Hi Lisa, we've also experienced many of the same frustrations Greg mentions, but I mainly wanted to respond to your comments about not being able to compare Domain Authority over time. Given that this metric is positioned as measuring a website's overall ability to rank, it shouldn't be unexpected that people want to see how their score evolves over time. Even in your own software the change in Domain Authority since last update appears as one of the most prominent items on the Dashboard, and you also show a graph charting how it changes over time. My question is: since you clearly understand that customers want to be able to compare how Domain Authority evolves over time on a consistent scale, why not at least attempt to normalize it? I am also a machine learning engineer so the explanation "this is based upon machine learning so it will fluctuate unpredictably" makes no sense to me. You could normalize your inputs based upon certain characteristics of the population, or you could use a representative basket of websites to normalize the outputs. From what I've seen it seems that even just normalizing based on the size of your index hugely improves the consistency. It wouldn't need to be perfect to be a huge improvement over the current situation.
