when you create a new campaign, there's an option to check potential clicks. mine usually says 20-30 clicks a day. when I click on the campaign and click on 'edit keywords', it will also have a click estimator. this one says I could hvae 100-200 potential clicks. is it normal for them to differ like that?
I think Google's estimator is way off, I wouldn't count on it. I think they estimate it hoping you have a super high quality score. But I don't think you got that so I wouldn't trust G's estimator.
