Here in Brazil, when a good Portuguese equivalent word is not found for the original word or expression, Brazilians tend to use the original word — as is the case of "self service".
As far as I know, a placeholder is a default text (such as "Enter URL or search term") in web navigators, as you can see in this sample image:
- literal translation: segurador de lugar
- adaptation: preenchimento.
But I think "preenchimento" is not very appropriate for this use because the placeholder does not actually fill (não "preenche") anything, it is just a text for a void space.
So I believe that the best interpretation is "exemplo"(example, sample).
Or, in the case of a picture: "moldura" (frame) or "quadro".
I would translate your sample sentences like this:
