My advertisement is showing up half the time (adwords). I do have my ad pointing to a one page site - but it is relevent. I did bump up my PPC from $1 to $2 - even though I don't have any competition w/ in the sponsored links category. Just wondering what I'm doing wrong???
If your daily budget isn't sufficient to cover your ad showing every time the keyword is searched for, Google will show it sporadically througout the day.
