Gary Illyes from Google said on Twitter that most algorithm updates done by Google go "unnoticed."
I am not sure I agree, with that, I mean I cover a ton of stuff here and I honestly do skip a lot of the small stuff. But there are times Google said we missed something that launched X months ago and I look at my archives and we covered those blips.
Maybe most searchers do not notice, but I'd think it's better to characterize that as they do not care versus do not notice.
Here is the tweet:
@SimpsonGareth it depends. Most algo updates go unnoticed, but we may communicate about the named ones, like mobile friendly.— Gary Illyes (@methode) May 5, 2016
If I am missing stuff, I better step up my game and cover more of these small blips. :)
