new youtube channel

First of all hello everyone, I opened a new YouTube channel and in 3 days i got 500+ views and 1 subscriber, last year when i tried same thing this amount was almost twice in 3 days. I'm sure that my seo has improved , according to tubebuddy my seo score is 90 and my keyword is also low competition. I am sure i have improved but not getting same view as before any idea ?

What worked 1 year ago it doesn't work now. The trends are changing each month. Keywords are changing each month.
