I have a multi-language ecommerce site for which I am trying to improve its online marketing. There's currently a blog for the english shop, on a subdomain, which doesn't really get very much traffic. I'd been recommended to set up blogs for each of the different language shops and try to generate traffic to each of the blogs. I'm wondering if this is really worth the effort and cost (blog devt costs and ongoing translations required). Does anyone have any experience/advice on this at all? Perhaps where they've used this approach successfully or otherwise?
