It's definitely not hard to get eyes on an article, but you're probably underestimating the amount of views that Medium brings. It has excellent discovery, and based on anecdata from friends who have tried A/B testing this stuff, 90%+ easily come from Medium, especially in the 100,000+ view-range, unless you're intentionally going out of your way to spam the link to your personal site everywhere.

Also, a substantial amount of views come from search engine traffic with almost every bit of content on the internet, unless you're doing it wrong. Your most recent post is full of frequently-searched terms. It seems unlikely that little of it is coming from search engines, and almost impossible that most of that viewership is coming from something other than Medium's discovery.

Maybe try A/B testing with your next article? I think we'd all be interested in that.
