i made a new ppc campaign on Bing Ads .It had only one ad group with around 150 keywords with a bid of $1. I got some 700 impressions .The average rate of impressions per hour was around 60 .
Next day i did not changed anything and my impressions volume falls steeply like around 10 impressions / hour
The same thing is continued next day with increased bids but the impression volume is really low .
can anyone have any idea what is happening ? Its a new campaign only 3 days old now .
