I've got a $5000/month budget set for one of my Adcenter campaigns, and am bidding $1.75 on nearly 2000 keywords and so far in Februrary have only seen about 21,000 impressions and very few clicks. This is pathetic. There is a lot of competition in this niche but damn, shouldn't I at least more impressions than 21K? Is MSN traffic that bad? I ran almost the identical campaign on Adwords and saw the same numbers over a two day period.
