In the last year we've made a few significant changes to the structure of our site - namely adding translations for a few languages. We have historically been gaining in organic search by about 10% each month, but in the last two months we've leveled out and seen a slight dip.
I am wondering if this has something to do with the addition of the second language, and namely if there's a chance we've been penalized due to duplicate content.
We have almost all pages / content on the site translated by a translator, but the way the development works the site will grab the english version if a translation hasn't been added - potentially adding some duplicate content?
The URL structure remains the same, other than the addiion of the language - site.com/our-tour vs site.com/de/our-tour
We also haven't translated the tour name itself, so that remains the same.
Just wondering if anyone has any feedback on best practices here or things I should be looking out for.
Thanks in Advance.
