PostEaseSteady beats sporadic
Since Pinterest is a search-driven platform where a Pin can keep earning traffic for months, a consistent, sustainable pace of new Pins tends to serve an account better over time than an intense burst followed by long silence. A steady trickle of fresh, relevant Pins gives the system a continuous stream of new content to match against search intent.
Quality matters more than hitting a specific count
A handful of well-made, useful Pins outperforms a much larger volume of rushed ones, since Pinterest's ranking cares more about whether a Pin gets saved and clicked than about how many were published. No minimum count substitutes for a Pin being worth saving.
A realistic starting cadence
A small number of new Pins per week, kept up over months, is a sustainable starting point for most accounts. It is more likely to run long enough to see the compounding effect Pinterest rewards than an ambitious daily pace that burns out after a few weeks.
