Hi there,
I looked at your site, looks good. I also ran your site through I tool I recently discovered (it might be an old tool but still).
http://nibbler.silktide.com/en_US/reports/www.clickdesk.com
It gives you a report about your site looking at coding, social media accounts and reach, localization features etc. It might not be the best software or not a bible of internet marketing but it does give you quite a interesting view on things. I recently solved a lot of problems with different websites which helped me rank better but internet marketing is not an exact science as you just might know.
Hope it helps some
Regards
Jarno
