the duplicated contents and as well as the copied contents. Meanwhile I've also tried changing the headings in some of the products articles as they were causing the duplicate heading issue.

I've recently switched my hosting from the UK based server to the Us based server because the last hosting has bad downtime. So far until now nothing seems to be working in my favor. I'm just tired of resolving issues and in return finding a zero result.

This is my devil site: 10stuffs.com

plz check it out and tell me why my site is not ranking at all and what sould I do.

Wohoo, thats looks like a broken website.  I mean, the hompage is nearby empty.  That is thin content.  
And on mobile .... White burger-menu on white background? Not a good decision.

Some Content Pages look good on mobile, so its not really empty.
Chrome Console gives me a lot error-messages.
You have comparison pages and they are nothing but duplicate content.

Thats just one visit and took me one minute. I think you have a lot of problems and I bet you know a lot (from a users perspective), you need a plan how it should be and try to make a strategy how to reach that level.

Sorry I am running out of time, but there is a lot of stuff to do.

ok,  all the design or technical issues i can solve. But,  the comparision pages are common in other websites too. Do you see any other problem?
