A few days ago I was getting 130 views per day and it was staying at around that number, it took a drop from 130 to 101, and then took a massive drop from 101 to 31 and not it's at 26.2.
Is this just my bad luck or is this something to do with YouTube?
A few things could cause this:
1) YouTube takes a while to audit its views and sometimes it seems like you're not getting any, when you really are. These usually fix themselves with a few hours, but can take a few days.
2) Your views are actually dropping. Depending on how you've been plugging yourself lately, and how much, the initial wave of views may be dying down. I've experienced a slight drop in subs myself (not counting yesterday's surge).
Check SocialBlade.com -- if your views for today STILL read zero, then it's YouTube not updating. If there are views there for the past few days, these are likely the views you've had.
Edit: Your SocialBlade looks like it's YouTube, there's a couple of weird zeroes there.
