My particular case: I have an established site that ranks in the top 5 positions on google for a set of keywords that are all in german. If I were to introduce pages in English on the same domain that target those keywords in english, what would the SEO ranking impact be? Would the rank for the german keywords drop? Would it not affect the SEO rank of the website?
My fear is that it might confuse google’s ranking algorithm because the website would no longer be as tightly focused (because it would have two languages)… what would I need to be careful about if I wanted to expand my website to a second language?
I run WP (if that makes a difference)
Does anyone have experience that they can share?
