Welcome to the Q&A Forum

Good to hear no performance issue. Obviously that is priority number one.   Definitely don't sweat the render.  You might want to refetch and see how it looks. also give it shot with mobile fetch to see if you get anything different. A lot of us are chasing the position zero snippet.  I didn't look at your site closely but i would start by making sure that every single item (as appropriate) is marked up with schema.org.  That will put you closer to your goal

My first instinct is obviously to say "if you lose 50-75% of your links, will your rankings drop" - well ... yes? I mean that seems fairly obvious? But I didn't want to be that obtuse so I thought about it a bit longer. And really, the question is much more teachable than that over-simplified answer. What you are talking about is domain-level vs. page-level link factors. ANY link to your site affects the whole domain (domain factor) but a direct link to an inner page has more page-level effect. If you look at the Moz Ranking Factors Survey you will see this: Domain-Level, Link Authority Features: Based on link/citation metrics such as quantity of links, trust, domain-level PageRank, etc. And that, right there, is your answer. On the domain-level, we assume quantity of links, trust & PR of those links affects the domain as a whole. If you have poor quality links it can also tank the whole site even if they all direct to one inner page. So yes, the long answer is "quantity and quality of links can affect domain-level metrics and thus affect your rankings."

Hi Christian! Besides the other great answers provided above, it looks like this is likely caused by server errors, and also the fact that these links seem to be blocking user-agents. Are you able to make adjustments to either of these? If you have further issues, please write into help@moz.com and we'll take another look. Thanks! Kevin Help Team

Perhaps they should look at re-branding the product offering before they look at ranking. Take a look at this inspirational video by Rory Sutherland.
