Why is my site doing OK in search, where as my forum is terrible?

[Pavle123]

I know there are many things to consider in this.

But it is a bit strange that my site is doing so much better in search, where as my forum (which is on subdomain) is nowhere to be found?

Proof
Site

Forum

My forum link is here http://goo.gl/sLIQY

Obviously something is wrong from the technical side?
Could Brivim plugin called Advanced No Index which I use to noindex trhreads which are low in quality (less than 300 words) be making problems?

I would really appreciate the help.

If this trend continues, I do not think I will be spending time on investing and building forum anymore. So I beg you guys to help me with SEO and my forum.

Google WMT/search isn't really an XF support issue.
