Common Causes of Fast Budget Depletion

In order of frequency these are the most likely causes:

1
Broad match keywords: Too wide a net means paying for irrelevant searches
2
No dayparting: Without ad scheduling budget gets spent in low-value overnight hours
3
Smart Bidding over-bidding: Target CPA or ROAS strategies over-bid when lacking enough conversion data
4
Low Quality Score: Poor Quality Score means paying more per click for the same position
5
Increased competition: More bidders raise minimum bid prices

How to Fix Each Cause

Address each cause systematically:

1
Broad match: Add negative keywords aggressively or switch to phrase or exact match
2
Dayparting: Add an ad schedule excluding low-conversion hours typically late night
3
Smart Bidding: Review Target CPA or ROAS targets and confirm they are realistic
4
Quality Score: Improve ad-to-keyword relevance and landing page load speed
5
Competition: Use Auction Insights to understand if new competitors entered
