Random spike in viewers?

I was streaming two days ago and my viewership started going up the from mid 20s where it normally is and kept climbing and ended up peaking at 131 viewers, I have done nothing different for that to happen. There was no raid. There was literally no explanation for so I’m wondering if somebody else has an explanation for it? The people were coming in saying that my name was high up on the browse page but what would cause twitch to randomly put me at the top of the page? Have they recently changed their algorithm?
