🔍 The 7 Budget Leaks Killing Your Google Ads ROI
Leak 1
Broad match keywords without Smart Bidding data. Use broad match only once you have 50+ conversions per month feeding the Smart Bidding system meaningful data. Otherwise you burn budget on irrelevant queries.
Leak 2
No negative keyword list. Without negatives, ads show for competitor names, job seekers and irrelevant queries. Build a 200+ negative keyword list from the Search Terms report within the first 2 weeks of every campaign.
Leak 3
Sending traffic to the homepage. Homepage conversion rates are typically 1-2%. A dedicated landing page aligned to the exact keyword converts at 5-15%. This single change can 3-5x your ROAS overnight.
Leak 4
Running ads 24/7 regardless of conversion patterns. Check your hourly conversion data. Most B2B clients convert during business hours. Ad scheduling saves 15-25% of budget by focusing spend on high-conversion windows.
Leak 5
No conversion tracking. If you are not tracking conversions, Google has no signal to optimise toward revenue. Set up conversion tracking for form fills, calls and purchases — then switch to Target CPA or Target ROAS bidding.
Leak 6
Ignoring the Search Terms report. Review it weekly. Every irrelevant query triggering your ads is money wasted — add it as a negative keyword immediately. This single habit saves 10-20% of most budgets.
Leak 7
Low Quality Scores (below 6). Quality Score directly affects your CPC. A QS of 10 gets the same position as QS 5 at half the bid. Improve QS by tightening keyword-to-ad-to-landing-page relevance within tightly themed ad groups.
