well i looked at your site, indeed the web site content are not so rich to get enough traffic according to the meta contents specified. Another problem is that SEO performed with your site is stuffed not smart, i mean that site has a lot of enteries in its seo that it does not contain.
Second thing is that your site is static type, I just mean by that, its just not changing by time and its some thing that make search engine feel bore and it drops its rank.
Well there are a lot to understand, if you like to work with me, please reply.
Even if you dont still reply, Regards!
