Is boosting a post enough, or is Ads Manager better?

Boosting a post works as a short test of a piece that already brought messages, in a small radius. Ads Manager is what you need when there is more than one piece and a neighbourhood audience, and a campaign should not open if the piece never says how to book. Separate the piece that already worked organically from the one that only has empty reach. A campaign opens with four different ads and none of them says the street. The boost test stays on one piece and one area. If it is repeated, it moves into a set with the same booking link.
