Google Ads · Spend dropped

Why did my Google Ads spend drop?

Google Ads spend drops when campaigns lose impressions: a budget change, bids or targets set too tight, lower Ad Rank, narrower targeting, or ads and assets disapproved. Adstudio finds which campaigns stopped spending, reads impression share lost to budget and to rank, and checks the change history and review status for the same days.

The numbers that matter

What to read first.

Cost by campaign by day: Shows the day spend stopped and which campaign stopped.
Search lost IS (rank): Rising rank-lost share means bids, targets or quality are holding the campaign back.
Search lost IS (budget): Falling budget-lost share with lower spend means the budget is no longer the limit.

The method

How to break it down.

01Find the day the spend fell and the campaigns that account for it.
02Check status and review: a paused campaign or disapproved ads stop delivery at once.
03Read impression share lost to rank and to budget for those campaigns.
04Line up budget, bid strategy and target changes from the change history.

How Adstudio answers it

In the app, or from the AI you already use.

In the Adstudio assistant

The assistant reads spend by day and campaign, impression share lost to budget and rank, the review status of ads, and the change history. When the cause is a budget or a status, it prepares the change on the verified Google path and applies it after you confirm.
