I'd like to apologise in advance for my SEO ramblings elsewhere on the thread. The tl:dr version is: Hive.io is definitely not prey to a Google penalty, and its rankings are generally quite healthy at least in the US, but it's sorely lacking in other territories.

The main consideration for me is that it is relying almost exclusively on 8.1m backlinks (links from other sites to hive.io), rather than relying on having a competent organic SEO strategy implemented on the site itself. Hive's domain authority rating (SEMRush's statistic) gives us a score of '55', which is actually very healthy (60+ is considered excellent), so I think it any on-page/on-site tweaks could have a more potent impact that sites with, say, authority scores of 12.
