Redbubble Data & Performance, page-53

If the data is terrible, any half-decent fundie would pay the "tax".

It's good that you've diversified your data sources, but it does still seem to be quite Alexa-heavy.

I've recently had Alexa tell me a website with <1m in traffic a month is in the top 2000 global rankings, so I am very disappointed with the quality of their rankings data. I won't disclose the website, because it's also a listed comp that I am thinking of purchasing. It was only after using 2-3 other data sources, that I get an accurate picture of traffic and engagement.

The google play app download is a useful indicator of new users (or those who may have upgraded their handset or switched from iOS), but it is an imperfect indicator of purchases, whereas traffic is arguably better.

In summary, Alexa sucks and you don't have iOS or mac data (neither do I), which is where the millennial $$ is at.
