Looks like a neat tool, but I’m stumped on a fundamental.
Out of the options of max cpc for a keyword, it shows which I’m currently bidding (eg 0.60), and the impression estimate is about double what impressions I actually got when bidding at this value.
So I bid 0.60 and I get actual impressions of 450, but the bid simulator says that if I’d bid 0.60, I’d have got 900 impressions.
Am I missing something here?
