Evaluate a webshop in French/Italian or Spanish Language

As a German based Online Shop for motorcycle accessory we ship to all European countries. However we want to optimize our foreign language storeviews especially for France, Italy and Spain. - Do we use the perfect keywords for our parts? - Does our customer understand the site navigation? - Are our marketing messages and benefits clear to the customer? - Do we have obstacles or mysteries that hinder the visitor from buying? If you are a native speaking French, Italian or Spanish or are experienced in the field of Contry Management and E-Commerce we want your Expert knowledge!
