Have you checked your keywords? And Have you optimized it to some similar keywords? If not, maybe there's something wrong with the SEO. I should recommend you to check your sitemap and most of all your keywords (meta tags). Lastly, if there's nothing technical, someone has ranked more than yours. (IMO)
