never listen to tips like this
unless you understand what they truly mean
rewriting your failed posts is smart
but if you try to remake every old post you aren't happy with, X will slash your reach for days
mass deleting looks suspicious to the algo
delete only when you have a specific reason:
> a better hook
> a clearer idea
> something to actually fix
and do it one by one, not all at once
the tip is good, the way HOW you do it is what matters
the biggest mistake creators make is not deleting their failed posts
and no, deleting them wont hurt the algo
delete, tweak, post again, repeat until the post works
do this for a month and youll learn
> what people love
> what they ignore
> what works best for you
most of my best performing posts were failed posts lol
remember, there are no failed post ideas, only weak structure
