According to Google’s John Mueller, if a brand has multiple versions of its site under the same domain name, they can influence each other.
Suppose Google deems one version of a site in a particular language to be of low quality compared to the other version in another language. In that case, the former can negatively impact the latter. But this has little to do with different site versions having translations of the content.
Google looks into the overall quality of the site. “If we see that there are significant parts that are lower quality, then we might think overall this website is not so fantastic as we thought,” explains Mueller. As a result, it will impact Google’s analysis of different places across the website.
