Daily potential reach not proportional to spend?
I just filled in the first page of the google adwords screen for a new campaign for my website www.gpxeditor.co.uk.
I accepted most of the suggested keywords and added a few.
However, if I set the budget to £1 per day, then the daily potential reach (clicks) is *lower* than if I set it to £0.50!
If I increase the budget from £0.50 then the reach (clicks) goes up and up until I get to £0.88, and then if I go higher than that the reach drops off a cliff!
I've set it to £0.88 for now then but am keen to understand this phenomenon I am seeing before I put my campaign live.
