can u follow ppl on pinterest from certain country

i was wondering if there is a was to follow someone on pinterest from certain country, so i dont waste my time following or click follow for no prospects

Interesting question. There are no filters for countries, but perhaps you can search for boards in the language of the target market you're seeking. So for example, instead of recipes, search for "la receta" for Spanish-speaking demo. Then follow the owners of those boards.

I've been trying to figure this out. For example, if I search for "Architecture Australia", I can see boards and accounts that post about that but there's no way to filter it out to just those who posted from Australia. Maybe I was wrong. Maybe someone more experienced can help us.

There is no such filter, but you can do some workarounds.

a) language: set the language to the target language and enter pinterest via that subdomain (e.g. de.pinterest if you'd target Germany). your smart feed should show you more or less targeted stuff
b) find big, local accounts (like newspapers etc)...they are bound to have an approximate local following as well
c) find local specialities that only local are interested and filter accordingly.

i think that is all you really need.
