Here are my lifetime YouTube viewcounts:
2015 isn't over yet, so that number is just an estimate. I'm currently at 4,822,171 views this year.
Clearly, I peaked in 2011, the year of Nancy Drew: The Captive Curse and Nancy Drew: Alibi in Ashes. Ever since then, I've been steadily getting fewer and fewer views. I'm not sure where the dust will settle. Maybe things will stop at four million views, and my channel will hover there in perpetuity.
I dunno! I've tried stuff to turn things around, like branching out to book reviews and livestreaming for the 2014 Nancy Drew Games Mega Marathon. That marathon is STILL the most-watched thing on my YouTube channel, even though it's a year old now. But it wasn't enough to stop the general fallout.
Any suggestions as to what I should do? My subscriber count, interestingly enough, keeps increasing and has never gone down. So there are more people following my channel, but I guess they're watching fewer videos.
