Embedded views don't send the "/get_video" request which updates the "fake" view counter. All views take time to update. There's two view counters. One is a fake/inaccurate one which is incremented by simply sending a request to "/get_video". Zero checks are done on this and it's incredibly easy to increment this. This counter means absolutely nothing and is only for display purposes (only the /watch page will increment this counter). The other view counter is the real view counter that updates every 10+ hours or so. When the fake view counter has hit 300 views, it freezes and can no longer be increment. When the real views counter has passed 300 views, the views displayed will switch from the fake view counter to the real one, and the fake view counter will no longer be used.
tl;dr, the fake view counter (the one that updates instantly) means jack shit. Has absolutely no impact on SEO or video popularity/viral/etc.
