Welcome to the Q&A Forum

I check your site that you give me here, there is smaller links and has low as 13 Domain authority, it may happen because of site behavior, google may think that this site may performs better in search results to the users. Don't go forward if site don't have unique content and also not have better social points then site go down, you have to concentrate on your website, if you want to rank your site, you must start working on it. Build better links, Increase PA & DA, and definitely you got better ranking.
