Google Ads Quality Score Optimization for 2026: The Small Business Playbook
If you're a small business tired of agencies that run your ads without fixing the root cause of high costs β this guide is for you. In 2026, Google Ads Quality Score (QS) isn't just a metric; it's the gateway to lower CPCs, higher ROI, and smarter AI bidding.
π― Why Quality Score Still Matters in 2026
- β Google's AI-driven Smart Bidding incorporates QS to determine ad rank and CPC.
- β A high QS means you pay less for better placements.
- β A low QS = higher CPC, worse placements, wasted budget β no matter how smart your bidding strategy.
π Think of QS as your ad's credit score β bad score = higher costs, lower results.
