Hi,
I have a serious problem with the domain Spam Score (44%) which seems to have a direct impact on the website ranking nationwide in Germany. The domain itself is not Spammy as I managed to disallow all the unwanted Backlinks and the domain is not penalised by Google Search Console. It ranks very well locally for local keywords but would not show among the 100 positions nationwide as it used to do a couple of years ago, even if I implemented the right SEO strategies and the right backlinks, it just doesn't rank in Germany for national SEO.
This is the website in question: Übersetzungsbüro Kaiwords, do you think there is a way to lower the Spam Score, is there any chance that the website ranks again for national SEO?
