Welcome to the Q&A Forum

Hi, this could be anything and to be honest no-one could tell you exactly why is this happening without digging deep in analyzing your traffic and how SEO are being implemented. External factors and a possible invisible Algorithm penalty (unlikely to happen) are not to exclude.

I hope someone very familiar with Moz and with experience in International SEO could tell me how reliable is Moz with keywords Ranking check. I am working on the SEO of a page that should rank in Switzerland, Germany and Austria for the same keyword in German. Moz is giving the SEO of this url: https://abfallhai.com/de/produkte-services/entsorgungssysteme/abfallhai-abfalleimer/ a score of 97/100 and I just started the backlinks campaign for it as you may have noticed. What would be your best approach when using Moz to check the ranking in the 3 countries cited above? Thank you very much.
