Hi! What do you think if it’s matter when I post an article, e.g., in Dutch on English speaking web-site. If google could recognize this situation and not validate my article and my back links in it?
If your website is in English then post your articles in English only don't use other languages as it will of no use from Google point of view.
Why you want to post an article in another language, post it in the same language as your website have. I think its more beneficial to your website ranking.
