I think you can put advice into two buckets. You've got core tenets you need to follow, then there are time sensitive advice, which can only work before it's popular, or can only apply to certain time periods for other reasons. "You need a good hook", "you need to focus on a target market" is good marketing advice that even if everyone follows it, will still be good advice. "You need to be on tiktok/insta/youtube" is only good advice before too many people start doing it, and you just become part of the noise. "You need to advertise in the yellow pages" is only good advice until people stop using the yellow pages. Different from there being too many other marketers doing it.
