SEO challenges and technical issues with .store domain for niche e-commerce

Almost a year ago, we launched our site, [example.store](http://example.store), and we’ve barely been getting any impressions. The only impressions we are seeing are from India and the US. Even for the keyword *example*, our site doesn’t show up on Google. I should note that this is an adult toys store, but other similar stores appear on Google and get a lot of organic traffic, so the problem must lie somewhere else. From the beginning, I’ve suspected that the issue might be related to the .store domain. To address this, we obtained domestic TLDs, but the site is still running on the .store domain, with domestic domains handled through a proxy. While the domestic domains appeared on Google for about a week, they completely disappeared afterward. I have extensive experience with SEO and understand how things should work based on my other projects. In my opinion, the best practice would be to use domestic domains directly or a structure like *.com/fr*, without masking or using a proxy. However, I’m not entirely sure in this case. We’re constantly making improvements to the site, but I’m afraid there’s a serious technical issue with the domains or something else that’s holding us back. My other projects, which run on domestic domains, are growing consistently with more relevant impressions, but this project feels almost dead. This project is a collaboration with friends who are responsible for the domains and backend settings, so it wasn’t entirely built by me. I’m happy to share the link via DM if that helps. Any advice would be appreciated.
