I am not sure to what extend is your SEO for this site that you say nothing has been done and yet the serp remains (presuming Google page 1?). I would really be surprised that no onsite or offsite seo including backlink building for the last 2 years and yet it performs so well. If so then there is absolutely no competition. But I wonder how long this will last though because Google likes to see fresh content on websites.
