If you are new to summoning, fight every summon at least once first. The first time you kill it, you get a small reward, if you draw a blue/purple summon from the daily free draw without fighting it once on the world map, you lose the chance to get a starter rune, which helps if you are a new char.

Edit:
PS. If you are asking this, you probably didnt realize that if you look at your summon list it gives you the option to run straight to them in the world map.
