I have a blog in german. I realize that the traffic for my niche may be too small in german though... or rather, i realized my buyers tend to read the info in english. Question: how would google view my blog if i started to add english language posts? would i get penalized since the declared language is german? One SEO expert i talked with seemed pretty confident that it would actually be seen as a huge bonus by google. i'm sceptical. which is why i'm asking for a second opinion here. Any input from you guys? Thanks in advance!
