I mean if I share my products on facebook or twitter. the post will only last for a few hours correct? and people won’t be able to see them anymore? unless they intentionally go to my page right? but that is hardly the case, I think.
I shared dozens of product a day only one of them can be seen. and my friends might get annoyed thinking that I will be spamming. but this is slightly different with pinterest tho. it seems that pins lifespan is much much longer than I suspected. not all pins can survive tho.
