If I have 3 addgroups with different keyword combinations like this:
[Blue Widgets]
"Blue Widgets"
+Blue +Widgets
The searcher punches in blue widgets:
How will Google know what add group to display? Will it be the add group with the highest bid?
This might be simple, but I don't quite understand how it works, how does Google chose what add group to display, if they have all the same bid?
