Honestly, it looks like a parked website. You should adjust the header to your theme, unless you want to sell flowers on the domain.
sorry i cant understand the language in the website, but the design is poor try to make it look like a website and not a blog, the categorie bar isnt good, the adsence emplacement isnt good ,the boutons arnt good either, do some design changes, or just download a ready template and make some modifications
Awesome look & feel. Navigation of the site is very much user-friendly. Rewrite your Meta Title with our most important keywords (within 65-70 characters). Another point is that I've not found your sitemap.xml file.
