Facing issues with NewsPaper theme SEO

I bought newspaper theme long back and added on a site which is reeviewz. Till date I have got 184 articles and traffic is very less. On a different website which is top10reviewz I added Schema and getting very good load time and traffic. Can someone help me on this. I still love newspaper theme a lot and dun wanna waste my money spent on this one
