We recently launched a new design of our website and for SEO purposes we decided to have our website both in English and in Dutch. However, when I look at the rankings in MOZ for many of our keywords, it seems the English pages are being preferred over the Dutch ones. That never used to be the case when we had our website in the old design. It mainly is for pages that have an English keyword attached to them, but even then the Dutch page would just rank.
I'm trying to figure out why English pages are being preferred now and whether that could actually damage our rankings, as search engines would prefer copy in the local language.
An example is this page: https://www.bluebillywig.com/nl/html5-video-player/ for the keywords "HTML5 player" and "HTML5 video player".
