Hi,
It's a bit dificult for me because your site is non english, but let's try
1. You need to review your home page keywords. Try to find 2-3 keywords that best discribes your shop in common,
i.e. "Military equipment | Camping equipment |Online shop magazinoutdoor.ro" or something like that.
2. Create and submit sitemap.xml to google webmaster tools
3. Put in your logo "alt tag" sentence with the keywods.
4. I didn't find heading tag h1, h2 in your site. You can easy to do this with editorial module, write few sentece about your shop using keywords.
4. Write meta tag description more friendly for the visitor, not only stuff with the keywords.
5. You wrote that you are targeting with the keyword "bocanci militari" and I see that you are on page 3 in google. To reach better positions try to get some backlink to your page http://www.magazinoutdoor.ro/29-bocanci-militari . Make this category description more friendly and informative to visitors, not only fill with keywords.
That would be my suggestions, hope it helps
Good luck
